Bio Separator

A Floating Division Baffle

The basic goals in designing the bio-separator were to provide an economical and effective method for designing new lagoon systems, and upgrading existing lagoon systems to accept increased flows, as well as increasing the performance to meet treatment limits within the EPA guidelines.

The Bio-Separator is a pre-engineered, custom fabricated, flow diverting baffle which can be manufactured using a variety of fabric reinforced coated materials. The material selection is based on the application and the chemical make-up of the waste to be treated.

The Bio-Separator is fabricated to the specific length, depth, and side slope desired. Windows can be positioned to achieve the desired flow pattern in the lagoon.

The use of the Bio-Separator offers an economical approach for the upgrade of existing lagoon systems to meet the allowable limits for BODs and Total Suspended Solids imposed by the United States Environmental Protection Agency. The floating baffles allow the system to be upgraded without the expense and difficulty of dewatering the lagoon, which is usually required when earthen dikes or rigid baffle systems are used.
Lagoon systems using the floating baffles provide a low cost alternative to activated sludge systems. Properly designed, these systems can produce effluents in which the average concentration for BODs and Total Suspended Solids meet the requirement set by the EPA. Other attractive features are that these systems require very little maintenance or operator attention, can be constructed at a cost which is 40 to 50 % less than activated sludge systems, and operate at a power level 50% less than activated sludge plants.

Industrial lagoons: The Bio-Separator can be designed and fabricated to meet the specific needs of an industrial waste treatment process. Based on bench scale treatability studies, a fabric resistant to the waste can be selected. A curtain can be used to create mixing areas, activated sludge basins, clarification areas with positive sludge return, and disinfection areas.
