How to decide which series of reverse osmosis membranes
The reverse osmosis membrane on the market dominated with Hyde's SP series of very low pressure reverse osmosis membrane PA series ultra low pressure reverse osmosis membrane ESPA series ultra low pressure reverse osmosis membrane CPA series of anti pollution brackish water desalination membrane HPA series of anti pollution brackish water reverse osmosis membrane HPA-FR series of anti pollution high desalination reverse osmosis membrane HY series of home SW series reverse osmosis desalination membrane. How to choose the appropriate reverse osmosis membrane elements has gradually become a required course for water treatment.
Decide which series of reverse osmosis membrane should be selected according to the requirements of the end user for the desalination rate, the requirements of operation pressure, the requirement of pollution speed and frequency, and the water quality of the influent.
Ultra low voltage energy-saving series of composite membrane components, low pressure and high desalination rate series of composite membrane elements and low pollution series of composite membrane components called brackish water film, are used in the influent salinity rate is lower than the 10000mg/L of brackish water desalination on the occasion, the influent salinity was higher than that of 15000mg/L seawater use series of composite membrane element and when the influent salinity ranged from 10000 ~ 15000mg/L of the occasion, should according to the system recovery rate, inlet temperature and operating pressure to determine the type selection of membrane element.
The brackish water situation, if the requirements of the system energy-saving end users, so ultra low energy saving composite membrane element is the best choice, if the requirements of the end user system high desalination rate, then the low voltage high desalination rate series of composite membrane element is the best choice, if the water quality is poor surface water or wastewater, so low pollution series the composite membrane element is the best choice.
