Discharging chlorinated water from storage tank overflows onto land or into a stormwater system can be toxic and severely harmful to plant and aquatic life. In
order to address environmental concerns and potential regulatory penalties, Tideflex Engineers have created an overflow pipe assembly that prevents bird/rodent
intrusion, increases tank security, and also removes chlorine and chloramine residual during overflow discharges.
The Dechlorinating Overflow Security Assembly, or DOSA, is constructed of dual Tideflex Nozzles and an internal adjustable dechlorination tube completely enclosed in a powder coated steel body. During an overflow event, the upper Tideflex Nozzle discharges an elliptically-shaped jet down into a dechlorination tube. A calculated portion of water passes through the tube. The rest of the water deflects around the tube. All of the water is then blended to ensure it is thoroughly mixed and dechlorinated, prior to discharging out of the DOSA through the lower Tideflex Check Valve.
