Petrochemical wastewater contains a lot of dirty oil, which is easy to form liquid area oil when it is stored and adjusted in the tank. The Floating Oil Skimmer developed and manufactured in the clarification environment can use the floating circulation separation technology to make the dirty oil float up and down slowly with the liquid level without affecting the normal function of the regulating tank, so as to form a gravity separation environment, The tiny oil droplets will float to the surface under the action of gravity, and the floating oil will be concentrated and discharged to the center due to centrifugal force.

The waste water in the tank is easy to form precipitated sludge at the bottom of the tank, which is difficult to discharge. The Bottom Scraper can be used in flat bottom tanks. The hydraulic motor drives the double truss working bridge to drive the scraper to circulate around the bottom of the tank, scraping the sludge at the bottom of the tank from the center to the periphery, and discharging the sludge out of the tank after it falls into the sludge outlet.
