FIELD: sewage structures, particularly devices for separating oil, water, or grease from sewage in drains leading to the main sewer. ^ SUBSTANCE: device to separate two immiscible liquids having different specific gravities, namely to remove oil products present in rain sewage water uses coalescent filter as separating member. The coalescent filter is layer of liquid having lesser gravity. Device is made as vessel with vertical partitions installed in the vessel. The partitions define sections made as communicating chambers. Even-numbered vertical partitions have lower water channels, odd-numbered ones are provided with upper overflow means. Each next odd-numbered vertical partition has height lesser than that of previous one. Each above section comprises removable filter immersed in upper part of low-gravity liquid, namely of coalescent filter. The filter may slide in vertical direction and is formed as hollow tank with horizontal slotted partitions and is filled with filler, namely with sorbent. Tank periphery mates perimeter of each vessel section. The device comprises flow meter installed on even-numbered vertical partition with lower water channel and including rotary gate arranged in water channel of the partition. Rotary gate axle is vertical and connected with liquid level indicator over water surface. Liquid level indicator is linked to liquid flow summarizing means and flow regulator. ^ EFFECT: increased operational efficiency. ^ 2 dwg |
