Vacuum Filtration

PRAB’s line of vacuum filters range from standard off-the-shelf units to custom-engineered systems, with filtration capability up to 4,000 gpm.

Reverse Osmosis System

Typically for industrial, metalworking, and surface treatment applications we use our RO technology as a final process after Ultrafiltration or chemical treatment of waste and feed water.
