Products > Pearlcomb > Panel Membrane Type * A membrane of special specifications made in Japan is used for the ultrafine foam panel type. * Ultrafine foams provide a very high energy-saving effect. * Diffusers for sewage and night soil treatment plants. * Diffusers for industrial wastewater treatment plants. * Diffusers for agricultural effluent treatment. * Diffusers for livestock sewage treatment. * Diffusers for small combined purifiers. * Supply of oxygen to culture ponds. * Diffusion of exhaust gases. * Ultrafine foams released from the diffuser membrane efficiently circulate air (high mobility of oxygen). * Because the membrane pores are closed during shutdown, there is no sewage backflow or blinding of the membrane itself. Intermittent operation is also possible.
