We would like to introduce a case where we received a request from a hot spring bath facility for pipe cleaning work to ensure the sanitary management of their bathtub piping. Based on the usage situation and water quality test results, we determine the types and concentrations of chemicals to be used. We propose methods that we believe to be particularly effective. Furthermore, the water that accumulates after cleaning is not discharged as is; instead, it is neutralized to a level that can be safely drained to prevent any adverse effects on the environment. 【Case Overview】 ■Request Details: Pipe cleaning work for sanitary management of bathtub piping ■Key Points - Determine the types and concentrations of chemicals based on usage situation and water quality test results - Neutralize the accumulated water after cleaning to a level that can be safely drained before discharging *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where we delivered a pH neutralization treatment system for acidic well water. We received a consultation stating, "We are using well water, but we are troubled by water leaks in the water heater occurring after a few years." After conducting a water quality analysis, it was found that the pH value was low. It was believed that this was causing the copper pipes in the water heater to corrode and lead to water leaks. Therefore, we proposed a pH neutralization treatment system for the well water, which led to the installation of the system. Since there was an existing water storage tank, we adopted a circulating neutralization method. 【Case Overview】 ■ Installed Equipment: pH neutralization treatment system for acidic well water ■ Consultation Content: Using well water, troubled by water leaks in the water heater occurring after a few years ■ Key Points - No chemical agents used, only natural materials - Measures taken to prevent excessive dissolution from becoming too alkaline *For more details, please refer to the PDF document or feel free to contact us.
