The Hydro-Action Standard 245 system is built around the Hydro-Action® AN Series individual wastewater treatment plant. This is a self-contained, extended aeration, aerobic treatment facility utilizing the combination of the activated sludge process and wastewater recirculation for denitrification. This two tank ATU is rated for 440, 550, 660, 800, and 1100 gallons per day. The AN Series was created to meet more stringent needs in Nitrogen Reduction for sensitive land issues and enhanced nutrient removal. The Hydro-Action Standard 245 meets the NSF/ANSI 245 set by the National Sanitation Foundation, a testing authority in wastewater treatment.
Wastewater enters the system and flows into the primary settling and anoxic tank, where anaerobic bacteria break down nitrates to reduce nitrogen. The water then moves to the aeration compartment, where oxygen is injected to support aerobic bacteria that break down waste. Finally, the water enters the clarification compartment, where solids settle and are recirculated, producing clear, odorless effluent ready for disposal. The system’s recirculation process ensures enhanced nitrogen removal.
This warranty exceeds the NSF requirement of two (2) years.
Vacuum-tested fiberglass design, manufactured by a U.S. industry leader with over 35 years of experience.
Fiberglass is lighter than concrete, and our tanks can be nested for transit, making delivery easier.
Simple installation, higher adaptability to land conditions, and economical operation.
Easily installed without heavy equipment and fast and hassle-free maintenance.
We train and certify our distributors to be experts in the field of aerobic wastewater treatment.
Locate the OPS remotely and can be installed as a supplemental unit to existing systems.
Aerobic action instead of chemicals, higher-quality effluent, and flexibility for sensitive land areas.
The plant consists of an engineered pre-treatment septic tank and a cylindrically shaped aeration tank with an offset service access, a unique cone-shaped clarification compartment and an outlet tee-assembly. Three fine-bubble air diffuser assemblies with hard pipe diffusers and Hydro-Action® efficient air pump are combined to provide effective, efficient, and economical aeration.
The AN Series ATUs are operated by the OPS®. The OPS® integrates the electrical controls, visible and audible alarms and air pump in a protective polyethylene enclosure. The OPS® can be either platform mounted on the plant or remotely located. These features plus the offset access, airline piping, and diffuser assemblies make the plant extremely reliable and easy to service. The visible and audible alarm may be added to remotely locate to an area of your choice.

*The technology used in the Hydro-Action® plant allows it to produce excellent effluent quality, which thereby meets all ANSI\NSF International Standard 40 & 245 class I and the Environmental Protection Agency’s requirements of a secondary treatment process and Nitrogen reduction. NSF requires that a Class I plant shall be shown to meet EPA secondary treatment guidelines for CBOD5, TSS, and ph. The Hydro-Action® AN Series ATUs satisfy all these requirements. It also surpasses state-determined field verified testing of Total Nitrogen Effluent levels in Maryland and New York.
