[0002] Common reverse osmosis devices on the market typically use tap water or groundwater as raw water, which is then treated by reverse osmosis to produce pure water with a conductivity of <10μS / cm. However, when used in the field of wastewater treatment, these reverse osmosis devices may experience excessive load, leading to unstable operation, damage to membrane elements, blockage, and the inability to produce water or produce water that does not meet the standards.
