RO
The DTRO system can be operated in a flexible manner and can be selected as primary or secondary treatment according to the discharge standard required for leachate, and the treated water can be guaranteed to meet the primary discharge standard or water reuse standard of GB16889-1997. It is mainly used in projects such as landfill leachate, waste composting leachate and deep salt concentration with zero discharge.
The membrane used in DTNF-POS is also resistant to polar organic solvents and is encapsulated in a disc and tube without glue, so there is no risk of leaching in polar solvents during long-term operation.
