Description
ESNA membranes are designed by Hydranautics using the latest technology and show unparalleled performance at very low pressures. ESNA membranes are ideal for softening applications and removing pesticides and pathogens and provide 91 to 99% of salt excretion. ESNA membranes also remove iron and TOC (total organic carbon), while allowing the passage of monovalent ions such as sodium and chloride. This makes them suitable for urban drinking water systems. Hydranautics Advanced membrane technology and the unique properties of ESNA membranes result in significant cost and energy savings. This makes this membrane a good choice for municipal drinking water systems.
ESNA types
- ESNA1-LF-LD
ESNA1-LF-LD are high-performance nanofiltration membranes that are ideal for removing pests, bacteria, and viruses. They significantly reduce salt disposal by 50 to 90 percent with very low-pressure operations, increased energy savings, and installation costs. They use the patented Low Differential LDTM technology, which is designed to minimize colloidal deposition. ESNA1-LF-LD membranes use a 34 mm thick feed spacer that prevents colloidal deposition and increases membrane cleaning efficiency. As a result, the ESNA1-LF-LD membrane does not require frequent cleaning, thus reducing the cost of filtration. The ESNA1-LF-LD membrane is available in 8-inch sizes.
- ESNA1-LF2-LD
ESNA1-LF2-LD is a high-flow nanofiltration membrane that rejects superior natural organic matter (NOM) and rejects medium hardness and operates at pressures below 100 psi. Therefore, the membrane saves costs and energy. ESNA1-LF2-LD uses patented LDTM differential technology designed to minimize colloidal deposition. ESNA1-LF2-LD membranes use a 34 mm thick feed spacer that prevents colloidal deposition and enhances the membrane cleaning effect. As a result, the ESNA1-LF2-LD membrane does not require frequent cleaning, thus reducing filtration costs while providing durability and consistent performance. ESNA1-LF2-LD membranes are highly regarded for their NOM and color rejection. It also significantly reduces operating costs. The ESNA1-LF2-LD membrane is available in 8-inch sizes.
- ESNA4-LD
Selective separation capability of ESNA4-LD using nanofiltration technology is used to provide high-quality permeable water and remove certain contaminants such as nitrate and larger organic compounds than low salinity water. Due to this capability of ESNA4-LD, it is used in groundwater treatment used in agricultural communities where there is no need to remove nitrates, which contaminate the water due to the use of fertilizers. ESNA4-LD is used in the treatment of sulfate-containing waters in the mining industry. Sulfate concentration regulations have become stricter as miners planners and operators are required to develop sulfate management in their water management plans with minimal impact on drinking water resources. The ESNA4-LD membrane is available in 8-inch sizes.
