ESPA2-LD-4040 Ultra-Low Energy 4" x 40" Reverse Osmosis Membrane Element

Hydranautics ESPA2-LD-4040 membrane provides optimum salt rejection and permeate flows and features Hydranautics Low Differential LD Technlogy to minimize colloidal fouling when used with conventional pre-treatment equipment. Hydranautics ESPA2-LD-4040 membranes offer consistently low feed pressures and longer intervals between cleanings.

ESPA2-LD-4040 membranes are commonly chosen when lower permeate TDS and lower feed pressures are needed. Offering the highest energy efficiency at lowest costs, ESPA2 elements are used in large municipal wastewater reclamation plants.

ESPA2-LD-4040 is the replacement for Hydranautics ESPA2-4040 membrane element, which has been discontinued by the manufacturer.
