The influent capacity of landfill leachate is 120m³/day.


Project challenge: very high COD, very high TDS, poor biodegradibility.

The original project design  was MBR+ spiral RO, the effluent was not up to discharge standard. RO system was unstable and serious fouled.

In April 2016, MEIFUTE took over the project, using AO-MBR + DTRO. The discharge meets the "municipal waste landfill pollution control standard" (GB16889-2008).
