Designing A Continuous Sand Filter

Sand Filter an overview ScienceDirect Topics

26.3.3.1 Continuous Sand Filter. Continuous sand filters (see Fig. 26.6) are gravity-driven depth filters with countercurrent flows of filter sand and dirty fluid.Dirty fluid is introduced into the bottom of the structure, and clean fluid is collected at the top.

Sand cleaning is continuous while the filter is in operation and hence a 24/7 availability of the process is guaranteed. The process features, advantages and applications of MBF are presented below. Three applications of MBF are discussed in more detail on the following subpages: biological (de)nitrification and wash waster treatment.

Sand filter Wikipedia

Sand filters are used as a step in the water treatment process of water purification.. There are three main types; rapid (gravity) sand filters, upward flow sand filters and slow sand filters.All three methods are used extensively in the water industry throughout the world. The first two require the use of flocculant chemicals to work effectively while slow sand filters can produce very high
