Introduction In the high-stakes environment of municipal and industrial wastewater treatment, few decisions impact long-term operational costs (OPEX) as significantly as the selection of oxidation and gas handling systems. Engineers frequently underestimate the lifecycle implications of dielectric technologies and cooling requirements when specifying ozone generation systems for disinfection, micropollutant removal, or sludge handling. A specification […]
