PoilWater system is the best option for purifying oil from water, which has 2 outlet and inlet ducts. This product has negative return edges with adsorbent plant nanoparticles. An oil pollution sensor is installed inside this product. At the first inlet, the combined water and oil enter the system, and after the initial treatment, direct the water to the water tank separately. If the oil contamination sensor at the water outlet detects that oil is still present in the water, it repeats the purification cycle to fully purify the oil from the water. After separation, water and oil are directed to two separate tanks. The size of this product depends on the flow rate of oil-water that should be treated.
