Slow sand filter design calculation
WebbSlow sand filtration is a type of centralised or semi-centralised water purification system. A well-designed and properly maintained slow sand filter (SSF) effectively removes … WebbOne of the oldest methods of water treatment is slow sand filtration (SSF) also known as biological sand filtration (BSF). The method is adapted from nature’s own way of treating water by filtration and has been used artificially by humans since the beginning of the nineteenth century.
