Regulating bubble size and durability with Membranes

Aeration is a part of almost every wastewater treatment plant, but cheap products and unreliable suppliers have made life difficult for operators and engineers.

EDI supplies aeration for lIfe™ meaning we support engineers from the first design, contractors with the easiest installation processes, and plant operators with the widest range of American-made aftermarket parts, so treatment plants can trust its aeration again.

EDI has been revolutionizing wastewater aeration since 1975, and we are only getting started. We are relentlessly focused on making cutting-edge aeration easy for engineers to integrate, simple for operators to maintain, with a total lifecycle cost that makes it easy for municipalities or industrial clients to manage their environmental impact.
