Abstrakty

An approximate solution to the system of equations governing the flow distribution among variable declining rate (VDR) filters results in flow rates through filters being elements of a geometrical progression. Based on this approximation, it was deduced how to operate a plant in order to keep the same flow rates through VDR filters for various total head losses of flow. These principles of operation were carefully verified using the accurate di Bernardo mathematical model of VDR filter plants. It was deduced that the longest filter runs result from such an operation of a plant for which the ratio of the highest to the average flow rates through a filter and simultaneously the affordable total head loss of flow through the plant are the highest.
