Nk type combination filler is a combination of semi-soft center ring with soft filaments or flexible wire.The wide range of application, can improve the speed of the initial hanging membrane, having a certain gap variable, resistance to biological degradation, resistance to shock loading characteristics. Generic filler hanging membrane performance characteristics, particularly on the poor biodegradability of organic wastewater use in particular can be proved a popular among customers.
