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.

EXISTING LAGOONS
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.

NEW LAGOON SYSTEMS
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.

Practical Clearwell Solutions

Retention time problems can be solved in an easy, cost efficient manner by using the new system by ThermaFab. The Bio-Separator Clearwell system offers value over the costly, traditional fixed wall baffles, while providing the same superior performance. The resulting increased retention time provides enhanced disinfection in the final treatment phase.

Bio-Separator Clearwell baffles are custom designed for each facility to provide maximum strength and durability. Using only stainless steel hardware, the vertical position of each baffle curtain is maintained by a structural design created by either the project engineer or ThermaFab technical staff. To ensure safety and reliability, all Bio-Separator Clearwell baffles are fabricated from reinforced geomembrane materials. Tested to withstand chlorine, extreme temperatures, rips, abrasion, and hydraulic shock, all fabrics are FDA or NSF approved. ThermaFab's one-year warranty demonstrates its confidence in the materials and workmanship of its Clearwell baffles.

Installation of the Bio-Separator Clearwell baffles is a quick and simple process. Requiring only a temporary drain of the tank, ThermaFab will provide either an installation team or a certified field technician to supervise the operation. However, in cases when it is impossible to take the clearwell out of service, installation of the ThermaFab system may be performed by a diving team. Once in place, the benefits of the Bio-Separator Clearwell baffles are immediately realized.
