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.
The high microorganism retention rate and high treatment capacity enable a smaller wastewater treatment tank.
By utilizing KURAGEL™, capacity can be increased with just a small-scale conversion of the existing activated sludge tank.
Has the strength to withstand mechanical agitation for efficient denitrification.
KURAGEL™ controls the generation of sludge by preferentially promoting the proliferation of microorganisms such as bacteria that purify wastewater. In addition, Kuraray’s wastewater treatment system utilizes the self-oxidation mechanism of microorganisms to significantly reduce sludge.
