Chemically contaminated effluents, blow-down effluents, ultra-filtration wastes from water treatment plant, and stripped acid waste waters are discharged into the second system of production and storm wastewaters. Waste water of I and II systems undergo separate parallel mechanical and physical-chemical treatment in grit catchers, oil traps, radial-flow settling tanks and flotators. The treatment facilities are designed for treatment of effluents contaminated with oil products and suspended substances.
