KURAGEL™ (PVA gel)

KURAGEL™ is a biocarrier that Kuraray developed as a raw material for PVA resin. It features higher bacterial retention than ordinary carriers, and enables more efficient wastewater treatment with a compact system. Kuraray provides wastewater treatment solutions that take advantage of the characteristics of KURAGEL™. One of these is the excess sludge reduction system ZECRUS™, a revolutionary wastewater treatment system that uses KURAGEL™ to substantially reduce generation of excess sludge by keeping the proliferation and death of bacteria almost equal.
