Optymalizacja parametrów technologicznych filtra z granulowanym złożem polistyrenowym do uzdatniania wody kotłowej (studium przypadku)

The article presents research to determine the optimal technological parameters of the hot water pre-treatment filter for the analyzed boiler water cycle. For the analyzed case, the optimal parameters are: the grain size of the polystyrene bed d = 1.25 mm, the filtration speed V = 7.0 m·h–1, the height of the filtration layer H = 1.2 m. The use of a polystyrene filter bed allows obtaining comparable efficiency of water treatment in relation to the traditionally used quartz sand. Analysis of the kinetics of pollution removal showed that during filtration of water through the polystyrene bed in the direction from the bottom up there are two zones: the lower zone is dominated by the process of mechanical deposition of oxidized iron, the upper by reduction of the COD concentration.
