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 […]

Introduction In municipal water distribution and wastewater treatment, the isolation valve is the most critical yet frequently overlooked asset. Industry data suggests that up to 20% of installed gate valves in North America are inoperable or pass water when isolation is attempted during an emergency. For the consulting engineer or utility director, the choice of […]
