These are HYDRACoRe10 and HYDRACoRe50 membranes made as a traditional RO style fiber glass element with a low fouling brine spacer used to treat industrial, food and beverage and municipal feed waters. These come in 4 inch and 8 inch diameter sizes.

These are high flow 720 Dalton MWCO TFC membranes used for color removal as well as acid and caustic reclamation applications due the membranes ability to reject fats, proteins, oil, color and other macromolecular species.

ESNA1-LF2-LD is a high flow nanofiltration membrane that provides superior Natural Organic Matter (NOM) rejection and moderate hardness rejection, operating at less than 100 psi pressures. Thus, the membrane offers savings in costs and energy. ESNA1-LF2-LD use patented Low Differential LDTM technology designed to minimize colloidal fouling.
ESNA1-LF2-LD membranes use a patented 34 mil thickness feed spacer that prevents colloidal fouling and increases effectiveness of membrane cleaning. As a result, the ESNA1-LF2-LD membrane does not need to be cleaned frequently – thus reducing treatment cost – while offering extreme durability and consistent performance. ESNA1-LF2-LD membrane is acclaimed for its high NOM and color rejection. It also significantly reduces operating costs. ESNA1-LF2-LD membrane is available in 8-inch diameter sizes.

ESNA4-LD’s selective separation capability using nanofiltration technology can be used to deliver high quality permeate water while removing specific contaminants such as nitrates and larger organic compounds from waters with low salinity.
Given this capability of ESNA4-LD, it finds its application in treating groundwaters used by farming communities where there is a need to remove nitrates which contaminate the water due to the use of fertilizers. ESNA4-LD also finds its use in the treatment of waters containing sulfates found in the wastewaters from the mining industry. Regulations governing sulfate concentrations have become more stringent as mine planners and operators are required to develop sulfate management in their water management plans with minimal impact on drinking water resources. ESNA4-LD membrane is available in 8-inch diameter sizes.
