Air Filtration Solutions for Wastewater Treatment Facilities

Wastewater treatment is the process of improving the quality of wastewater and allowing human and industrial effluents to be disposed of without affecting human health or incurring unacceptable damage to the natural environment.

Major sources of industrial effluents

• Agricultural Industry
• Dairy Industry
• Pulp & Paper Industry
• Metal Industries
• Mining Industry
• Food & Beverage Industry
• Chemicals, Petrochemicals, and Refineries
• Nuclear Industry

Several kinds of wastewater are treated at the appropriate type of wastewater treatment plant.

Types of wastewater treatment plants:

• Sewage treatment plants
• Industrial wastewater treatment plants
• Agricultural wastewater treatment plants
• Leachate treatment plants

There are two main levels of wastewater treatment: primary and secondary treatment.

In the primary stage, solids are permitted to settle and be removed from wastewater. The secondary stage uses biological processes to further purify wastewater.

Industrial wastewater treatment generates odors that can be strong, persistent, and a nuisance to employees, residents, businesses, and industries located near the wastewater treatment plant. Strong odors develop at several areas within a wastewater treatment facility, such as headworks, primary clarifiers, pump stations, and sewage sludge areas.

Nuisance odors often emerge from the following sources:
• Combined sewer overflow (BTEX, TCE, and other VOCs)
• Industrial sewage (benzene, industrial chemical effluents such as amines, and other VOCs)
• Residential sewage (ammonia, hydrogen sulfide, and mercaptans)

Not only is hydrogen sulfide potentially dangerous at high concentrations, but electronic corrosion at these plants can occur when corrosive, acidic gases attack sensitive computer controls and other critical electronics that affect the reliability of plant processes. Both the neighboring community and treatment plant employees will benefit from a properly implemented odour control solution.

Another significant common issue that is found at wastewater treatment plants is electronic corrosion. Electronic corrosion at these plants can occur when corrosive, acidic gases attack sensitive computer controls and other critical electronics that affect the reliability of plant processes.

Corrosion is a complex series of reactions between the water and metal surfaces (metal piping) and materials in which the water is stored or transported. The corrosion process is an oxidation/reduction reaction that results in the refined or processed metal being changed to their more stable state.

With respect to the corrosion potential of drinking water, the primary concerns include the potential presence of toxic metals, such as aluminum, copper, nickel, lead, and zinc; deterioration and damage to the household plumbing; and aesthetic problems such as stained laundry, bitter taste, and greenish-blue stains around basins and drains.

If not controlled, corrosion leads to:
• Blocked currents
• Brittle connection points
• Overheated systems
• Costly repairs
• Failed boards
• Plant downtime
• Reduced production efficiency in compressed air systems and increased maintenance costs

We at American Air Filter (AAF) specialize in the elimination of malodorous gases; protection of electronics from corrosion and particulates to prevent failures and downtime, and protection of air compressors from corrosion and particulates to ensure proper functioning.

Optimize Your Filtration and Improve Your Environment

The solution to these issues starts with a thorough air filter audit of your HVAC Systems by AAF. This collaborative and consultative solutions approach is undertaken to understand your complete air filtration needs, applications, and goals for total air quality.

This customized air filtration survey costs you nothing and could give you significant benefits by helping you save money, reduce risk, and save time.

Contact your AAF representative to schedule an audit and to find out how the insights from intelligent data tools, including TCO Diagnostic® and Sensor 360®, can improve your operational outcomes.
