Abstract: 

The nonlinear problem of transfer and deposition of ferric iron in the bed layer of a fast filter is posed with regard for the oxidation of ferrous iron and is strictly solved. We have constructed relations and equations for the
calculation of an increase in the head loss in the bed, as well as changes in the concentrations of suspended and deposited particles of Fe hydroxide in time and along the bed height. By examples, we forecast a growth in the content of Fe hydroxide in the filtrate and deposited form. The possibility of a reliable substantiation of technological and constructional parameters on the basis of the obtained solution is discussed.

Keywords: clarification, concentration, deposition, hydroxide, iron, oxidation, rigorous solution, transfer
