Abstract
The invention relates to the water treatment, particularly to reagent multistep filtering through granular loadings and can be used in water treatment for potable and technical purposes, and also for the advanced treatment of waste water. The aim is the possibility of quick response to the change of the composition of influent water by means of regime adjustment of its reagent treatment, obtaining of high quality of treated water, increasing of duration of filter cycle, economy of the rinse water and increasing of useful output of treating plant.The process for reagent water treatment is proposed, by which a regime for rearrangement of parts of optimal dose of coagulant between separate filter stages is determined expressively by construction of influence curves of filtrate quality from introduced before filters parts of doses. The implementation of the process allows increasing the operation time of filters between washings in 1.5 times, decreasing of expenditure of the rinse water and therefore to increase the productivity of the plant in 1.07-1.1 times.
