Aquionics, of Erlanger, Ky., introduces closed-vessel inline UV disinfection systems that utilize high intensity, medium-pressure lamps for disinfecting primary, secondary or tertiary treated wastewater or industrial effluent to the required discharge limit. The disinfection chambers are compact, installed directly into existing pipework, designed for gravity-fed or pumped applications, and provide minimal headloss. As a result, the company can provide treatment with significantly smaller footprint vs. an open-channel configuration.
