Slow Sand Filtration

May 21, 2019Hence, slow sand filtration is a promising filtration method for small to medium-sized, rural communities with a fairly good quality of the initial surface water source. As stated by the WHO, slow sand filtration provides a simple but highly effective and considerably cheap tool that can contribute to a sustainable water management system.Get more +

Design criteria for filtration

Pre-treatment of runoff in a sand filter system must be provided. Inlets to surface sand filters must be provided with energy dissipaters. Exit velocities from the pretreatment device must be non-erosive. An emergency or bypass spillway must be included in the surface sand filter to safely pass flows that exceed the design storm flows.Get more +


filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration. The coarser sand in the rapid filters has larger voids that do not fill as easily.Get more +

Design of a Filtration System for a Small Scale Water

Design of a Filtration System for a Small Scale Filter sand has a grain size of 0.4-1.0mm which is large in comparison with many of the smaller particles carried by water and the rapid gravity sand filter can only operate as intended when coagulants have been used. Interception of the suspended matter by the sand is a fairly complex process Get more +

Slow Sand Filtration

Users can maintain flow rate by cleaning the filter through agitating the top level of sand, or by pre-treating turbid water before filtration. Lab Effectiveness, Field Effectiveness, and Health Impact. Slow sand filter lab effectiveness studies with a mature biolayer have shown 99.98% protozoan, 90-99% bacterial, and variable viral reduction.Get more +

Design Examples

Rapid Sand Filter Design. Problem: Design a rapid sand filter to treat 10 million litres of raw water per day allowing 0.5% of filtered water for backwashing. Half hour per day is used for bakwashing. Assume necessary data. Solution: Total filtered water = 10.05 x 24 x 10 6 = 0.42766 Ml / h 24 x 23.5. Let the rate of filtration be 5000 l / h / m 2 of bed.
