Water softening
Water softening is an important part of water conditioning and purification.
High hardness leads to the formation of scale in water heating units for domestic and industrial use, in steam boilers as well as the formation of salt deposits on dishes. The scale formation, in turn, leads to overheating of electrical surfaces, high energy consumption and ultimately to failure of devices and equipment. However, water with high hardness also has an unpleasant taste (has low organoleptic properties) and food, tea, coffee with this water lose their flavor.
Fibrous Ion Exchangers Panion® are effective means for removal of high content of hardness salts caused by occurrence of calcium and magnesium salts.
Thanks to their properties fibers Panion® remove ions of hardness 10-100 times as fast as common granular ion exchangers that makes possible to use they in small-sized low-pressure installations for industrial and domestic use.
The variety of textile forms allows the use of Panion® materials in water purification installations of different construction and purpose, and high mechanical strength and osmotic stability make it possible to use fibrous ion exchangers in multiple «sorption-regeneration» cycles.
