Bio Clear Biological Treatment Process

System Overview

The Bio-Clear is a pre-engineered, prefabricated system for treating domestic wastewater with an aerobic process. Systems are typically sized according to flow rate, and often require a fraction of the space needed by conventional biological treatment systems. Our modular approach with this system provides the user with a compact, easy to operate, and cost effective solution. This packaged system has an exceptional track record as an efficient method of wastewater treatment.

Bio-Clear Biological Treatment System

System Overview

The Bio-Clear packaged wastewater treatment system utilizes an extended aeration principal of operation which is a variation of the activated sludge process. This system functions by creating an environment with sufficient oxygen levels and agitation to allow for bio-oxidation of the wastes to suitable levels for discharge. The packaged wastewater treatment system utilizes a multi-step treatment process to achieve the desired final discharge requirements. The treatment systems consist of comminution, screening, diffused aeration, clarification, sludge recirculation, sludge digestion, disinfection, and filtration. 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. They can be designed to handle a variety of influent flows and BOD loadings, as well as meet a myriad of mandated discharge parameters.

The influent wastewater enters the package plant by passing through a comminutor and bar screen for gross solids removal. This step provides for the mechanical reduction of solids prior to aeration. Once the wastewater has entered the aeration chamber, the untreated flow is mixed with an active biomass in a rolling action which takes place the length and width of the chamber in a slow forward progression. This rolling mixing action is the result of air originating from diffusers located along one side of the wall and bottom of the tank. This insures that adequate mixing is maintained in the tank. The chambers are filleted on each side and the bottom to assure and enhance the rolling motion of the water and eliminates any "dead zones" in the tank. This design feature also minimizes the accumulation of scum and froth in the aeration tank. The oxygen transfer achieved with the diffused air passing through the wastewater coupled with the rolling action provides a sufficient oxygen supply to allow microorganisms to oxidize treatable wastewater into carbon dioxide, water, and a stable sludge.
