Continuous Flow Neutralization: Raw water flows continuously into the tank, where chemicals are injected and agitated based on pH, then naturally discharged.Proportional Control: Features time-division proportional dosing for optimal pH adjustment.
Residence Time: Designed with a 15-minute retention time for reliable, complete reaction.
Tank Materials: Standard SS400 with modified epoxy coating; optional SUS, FRP, or PVC.
pH Range (Single-Stage): Handles raw water between pH 4 and 11.
Multi-Stage Systems: Raw water exceeding pH 4–11 requires 2- or 3-stage treatment (coarse neutralization in stage 1, fine adjustment in subsequent stages).
Testing Services: Neutralization titration tests on sample water are available (actual chemical consumption may exceed theoretical values due to reaction inhibitors).What is Time-Proportional Control

This is a control method to suppress hunting (excessive back-and-forth between the target value) caused by excessive chemical injection in pH neutralization.
The amount of chemical required for pH neutralization decreases as the target pH value is approached, but if the metering pump is operated at a constant rate, the target pH value will be greatly reduced due to over-injection of the chemical (e.g., ON-OFF only control). To prevent this, continuous operation is performed when the pH value is far from the target pH value, intermittent operation can be used to gradually bring the pH value closer to the target value. This control method is called time-proportional control. By varying the pump operation time proportionally to the target pH value, this prevents excessive injection of chemicals and ensures smooth adjustment to the target pH value.
