System complete set:
- filter column (material - fiberglass reinforced with food-grade inner surface, no seams);
- loading (filter material and gravel);
- distribution system;
- control mechanism;
- proportional dosing complex (input injector, impulse water flow meter, flexible delivery tube, mixer, dosing pump, reagent tank, suction unit).
Operating principle:
Reagent removal of dissolved iron, manganese and hydrogen sulfide from water occurs in pressure filter columns.
Usually MGS or MTM is used as filter material. Manganese oxide is an oxidizing agent for iron, manganese and hydrogen sulfide. Iron removal and / or demanganation processes are processes that lead to the fact that iron or manganese dissolved in water transforms into an insoluble form and precipitates.
During the operation of the system, the catalytic activity of the filter material decreases. The main feature of the TKAMG series systems is that the regeneration of the filter material occurs during the operation of the system. The oxidation of iron, manganese and hydrogen sulfide in the columns and the maintenance of the filter material (MGS or MTM) in working order is created by continuously introducing an oxidizing agent (potassium permanganate solution) into the water in front of the filter columns using a dosing complex.
The system is ready for operation all the time, except for a short time interval, which is necessary for flushing the filter material with water from contamination (20 - 25 minutes).
Flushing includes two stages:
- backwash (backwash),
- fast rinse (rapid rinse),
The wash water is discharged into the sewer during the regeneration process. After the completion of the regeneration, the system is put into operating mode (filtration mode).
Service flow - depending on the technical task.
