Water Softener vs. Condensate Polisher – Knowing the Differences Can Help you “Get Greener” >

Many companies are on a constant quest to run their business in the most energy-conscious, money-saving way possible. For those whose operations involve a low-pressure boiler system environment, investing in a condensate polisher is one of the easiest ways to “get greener” through energy efficiency and dollar savings. In most every boiler plant, cold water


Q&A on Condensate Polishers with Res-Kem’s Kevin Preising >

While dirty condensate clean-up can be an energy buster in most processing plants, one cost effective solution is to polish contaminated condensate for re-use. Condensate polishers use a simple ion exchange technology that is easy to operate, easy to maintain and economical to use – less make-up water is required which leads to lower chemical

Resin Traps-Insurance for Industrial Water Systems >

Recently, Res-Kem published a white paper entitled “Inexpensive Insurance for Water Treatment Systems-Resin Traps” by Ron Madden. In this white paper, three examples demonstrate how resin traps act as inexpensive insurance for costly problems that can develop when ion exchange resin reaches downstream process areas, process equipment, or the product. Depending upon the plant or


Water Analysis Article >

I came across an excellent article in an old issue of Water Conditioning & Purification magazine entitled “Making Sense of an Incomplete Water Analysis” by Frank DeSilva of ResinTech Inc. This article defines what the minimum required water analyses are for: Cationic Applications (hardness removal, metals removal, radium removal) Anionic Applications (sulfate removal, nitrate removal,
