Avoiding Hydraulic Air Locks In A Degasification Tower.

Bio3.jpgWhen designing and installing a water treatment system it is important to pay attention to the hydraulic conditions that may be created when placing a degasification or aeration tower into the process. Much like any water line design, hydraulic conditions vary from job to job and so do the conditions created by a degasification tower. Typically you will find degasification towers mounted on top of either a large storage catch tank, draining directly into the tank below, or mounted on their own pedestals with the effluent piping drops down and may enter the catch tank on the side or even from the bottom. When the effluent drain line drops straight down for any significant distance the potential of creating a “vortex” effect may occur in the water flow. In addition, the increased hydraulic flow and distance will create an increased suction on the effluent line, and in some circumstances can restrict the water flow causing flooding inside the degasification tower. A vortex is a when the water begins to swirl, draws air down the center, and begins to restrict the drainage of the tower.
To avoid these pitfalls it is important to install vortex breakers inside of degasification towers, as well as properly locate both air relief valves and anti-syphon valves along the finish effluent pipeline of treated water. For more information or to learn more contact the professionals at DeLoach Industries Inc. at (941) 371-4995.
