Types of oil separators:
• with gravitational filter
• with coalescent filter
• with sorption filter
They are used for waste water treatment from industrial plants, gas stations, car wash stations, agricultural farms, etc., or anywhere where there is a contamination of rainwater or process water with oily liquids, and the recipient is a collector-sewer. They work on the principle of smaller weight liquid. The expected concentrations of oil at the separator outlet is 70-100mg / l.
Oil separators with coalescent filter
They are designed in accordance with EN 858-2, and are used to treat waste water from industrial facilities, gas stations, car wash stations, agricultural farms, etc., or anywhere where there is a contamination of rainwater or process water with oily liquids, and the recipient is water of the 2nd Category watercourse. Guaranteed oil concentration at the outlet of the separator is 5 mg /l.
In accordance with EN 858-2, oil separators with coalescent filters according to the size of the sludge space are:
BP OLEX M/KF
settling volume = 100 × Q (l / s) roads, parking lots, covered gas stations
BP OLEX L/KF
settling volume = 200 × Q (l / s) gas stations, car wash stations, car repair shops
BP OLEX XL/KF
settling volume = 300 × Q (l / s) Car wash stations suitable for large vehicles, agricultural and construction machinery
Oil separators with sorption filter
They are used to purify precipitation water, technological or process water from oil, where the recipient is a water supply area. The filter is made of polypropylene fibers with a specific density, which have the property to repel water and absorb oil. Sorption filter is set up after the water is already treated in the separator with coalescent filter. Guaranteed oil concentration at the outlet of the separator is from 0.5 to 0.2 mg / l.
Oil separators with bypass
Separators with bypass are designed so that the waste water is treated to a nominal size. During heavy rainfall, the first onset of contaminated water passes through the separator through a filter which allows the purification of water. As the precipitation increases, the amount of oil is reduced significantly, and, instead of through the filter, the water flows into the recipient through a bypass.
The classification of the separators depends on the required parameters of the wastewater.
