Industrial Waste Water Treatment

National Pressure Pressure Washers

National Pressure offers three categories of products to remove contaminants from water: oil/solid coalescing, evaporators and media filtration. The National Pressure Coalescing Plate Oil-Water Separator removes free oil and solids from water and produces effluent with less than 10mg/L of oil droplets larger than 20 microns. Our evaporators minimize your expenses by evaporating the water from your waste stream at up to 30 gallons per hour, leaving only a sludge for disposal. National Pressure's affordable, easily maintained media filtration water recycling systems are designed for use with high pressure washers and steam cleaners. You get high quality water for reuse in your pressure cleaners or for safe discharge to your city sewer system.
