The Spacer Tube Module (ST) is a new membrane structure specially developed for the treatment of high concentration and high salinity wastewater.
①Anti - pollution: The parallel flow channel design is adopted , and the pressure drop is smaller and the anti - pollution capability is stronger than that of the rolling type film diamond channel .
②The investment cost is low and the area is small: the membrane area is three times that of DTRO, and the investment is only 50-70% of DT, and the floor area is 1/3 of DT.
③High working pressure、high recovery rate：up to 120 bar , and recovery rate up to 95 % .
