CHEMICAL PROCESSING / CRITICAL FILTRATION APPLICATIONS

Fully Automatic | 1 Micron Filtration | Dry Solids Discharge (80% - 95%) | Cake Wash & CIP Options

The Oberlin Pressure Filter is a fully automatic filter that operates at up to 40-psi differential pressure to remove solids from liquids. The result is filtrate quality down to 1 mg/L at 1 micron and dry solids discharge at up to 95%. The Oberlin Filter is extremely versatile and is able to handle both extremes of the filtration spectrum.

  • High solids (1% – 20% for many applications) – If it can be pumped, it most likely can be handled by an Oberlin Filter
  • Low solids polishing – Filtration down to 1 micron. The Oberlin Filter can function as an automatic 1-micron cartridge filter.

Replace older, problematic equipment with an Oberlin Filter to recover/re-use your process liquid, or recover/reclaim your process solids.

OBERLIN PRESSURE FILTERS

Used in place of other liquid solid separation technologies.

1. FILTERING CYCLE

The pneumatic actuator moves the filter chamber (platen) into position, and holds it against the other chamber. Platen seals on the perimeter of the chamber create a liquid-tight seal around the filter media (disposable or semi-permanent belt). Solids-bearing liquid is pumped into the upper chamber, where the solids are trapped by the filter media. Pump pressure continues to force the liquid through the filter media and the previously collected solids.

2. DRYING CYCLE

When the pressure inside the filtering chamber reaches 30-40 psi, compressed air or other inert gas is fed into the upper chamber. This forces the remaining liquid in the chamber through the trapped solids and filter media. After all the liquid is evacuated, the cake is further dried using the compressed air. Once the drying cycle is complete, determined by backpressure and elapsed time – the chamber is lifted.

3. DISCHARGE CYCLE

Once the chamber is lifted, the solids (filter cake) are automatically discharged by advancing the filter media one section. After discharge, the upper chamber descends and a new filtering cycle begins. This sequence continues automatically until ended manually or via electrical signal.

OBERLIN FILTER'S OLIMIN8R® - REQUEST AN ESTIMATE

"The results were immediate; the tools did not clog, per shift filter changes went away due to a roll of filter paper in the OLIMINI8R last 2-3 months and tank cleanings went from every 30 days to 180 days. Even our Operators are impressed with how easy the controls are to use and maintain. The OLIMIN8R has significantly improved our operations, saved us time and money and improved overall employee morale.”
Forrest K.Maintenance Supervisor
“Great filter, great service and great business partner”.
