BOD5 REMOVALS VIA BIOLOGICAL CONTACT AND BALLASTED CLARIFICATION FOR WET WEATHER
Ballasted clarification has long been accepted as a viable treatment method for the removal of solids (TSS) from wet weather wastewater flows. However, as there is no biological mechanism in a typical system, removal of Soluble BOD5 is minimal and total BOD5 removal is therefore a function of the Total BOD5 present as particulate. The addition of an aerated contact tank upstream of the ballasted clarification unit, where wet weather wastewater and Return Activated Sludge (RAS) are combined, has been proposed as a means to accomplish Soluble BOD5 (SBOD5) uptake and meet the EPA's requirement of 85% Total BOD5 removal for secondary treatment.
SUSTAINABILITY AND TMDL COMPLIANCE USING INTEGRATED FIXED FILM ACTIVATED SLUDGE (IFAS) PROCESS IN COCOA BEACH, FL
The AnoxKaldnes Hybas™ process achieved sustainability and efficiency for Cocoa Beach. Upon project completion, the plant saw a decrease in: nutrient mass, sludge residuals and unit energy conservation. Data has been compiled documenting the reduction for all three parameters.
