Variable Brackish Water Salinity
There are many areas in which the salinity levels of feed water vary over time, such as a well with salt water intrusion or a facility that makes up process water from multiple sources, including reuse. Until recently, reverse osmosis (RO) was the only desalination method used to treat feed water with variable salinity. Unfortunately, RO cannot put out water of the same quality when the brackish water salinity levels change. The NEXED module is designed with an adjustable desalination capability, which ensures that it delivers water of the same quality regardless of the salinity level. And, it does it while using optimum energy.
Brackish Desalination: USed for Water Softening
Because of its unique design and capabilities, the state-of-the-art NEXED module is being considered as a treatment for ion exchange regenerant brine produced by water softening systems. This technology recovers water and concentrate waste, and can thereby reduce your process and disposal costs.
High Brackish Water Salinity
In applications with high levels of salinity, the module is being considered as a pre-treatment for RO. By producing a feed with reduced total dissolved solids (TDS), the NEXED module can extend the life of RO systems. Additionally, because of the low-energy membranes, higher salinity applications can be treated with low pressure (<24PSI). The operating pressure expands the applicability of this electrochemical process.
