Membranes: TOC reduction using membrane technology

Honeywell’s Solid State Electronics Centre (SSEC) in Plymouth, Minn., had been trying to reduce the level of total organic carbon (100) in its high-purity deionized water system for many years. They had always experienced periods of relatively low 100 (less than 10 parts-perbillion [ppb]) but always had periods of high 100 (greater than 50 ppb). These high periods had usually been short periods ...

Optimized water softening systems thanks to quality-controlled regeneration

Novel water hardness monitoring For the production of soft water, ion exchange units with sodium chloride regeneration have been increasingly used for more than 50 years. The course and dynamics of the softening process depend on the ion exchange resins used, the proper regeneration processes, the removal quantities and their dynamics. These processes do not run constantly in practice, which is ...
