The unevenness of water distribution in collection and distribution systems
Journal Title: Вісник Одеської державної академії будівництва та архітектури - Year 2017, Vol 1, Issue 68
Abstract
The article examines the reasons for the unevenness of water distribution in collection and distribution systems of water purification facilities, its impact on the quality of the treated water and the processes taking place in water treatment facilities during their operation. It also provides methods for evaluating the uneven distribution of flow and ways to reduce the unevenness arising in the pressures field and uneven resistances for collection and distribution pipelines with discrete and continuous flow distribution. Based on the analysis of existing methods of reducing unevenness, it was determined that it is possible to reduce the impact of the unevenness in the pressures field for collection and distribution systems with discrete flow distribution by applying distributing pipes with variable cross-section, pitch or diameter of perforation. Reducing the impact of such unevenness for collection and distribution pipelines with continuous flow distribution can be achieved by using distributing pipes with variable cross-section along its length. In calculating water collection and distribution systems, unevenness resistances caused by failures of manufacture and assembly of drainage system can be considered using the Кδ and С coefficients given in this article.
