Activated Carbon Adsorption System
The Activated Carbon Adsorption System is a highly effective odour control technology that
operates on the principle of adsorption. This process captures odorous gas molecules on the surface of
activated carbon media, where they are oxidized and transformed into odourless gases, which are then safely
released into the atmosphere. The selection of activated carbon media depends on the specific odours to be
treated. For wastewater odour removal, specialized filtration media are chosen to target gases like
Hydrogen Sulphide, Ammonia, VOCs, and Mercaptans. .
A variety of adsorption media are available for odour control applications, including virgin
activated
carbon, chemically impregnated carbon, and catalytic activated carbon. For wastewater odours,
water-regenerable catalytic activated carbon is often preferred due to its long-lasting
performance,
in-place cleaning capability, and environmental friendliness, as it does not require additional chemicals
for maintenance. A well-designed activated carbon adsorption system can consistently achieve odour removal
efficiencies of 99.9% or higher

ventilation to allow odour removal without requiring electricity or active operational attention.
Odovent MX uses advanced filtration media specially selected for its high capacity to adsorb odorous gases.
This media is capable of removing over 99.9% of odours, ensuring a fresh and clean environment in
residential and urban areas impacted by sewage emissions. The unit is designed with durability in mind,
constructed from corrosion-resistant materials such as UV-protected polypropylene (PP) or fiber-reinforced
plastic (FRP), which ensures a long operational life even in harsh outdoor conditions. Standard units can
handle an airflow rates upto 100 m3/hr.
Passive Odour Control Unit
The AQOZA Passive Odour Control Unit is an effective solution for small lifting stations and manholes where
odour removal occurs through natural ventilation, influenced by water level changes in the system. This unit
is designed for ease of use and requires no external power or water supply, making it particularly suited
for remote and hard-to-access locations. With its straightforward design, the Passive Odour Control Unit can
handle airflow rates from 100 m³/hr to 600 m³/hr, providing efficient odour control in smaller, less complex
facilities. Its passive operation ensures minimal maintenance, making it a cost-effective solution for
managing odour without needing constant supervision. This unit is ideal for locations where active systems
may not be practical, offering a reliable and eco-friendly option for maintaining air quality in municipal
and industrial settings.
Active Odour Control Unit
AQOZA’s Active Odour Control Unit is a highly efficient, compact system designed for small
lifting
stations, collection tanks, and wastewater treatment plants. This unit actively removes odorous gases using
a built-in extraction fan, which continuously draws odour-laden air from the source, maintaining low gas
concentrations in the tank and ensuring odours are reduced to undetectable levels. The Active Odour Control
Unit is user-friendly, requiring only minimal operator attention and can be operated by in-house treatment
plant staff. With odour removal efficiencies of 99.9% or higher, this unit is exceptionally
effective in
creating a safe and pleasant environment. Standard capacities range from 250 m³/hr to 2,500
m³/hr airflow,
making it suitable for various industrial and municipal applications. AQOZA’s Active Odour Control Unit is
an excellent choice for facilities seeking a robust and dependable odour management solution.

Here’s an optimized version for both the Biological Oxidation Odour Control System and the
Combination of
Biological & Activated Carbon System:
Biological Oxidation Odour Control System
With extensive industry knowledge and field experience, AQOZA has developed eco-friendly, highly efficient
solutions for odour control applications. Our Biological Oxidation Odour Control System effectively targets
odorous gases such as hydrogen sulfide, mercaptans, and VOCs, which are common in wastewater treatment
facilities.
AQOZA Bio-Scrubber
The AQOZA Bio-Scrubber operates on the principles of absorption and biological oxidation,
where
microorganisms break down odorous compounds into harmless byproducts. The Bio-Scrubber is filled with highly
porous inorganic media, optimized to support microbial growth and maximize the contact time between polluted
air and microorganisms. A nutrient-rich water solution is recirculated continuously and sprayed over the
media, keeping the system moist and maintaining optimal pH levels for microbial activity.
This design allows the Bio-Scrubber to consistently achieve odour removal efficiencies of up to
99% when
managed within the required contact time and operational parameters. The system is fully automated,
featuring a PLC-based control system that continuously monitors and adjusts operating
conditions using
integrated sensors. This automation reduces the need for operator intervention and significantly lowers
recurring costs compared to conventional chemical scrubbers. AQOZA's Bio-Scrubber offers a sustainable,
low-maintenance solution that enhances air quality in wastewater facilities.
Combination of Biological & Activated Carbon System
For applications requiring exceptionally high odour removal efficiency, AQOZA offers a dual-stage odour
control system combining a Bio-Scrubber with an Activated Carbon Adsorption Unit. This hybrid approach is
ideal for municipalities and industries seeking reliable, high-performance odour control solutions. In this
setup, the Bio-Scrubber serves as the first stage, where it removes the bulk of odorous gases through
biological oxidation. The air then passes through an activated carbon adsorption unit, which polishes the
air and captures any remaining odour molecules
This combination achieves an odour removal efficiency of up to 99.99% or higher, ensuring compliance with
strict air quality standards. Additionally, the dual-stage setup reduces operational costs by extending the
lifespan of the activated carbon media, as the Bio-Scrubber handles most of the odour removal load. In the
rare event of a Bio-Scrubber malfunction, the activated carbon stage provides a backup, ensuring continuous
high-efficiency odour control.
AQOZA’s combination systems are ideal for wastewater treatment facilities, lifting stations, and other
industrial applications where superior odour control is essential. By integrating biological and adsorption
technologies, AQOZA provides a dependable, cost-effective solution for maintaining a safe, odour-free
environment.
