Treating water for solid impurities using helical filter elements with dynamic perlite membranes

The work represents results of studying the process of creating dynamic perlite membranes on Krapukhin’s Filter Elements (KFEs). It has been shown that KFEs with pore sizes of 25–55 ?m are the most suitable for creating a perlite precoat layer. Test results of the installation based on four KFEs in advanced treatment of water for solid impurities at Mosvodokanal wastewater treatment facilities are represented. It has been shown that the application of KFEs with a dynamic perlite membrane allows one to treat water from solid impurities with an efficiency of over 98%.
