Raw water flows into the neutralization tank, and chemicals are injected and agitated according to the pH value of the raw water, then naturally discharged while the raw water is continuously neutralized.It is suitable for the treatment of wastewater that flows into the system continuously.
The standard pH range that can be handled in a single-stage treatment is pH 4 to 11.If the pH range is greater than this, a 2- or 3-stage treatment with multiple tanks is expected, with coarse neutralization in the first stage and fine adjustment in the second and subsequent stages.
*Neutralization reactions may require more chemicals than the calculated value due to factors that inhibit the reaction of chemicals.
We also offer neutralization titration test using sample water. Please feel free to contact us.
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.
Applications
General factory wastewater/ Hospital wastewater/ Laboratory wastewater/ Concrete plant wastewater/ Rainwater in factories /Cleaning wastewater/ Boiler wastewater/ Adjustment to a pH value suitable for treatment
