Hydrocarbon separators
Hydrocarbon separators have been designed to take advantage of the different specific weights of solids, water and oils or fats. They constitute a compact unit which can be installed on the surface or buried. They are especially indicated for workshops, carwashes, part washing areas, mechanical industries, etc. The effluent enters the separator passing through the desanding area where suspension solids which might have come through are deposited. The waters are forced to circulate through the coalescent group, where the smallest particles are separated, which are deposited on the water surface. As floaters are accumulated the regulating valve buoy descends reducing the water exit, increasing the hydraulic level inside the separator and floaters reach the exits to the outside, whereby regulating valve buoy recovers its natural position, the hydraulic level inside the separator drops and the treated water can continue circulating at a normal flow rate. The deposited solids must be emptied periodically via aspiration through the manhole. It is convenient to empty the entire separator and clean the coalescent group with pressurised water once a year through the manhole.
