Oxidation-Ditch Process Using Falling Water as Aerator
Publication: Journal of Environmental Engineering
Volume 121, Issue 2
Abstract
This paper examines the use of falling water as an aerator for the oxidation-ditch process. The study was carried out in order to clarify the characteristics of this process and compare it with other oxidation-ditch processes. The method uses pumps that lift wastewater and cause it to develop a head, creating a cascade or waterfall. Application of this concept may reduce construction costs for wastewater treatment plants. Furthermore, nitrogen removal is made easier through simple control of pump speed, on-off functions, and change in the height of the waterfall. Aeration efficiency is similar to that of aerators used in other oxidation-ditch processes. The power input of this oxidation-ditch-aeration process was the lowest of all the oxidation-ditch processes. This oxidation-ditch process also provides various other advantages for waste-treatment plants.
