The Hydenex ESPA2 MAX series has a higher specific water flux than the CPA series
Features of Hydenon ESPA2 MAX series energy-saving ultra-low pressure reverse osmosis membrane elements.
Features of ESPA series ultra-low pressure reverse osmosis membrane elements.
Since reverse osmosis membranes need to overcome osmotic pressure when working, the high energy consumption has always been a weakness of reverse osmosis technology. The ability to produce the required demineralized water at lower pressures means savings in equipment investment (pumps, valves, piping and pressure vessels) and operating costs (electrical energy consumption and maintenance) for the reverse osmosis membrane system.
Table 217 ESPA listed"The performance characteristics of the series of ultra-low pressure reverse osmosis membrane elements, as well as those with CPA"Comparison of a series of low-pressure reverse osmosis membrane elements. The specific water flux in the table represents the water yield of the membrane element per unit pressure, unit area, and unit time, a parameter that allows different membrane elements to be compared under the same conditions. Thus it can be seen that:
The ESPATM series has a higher specific water flux than the CPA series, where ESPA4 reaches 726LMH MPA, which is one of the reverse osmosis membrane elements with the highest specific water flux in the world;
The membrane area of ESPA2 Max increased by 10% to 440 ft?. This allows ESPA2 MAX to operate at ultra-low pressures.
The series has the highest desalination rate, and has a high water yield, and its specific water flux reaches 440lmh/mpa;
