The first requirement in any filtration/recycling system is to remove solids from the collected wash water.

When oil or grease is present in recovered wash water, it must be removed, most commonly to less than 100 parts per million (PPM). Free-floating oils can be coalesced and then skimmed away for removal.

Bioreactors are the basic filtration method used by industrial and governmental sewer plants. Any industry producing wastewater from washing can benefit immensely from the proper use of the Bioreactor.

Multi Media Filtration uses job specific media designed for a specific task; like emulsified oils, fine solids, metals and more, to be used to filter wash water to a level that the filtered water can be discharged to sewer or recycled.
