In 1991, AMCON unveiled VOLUTE , which brought epoch-making innovations to sludge dewatering technology. The performance of dewatering equipment is enhanced by removing clogging which could considerably block the discharge of the filtered liquid. AMCON’s dewatering press is equipped with unique VOLUTE technology, which allows dewatering sludge while automatically selfcleaning the filter mesh. This enables stable and constant dewatering without depending on flush water for clogging prevention.
