Aqua Clear manufactures a full line of commercial and industrial custom Nanofiltration (NF) systems. Nanofiltration is a membrane separation process that utilizes high selectivity characteristics, which effectively remove divalent ions such as calcium and magnesium from water. In essence, this characteristic makes NF membranes known as “softening membranes”. Nanofiltration is not as selective as Reverse Osmosis (RO), making NF a less energy intensive process. Custom nanofiltration systems are commonly implemented on surface waters (lakes, ponds and rivers), food and beverage processing and other industries where water purification and softening is required. NF membranes also effectively remove simple organic molecules (e.g. humic/fulvic acids), making NF processes highly efficient in color removal of feed waters with dissolved, decomposed organic material.
