As for the purpose of repair/renovation work, 73.3% cited "corrosion prevention", and about half of them cited "cost was higher than expected" as an issue after performing repair/renovation work. Specifically, there are episodes such as ``I was afraid of the impact on the building because it was a large-scale construction''. In addition, as issues during digestion tank repair/renovation, "Cost-effectiveness calculation (appropriate repair cost calculation)" (83.3%) and "High processing cost" (66.7%) were cited, and "Parts There were also concerns about whether the delivery date would be as planned due to shortages, etc. Next, when asked about issues and hurdles at the stage of examining digestion tank repair/refurbishment, "calculation of cost-effectiveness (calculation of appropriate repair costs)" and "high processing cost" were the highest at 78.3% each. have become. It can be read that there are issues related to "cost" in all processes, such as the examination stage, execution stage, and completion stage. Approximately 70% of respondents hoped for further efficiency improvements in the dehydration and water treatment of digestion tanks in the future, and approximately 60% believed that an "overall treatment design tailored to the site" would be necessary to achieve this. I understand. Finally, 65.3% expressed interest in the treatment method of "temporary water treatment," which can effectively treat muddy water in a short time. In general, digestion tank repair and renovation work requires a large amount of money, but with the "temporary water treatment" treatment method, it is possible to handle only the necessary repairs at the optimum cost. In addition to being time-saving and cost-saving, it is also an environmentally friendly solution, so it is likely to attract more and more attention in the future.
