Candle Precoat Filter (OPF)

A complete automatic cycling Pre-Coat filtration system consists of the Pre-Coat filter vessel, a patented slurry feeder for mixing and storing the pre-coat material, a Hydro-Vac secondary recovery filter to concentrate and remove the dirt loaded pre-coat powder after each filtration cycle, and a main system liquid reservoir.
The heart of the Pre-coat filtration system is a pressure vessel containing a packed array of wire-mesh-covered, perforated tubes. The tubes are attached to a baffle in the upper dome structure of the vessel. Fabrication of this assembly is such that any liquid flow, in either top-to bottom or bottom-to-top direction, must flow through the perforated tubes. The mesh-covered tubes serve as septum upon which a fine cellulose powder (or an alternative filter aid) is deposited in thin layers to form a filter cake. This filter cake permits removal of contaminant particles as small as 1/2 micron. When cellulose powder is caked on the filter septum, it becomes an excellent ultra-high filtration medium which permits liquids to flow through the microscopic pores in the cake but prevents the passage of suspended solids (i. E. Contaminants). In the filtration mode of operation liquid flows vertically up through the pre-coated filter tubes into the pressure vessel dome. From there the filtered liquid is transported to a clean liquid storage tank.
