The issues of technological modeling of physicochemical iron removal from deep groundwater at the rapid filter

Abstract An exact solution to the task of physicochemical iron removal from natural water containing excess iron ferric form at the rapid filters is presented in the article. The principles of applied optimization of filters for iron removal are formulated based on technical and economic calculations. Three filter control algorithms are described and technological modeling of its operation is performed throughout the service life of the filter medium when implementing a regular algorithm. The impact of the main design parameter on the economic indicators and, first of all, the reduced costs is analyzed. The possibility of minimizing the cost of water treatment through a reasonable choice of the packed bed height has been demonstrated.
