Oil free Wash Water
Oil-free washing water is produced in the operation of car wash stations and washing cars using high-pressure cleaners. Special recycling systems save fresh water, reduce operating costs and comply with current environmental regulations.
The application of HDR 777 in combination with professional high pressure cleaning leads to decisive advantages. Use of the HDR 777 permits savings of up to 85% for fresh water and detergents for vehicle and engine washes. Also concentration of hydrocarbons after treatment with HDR 777 is within limit values for waste water discharge.
Reclamation of oily waste water (oil content 5 - 30 mg/l) for high pressure cleaner with water demand up to 1,200 l/h as an innovative and efficient filtration for reusing water for wash processes, combined with chemical free retention of hydrocarbons and tensides for discharge into public sewer system with unbeatable price efficiency ratio.
