Oil and petroleum separator

Purifies surface wastewater from sand, coarse suspended solids, and dissolved petroleum products. It is installed after preliminary mechanical treatment, before discharge into the municipal sewerage system. It is also possible to use as a mechanical treatment facility, before the sorption filters. The body of the unit is made of reinforced fiberglass, which excludes deformation under the loads of soil and groundwater. Increased strength of the product is provided by the method of cross-winding.

Purification technology

Wastewater through the supply pipeline enters the sediment zone, where the flow velocity is averaged and heavy mineral impurities fall to the bottom of the unit.

Wastewater purification is achieved through the installed coalescing module, which enlarges the particles of petroleum products and ensures their floating to the surface.

The clarified wastewater is then discharged to the outlet branch pipe.

The sludge formed at the bottom of the sedimentation tank is periodically removed by the sludge removal machine through the service hole.

Upon request it is possible to equip the unit with sensors-signalizers of sand and oil products level for their timely pumping out. Recommended capacity is from 1 to 250 l/s.

Prior oil/petroleum separator installation, an excavation pit should be arranged: excavation works, water level reduction, sheet piling of the excavation walls (if necessary) and a reinforced concrete plate to which the oil/petroleum separator is fixed with synthetic bands (or bands of corrosion-resistant steel on the rubber seal) to prevent floating up under the groundwater pressure. After the oil separator is fixed, backfilling is performed, layer by layer with compaction by a vibrating plate, simultaneously on both sides of the separator body housing. After connecting the input and output branch pipes of the oil and petroleum separator to the collector of the rainwater treatment system, the service well (maintenance well) is connected and the secondary backfilling is performed. For more details please refer to the operation manual.

It is recommended that an oil/petroleum separator manufactured by NTT-Peresvet is maintained at least once a year, at the end of the working season. Maintenance of the oil separator includes pumping out the water containing accumulated oil products and sludge. If the oil/petroleum separator is equipped with sensors, they should be removed from the housing during pumping out to avoid breakage of the sensors, clean the sensors from contamination and test their operability. The coalescence modules of the oil and petroleum separator are auto-cleaning and do not require replacement or regeneration - cleaning is performed using non-expendable materials. After pumping out accumulated oil products, sludge and installing sensors in place, the oil separator must be filled with water up to the height (level) of the output branch pipe.
