Arionex IX | Arionex Water Treatment

Purpose

Arionex IX unit is designed for elimination of various chemical elements and organic compounds from the water.

Application fields

Softening

Purpose – elimination of water hardness salts (Ca and Mg). Strong acid cation ion-exchange resin is used. The water is filtered through the resin where Ca and Mg ions are replaced by Na ions during the process. The resin is regenerated with NaCl or KCl solution when exhausted. It is used in industrial water treatment for use in industrial processes.


Quality of supplied water	Surface (processed by ultrafiltration membranes), municipal, deep waters – without iron, manganese hardness ions (or treated with reagents)
Hardness of treated water	0.02 mg-ekv/l (meq/l) or 0.005 mg-ekv/l (meq/l) – using a packed-bed counterflow regeneration technology. In case of lower quality requirements, water quality is adjusted by dilution/mixing method.
Capacity of the standard softening filter unit	1 m3/h – 200m3/h. *capacity of the designed system is not limited

Demineralization

Purpose – demineralization of the water. Strong/weak acid cation ion-exchange resins and strong/weak base anion ion-exchange resins are used. The water is filtered through the cation ion-exchange resin where the cations are replaced by H ions, and then the water is filtered through the anion ion-exchange resin where anions are replaced by OH ions during the process. The cation resin is regenerated with HCl or H2SO4 acid solution, the anion resin is regenerated with NaOH alkaline solution when exhausted. The most efficient packed-bed counterflow regeneration technology is used. It is used in industrial water treatment for use in industrial processes.


Quality of supplied water	Surface (treated by clarification or by ultrafiltration membranes), municipal, deep waters
Conductivity of treated water	up to 2.5 µS/cm
Capacity of technologic line unit	5 m3/h – 250m3/h. *capacity of the designed system is not limited

Organics elimination

Purpose – elimination of the organic compounds from the water. Anion ion-exchange resin is used. The water is filtered through the resin where organic compounds are removed by adsorption/ion exchange principle during the process. The resin is regenerated with NaCl or NaOH solution when exhausted. It is used in industrial water treatment for use in industrial processes.


Quality of supplied water	Surface (treated by clarification or by ultrafiltration membranes), municipal, deep waters – without iron, manganese hardness ions
Capacity of the standard softening filter unit	1 m3/h – 50 m3/h *capacity of the designed system is not limited

Boron elimination

Purpose – elimination of the boron compounds from the water. Anion ion-exchange resin is used. The water is filtered through the resin where boron compounds are removed by ion exchange principle during the process. The resin is regenerated with NaCl , HCl, NaOH solutions when exhausted. It is used in drinking-water treatment.


Quality of supplied water	Desalinated sea water, deep water – without iron, manganese ions
Capacity of standard boron elimination filter unit	1 m3/h – 50 m3/h *capacity of the designed system is not limited

Alkalinity reduction

Purpose – reduction of alkalinity (CaHCO3, MgHCO3). Weak acid cation ion-exchange resin is used. The water is filtered through the resin where Ca and Mg ions are replaced by H ions during the process. Carbon dioxide is released during the reaction which is eliminated by degasifying unit. The resin is regenerated with HCl or H2SO4 solutions when exhausted. It is used in industrial water treatment for use in industrial processes, often used in beer production.


Quality of supplied water	Surface (treated by clarification or processed by ultrafiltration membranes), municipal, deep waters – without iron, manganese hardness ions
Alkalinity of treated water	0 – 2 mg-ekv/l (meq/l)
Capacity of standard decarbonisation filter unit	1 m3/h – 150 m3/h *capacity of the designed system is not limited

Demineralization with Arionex IX Multrex

Purpose – demineralization of the water. Strong/weak acid cation ion-exchange resins and strong/weak base anion ion-exchange resins are used. The water is filtered through the cation ion-exchange resin where the cations are replaced by H ions, and then the water is filtered through the anion ion-exchange resin where anions are replaced by OH ions during the process. Polishing of the water is done using cation ion-exchange resin in special construction filter, with external or internal regeneration. The cation resin is regenerated with HCl or H2SO4 acid solution, the anion resin is regenerated with NaOH alkaline solution when exhausted. The most efficient packed-bed counterflow regeneration technology is used. All technological line could be installed in one multi chamber filter or in several two chamber filters. It is used in industrial water treatment for use in industrial processes.


Quality of supplied water	Surface (treated by clarification or by ultrafiltration membranes), municipal, deep waters
Conductivity of treated water	less than 0.07 µS/cm
Capacity of technologic line unit	5 m3/h – 250m3/h. *capacity of the designed system is not limited

Polishing with Arionex IX Mixcat

Purpose – polishing of demineralized water. Strong/weak acid cation ion-exchange resins and strong/weak base anion ion-exchange resins are used. The water is filtered through the mixed cation and anion resin bed where the cations are replaced by H ions, and anions are replaced by OH ions during the process. When resin is exhausted, cation resin is separated from anion resin and regenerated internally in the filter. The cation resin is regenerated with HCl or H2SO4 acid solution, the anion exchange resin is regenerated with NaOH alkaline solution. The high quality of treated water is guaranteed by using filter of specific design which helps to avoid resin cross-contamination with regenerants. It is used in industrial water treatment for use in industrial processes.


Quality of supplied water	Demineralized water or condensate, electric conductivity 40 µS/cm
Conductivity of treated water	up to 0.056 – 0.1 µS/cm
Capacity of technologic line unit	1 m3/h – 200m3/h. *capacity of the designed system is not limited
