The In-line Aeration System from Mazzei Injector Company provides a maximum transfer of oxygen with low energy usage and minimum operator involvement and maintenance, especially in pressurized systems. With no moving parts, it’s a solution that offers trouble-free operation in a small footprint. A sidestream is taken off an effluent pipeline, directed through a booster pump, and then through Venturi injectors to mix atmospheric air or oxygen with the water. The aerated sidestream is then mixed back into the effluent pipeline through a Pipeline Flash Reactor for greater oxygen transfer and mixing in order to reach dissolved oxygen limits before being discharged into receiving waters. 661/363-6500; www.mazzei.net
