Wastewater, which has undergone preliminary cleaning from sand and large mechanical impurities, flows by gravity into the receiving chamber of the oil separator. Further, oily effluents enter a coalescent ins ert of a cellular structure consisting of oleophilic PVC plates glued together in the form of inclined cells.
Water moves through the cells in a laminar mode, while the settled suspended matter rolls down to the lower part of the tank, and the emulsified and free floating oil products are attracted to each other (coalescence), to the cell walls and float up into the upper part of the tank, separated from the collection and receiving chambers of the semi-submersible partition.
Thus, in this device, two processes of separating oil products from the drain take place in parallel: thin-layer sedimentation of suspensions with hydrocarbons adsorbed on their surface and coalescence - adhesion and enlargement of floating and mixed particles of fuel and oils, which leads to their floating up. When moving in the coalescent module, the liquid causes vibration of the module plates, "shaking", which promotes the separation of drops from the walls of inclined cells and accelerates the ascent of enlarged particles of oil products, as well as the "sliding" of precipitated suspended matter.
Thus, the modules are self-cleaning. From time to time it is necessary to pump out the surfaced hydrocarbons in to a special container for the captured oil products, as well as the precipitated sediment for disposal at industrial waste landfills or transfer to a specialized organization for disposal.
Oil traps are designed to remove emulsified oil products and suspended solids from water supplied to rainwater treatment plants. It is used as part of local treatment facilities for surface runoff and as a separate stage for thin-layer sedimentation of suspensions and coalescence separation of emulsified petroleum products, gasoline, fuel oil, organic and mineral oils.
A special block of local treatment facilities for surface runoff from residential areas. It is a separate stage of treatment facilities for rain, melt and irrigation water from city buildings and highways.
The petrol-oil separator can be additionally equipped with a waste accumulation level alarm device. The alarm system consists of an electronic unit with sludge level and oil level sensors. The possibility of connecting additional sensors and equipment is provided.
The use of this system allows the accumulated waste to be removed from the tank in time and prevents the possible penetration of suspensions and oil products into the purified water.

Modern materials and technologies. Fiberglass products have a long service life - up to 50 years. And due to the significantly lower weight compared to traditional materials (steel, concrete), construction, assembly and transport costs are significantly reduced. HELYX composite products can be used in an aggressive environment and in areas with a seismic hazard of up to 9 points.
