15. Slow sand filter design - Loughborough University

The size of a slow sand filter is determined by several factors. For example: Population of 1000 with water consumption of 100 litres/capita day. Wastage can be assumed to be 30 per cent of production. Therefore – total dally production needs to be: 1000 × 100 × 100 = 143 000 litres/day (100 - 30)=143 m³/day

Slow-sand water filter: Design, implementation ...

01.07.2012  A uniformity coefficient of 1 indicates all the particles are the same size. As the number increases in size, the differentiation becomes greater and the quality of the sand becomes less desirable for use in a slow-sand filter . The sand particles must be very similar in size in order to maximize the effectiveness of the filter. If there is great variability in the sizes in the

Design of Slow Sand Filter Technology for Rural Water ...

urban areas. Slow sand filtration involves the use of beds of sand for the filtration of water. The reason for designing slow sand filter for rural water treatment is to make treatment of water easy and qualitative. This research involves the use of three tanks, filter beds, filter media and filtrate tanks. Raw water is filtered by the layers of different sand particles, and conveyed by pipe after

Slow Sand Filters - SSWM

A slow sand filter (SSF) is a means of treating water for drinking water purposes and involves filtering water through a bed of ‘media’ (usually sand). It is simple in design, construction and operation. It consists of a tank inside of which lies a ‘bed’ of sand (i.e. media), supported by gravel, lying on a suitable

15. Slow sand filter design - Loughborough University

Sand Filter Design Slow sand filtration is a simple and effective technique for purifying surface water. It will remove practically all the turbidity from water, together with virtually all harmful eggs, protozoa, bacteria and viruses without the addition of chemicals and may frequently be constructed largely with local materials. A slow sand filter consists basically of three different
