Prevent the growth of germs in water softeners, without heat

Water softeners are needed in pretreatment stages for pure-water generators, but they also harbor risks: the ionic-exchange resins offer large surface areas for the growth of microorganisms. A safe and simple solution to this problem is the germ-reducing regeneration tablets, Sanisal P (photo). The tablets are poured into the salt or brine tank of water softener, and its active substance is released, entering the water softener during regeneration. Dead germs and any residue are then flushed out of the softener during the rinse stages. Regeneration salts are no longer needed, and, in contrast to hot-water sanitation, no energy is required. — Christ Water Technology Group, Aesch, Switzerland

Corrosives are not a problem for this plastic strainer

Basket strainers made of Kynar polyvinylidene (PVDF) are now available exclusively from this firm. Plastic strainers previously available were not able to handle corrosive materials, such as halogens and many acids, or temperatures exceeding 220°C. PVDF far outperforms polyvinylchlorides (PVC and cPVC), polypropylene and acetal materials, says the firm. With higher capacity than Y-strainers, these units capture substantial solids, thereby extending the life of expensive downstream equipment. Sizes from 1/2 to 3 in., with a wide variety of connections and mesh screens are available. — Micromold Products, Inc., Yonkers, N.Y.
