The oil-water separator adopts new technology,scientific processing flow and structural design.Based on the difference in specific gravity between water and oil,the oil particles float on the water surface after a slow flow over time and collision with the partition.Its unique multi-stage processing and separation device adopts inclined plate and corrugated plate oil separation technology.After several layers of inclined plate collision and multiple layers of corrugated plate diversion separation and adsorption,the liquid level automatic control technology can automatically separate the mixed oil and fat in oily wastewater and concentrate it in the oil collection tank for discharge without any power or additives.
