Comelt treats coiled and capillary for processes such as reverse osmosis, nanofiltration, ultrafiltration and microfiltration. Main types are listed below: “Sea water” high rejection “Brackish water” high rejection “Brackish water” balow pressure “Low fouling” (RO & NF) Nanofiltration “Sea water” sweetening Ultrafiltration Microfiltration
Cationic, chelating ion exchange resin, with iminodiacetic functional groups. It’s particularly suitable for removing heavy metals, such as iron, copper, lead, nickel, zinc from those solutions with high calcium and sodium concentration. It displays very good ion exchange capacity and kinetics.
Strong cationic ion exchange resin with macro-porous structure and sulphur functional group. Particularly recommended for: Demineralization ( after transformation in H+ form) Process and waste water recycling Heavy metals recovery It displays remarkable ion exchange capacity and kinetics and high resistance to osmotic shocks and abrasion.
Weak, anionic ion exchange resin, with macro-porous structure and amine functional groups. It’s recommended for removing strong acid anions in demineralization cycles, after the strong cation resin phase. Its macro-porous structure allow also the removal of big organic molecules, protecting the strong anion resin phase from organic fouling.
Strong, type 1 anionic ion exchange resin, with gel structure and quaternary ammonium functional groups. It’s particularly suitable for removing anions, silica included; in demineralization cycles , in combination with a strong cation resin. It displays a high regeneration efficiency.
Stoichiometric mixture of strong cation resin and strong anion resin, named nuclear grade. It is produced through specific procedures which ensure an extremely low chlorides level and it is supplied in H+/OH- completely regenerated ion form. It displays high resistance to abrasion and osmotic shock.
Macroreticular strong base anion exchange resin type 1, with quaternary ammonium functional groups. It is recommended for the selective removal of nitrates in drinking water. Besides the preferential removal of nitrates in comparison with other anions (e.g. sulphates) normally present in the drinking waters, the macroreticular structure of AM-09-NT allows also the removal …
Ion exchange resin gel structure type II, strong base anion. It is recommended for anions removal in demineralization cycles, after a strongly acid cation resin. In comparison to a type I resin, AF-402-OH has better regeneration efficiency, but with lower affinity for silica. Therefore it is recommended when silica to total anion ratio …
Weak acid cation exchange resin containing carboxylic functional groups. It is recommended for temporary hardness and heavy metals removal from industrial and drinking waters. It has been particularly designed to be used in cartridges for domestic tap water treatment together with the nitrates selective resin AM-09-NT and with silver impregnated granular activated carbon CARBOSORB 1230 …
Mixed bed LM1 is a ionic balanced mixture of strong acid cation gel and strong base anion gel type 1. It is recommended for total demineralization of water (e.g. polishing) in regenerable or non-regenerable units.
