For excellent and stable suspended solids and turbidity removal performance, the feeding wastewater's pH is much important. To some wastewater, for example textile dyeing wastewater, it is commonly alkaline, acid is required to be dosed into water to adjust the water pH. While to electroplating wastewater, it is commonly acidic because of its acid pickling processing, alkali is required to be dosed into water to adjust the water pH.

According to our rich experience on different kinds of wastewater treatment projects, pH range 7.5-8.5 is much suitable and practical. While, the same with the selection of flocculant and coagulant, an accurate pH value and pH dosage should be selected and confirmed through jar tests.

Factory manufacturing process and wastewater treatment chemical dosing are both continuous, thus requiring a multi-functional dosing machine which can monitor water pH and then dose acid or alkali intelligently to adjust water pH. Our this automatic pH regulator is specially designed for these application.

The advantage you will get after installing this automatic pH regulator: Get better removal performance on suspended solids and turbidity; Greatly decrease daily cost on flocculant and coagulant.

Automatic pH regulator is mainly composed of agitator, chemical dosing tank, online pH meter, pH probe and dosing pump. A pH probe is installed in the water inlet or in the water feeding pipe. The probe detect water pH and transfer electric signal to the online pH meter.

The pH meter will show real-time water pH on its displayer, and send command to chemical dosing pump after calculation by its inside logical program to select suitable chemical dosage. The chemical dosing pump will dose acid or alkali solution into water to automatically adjust water pH to range of 7.5-8.5.
