Water softening

Water softening is an important part of water conditioning and purification.

High hardness leads to scale formation in water heating units of household and industry purpose, in steam boilers as well as to formation of salt deposits on dishes. The scale formation leads in turn to overheat of electrical surfaces, high consumption of electrical power and finally to breakdown of instruments and equipment. However water with high hardness also has an off-flavor taste (has low organoleptic properties) and also food, tea, coffee with this water lose their flavor.

Ion exchangers fibrous 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-size low-head installations of industry and household purpose.

Variety of textile forms enables to use materials Panion® in water purification installations of different construction and purpose, and high mechanical strength and osmotic stability make it possible to use ion exchangers fibrous in multiple cycles «sorption-regeneration».

Materials PANION intended for removal of hardness salts from water

Panion 110 — removal of ions of heavy metals, water softening

Fibrous ion exchanger PANION 110

PANION 110 — weak-acid fibrous cation exchanger, an analogue of well-known trademarks VION, FIBAN, MION.

Applications:

  • Air purification from volatile substances of base nature: ammonia, amines, alkalis etc. Panion 110 can be applied in industrial and domestic air cleaning systems;
  • Water purification from the ions of heavy metals, water softening;
  • Human protective means (respirators, gas-masks, protective costumes etc): removal of vapors of ammonia and amines.
