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.

NEOSEP® MBR: An Operator's Best Friend

Membrane modules should be easy to install, easy to retrieve when necessary and simple to maintain. These fundamental necessities of a Membrane Bioreactor (MBR) system are at the heart of the K-120C and K-240C flat sheet membrane modules provided by Kruger, a subsidiary of Veolia.

Deammonification Process Brings Carbon, Energy, and Sludge Reductions

Over the past decade and a half, a growing number of U.S. utilities have found that moving bed biofilm technology provides an effective alternative for expanding or improving wastewater treatment. Because of their small footprint, moving bed bioreactors (MBBR) and integrated fixed film activated sludge (IFAS) represent especially attractive options. This is particularly true for site-constrained facilities or those wanting to retrofit existing tankage.

Membrane Technologies: A Clear Choice For Water Reuse

Population growth, decreasing supply volumes and quality, and droughts are leading to increased competition for freshwater among municipal, agricultural, power generation, and industrial manufacturing venues. Consequently, it's critical to maximize product water yield from brackish sources and minimize adverse envionmental impacts caused by waste disposal.
