Stan Hazan comments on the International Symposium on Health Aspects of Calcium and Magnesium in Drinking Water
Interview with Joseph F. Harrison, P.E., CWS-VI, technical director of the WQA, on the calcium and magnesium issue and the possible impact on the water treatment industry
More than 162 participants from 25 countries attended the symposium on Health Aspects of Calcium and Magnesium in Drinking Water held April 24 to 26, in Baltimore. The symposium was organized by NSF International, the NSF/WHO Collaborating Centre for Drinking Water and the International Life Sciences Institute.
Stan Hazan, senior director of regulatory affairs for NSF, told Water Quality Products the goal of the symposium was to review epidemiological and other health-based information on the potential benefits of magnesium and calcium in drinking water.

WQP observes the ins and outs of a residential softener installation
Pressure vessels have made their mark on the water treatment industry. From residential treatment systems to commercial systems, pressure vessels are used in water softeners, filters and RO systems. Pressure vessel size and capacity correspond to the application, generally less than 120-gal. capacity in residential applications. Commercial applications require various capacities up to 2,000 gal.
Although pressure vessels once installed require little maintenance, proper care must be taken at the receiving, handling and installation stages to avoid damage or failure.
