Process Wastewater Technologies LLC (PWTech) is a leading American manufacturer and supplier of unique technologies for use in the water and wastewater industries throughout North America. It is best known for supplying Volute™ technologies for sludge thickening and dewatering, and screening products primarily utilized in the CSO/SSO market. The products PW Tech supplies are all unique and hold the distinction of being unequivocally the best available technologies in the applications they serve. PWTech undertakes all its manufacturing in the USA utilizing using only American produced Stainless Steel (No Carbon Steel) for the manufacture of its products. Few other manufacturers in the industry can claim this. PWTech's initial success was based on a high-rate screening technology known as continuous deflective separation (CDS), refined by PWTech engineers. Developed during the early 1990s, continuous deflective separation rapidly became the number one technology across the United States for storm water treatment, and then was adapted to be utilized in the treatment of CSOs as well. Process Wastewater Technologies continues to be a leading manufacturer of products for the wastewater and CSO treatment industry. The Volute Dewatering Press has become an increasingly popular choice for automated, low-maintenance dewatering, replacing conventional belt presses and screw presses to provide a 21st century dewatering method, while new Raked Bar Screens and CDS solutions are installed across the United States.
