FIELD: chemistry; water treatment. ^ SUBSTANCE: present invention can be used in housing construction and in industrial water treatment systems. The water treatment system consists of reservoirs 1, for filter loads (tanks), commutator units 2, reclamation unit 3, reagent containers 4, control unit 5, connection pipes 6 and two-way flow switches. Commutator units 2 and reclamation unit 3 are joined to a bus with three channels 7, 8 and 9. The reclamation unit 3, comprises a unit for changing flow direction, unit for initiating feeding of reagent, device for feeding reagent, for example, injectors or pumps, a switch for filling reagent container 4 with water, switches for selecting reagent and switches for limiting flow. Commutator units 2 correspond to reservoirs 1 and each of them has units for switching the inlet and outlet of the reservoir from connection with other reservoirs to connection with the reclamation unit 3, as well as a switch for feeding water into the reclamation unit 3. The given hydraulic modules join two-way flow switches on the principle of synchronised switching from one position to another. ^ EFFECT: invention enables, for each reservoir, realisation of all possible versions of the operational process and reclamation, connect them in any arrangement (serial, parallel, combined) and provides for flexible readjustment. ^ 4 dwg |
