Abstract
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.
期刊介绍：
Scientific Review Engineering and Environmental Sciences [Przegląd Naukowy Inżynieria i Kształtowanie Środowiska] covers broad area of knowledge and practice on fields such as: sustainable development, landscaping of non-urbanized lands, environmental engineering, construction projects engineering land management, protection and land reclamation, environmental impact of investments, ecology, hydrology and water management, ground-water monitoring and restoration, geotechnical engineering, meteorology and connecting subjects. Authors are welcome to submit theoretical and practice-oriented papers containing detailed case studies within above mentioned disciplines. However, theoretical papers should contain part with practical application of the theory presented. Papers (in Polish or English languages) are accepted for publication after obtaining positive opinions of two reviewers. Papers published elsewhere are not accepted.
