ESPA2 reverse osmosis membranes provide optimum salt rejection and permeate flows. They are chosen when lower permeate TDS and lower feed pressures are needed. ESPA2 reverse osmosis membranes offer highest energy efficiency at lowest costs and are used in large municipal wastewater reclamation plants. ESPAB are low pressure brackish water reverse osmosis membranes having a high rejection for boron.
ESPA2-LD reverse osmosis membrane is available in diameters of 4.0 and 8.0 inches.
The ESPA2 reverse osmosis membranes are available in the LD variant. Low differential LD Technology® models are offered to minimize colloidal fouling when used with conventional pre-treatment equipment. These reverse osmosis membranes offer consistently low feed pressures and longer intervals between cleanings.
