  • Management and design implications of a mathematical model

    ·

    A model has been proposed and tested describing the removal of water from the bed surface of a rapid gravity sand filter during a backwash. The model can be used in design to predict the minimum height of the weir above the expanded bed required to prevent media loss and also the minimum length of time for a backwash to obtain a clean bed.

  • Rapid Sand Filtration | SSWM Find tools for sustainable

    Rapid sand filtration is a purely physical drinking water purification method. Rapid sand filters provide rapid and efficient removal of relatively large suspended particles. Two types of RSF are typically used: rapid gravity and rapid pressure sand filters. For the provision of safe drinking water, RSFs require adequate pre-treatment (usually coagulation-flocculation) and post-treatment (usually disinfection with …
