To effectively treat water, various filters are used, which differ in parameters and characteristics. The purpose of this work is to determine the possibility of replacing cartridge filters used at PetroKazakhstan Oil Products LLP with easily regenerable bag filters. In the course of the research, it was found that the use of cartridge and bag filters contributes to more effective water treatment, in particular, from suspended sub- stances. When comparing them, we can say that the latter is advantageous in that it does not need to be changed when clogged, like a cartridge filter, but simply rinsed and used again in the technological chain. The bag element is quite simply washed in water, but if it is heavily clogged, it can be washed either in a solution of citric acid (20 g/l) or in an alkali solution (10 g/l).</p>cartridge filterbag filterprocess flow diagrampilot plantturbiditysuspended solidsfiltrationregenerationкартридж сүзгісіқап сүзгісітехнологиялық сызбапилоттық қондырғылайланутоқтатылған заттарсүзурегенерациякартриджный фильтрмешочный фильтртехнологическая схемапилотная установкамутностьвзвешенные веществафильтрациярегенерация1.Burenin VV.
