Anaerobic: anaerobic digesters, anaerobic filters, UASB or prefabricated reactors. Natural: stabilization lagoons, wetlands and bio gardens. Special: for industrial wastewater (microtamics, flocculators, DAF equipment, press filters, combined or sequential biological treatments, biogas production for energy use, etc.)
The filter press is most often used in the dewatering of metal finishing sludges because generally it is made to handle smaller volumes of sludge, is sim- ple to operate, and produces a dry, easily disposable filter cake. Sludge from the thickener, or directly from the bottom of the clarifier, is usually pumped via an air diaphragm pump to the ...

The technologies included within each PEWE DeWater ® DBP filter belt press maximize solids recovery while minimizing chemistry usage during sludge dewatering. Each filter belt press has a wide solids loading range and can accommodate future plant process changes as well as higher throughput or cake dryness requirements.
Sludge is generally conditioned before thickening and dewatering. Two types of conditioning chemicals are used to enhance the treatability of the sludge: Mineral chemicals such as iron salts and lime. These chemicals are frequently found in filter press applications. Organic chemicals such as coagulants and flocculants. The most common type of
HELLBENDER® White Water Systems (WWS) are specially designed to enhance the performance of dissolved air flotation (DAF) systems, which are used to remove solids, oils, and greases from water and wastewater. The HELLBENDER WWS is designed to either be a stand-alone system or to be retrofitted to an existing DAF previously fitted with an ...
