Two stage disc tube reverse osmosis system is a set of equipment to remove the unexpected contents in waste and /or drinking water. It is one of the most cutting-edge technology for drinking water purification and waste water treatment.

Two Stage DTRO is widely used in landfill leachate treatment. The landfill leachate enters the conditioning tank, and the conditioning tank leachate is pumped to the leachate raw water storage tank. After simple pretreatment such as pH adjustment, sand filter, and security filter, it enters the first-level DTRO, and after the first-level DTRO treatment The generated permeate enters the second-stage DTRO for further processing, and the first-stage DTRO concentrate is discharged to the concentrate storage tank for refilling treatment. The permeate after the second-stage DTRO treatment enters the degassing tower for treatment and discharges after reaching the standard. The second-stage concentrated liquid returns to the first-stage DTRO and continues processing.
