SSENG's OASIS is the brand name of SSENG's watertreatment system using fiber filters. The DPPW(Double stagePCF filter for Portable Water)process is one model of SSENG'sOASIS . This process can produce potable water from thesurface water like river by direct filtration with coagulationusing two PCF(Pore Controllable Fiber) filters connectedserially.

Advantage of DPPW plant
Compact size
Excellent filtrate quality
Low level for chemical dosing rate
Full automatic operation
The DPPW process is very compact as 1/30 of the conventional, itsfoot print is very small, and so the construction cost is low.
The DPPW process can filter from 500 NTU of the raw water to around0.5 NTU (99.9%) directly.
Coagulant dosing rate of the DPPW process is below 2/3 of theconventional, since it can filtrate over 5㎛ particles.
The DPPW process can be automatically controlled by MMIincluding coagulant dose and backwash.
Minimum lead time Delivery term of the DPPW is 1/2 of the conventional, since itsmajor parts are stocked and installation works is minimized.
