Section 1: Plant-Based Odour Neutralization Technology
1.1 Introduction to Advanced Odour Control
Traditional odour control approaches often fall short in two critical areas: they either function as temporary masking agents without addressing underlying chemical reactions with malodorous compounds, or they eliminate odours while introducing hazardous substances into the treatment environment.
Anotec’s plant-based odour neutralization technology offers a scientifically validated alternative that achieves genuine odour elimination through multiple functional mechanisms without relying on synthetic fragrances or toxic chemicals.
1.2 Essential Oil Science and Mechanisms
An essential oil consists predominantly of volatile compounds isolated through physical processes from odorous botanical sources. Over 3,000 essential oils have been identified from diverse plant species, with several hundred commercially available. These oils derive from various plant components including leaves, fruit, bark, roots, grasses, wood, flowers, seeds, and buds.
The geographic origin of botanical sources significantly influences essential oil composition and efficacy. Identical plant species cultivated in different regions may produce oils with varying chemical profiles and performance characteristics. This variability necessitates careful sourcing and quality control to ensure consistent odour neutralization performance.
1.3 Product Formulation and Function
In typical airborne applications, Anotec’s plant-based odour neutralizers are atomized or vaporized into the atmosphere where formulated droplets attract or are attracted to airborne compounds including malodours and particulates. Research has identified multiple mechanisms through which properly formulated plant-based products achieve odour neutralization:
- Adsorption: Malodour molecules attach to the surface of atomized droplets through weak electrostatic attraction forces.
- Absorption: Malodorous gases dissolve into the liquid phase of droplets, becoming encapsulated within the formulation matrix.
- Solubility Enhancement: Formulated blends significantly increase the aqueous solubility of malodorous compounds that exhibit poor water solubility in pure systems.
- Distribution Constant Enhancement: Once malodorous gases dissolve into atomized droplets, the formulation increases the liquid phase’s capacity to retain dissolved gases, favorably affecting equilibrium distribution according to Henry’s Law.
- Chemical Reaction: Direct chemical reactions occur between essential oil components and malodour compounds, producing non-volatile, odour-free products.
1.4 Solubility and Distribution Mechanisms
Chemical reaction represents only one mechanism through which Anotec’s plant-based formulations control odours. Before reactions can occur, malodorous gases must first dissolve into atomized droplets containing active essential oil components. Solubility therefore constitutes the primary mechanism in odour control effectiveness.
Industrial malodorous gases exhibit wide-ranging water solubility characteristics, from “very slightly soluble” compounds to “very soluble” gases like ammonia. Anotec’s plant-based formulations demonstrably increase the solubility of most malodorous gases in aqueous systems.
1.5 Specialized Formulations for Neutral Hydrocarbons
While broad-spectrum formulations effectively address acidic and basic malodours, neutral hydrocarbon compounds such as styrene require specialized essential oil blends. These formulations are specifically designed to enhance styrene solubility in aqueous systems. Although not initially designed to chemically react with styrene, research discovered that oxidation reactions do occur between styrene and water when styrene solubility is measurably increased through specialized formulation chemistry.
1.6 Safety and Environmental Profile
Comprehensive testing by independent laboratories establishes that Anotec’s properly formulated plant-based odour neutralizers are non-hazardous according to international hazard communication standards. Products contain no hazardous Volatile Organic Compounds (VOCs). While essential oil components are naturally organic and exhibit some volatility, volatile matter content in properly diluted formulations typically measures less than 2% of total volume.
Products undergo rigorous testing following international guidelines including:
- Material Safety Characteristics
- Human Toxicity Testing
- Acute Oral Toxicity Studies
- Acute Dermal Toxicity Studies
- Acute Inhalation Toxicity Studies
- Acute Eye Irritation/Corrosion Studies

Section 2: Odour Generation and Characteristics
2.1 Understanding Malodours
Odour is defined as a sensation resulting from stimulation of olfactory organs, whereas “an odour” represents the subjective experience of perceiving a smell. The property of a substance affecting the sense of smell is termed an “odorant” or “osmogene.”
Significant individual variation exists in odour detection capabilities. Many people cannot detect specific odours while exhibiting high sensitivity to others. Some odour-bearing substances in weak concentrations cause more intense olfactory responses than in strong concentrations. For instance, hydrogen sulfide (H₂S) is easily detectable at low concentrations, but at concentrations exceeding 400 ppm, H₂S overcomes olfactory senses, becoming odourless to humans while simultaneously becoming lethal.
2.2 Principal Odour Sources
Odour-producing substances in domestic and industrial wastewater, sludge, and process streams typically result from biological activity. Most malodours originate from anaerobic decomposition of organic matter containing sulfur or nitrogen. Sewer gas commonly includes hydrogen sulfide, ammonia, carbon dioxide, and methane, often accompanied by highly odorous indoles, skatoles, mercaptans, and amines.
Malodorous substances generate in any location where anaerobic conditions can develop in wastewater or solids deposited as scum or sludge. Deposits prevent sufficient oxygen diffusion, quickly transitioning to anaerobic, odour-generating conditions. Odorous substances readily adsorb onto dark, coarse, porous surfaces, which subsequently emit odours for extended periods.
2.3 Hydrogen Sulfide: The Primary Industrial Malodour
Hydrogen sulfide (H₂S) represents the most commonly encountered malodorous gas from domestic and industrial wastewater systems and chemical processes. It is highly soluble (2,800 mg/L at 30°C to 5,650 mg/L at 5°C) in typical wastewater streams.
Beyond its characteristic rotten-egg odour, H₂S creates highly corrosive conditions and represents an extremely toxic substance. Water droplets or condensation on surfaces containing dissolved H₂S form sulfurous acid (H₂SO₃) and sulfuric acid (H₂SO₄) through bacterial oxidation, both highly corrosive to paint, concrete, metals, and infrastructure materials.
The toxicity of H₂S approximates that of hydrogen cyanide (HCN). Death may result from exposure to H₂S concentrations of 225 ppm by volume. Maximum permissible exposure for 8-hour working periods is 10 ppm. Hydrogen sulfide is particularly treacherous because olfactory capability to sense high concentrations is quickly lost.
2.4 Odour Transmission Dynamics
Odour transmission requires three components: a sender (odour source), a carrier (typically air currents), and a receiver (human olfactory system). All substances with measurable vapor pressure potentially emit odours. Human olfactory systems cannot detect most odorous messages due to limited receptor capabilities.
Odour detection capability depends on multiple factors:
- Concentration of osmogenes
- Distance from osmogene source
- Air current strength and direction
- Individual physiological condition and adaptation state
Odour vectors may be stationary objects with adsorbed osmogenes or airborne particles. Adsorbed odours continue as odour sources for extended periods, sometimes years. Clothing often retains odours despite intensive washing. Buildings formerly occupied by malodorous industries continue emitting odours from apparently clean surfaces.
2.5 Impact on Human Environment
Humans distinguish over 5,000 distinct odours. Odours can alter or create moods, with documented effects including increased heart rates, elevated respiration, blood pressure changes, and even pain perception. Continued exposure to malodours can eventually cause olfactory apparatus atrophy. Odour perception links deeply to memories of past events, triggering recall of both pleasant and unpleasant experiences.
While humans no longer depend on odours for danger warning, food location, or social bonding, odours remain important to quality of life. Increasing population density in urban areas creates odour accumulation far less dispersed than historical rural settings. People associate specific odours with human waste, spoiled food, disease, or unpleasantness.
Section 3: Odour Control Methodology
3.1 Introduction to Odour Abatement Technology
Odours represent byproducts of numerous industrial processes. Because odour control typically functions as an expense rather than revenue item, it often receives attention only after public pressure or regulatory enforcement. Anotec’s plant-based odour neutralization presents an alternative to traditional odour control approaches, which in some cases pose dangers to workers and environments while not always achieving complete effectiveness.
It is essential to distinguish between odour control and emissions control. Odour control addresses nuisance odours disturbing neighbors or employees. These odours consist of gases that should be measured instrumentally. However, when treating malodorous gases with Anotec’s neutralizers, gases may remain measurable by instruments while no longer perceptible to human olfactory systems. The human nose represents the optimal odour control instrument, as odour elimination aims to prevent human detection rather than achieve complete molecular removal.
3.2 Comparison of Available Odour Control Technologies
Chemical Scrubbers: Scrubbing systems combine acids, caustics, oxidizers, and surfactants in controlled environments to eliminate odours. While mechanics can be monitored and controlled precisely, disadvantages include potential chlorination effects producing chlorine gas, requirement for corrosion-resistant construction materials (stainless steel or composites), substantial capital costs, complex operation requiring trained personnel, and application-specific design limitations.
Activated Carbon Adsorption: Adsorption processes retain organics on granular solid surfaces with large surface-area-to-volume ratios. Activated carbon effectively adsorbs sulfur compounds, aldehydes, and ketones. However, effectiveness varies with carbon grade and source material. Considerations include preferential adsorption effects, internal heat generation and fire risk, critical contact time requirements, and expensive disposal of saturated toxic media requiring encapsulation.
Ozone Oxidation: Ozone represents one of the most powerful oxidants available. However, ozone is toxic, explosive, and effective only for narrow malodour spectrums. Complete systems require ozone generators, monitors, and destroyers, making installations expensive. Ozone is better suited to process effluent treatment than general malodour management.
Biological Filters: Biofilters utilize microorganisms to oxidize odorous compounds, consisting of containers packed with organic media saturated with bacteria. Advantages include effective organic compound degradation. Disadvantages include large physical footprints, sensitivity to flow and temperature variations, bacterial mortality from surge conditions, 100% humidity operating requirements, and periodic media replacement (every 3-6 months).
Thermal and Catalytic Converters: These systems burn odorous waste gases at high temperatures, potentially creating dioxins and furans. While effective against certain organics, systems are expensive, require complex operation, face catalyst saturation and sterilization issues, and demonstrate reduced effectiveness against hydrogen sulfide and ammonia.
Incineration: Incineration subjects industrial waste gases to very high temperatures (800°C+), breaking down molecular structures. The process is dangerous, expensive, not entirely effective, and typically introduces oxides and chlorinated compounds into atmospheres.
Anotec’s Plant-Based Chemical Odour Neutralization: Anotec’s plant-based neutralization offers economical alternatives combining physical absorption with sensory modification of malodour molecules. Unlike masking agents superimposing pleasant fragrances over unpleasant odours, Anotec’s plant-based neutralizers absorb and convert malodours, resulting in complete odour elimination.
Performance depends on malodorous compound types, concentrations, and human detection thresholds. Anotec’s products effectively address broad malodour spectrums including hydrogen sulfide, ammonia, sulfur dioxide, mercaptans, amines, styrene, and other challenging compounds. Formulations are completely biodegradable and safe for people, animals, and plant life. Products add no harmful VOCs to emission sources and do not react to create air pollution problems.
3.3 Application Delivery Methods
Anotec’s odour neutralizers do not require complex, specially designed equipment because they are multifunctional, broad-spectrum, and completely non-hazardous. However, system engineering remains important. Whether dripping, fogging, dosing, injecting, or scrubbing, appropriate application equipment is readily available and easily specified.
The most suitable delivery method is determined by several factors:
- Type of odour requiring control
- Odour emission source characteristics
- Area size requiring treatment
- Existing odour control hardware presence
- Ambient or process gas conditions
- Location of areas requiring protection (typically people)
- Engineering facilities flexibility
Anotec’s aqueous formulations achieve maximum effectiveness when atomized into odorous process air or open air near malodour sources. Since products are not masking agents, the primary challenge involves applying products effectively to enable odour neutralization. Consider operational mechanisms: malodour molecules and product droplets must contact each other or approach closely enough for electrostatic attraction. Ultimately, malodours must adsorb onto droplet surfaces and/or be absorbed through solubility mechanisms.
3.4 Application Equipment Types
Atomizing Nozzle Systems: Fixed nozzle installations represent the most common dispersal method for diluted formulations into atmospheres. Several manufacturers produce nozzles atomizing products to adequate droplet sizes for reasonable efficiency. Once atomized, products disperse into air streams with opportunities to locate and react with malodours.
Portable Atomizers: Hand-pumped atomizers (agricultural and pest control types) deliver products to areas not requiring constant control, for topical applications, or where power is unavailable. Small electric handheld atomizers address localized areas of varying sizes. Portable fogging machines offer maximum portability and coverage with minimum investment.
Hollow-Blade Fan Systems: Hollow-blade fans originally designed for agricultural humidification disperse diluted or concentrated formulations into open air. Systems include oscillators ensuring even distribution. Primary applications include enclosed areas up to 300 m², with series installations covering larger spaces.
Vapor Phase Systems: True vapor phase systems provide simple, effective methods transforming products into vapor states easily transmitted into malodorous environments. Systems vaporize products for maximum utilization without large water volumes. This proves critical where added moisture and humidity are unacceptable.
Scrubbing Systems: Anotec’s products can replace various odour control chemicals in scrubbing systems, offering environmentally friendly substitutes for dangerous chemicals. Prior investigation of regulations and requirements may save substantial costs by avoiding expensive scrubber installations when simple injection or fogging processes using Anotec’s plant-based formulations meet or exceed local emission regulations.
3.5 Application Technique Guidelines
Design engineers have two options when specifying nozzles: utilize recommended nozzles or specify custom selections. Engineers specifying custom nozzles must ensure droplet sizes below 25 microns, optimally below 10 microns. Numerous nozzle manufacturers claim fine spray capabilities, but not all provide optimal atomization.
All atomization systems, especially nozzle-based systems, require careful attention to supply water quality. Atomization nozzle designs typically include small orifices (0.2 mm typical) and narrow passages (0.5 mm common). Untreated potable water inevitably causes nozzle blockage. Water with Total Dissolved Solids (TDS) exceeding roughly 200 ppm or high calcium content should be treated to prevent excessive blockage.
Section 4: System Design and Equipment Specifications
4.1 Hydraulic High-Pressure Systems
Hydraulic high-pressure systems represent the preferred choice for most outdoor installations and many indoor applications. These systems provide excellent atomization through specialized nozzle design, are simple to specify and design, and are straightforward to install. Systems should always be specified with adjustable, automatic product proportioning, injecting concentrated product into low-pressure water streams.
System Components: Atomization nozzles commonly install in flexible 6 mm ID hose with various nozzle spacing options. Stainless steel hose may alternatively be used. Flexible feed/manifold lines are typically 6, 10, or 12 mm diameter, depending on flow requirements and line length versus pressure drop considerations.
Nozzle Plugging Prevention: Nozzle plugging concerns exist in all atomization systems. Attention to water quality and effective filtration helps prevent this issue. Standard high-pressure systems include at least two filtration stages: 20 micron and 5 micron. System designs must specify this filtration level.
System Sizing and Selection: To correctly size and specify hydraulic high-pressure systems, first define the coverage area and atomizing nozzle locations to ensure product contacts malodours. For open-air installations, engineers must consider nozzle location relative to odour sources, areas requiring protection (neighbors), prevailing and secondary wind conditions.
4.2 Pneumatic (Compressed Air) Atomization Systems
Compressed air atomization nozzle systems provide excellent atomized product delivery methods. Systems are simple in design and easily installed. The primary advantage involves superior control capability: higher air pressure produces smaller, faster droplets, while higher liquid pressure increases product volume, offering suitable dual-operation systems.
System Design Considerations: Pneumatic atomization utilizes air atomizing nozzles manufactured by major suppliers. Compressed air mixes with liquid streams within nozzles, producing completely atomized spray. System design follows pneumatic engineering principles addressing pressure regulation, flow control, compressed air quality, and pneumatic plumbing.
Air Consumption Analysis: When specifying air atomization systems, carefully analyze air consumption to avoid placing significant loads on facility compressed air systems. Proper header sizing is essential. Common nozzles operate at 140-210 kPa pressure ranges for both liquid and air.
4.3 Hollow-Blade Fan Systems
Hollow-blade fan systems originally developed for agricultural humidification effectively disperse diluted or concentrated formulations into open air. Systems are available with oscillators ensuring even product distribution.
Applications: Primary applications include enclosed areas up to 300 m², with series installations covering larger spaces. Systems have been successfully deployed in wet wells and sewage treatment stations. Popularity has grown due to system simplicity and reliability.
4.4 Vapor Phase Systems
True vapor phase odour control systems provide simple, effective methods for transforming products into vapor states easily transmitted into malodorous environments. Systems vaporize products for maximum utilization without requiring large water volumes. This is critically important where added moisture and humidity are unacceptable.
System Advantages:
- Minimal moisture addition
- Higher absorption efficiency through smaller droplet sizes
- No water dilution required on-site
- Flexible and efficient distribution
- Flow rates from 3,700 to 68,000 m³/hr
- Simple operation and maintenance
Design Considerations: Vapor phase systems work best where:
- Odour sources are localized or easily isolated
- Moisture addition must be minimized
- High-efficiency droplet delivery is required
- Water supply limitations exist
- Simplified operation is preferred
4.5 Traditional Chemical Scrubbers with Anotec Products
Anotec’s formulations can replace various hazardous odour control chemicals in traditional scrubbing systems, offering environmentally friendly substitutes for dangerous chemicals currently used in many scrubber installations.
Important Considerations: Prior investigation of odour control regulations and requirements may save substantial capital costs by avoiding costly scrubber installations. Simple injection or fogging processes using Anotec’s plant-based formulations may allow facilities to meet or exceed local odour emission regulations while saving extensive costs.
Design Considerations for Scrubber Integration: When integrating Anotec’s formulations into scrubbing systems, consider:
- Liquid flow rates and residence times
- Gas flow rates and velocities
- Contact efficiency between gas and liquid phases
- pH management and buffering capacity
- Recirculation rates and blowdown requirements
- Material compatibility with scrubber construction

4.8 Dosage Rate Optimization
The quantity of Anotec’s plant-based formulation required for odour control depends on malodour source volume and intensity. Correct application and dilution rates create atmospheres where neither malodours nor product scents are noticeable.
Equilibrium Point Concept: Increasing product consumption directly relates to malodour sensitivity reduction. Once the equilibrium point of “neutral odour” is reached, increasing product use results in a product scent within the surrounding atmosphere. Many clients lose perception that odour problems exist or products are working effectively once neutral points are reached.
Determining Optimal Rates: Most effective application and dilution rates for Anotec’s plant-based products must be determined on-site. Malodour levels present determine required product levels. Determining factors include:
- Odour composition and chemical nature
- Delivery system efficiency
- Airflow rates and patterns
- Probability of contact between droplets and odour molecules
- Contact time and reaction time
- Atmospheric conditions (temperature, humidity, pressure)
