Hydro-Action Industries Aerobic Onsite Wastewater Treatment. Tested and Standard (Class I) Certified 40 by ANSI/NSF.

Good Ideas Are in The Air

Meet the AP-500 Aerobic Treatment Unit (ATU), the heart of our wastewater management system. It learned to clean wastewater from the best teacher around: Mother Nature herself. Just as waste breaks down organically from air, the aerobic bacterial action in our ATU uses oxygen to treat wastewater. 

The Break Down—Naturally

The Hydro-Action system outperforms traditional septic tanks in prolonging drain field life, meeting environmental requirements, and handling issues like poor soil or high groundwater.

How it works:

The Hydro-Action ATU Prepares Wastewater. 
Before wastewater enters the ATU, it runs through the pretreatment or septic tank. Pretreating reduces the amount of solids and other materials that can get into the system. The system’s flexibility allows the ATU to be added to an existing septic tank or used with the Hydro-Action system alone.

Processes Effluent
When effluent arrives from the pretreatment/septic tank, the ATU gets to work. The Aeration Compartment is why the ATU blows traditional septic tank technology right out of the water. A pump injects air into the system, pushing it down Flexible Air Lines and through the Anchored Diffuser Assemblies (patent pending) to the compartment, where oxygenation begins. There, aerobic bacteria are force fed oxygen and multiply, cleaning the wastewater without chemicals and filters.

Creates Clear, Odorless Effluent
Oxygenated effluent then enters ATU’s Clarification Compartment, a conically- shaped area that separates clarified water from any remaining solids, which settle and return for further aeration. Effluent arrives and leaves the Clarification Compartment by hydraulic action, and from there it enters the dosing tank, field or mound disposal system—without any worries about bio-matting. 
With wastewater management, prevention counts. Our OPS®, or Operations control center, alerts the user through visual and audio signals if the system becomes too full or air pressure drops to unacceptable levels, so a certified installer can be contacted for maintenance.

Laying The Groundwork For Installation

Our Set-N-Go® Installation Package, the most complete Class I treatment system available today, includes everything an installer needs—the ATU as well as pretreatment and dosing tanks, with all supporting parts. 

Every factory-assembled package is thoroughly tested for quick onsite installation and accurate operation. For example, we make sure installers won’t struggle with multiple depth levels that require custom, time-consuming digging—Set-N-Go® uses a smaller hole, giving you a safer, faster, more reliable installation.

We have a process and product that work. With thousands of installed units working for customers, and over 30 years experience in wastewater management, we’re proven professionals.

Hydro-Action: Down To Earth Savings 

No one can afford failing wastewater systems. The superior efficiency of our products offers the best wastewater solutions for residential and commercial applications.

Hydro-Action is revolutionizing wastewater management with practical, green solutions that acknowledge our limited environmental resources. With smart, fast-performing, aerobic technology, we treat water the same way nature does. The only resource we don’t see as limited?—Our Quality.
