THEORETICAL APPROACH OF WATER HAMMER EFFECT ON THE EFFICIENCY OF FILTER ELEMENT DURING THE FILTRATION OF WATER

Abstract

The purpose of the present study is to examine the effect of water hammer phenomenon within water flow pipeline, on the efficiency that a filter element will have in the process of water filtration, as long as this element is situated in the pipeline when the filtered water flows. In the study initially the necessary theoretical background will be described that is related to the basic equations governing the water hammer phenomenon, as well as the analysis of the parameters governing the mechanisms of fluid filtration through a filter element and affect its efficiency. Subsequently after the combination of equations and water hammer sizes and fluid filtration, the final equations and curves will be drawn so that will help us to describe the phenomenon of water hammer effect on the efficiency of a filter. The general conclusion which arises is that the existence of water hammer reduces the particle collection efficiency for nanofiltration, while for range of large diameters, the efficiency is not affected at all.
