【Case Study】Neutralization Treatment at a Concrete Plant

Collected the supernatant from the sedimentation tank and neutralized it! An example of our support in preparing documents for submission to the government office.

We received a request from a concrete factory in the Chubu region stating, "We would like to neutralize the wastewater generated from washing concrete trucks." Upon further inquiry, we learned that while there is an existing sedimentation tank, there is no neutralization equipment. They were urgently considering this matter due to a notice from the authorities. Therefore, we proposed a flow where the supernatant from the existing sedimentation tank would be neutralized and then discharged. Since the sedimentation tank has a strong alkaline condition, we suggested using a corrosion-resistant submersible pump of the LC type and installed electrodes for liquid level control to ensure only the supernatant is drawn. This matter involved multiple documents due to the authorities' notice, but our company supported the submission of these documents, allowing us to clear the issues without any problems. [Case Overview] ■ Client: Chubu Ready-Mixed Concrete Factory ■ Supplied Product: Automatic pH Neutralization Device ■ Application: pH neutralization treatment of concrete wastewater (including rainwater) *For more details, please refer to the PDF materials or feel free to contact us.
