Kelvin Water Technologies provides consulting, manufacturing, and maintenance services for a nanofiltration plant. Nanofiltration is a process used to treat water and wastewater by removing salts and other impurities from the water. Nanofiltration plants are used in a variety of applications, including drinking water treatment, industrial wastewater treatment, and desalination. Nanofiltration plants are typically smaller than traditional filtration plants, making them more efficient and cost-effective.
