After a period of normal operation, the reverse osmosis membrane element may be contaminated with suspended or insoluble substances that may be present in the feedwater. The most common of these contaminants are calcium carbonate scale, calcium sulfate scale, metal oxide scale, silicon Sediments and organic or biological sediments.
In this case,
The nature of the pollutants and the rate of contamination are related to the conditions of the water supply. Pollution is developing slowly. If the measures are not taken early, the pollution will damage the performance of the membrane elements in a relatively short time.
In this case,
Regular inspection of the overall performance of the system is a good way to confirm the contamination of the membrane element. Different contaminants can cause different degrees of damage to the performance of the membrane element.
