BIO-CLEAR Packaged Treatment Plant

The Bio-Clear packaged sewage treatment system is designed for developments like hospitals, hotels, and rural communities that are required to treat wastewater to levels suitable for discharge. The multi-stage treatment process includes screening, diffused aeration, clarification, sludge recirculation, sludge digestion, filtration, and disinfection. Pre-engineered modular components such as diffused air blowers, aeration tanks, sludge holding tanks, clarifiers, and disinfection units allow for the package plants to be sized specifically for the customer’s application. Systems are designed to handle a range of influent flows and consistently reduce TSS and BOD to <20mg/L.

How it Works

Wastewater enters the package plant first passing through a bar screen for large solids removal. In the equalization tank water is retained to create a homogenous mixture prior to treatment. Upon entry into the aeration basin, water is mixed with an active biomass in a rolling action which takes place over the length and width of the chamber. The chambers are filleted on each side and the bottom to enhance the rolling motion and eliminate any “dead zones” in the tank. This design feature also minimizes the accumulation of scum and froth in the aeration tank.

After sufficient contact time in the aeration chamber, water flows into the clarifier and solids settle in the hopper-bottom tank. Solids are recirculated through the system or withdrawn as needed. Clean water flows through the clarifier into the clearwell where it is re-pressurized and passed through the tertiary filters and disinfection systems.

Design Flow Guidelines

Information on flow rate is necessary for the design of an effective wastewater treatment and disposal system. The wastewater flow rates of existing facilities can often be measured. The below table can be used as a basis for the design of sewage treatment and disposal facilities for new developments, and for existing establishments when the hydraulic loading cannot be measured. Alternatively, water-usage data can be used to estimate wastewater flow, if it is available for an establishment. Adjustments should be made for infiltration, and for water that will not reach the sewer (e.g. boiler water).
