Resins & Filtermedia
Water softening ion-exchange resins are used to replace the magnesium and calcium ions found in hard water . The resin can be regenerated by washing it with salt (NaCl). The calcium and magnesium ions migrate off the resin, being replaced by sodium ions from the solution until a new equilibrium is reached.
Mixed bed resins contain both cation and anion resins so most minerals are held within the resin and pure water is produced.
Nitrate removal resins, macroporous strong base anion resins, specially designed for the removal of nitrates from water for potable processes.
Scavenger resin is a food grade, strongly basic, macroporous type I anion exchange resin based on polystyrene, suitable in the chloride form for the decolorisation of:
- juices from sugar production, especially beet sugar
- solution of organic products e.g. glycerine, amino acids
Turbidex, gravel and sand for sediment removal. Hydro-antracite is used in closed filter systems for purification of drinking water, process water, pool and waste water. This filter medium is usually combined with different sizes of filter sand in a multibedfilter
Activated carbon is an excellent choice for removal of chlorine , taste and odour , and or organics (colour) in water.
Bayoxide ® E33 absorbs and eliminates arsenic
MTM removes iron from water by oxidation and filtration
Birm removes iron and manganese
Juraperl is applied for deacidification of poor water,
Cristal Polyphosphates are crystals that are dissolved in water and avoid limestone deposit
Liquid silicates are dosed in the distribution of drinking water for the protecion of pipes against corrosion.
