What is ProMix?
Conventional systems inject sterilizing agents or flocculants using fixed-volume or simple proportional control. However, fluctuating raw water quality and pump conditions constantly alter the actual chemical demand, exceeding the capabilities of traditional fixed or single-variable injection setups.
Tohkemy’s ProMix system overcomes these limitations by integrating secondary control triggers—such as turbidity—alongside primary flow metrics. This multi-variable strategy enables precise, dynamic chemical dosing that adapts continuously to real-time water conditions.
Excellent operability with touch panel type

Flow rate proportional + linearize
You can select from the above four types of control methods, and optimal control is possible for your application.
Supports remote input of control target values
Even if the target value changes due to process steps, etc., the target value can be changed with the 4-20mA DC analog signal on the upper board.
Application example
PAC chemical injection control for filtration of river water and shallow wells
Control of pH regulator drug injection for applications with large flow rate fluctuations
Hypochlorite injection control for large applications with variable flow rates

Flow rate proportional + feed forward or PID feedback (type E)

<Flow rate proportional + feed forward>
The water quality is measured before the chemical injection point, _and the difference from the target value is the chemical injection.
Example) If the water quality concentration in the previous stage is 0.3 mg / L _and the target value is 0.5 mg / L, perform drug injection at 0.2 mg / L (× correction coefficient).<Flow rate proportional + PID feedback>
The water quality is measured after the drug injection point, _and the drug injection rate is controlled to approach the target value while changing it by proportional control or PID control compared to the target value.
Linearize control (type D)
<Linearize control>
An injection method that changes the injection rate in a line graph rather than simply changing the injection rate proportionally according to the water quality value.

Like the TPC type, this type continuously neutralizes raw water while discharging it. Carbon dioxide gas is used as a neutralizing agent. It reacts quickly and mixes easily, so the residence time in the neutralizing tank can be shorten and the installation area can be made smaller. In addition, even if an excessive amount of carbon dioxide gas is injected, the pH value will not drop below pH5.
Therefore, it is possible to prevent the pH value from dropping too low. The standard treatment range is pH7 to 11.
*Neutralization reactions may require more chemicals than the calculated value due to factors that inhibit the reaction of chemicals.
