Cleaning method for simple filtration systems

摘要: A method of cleaning a permeable, hollow membrane (6) in an arrangement the type wherein pressure differential is applied across wall immersed liquid suspension provided vessel (5), said being to outer surface permeable induce and sustain filtration through wall. The comprising steps of: suspending process; while continuing supply (5); aerating by flowing gas into (5) produce flow bubbles around dislodge at least some retained particulate material from surface; removing containing dislodged during step recommencing process.
