Thermal disinfection type reverse osmosis membrane OV-L-HSF
● Pure water system for hot water disinfection
● Product performance and characteristics
Heat sanitizable reverse osmosis membrane element (HSF) is a product developed to meet the needs of pasteurization in food and pharmaceutical industries. Its sanitary open shell and accessories can eliminate the stagnant water area between the membrane element and the membrane shell. It is used in pure water systems that can be disinfected with hot water. The elements can withstand short-term hot water disinfection, so as to avoid the use of chemicals for sterilization and disinfection.
