Principle of operation

Hydrocarbon separators are designed for treating rainwater, snowmelt and post-processing water from areas at risk of contamination with oil-derived substances. They are flow devices, i.e. they mechanically separate free oils and other emulsions from the rest of sewage as it flows through the installation. The separation process uses the differences in the density of hydrocarbons and water. Due to their mode of operation, the separators also retain a portion of the settling suspension, which accumulates in a settling chamber at the bottom of the unit.

The basis for proper operation of the separator is the proper determination of the nominal flow (amount of rainwater flowing through the device [L/s]). It determines basic features of the separator: size of the separation zone, collection capacity of light liquids, working level of the liquid, volume of the settling tank. Proper selection of these quantities determines proper precipitation of petroleum substances from rainwater flowing through the separator through surface phenomena, while allowing larger drops to float to the surface. This phenomenon is accelerated and supported by coalescing cartridges in class I separators.

Application

JPR AQUA hydrocarbon separators are designed for sewage treatment for flows from 1.5 L/s to 1000 L/s. The separators are manufactured according to the PN-EN 858 standard and are CE marked. They are used in facilities such as:

  • petrol stations,
  • car and truck washes,
  • agricultural and construction machinery washing plants,
  • automatic vehicle washes,
  • small and large car parks,
  • underground car parks,
  • roads and motorways,
  • scrap yards,
  • airports,
  • ports,
  • refineries,
  • fuel storage and distribution centres,
  • garages,
  • mechanical workshops,
  • car workshops,
  • industrial plants,
  • equipment bases,
  • urban catchment systems,
  • passenger service points,
  • logistics centres.

Advantages of hydrocarbon separators

  • products manufactured in compliance with PN-EN 858-1 standard,
  • proven effectiveness confirmed by tests by the manufacturer and a notified laboratory,
  • products complying with the European Union directives (CE mark),
  • possibility to set the units at large depths, in places of motor vehicle traffic, above ground level, as well as at high ground water table,
  • products easy to install (especially low weight) and operate,
  • optional equipment (sampling system, superstructures, automatic liquid level/oil film thickness sensors).
