Chemical dosing is a common process in most water treatment systems. Dose is always dependent on water quality and flow rate through the system. Besides, other parameters such as water turbidity, PH or ORP level will define adjustments required to control the dosing amount.
The dosing pumps are self-priming diaphragm pump with stepper motor and electronic control to deliver excellent dosing features:
  • Continuous dosing
  • High accuracy
When source water quality is consistent with time, dosing adjustment can be carried out manually, but in those cases when feedwater characteristics have a certain variability an automated control will be the preferred option.
When an automated control is chosen, the chemical injection can be controlled by a single parameter such as flow rate, or ir can be controlled by two or more criterion like flow and PH.
Most Watercore projects relay on piston or diaphragm dosing pumps and the selection will be based on the maximum output pressure and required dosing capacity.
At Watercore, we are experts at ensuring that you choose the right dosing system for your application. Above all, our range of commercial and industrial dosing solutions will adapt to the water treatment process.
