Dosing pumps for water deferrization
Dosing pumps for water deferrization
- Dosage of oxidants
- Dosage of sodium hypochlorite (NaCl)
Sodium hypochlorite effectively disinfects water. Being unstable in a solid state, it is stored and transported in the form of an aqueous solution, and dosing pumps are used for dosing it. Sodium hypochlorite is used for water treatment in centralized and autonomous water supply systems.
For dosing sodium hypochlorite, membrane, peristaltic, plunger pumps are used.
The use of reagent deferrization of water based on the dosage of oxidants (sodium hypochlorite (NaCl)).
Installation components:
- Dispenser pumpDLX VFT /MBB 1-15
- Reagent container V=60L.
- Impulse flow meter 3/4 "
- Sediment filter:
- filter housing;
- Control block;
- filter material; - Carbon filter:
- filter housing;
- Control block;
- filter material (coconut activated carbon)
An oxidizing agent is dosed into the outgoing water flow (the dose is calculated on the basis of water analysis) usingmetering pump DLX VFT /MBB 0115, the signal to turn on the dispenser comes from a 3/4 "impulse flow meter installed after the filters. Treatment of water with oxidants leads to the decomposition of organic complexes, oxidation of manganese and iron and intensive coagulation of oxidized compounds. In addition, oxidants disinfect water.
Further, all oxidized elements are deposited on a sediment filter (the principle of operation is reagent-free deferrization). Since it is difficult to calculate the exact dosage of oxidants (depending on water consumption and seasonal fluctuations in water indicators), at the last stage, a carbon filter is used to delay the residual concentrations of oxidants.
As filtering materials, activated carbon obtained from coconut shells is used, which provides the following characteristics: mechanical strength, large internal surface area, the ratio of transport and working (macro-, meso- and micro) pores, the amount of adsorption.
The regeneration mode of the charcoal filter is automatic. At the moment of fluffing (backwashing), accumulated impurities are washed into the drainage.
