Continuous type (TPC type)

* Reliable design with a residence time of 15 minutes in the tank
* Optimal neutralization by time division proportional control
* Can be customized according to installation conditions


* Reliable design with a residence time of 15 minutes in the tank
* Tank material: In addition to SS400 + modified epoxy resin coating, SUS, FRP, PVC are also supported.
* Optimal neutralization by time division proportional control

The continuous pH neutralizer allows raw water to flow into the neutralization tank, and appropriately injects and stirs chemicals according to the pH value of the raw water to continuously neutralize the pH value, while the treated water is naturally discharged by overflow. To do. This device is suitable for drainage that constantly flows in. The 1st stage treatment has a pH of about 4.0 to 11.5 *, and if it is higher than that, it is a 2 to 3 stage treatment with multiple tanks, the first stage is roughly neutralized, and the second and subsequent stages are fine-tuned. I will.
In addition to standard specifications, we also accept customization according to your needs.

* Neutralization of pH value may require excessive injection due to factors that inhibit the reaction of chemicals, so the treatable pH value is a reference value. We also accept neutralization titration inspection with sample water. Please feel free to contact us.
