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.

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.

Aqua-Aerobic® Membrane Systems featuring NO BREAK Aqua MultiBore® membranes are designed to effectively remove suspended solids, particulate phosphorus, bacteria, cysts and other harmful impurities, resulting in safe, high quality water

  • A phase-activated sludge system (PASS) reduces energy consumption by combining the aerobic and anoxic tanks and alternating diffusers between the on and off position based on a preprogrammed schedule.

  • Pile cloth media filters are a cost-effective and simple solution to prevent microplastics from entering water systems through industrial effluent and municipal wastewater.

  • Conventional activated sludge treatment for wastewater is becoming increasingly problematic over time. Not only does the process require significant amounts of energy, which drives up operating expenses, but utilities are under mounting pressure from the U.S. EPA to go green.

  • Pile cloth media filtration technology has been around for decades, used mainly for tertiary wastewater treatment — a final stage of the treatment process — to filter effluent before it leaves the plant. However, the technology is now poised to provide extensive benefits as an advanced primary treatment technology. It stacks up well against other methods, which include chemically enhanced solutions that present additional operating costs and ultrafine screens that remove fewer solids.

  • The Moab Water Reclamation Facility (WRF) was initially constructed in the late 1950’s to provide primary treatment of domestic wastewater for the Moab area. However, the plant could no longer keep up with the higher flows and loading due to population growth and rising tourism. In addition, with aging infrastructure and the new permit cycle in sight, upgrades to the biological treatment were necessary to ensure full compliance. Read the full case study to learn more.

  • Both direct and indirect potable reuse have massive potential to address growing water scarcity issues. However, the total cost of ownership can present a significant challenge to getting reuse projects off the ground. The good news is that another solution now provides a comparable option for reuse that is often superior to common reuse treatment trains currently in operation.

  • The AquaNereda® Aerobic Granular Sludge (AGS) Technology is an innovative biological wastewater treatment technology that provides advanced treatment using the unique features of aerobic granular biomass. An aerobic granular biomass is comprised of compact granules that provide advantages compared to other secondary treatment processes.

  • The Abbottstown-Paradise Joint Sewer Authority was incorporated in 1973 and utilized a continuous flow activated sludge system with an average daily design flow of 0.21 MGD. At that time the plant was only required to reduce total suspended solids (TSS) and effuent ammonia to required levels to serve the area population of about 2000. Due to urban growth and increased storm flow runoffs, the plant was in need of an expansion and upgrade by the late 1990s. 

  • With the current national emphasis on restoring the water quality of America’s urban waterways, the City of Brockton, Massachusetts, Advanced Water Reclamation Facility (AWRF) wanted to stay ahead of the regulatory cycle – in particular, phosphorus discharge limits set forth by the National Pollution Discharge Elimination System (NPDES) program of the United States Environmental Protection Agency (U.S. EPA). For this region of the country, the U.S. EPA has proposed total phosphorus (TP) discharge limits of 0.1 mg/L.
