Water quality produced by polystyrene granules as a media filter on rapid filters

A simulation study of surface water purifying through a polystyrene foam filter

“…The problems of research [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] on water filtration can be divided into several directions.…”

“…M a r t y n o v distribution of pollution in terms of the loading height and lower pressure losses. Another area of research to improve the efficiency of water purification by granular filters is the search for materials with high porosity and specific surface [9,12,13].…”

“…The type of filter loading, the grain parameters and the height of the loaded layer greatly affect the efficiency of water purification, the size of the filter plants and their performance [6][7][8][9][10][11][12][13].…”

“…One of the economically feasible loads is a floating material, in particular, polystyrene foam, which has a number of technical and economic advantages, compared to other materials [7,10,12].…”

“…Filters with expanded polystyrene loading, which were first proposed to be used for water purification at the Department of Water Supply and Drilling, Ukrainian Institute of Water Economy Engineers (now National University of Water Management and Nature Resources Use), are widely employed worldwide [4,12,13]. In this regard, for a reasonable choice of optimal structural and technological indicators of work, there is a need to develop a mathematical model that would take into account the peculiarities of such filters' operation.…”
