We received a request from a stainless steel processing factory regarding their newly installed acid washing equipment, expressing the need to neutralize the wastewater. The installation space was very limited, and the neutralization process involved strong acid (pH 2-3), but we designed a two-stage treatment (neutralization tank to discharge tank) to save space. In the case of acid washing wastewater, especially since it was indoors, we were concerned about the strong acid atmosphere, so all the frames were made of stainless steel. We also adopted the HTX model from H2 for the chemical injection pump used to inject caustic soda.

We received an inquiry from a concrete manufacturing company stating, "We would like to neutralize rainwater on our premises to eliminate the possibility of rainwater draining away being alkaline, as it absorbs concrete dust." Since the neutralization of rainwater, which falls irregularly, raises questions about how to collect it and what size of neutralization equipment is needed, there were challenges regarding the size of the collection pit and flow. We proposed a recording device (receipt type), pH monitoring in the discharge tank, and a flow design to prevent the discharge of rainwater that exceeds the standard values using a return pump. 【Case Details】 ■ Client: K Corporation, Concrete Manufacturing and Secondary Product Manufacturing ■ Purpose: Neutralization treatment of rainwater on the premises *For more details, please download the PDF or feel free to contact us.

We received a request from a university's Faculty of Science and Technology to treat wastewater from concrete used in their research. The treatment volume was small at 500L/Hr, and the pH was around 11, but space was limited, and the budget was constrained. As part of the project, we implemented measures to prevent high-alkaline water from flowing into the existing sump, and we handled the secondary piping and electrical work in-house to keep costs down. If you are looking for a neutralization system manufacturer that can incorporate the user's wishes into the design and manage the entire construction process, please feel free to contact us. 【Case Details】 ■ Delivery: A certain university in the Tokai region ■ Application: pH neutralization treatment of laboratory wastewater *For more details, please download the PDF or feel free to contact us.
