Cost Reduction Analysis: Oily Wastewater Reuse

Currently, a plastic products manufacturer collects and disposes of approximately 2,000 gallons per week of oily wastewater. The oily wastwater is collected primarily by mopping the production floor where it is common for hydraulic oil leaks to periodically occur. The oily wastewater is pumped and disposed of by an approved waste service at a cost of $0.33 per gallon.

The proposed EnviroSep Fluid Recovery System will allow for disposal to Sanitary Sewer or reuse of 90% or greater of the cleaned oily wastewater permeate. The result is that only 10% or less of the oily wastewater would require disposal by the waste disposal service.

The below listed savings are based on operation of the EnviroSep Fluid Recovery System only 50 days per year.
