Introduction In the design of municipal water treatment plants and industrial wastewater facilities, the butterfly valve is often treated as a commodity item. This assumption—that “a valve is just a valve”—is a primary driver of unexpected operational expenditure (OPEX) and premature system failure. Engineers frequently encounter scenarios where a valve specified for general isolation fails […]

Introduction Ion exchange (IX) remains one of the most versatile and critical unit processes in water treatment, yet it is frequently the source of significant operational expenditure (OPEX) overruns due to improper specification. Engineers often face a dichotomy: simple softening applications are treated as commodities, leading to premature vessel failure or inefficient salt usage, while […]
