WTD designs and supplies an extensive range of systems using Ion Exchange Technologies for production of Demineralized Water
In accordance to desired outlet water characteristics: softening, silica removal, general demineralization, condensate polishing, ultrapure water production, metals removal, etc.
According to target performance, specific process can be selected, involving use of strong or weak resins, adsorbent type or chelating resins for higher selectivity, etc.
Electrodeionization is also considered to achieve ultrapure water requirements.
Each ion exchange unit delivered by WTD has a tailored configuration addressed to the specific result to be obtained.
Anionic/Cationic exchangers might be integrated with Mixed Bed vessels and degasifying systems for CO2 removal; Condensate polishing units are supplied for high pressure steam generation.
Various operational modes are possible such as upflow/downflow, packed beds, internal / external regeneration systems, resin washing facility, etc.
Properly designed pre-treatment of feed water is of fundamental importance for not harming resins performance and durability, given their cost. Filters with different media, coalescers, etc. may be involved.
Our demineralization plants are supplied with PLC based system for controlling all operating parameters and automatic regeneration.
WTD typically includes regeneration chemical dosing units and complete facilities for regeneration
include heavy metals recovery, colour removal, arsenic reduction for potabilization purposes, etc.contactS
