Features
       1, using filtered water for backwashing, no air source required, low operating cost.
       2The filter material has good oil resistance and does not need to be replaced. Just replenish10%every year.
       3According to the water outlet requirements, series or parallel operation can be flexibly adopted.

Scope of application
       Mainly used in petrochemical and other oily wastewater treatment filters, using walnut shells with strong adsorption capacity, stable chemical properties, high strength, and good wear resistance as the filter media. It can be used in single stage or series to ensure the quality of the effluent.
