Options for ULTRA FILTRATION water treatment
Nimbus Water range of Ultra Filtration, known as UF systems, available, where require a high purity of drinking water quality. Source, or raw water is filtered to 0.03 micron. Ultra filtration, as inline water treatment and filtration systems, fall in the range, close to reverse osmosis. Rated, the purity level at +-90%, leaving behind some in-organic minerals in the water. For users that require some minerals retained in the treated water, for their drinking water, ultra filtration is a approved NSF system.
Ultra filtration is a membrane liquid separation technology that is positioned close to reverse osmosis and nano-filtration. While RO can remove the smallest of solute molecules, in the range of 0.0001 micron in diameter and smaller, nanofiltration (NF) removes molecules in the 0.001 micron range and Ultra Filtration, 0.03 micron.
NF is a poly piperazine amide membrane and is essentially a lower-pressure version of reverse osmosis where the purity of product water is not as critical as pharmaceutical grade water, for example, or the level of dissolved solids to be removed is less than what is typically encountered in brackish water or seawater. As such, nanofiltration is especially suited to treatment of well water or water from many surface supplies.
Nanofiltration is used where the high salt rejection of reverse osmosis is not necessary, and yet NF is still capable of removing hardness elements such as calcium or magnesium. Sometimes referred to as "membrane softening", nanofiltration is an attractive alternative to lime softening or sodium chloride zeolite softening technologies. And since NF operates on lower pressure than does RO, energy costs are lower than for a comparable RO treatment system.
