With more than 4,700 installations in 77 countries, KWI excels in Industrial Waste Water Treatment, Biological Treatment, Process and Potable Water applications.

Dissolved Air Flotation (DAF) systems clarify wastewaters (or other waters) by using micro bubbles to separate solids from a wastewater stream and thus facilitate the removal of undesirable matter such as oils or suspended solid.

KWI Dissolved Air Floatation (DAF) solutions are based on proven process designs with exclusive, patented equipment and technology to meet our customers’ needs. The KWI brand name is synonymous with quality & efficiency and we strive for continuous improvement.

Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants, paper mills, food processing (including those where a high proportion of oils, fats and greases are present), biological sludge thickening, potable or process water production, general water treatment and similar industrial facilities. Key market applications and case studies can be found at our expertise page.
