The "Carbon Dioxide Neutralization Device" efficiently and economically treats alkaline wastewater using a special gas-liquid contact device. Since carbon dioxide is used as a neutralizing agent, it is safe to handle. Even if there is an operational error leading to excessive addition, the pH of the treated water remains within the neutral range of 5.8 to 8.6, posing no problems. 【Features】 ■ Extremely high reaction efficiency of carbon dioxide ■ Low consumption of carbon dioxide ■ Short neutralization time, resulting in a compact device ■ Requires a small installation area ■ High tolerance to fluctuations in treated water volume *For more details, please refer to the PDF materials or feel free to contact us.

Our company has been engaged in the research and development of turbidity water treatment systems associated with construction work since early on, and we have successfully commercialized economical and high-performance treatment facilities. The treatment of turbidity water discharged from construction projects such as dams, tunnels, and aggregate plants is a crucial issue that must be resolved first in order to advance construction work. We conduct the selection of coagulants suitable for the properties of turbidity water, water quality testing, and on-site surveys to carry out design and manufacturing that is well-suited to local conditions. 【Features】 ■ Sedimentation tank: Thickener uses an automatic lifting rake ■ Filter press: Large model used, easy to operate ■ Neutralization: Carbon dioxide method adopted ■ Coagulant selection: Based on water quality tests, brand and dosage are selected ■ Automation: Automatic control system adopted for all operational aspects *For more details, please refer to the PDF materials or feel free to contact us.
