Tank covers
Defender™ Tank Covers from Environetics are less expensive than fiberglass or aluminum and are custom-built to fit existing tanks. The attractive low-profile design minimizes internal volume and reduces treatment system requirements, and a mechanical attachment system provides a positive seal for odor containment. They feature clear-span structural aluminum frames that provide strength, and the durable reinforced geomembrane material reduces the cost. Further, hinged hatches allow easy access, and modular construction enables rapid installation. The opaque geomembrane cover material also prevents ultraviolet light from entering the tank, prohibiting algae growth.

Odor control
Unlike other systems that extract and treat odors, the Terminodour system from Kusters Water is unique in that it oxides the odor at the point of the source. The ionized air is distributed into the building where it reacts and oxides odors while maintaining a healthy working environment for operators and reducing corrosion. Terminodour uses no water, chemical or media, which minimizes capital and operational costs in dealing with spent media or consumables.

Ozone generators
The Primozone® GM1, GM2 and GM3 are the first truly robust ozone generators designed for smaller ozone needs. Based on the Primozone ozone technology used in the larger units, these compact units are downsized without compromising quality, efficiency or safety. With its very small footprint, modular design and high ozone concentration, the generators are ideal for wastewater odor control at lift stations.

Cover systems
Any wastewater treatment process has the potential to generate and release nuisance odors, especially when tanks are left uncovered. Geomembrane Technologies (GTI) provides retractable, structurally supported cover systems for effective odor control for wastewater treatment plants worldwide. GTI's structurally supported covers are designed to: reliably capture odorous off-gases; disconnect and retract easily for inspection and maintenance of tank internals; block sunlight to control algae growth; reduce chlorine loss and disinfectant byproduct production; and prevent rainwater and debris from entering tanks. GTI's covers are custom designed and can be installed without disrupting plant operation.

Biological odor control
The OdorCap 5700 from Novozymes Biologicals contains patented biological wastewater odor control technology and can degrade hydrogen sulfide, mercaptans and volatile fatty acids. A biological wastewater odor control program using Novozyme's system offers superior odor prevention because it works in the same environments where odors are generated. Further, it has no unintended negative impact on the biological treatment system. The OdorCap 5700 works within existing plant infrastructure.

Dual-tech filter
EcoPure® from BioAir delivers a double-barreled odor control solution: a proprietary biotrickling filtering system and patent-pending EcoBase® media technology, combined with an EcoSorb polishing step, providing very low emissions. By combining activated carbon with the air purification power of the EcoFilter® biotrickling filter, the carbon life is extended by up to 10 times over that of typical carbon filters. With this product, two-stage odor control is no longer only suitable for pump stations. EcoPure delivers the same reliability and performance for larger applications, and a single unit can treat air streams from 100 to 7,000 cfm.

Odor neutralizers
For controlling all odors common to municipal and industrial wastewater treatment plants, collection systems and processing, Ecosorb® odor control solutions offer a non-toxic biodegradable option for completely removing malodors. Natural Ecosorb odor control products can be delivered via methods including atomization and vapor phase, using existing hardware (e.g., scrubbers) or a custom solution designed to suit specific needs. The new vaporizing dispersion systems now include PLC controls, which can be operated from a PC or phone.

Filtration media
WaterKlean™ Water Treatment Filtration Media was specially developed to absorb and encapsulate many unpleasant odors found in wastewater and effluent streams such as mercaptans, formaldehyde, ammonia, sulfur dioxide, nitrogen dioxide, hydrogen sulfide, VOCs, and many more. Further, the system will also remove a wide range of heavy metal and other cations via ion exchange. WaterKlean is non-toxic, safe, reusable-recyclable, natural, odorless, non-flammable, and non-caustic. It is an ideal solution for absorbing odors and removing heavy metals without adding pollutants to the environment. It does not contain VOCs, harmful or ozone-depleting chemicals or fossil fuels.
