Mazzei Aeration Systems for Post-Treatment Aeration

Post-Treatment Aeration

Many wineries discharge their treated water into public waterways. Current or future permits require minimum dissolved oxygen levels in the discharge water to be 5-7 mg/l. The Mazzei AirJection^® Aeration Process is ideal for introducing air or oxygen into effluent basins or piping. Treated effluent is pumped from an effluent basin or directly from the effluent piping through Mazzei^® Venturi injector(s) which aspirate either air or concentrated oxygen without the need for blowers and compressors. The concentrated oxygen source can be LOX or a PSA type concentrator. The resulting effluent and air/oxygen mixture is then discharged back into the effluent basin or piping through Mazzei MTM™ mixing nozzles which thoroughly mix the sidestream with the main effluent flow.
