Custom, integrated deionized water systems for your water needs.
Deionization is one of the most efficient processes known for removing ionic dissolved salts and minerals from water. The deionization process is the the removal of all charged ions from the water. The term demineralization is also commonly used to describe this process.
Two Bed Deionized Water Systems
Separate bed deionizers can have a higher exchange capacity and less complicated operating procedure than mixed bed systems. In a dual bed deionizer, the cation and anion exchangers are connected in series. The cation tank removes positively charged ions (calcium, sodium, magnesium, iron, manganese and potassium). The anion tank removes negatively charged ions (sulfates, chlorides, carbonates, bicarbonates, nitrates and silica). Strong base anion units typically produce 0.2 megohm water at a pH of 8-9, whereas weak base anion units produce lower water quality, a pH of 6-7, and do not remove silica or CO2.
Mixed Bed Deionized Water Systems
Mixed bed deionizers can have a higher water quality, lower rinse water requirements, and more neutral pH than dual bed systems. In a mixed bed deionizer, cation and anion resins are combined and mixed in a single tank. Thousands of cation and anion ion exchanges take place as water passes through the resin bed. Typical water quality of 2 megohm or more with neutral pH.
Multiple Tank Deionized Water Systems
Three tanks or more are connected in series; or parallel; or a combination of the two. Produces high purity water in any desired quantity. Systems may consist of strong acid cation, strong or weak base anion and mixed bed media tanks in a number of varying combinations, to produce the water quality required. Water qualities of 15 megohm or more, with a neutral pH, can typically be attained.
Complete Multiple-Process Treatment Systems
Exchange service tanks using other water treatment media create a more complete high purity water system. Typically, a system may include one or more of the following processes: softening, depth filtration, carbon adsorption, UV sterilization, submicron filtration, or other treatment equipment.
