The replacement cycle of reverse osmosis membrane is affected by many factors, including raw water quality, operating pressure, operating temperature, pretreatment effect, etc. Generally speaking, the replacement cycle of reverse osmosis membrane is 1-3 years, but the exact replacement cycle needs t Read More

Ineffective monitoring of residual chlorine in reverse osmosis equipmentIf the pump for adding NaHSO3 fails or the liquid fails, or the membrane is damaged by residual chlorine when the activated carbon is saturated.Improper cleaning and incorrect cleaning methods lead to damage of membrane performa Read More

White or black suspended particles appear in pure water Solution: This is because the pipeline is contaminated, resulting in the growth of bacteria. This situation should be dissolved caustic soda into the precision filter, operate the regulating valve to close the waste water, pure water open to a Read More

What is the maximum allowable downtime without system flushing?If the system uses scale inhibitor, when the water temperature is between 20 and 38°C, about 4 hours; below 20°C, about 8 hours; if the system does not use scale inhibitor, about 1 day.Can the reverse osmosis pure water system be started Read More

1、How often should the reverse osmosis system be cleaned?In general, when the standardized flux decreases by 10-15%, or the system desalination rate decreases by 10-15%, or the operating pressure and differential pressure between segments increases by 10-15%, the RO system should be cleaned.Cleaning Read More

In system operation, membrane contamination is a very difficult problem, which causes a significant decrease in the removal rate and water permeability of the reverse osmosis unit and membrane flux, as well as increasing the operating pressure of each section and contributing to higher operating and operational costs, which seriously affects the service life of the membrane and the development and utilization of reverse osmosis technology.
