Chemical Dosing (CD)

MAK Water’s Chemical Dosing (CD) skids are designed to automatically dose a chemical(s) into a pressurised pipeline. The package includes an inline sensor(s) (pH, ORP or free Chlorine analyser) which monitors the desired output target.

When flow is detected in the pipeline, the dosing pump(s) is called online; the controller automatically adjusts the dosing pump(s) to dose the desired chemical. Up to three chemical dosing stations are available.

The system components are sized to suit the raw water flow rate and daily usage. Optional equipment upgrades include; a flow transmitter, a static mixer if required to improve mixing, duty standby dosing pumps, dual chemical dosing pumps (alkali/acid). MAK CD plants are available as skid mounted or containerised systems for easy deployment to remote locations.
