The AquaStorm™ cloth media filtration system is designed as an economical and efficient solution for the treatment of wet weather applications. This system utilizes a disk configuration and the exclusive OptiFiber PF-14® pile cloth filtration media to effectively filter high solids waste streams with and without the use of chemicals as determined necessary for application-specific water quality. This system is ideal for wet weather applications due to its proven removal efficiencies and high quality effluent, even under varying influent conditions.

The AquaNereda® Aerobic Granular Sludge System is an innovative biological wastewater treatment technology that provides advanced treatment using the unique features of aerobic granular biomass. The unique process features of the AquaNereda system translate into a flexible and compact process that offers energy efficiency and significantly lower chemical consumption.

The Aqua-Jet® SS-PW surface mechanical aerator, manufactured by Aqua-Aerobic Systems is certified to NSF/ANSI 61 by UL for use in potable water applications. These units can be utilized for THM stripping applications or circulation in potable water treatment systems and reservoirs with a minimum volume of 100,000 gallons.

The AquaPrime system utilizes a disk configuration and the exclusive OptiFiber® cloth filtration media to effectively filter screened, de-gritted, raw municipal sewage. This proven technology easily handles significantly higher solids loading rates compared to secondary clarified effluent (by a factor of 3 to 5 times) with the added ability to sustain a low TSS concentration, making it an ideal solution for both wet weather treatment and primary treatment in lieu of conventional sedimentation systems.

Ozone treatment for water and wastewater has been utilized successfully for several decades and continues to be a viable disinfection solution for both municipal and industrial plants, worldwide.

Technology pilot demonstrations can be beneficial to wastewater treatment plants by providing a snapshot of essential process operating conditions and allowing the customer to interact with the technology and factory personnel.

The Aqua MegaDisk cloth media filter expands on the reliability and exceptional performance of the original AquaDisk filter on a larger scale.

OptiFiber PES-14® Microfiber cloth filtration media is engineered to remove suspended solids, turbidity and fine particles up to 50% better than other filters or microscreens. Microfiber cloth media is proven to reduce total phosphorus to 0.1 mg/l or less.
