Description

technical field [0001] The invention relates to equipment for producing drinking water through water treatment, in particular to a reverse osmosis water production equipment, a water production method, and a method for cleaning and maintaining the reverse osmosis water production equipment. Background technique [0002] At present, reverse osmosis (RO) technology is widely used in seawater desalination, brackish water desalination, industrial pure water, drinking water deep processing, material concentration, sewage treatment and other fields. For permeable membranes, biological substances in the water will accumulate and grow on the surface of the membrane during use, causing biological pollution, shortening the service life of the membrane, affecting the quality of produced water, and increasing maintenance and operating costs. Reverse osmosis membranes are poorly resistant to chlorine. It is difficult for biological substances to be completely killed by oxidants before en...
