FIELD: process engineering.
SUBSTANCE: invention relates to self-purifying filters. Proposed method comprises rinsing filter elements by forcing purified liquid in back direction and straining filter elements. Filter elements are made of elastomer material with channel structure of flow holes. Rinsing id performed under pressure. Straining is performed by bending and expanding to increase cross section of flow channels.
EFFECT: clearing filter elements surfaces and channels, cleaning surface of salt sediments.
