Separators are devices designed to separate and retain petroleum derivatives as well as suspended minerals (sand, sludge) that rainwater and meltwater flowing from any kind of watershed may contain.
ESL-Z separators were tested for nominal and maximum flows and the results of the tests were confirmed by the Building Research Institute by issuing the National Technical Assessment ITB-KOT-2017/0212 edition 1. ESL-Z separators represent class I (according to EN 858-1), it also obtained CE mark allowing to be applied in all EU countries. The chamber is made in accordance with Norm EN 1917 or National Technical Assessment ITB, concrete of class at least C35/45 waterproof ≥W8, with water absorption lower than 5%, frost resistant F150 in the water and F50 in 2% NaCl, stable for petroleum products in accordance with EN 858-1.
Lamella separators separate petroleum derivatives using floatation and sedimentation processes. Wastewater flowing through rainwater drainage system flows into a separator through an inflow chamber which construction enables evening and directing of wastewater flow.
All impurities are separated during multi-layer flow of the wastewater through lamella section. Next, the treated wastewater flows into an outflow chamber (optionally with an anti-backflow flap). The technology of petroleum derivatives separation used in the device enables also to separate any impurities that can easily form sediment at the bottom of the separation chamber.

The lamella section is a replaceable element with two grips for easy taking it out of the separator. Cleaning of the separator can be done from the outside and does not require coming down into the device.
Oil separators are installed in rainwater drainage systems as one of the devices used in pretreatment of rainwater from watersheds that are likely to be polluted by petroleum derivatives – urban, road and facility:
- roads and motorways
- car parks
- railroad areas
- public transport areas
- transportation equipments depots
- production plants, etc.
