Oli-water separator for bilge containing fine suspended substances

摘要

For treating bilge containing solid matters and emulsion securely, an oily water separator includes a first treater 1 for separating oil ingredient roughly from bilge by gravity separation and removing fine suspended matter from the bilge by sand filtering, and a second treater 10 for separating and removing oil ingredient remained in the bilge treated by the first treater. The first and second treaters 1, 10 are connected directly by a feeding pipe 8. The first treater 1 includes an oil discharge portion 5a above an oily water inlet 2 and a filtering sand layer 3 below the oily water inlet 2. The second treater 10 includes a coalescer 19 in a lower room 29 to communicate with the upper room. <IMAGE>
