◎ Product Introduction and Application Fields

　　The DTRO disc-tube reverse osmosis membrane is a new, highly efficient special separation membrane developed by our company. This product has gained a significant foothold in China’s wastewater treatment sector for municipal solid waste and other industrial effluents. It boasts advantages such as high recovery rates, stable effluent water quality, strong resistance to fouling, long cleaning intervals, and resistance to clogging. It can effectively treat RO concentrate and high-concentration wastewater. Currently, it is widely used in leachate treatment, advanced treatment of municipal wastewater, reclaimed water reuse, zero-discharge of desulfurization wastewater from power plants, and high-salinity wastewater treatment.
