1、 CPA3-8040 RO membrane product description:

ESPA typereverse osmosis membraneThe component is an energy-saving ultra-low pressure high-throughput composite reverse osmosis membrane launched by the American company Heidelberg in May 1995. It has ultra-low operating pressure (reduced by about 25% -40% compared to conventional low-pressure composite reverse osmosis membranes) and higher water flux while maintaining high desalination rate. The ESPA series reverse osmosis membrane components are used for water pumpspressure vesselThe supporting equipment such as pipelines and valves provide greater selection space, and the use of low-power motors can meet the needs of work. All of these have significantly reduced equipment manufacturing costs and system operating expenses, and saved a lot of energy, makingReverse osmosis desalinationTechnology is being more widely promoted and recognized.
As people continue to demand higher operating pressures for reverse osmosis membranes, Heidelberg Corporation in the United States has continuously enriched and improved its ultra-low pressure reverse osmosis membrane ESPA ® Series. At present, ESPA ® The series of 8-inch membrane components has developed into five models: ESPA1（Standard SuperLow pressure reverse osmosis membrane）、ESPA2(High desalination rate ultra-low pressure reverse osmosis membrane) ESPA4 (high water yield ultra-low pressure reverse osmosis membrane), ESPA2+(high membrane area and high desalination rate ultra-low pressure reverse osmosis membrane), and ESPAB (high boron removal ultra-low pressure reverse osmosis membrane), 4-inch membrane elements have also developed into three models: ESPA1-4040, ESPA2-4040, and ESPA4-4040.
So far, the ESPA of Heidelberg Corporation in the United States ® The series of ultra-low pressure reverse osmosis membranes is the membrane element with the highest water production, lowest operating pressure, and the highest desalination rate under the same operating conditions in the world. When the salt content (TDS) of the influent is below 1000 mg/L, ESPA ® The series of membrane components have irreplaceable advantages (please refer to the following models for detailed specifications and performance).
