Current filter design and operating trends are toward higher unit filter rates and wider flow variations through filters. To prevent deterioration of effluent quality from inherent or induced surges at these higher rates, control systems must provide stable performance. The items entering into a flow control loop must be carefully selected. Manufacturers specializing in filter flow control systems have designs available that will fulfill all of the criteria mentioned in this discussion. The sand filter, rather than being an expensive adjunct to water treatment, is now resuming its proper status as an important element in the water treatment process.
