Oberlin Pressure Filter (OPF) Liquid-Solid Separations
The OPF has been used by the power industry for more than 40 years. Its automatic features, mechanical simplicity, dry solids discharge and low cost make it worth the time to evaluate when operator costs, hazardous exposure, and waste disposal needs to be minimized.
Filter Description
The OPF consists of an upper and lower horizontal compartment separated by the filter media. The filter cycle starts when the upper chamber closes against the lower chamber and forms a seal around the perimeter of the media. Slurry is then pumped into the upper chamber, through the media, and filtered liquid is collected in the lower chamber and drained out. During this feed step solids accumulate on top of the media forming a "cake". As the solids increases in depth the filter pressure rises. At a pressure set point feed is stopped and pressurized air is fed into the upper chamber to dry the filter cake. Next the upper chamber raises and the solids are discharged by auto-pulling out the media. The dry filter cake and filtrate is collected and handled by the customer.
Wide Range of Media Selections
The pressure filter can be set up to utilize reusable or disposable media and remove solids from 1000 to 1 micron.
Process Conditions
- Corrosive - Stainless Steel and Nickel alloys are available.
- Temperatures up to 1400C.
- Explosion Proof
- Cake washing
Automatic for Operator Safety
The OPF frees up the operator for more important tasks and eliminates exposure to the solid and liquid. The dry solid discharge minimizes liquid loss and makes for easier solids handling for disposal or continued processing.
Applications
Include straining, evaporator purges, reactor precipitates, clarifier sludges, scrubber blowdown, large filter backwash and cooling tower purges.
Testing
Free testing available.
