The FlexDome™ series of Fine Bubble Diffusers from EVOQUA employs a unique bolt design that allows the ceramic dome to be adjusted without affecting the entire piping system. Th smooth outer surface guarantees less maintenance and downtime, and material build up is decreased by the even bubble distribution. A guaranteed 25 - 40 % cut on an operator's costs may be provided by the FlexDome. This comes with increased oxygen transfer that is sustained on a long term period.
