Wastewater Treatment Odor Control

Eliminate odors, reduce complaints at wastewater facilities.

Controlling wastewater odors is one of the most challenging aspects of its treatment. Bad smells from treatment plants cause complaints from nearby communities and parks. Odors also wear on plant workers, decreasing their job satisfaction and lowering retention rates. Left uncontrolled, odor issues can bring negative attention and damage the reputation of wastewater plants.

Not all wastewater treatment odors are created equal. Common lingering odors include rotten eggs, ammonia, garlic, or earthly smells are caused by hydrogen sulfide (H2S), amines, sulfur dioxide, skatoles, indoles, and mercaptans. Because of the diverse range of smells and odor sources, a variety of control methods are often needed for complete odor removal.

Each plant has its own unique problem areas, all which can be solved with Ecosorb® odor control products.

Benefits of Ecosorb

Natural

Ecosorb uses the natural power of plant oils to remove odors from wastewater treatment.

Safe

Non-toxic, non-hazardous, biodegradable, non-flammable, and no harmful VOCs.

Effective

Proven and trusted by wastewater facilities nationwide.

Complete

Custom formulations for pump stations, head works, clarifiers, digesters, aeration basins, lagoons and sludge handling areas.

Headworks and Primary Treatment

Hydrogen sulfide odor is a serious issue in wastewater treatment plants. Vapor or fan systems installed at the bar screens and digesters solve the problem. In some cases Ecosorb odor control products can be diluted with plant water for more cost-effective operations.

Wastewater Septage Dumping

Raw septage from haulers can present odor problems to plants that otherwise have their industrial emissions under control. Fan or nozzle atomization systems posted near the unloading point and vented or open downstream locations provide effective odor removal.

Activated Sludge Basins

Because basins for activated sludge can be large and uncovered, smells are free to drift into nearby areas. Our experienced engineers develop custom Ecosorb delivery systems to neutralize odors and prevent them from affecting neighbors.

Food Processing Plants

Many food processing facilities have their own wastewater treatment plants. Controlling odors becomes two-fold: smells generated from processed food and from wastewater lagoons. Ecosorb odor neutralization products are approved for use outside of food processing plants and are safe for the environment.

How to Use

Whenever possible, we use existing odor control hardware (e.g. scrubbers) to apply Ecosorb odor control solutions. In situations where there is no current system in place to control odors, our team designs system options.

Most facilities opt for vaporization systems, where ducting carries Ecosorb product in submicron form to the source of the odor, neutralizing it on contact. There are no nozzles to plug making this system virtually maintenance free.

Many systems are operated on an “as needed” basis, and switched on when the odor reaches a certain perceived level, while others kick on automatically based on wind direction, when air currents cause odors to travel toward neighboring businesses or residential developments.
