Tackling Water Hardness: Understanding the Issue for Sustainable Development
Abstract: Hard water poses a serious threat to human health and industrial operations. The pervasiveness of water hardness, characterized by elevated concentrations of calcium and magnesium ions, originates from seepage and runoff from soils, as well as polyvalent metallic ions from sedimentary rocks. These minerals, while essential in moderate amounts, can become problematic when consumed in excess. Epidemiological studies have established correlations between excessive consumption of calcium and magnesium and increased …

Parametric Studies of In-house Resin for Hardness Removal
Abstract: Presence of high amount of calcium and/or magnesium makes the water hard as these ions in water react with other chemical agents and constituents of metallic plumbing etc. The process accelerates in the presence of heat. It decreases the efficiency of the unit operation due to the formation of scales. Hence, scaling is the main issue for which hard water is required to be treated or polished. De-mineralized water finds …
