slow sand process flow diagram

During normal production, operate slow sand filters continuously, without stopping or interrupting the filter effluent flow. If you need to change the filter flow rate, make the change gradually so that previously captured particles remain trapped in the sand. Set the filter flow controls to accommodate anticipated changes in system demand.

A Process Flow Diagram (PFD) is a type of flowchart that illustrates the relationships between major components at an industrial plant. Its most often used in chemical engineering and process engineering, though its concepts are sometimes applied to other processes as well. Its used to document a process, improve a process or model a new one. The flow speed is determined by the desired end result. Slow sand filters have a surface load of 0.1-0.2 m/m/hour. Continuous sand filters have a hydraulic speed of 5-10 m 3 /m 2 /hour. Effectiveness. Sand filtration is primarily used for the removal of suspended matter.
