Our Extended Aeration Process Systems are prefabricated factory-built units complete and ready for easy installation at your project site. Applications are to meet secondary treatment effluent limits from domestic wastewater from higher flow systems and most suitable when treated effluent is going to be discharged into receiving waters. Available for design flow rates up to 500K GPD, the purpose of this secondary treatment process is to reduce influent wastewater flow by 90% through oxidation of the BOD5 and suspended solids . Features include a compact design, automatic air control system, quality components ideal for retro-fitting, ease of installation, and simple operation. Optional features include tertiary filtration thru a Rapid Sand Process to meet higher effluent standards as required by the local permitting authorities.

The Biotank is a uniquely flexible system, offering a wide scope of direct applications for flows ranges up to 1,000,000 gpd. It utilizes a fixed-film process in which microorganisms attach themselves to a high specific surface area media that is submerged in wastewater. This allows the absorption of organic as well as inorganic matter into the bio-film layer where treatment is realized. This membrane bioreactor system can be utilized in a variety of applications including residential, commercial, municipal and Industrial. Marked advantages of this system design are:

• No surplus sludge
• Low capital cost
• Smallest footprint of available technology
• No odor or noise
• High process stability
• Easy operation & maintenance
• Low energy consumption
• Simple installation
• Modular build

The BioTank suspended growth biological treatment is accomplished using a community of microorganisms that metabolize the dissolved colloidal carbonaceous organic matter into gases or cell tissues that is removed from the water by gravity separation. Utilizing the latest in flat sheet microfiltration membranes, the Biotank exhibits COD removal rates that are as good as or better than those observed by conventional suspended growth reactors. Enhanced performance provides for a reduction of total nitrogen, total phosphorous and organic suspensions. The BioTank is ideal for municipal sewage treatment and offers several benefits over activated sludge process. These benefits include:

• Smaller space requirements
• Better solids removal
• Pathogen reduction
• Lower sludge production

Aqua Tech Systems offers this patented process which presents a new breakthrough in biological wastewater treatment. This innovative pre-engineered system has the capability of eliminating routine sludge handling. The minimal solids produced go out with the effluent while BOD/TSS levels never exceed effluent limits. This reduces the need for extensive plant operations/calculations which translates into cost savings for municipalities or private utilities. The optimization of bacteria within the engineered systems maximizes the efficiency of the biological process. No odors arise because the dissolved oxygen concentration is close to its maximum level. The process is most suited for designed systems of 40K GPD and higher where the treated effluent can be disbursed into a subsurface drip irrigation system.

This reliable and proven process can be used in a variety of applications including commercial, community and municipal applications. The simple and efficient wastewater treatment process of this treatment unit is most suited for flows below 40K GPD. The process relies on the principle of bacterial segregation, a phenomenon that allows excellent performance results, reducing BOD, TSS and fats, oils and grease (FOG) to within regulatory standards. It has many marked advantages making it an ideal choice for many reasons:

• Preassembled for quick installation
• Modular for multi-phased development
• Superior performance in peak flows, effluent quality and temperature variations
• Minimal Footprint Needed
• Low Energy and Maintenance Costs
• Quick and East Operations and Maintenance
