Technical Feasibility
The core of this technology, the volcanic ash soil sintered body, possesses specific composition and physical properties, but its manufacturing process is based on general sintering techniques. This suggests low barriers to integration into existing ceramics manufacturing equipment or filter production lines. Furthermore, adsorbents are often incorporated into existing filter cartridges or packed beds, allowing for relatively easy integration into current systems without extensive equipment modifications.
Success Scenario
Implementing this technology could improve fine particle removal efficiency in factory wastewater treatment from 80% to 95%. This would facilitate easier compliance with discharge standards and is estimated to reduce annual treatment costs by approximately 20%. Additionally, a halved adsorbent replacement frequency could reduce annual maintenance labor by an estimated 15%. This could lead to both reduced environmental impact and optimized operational costs, alongside improved production efficiency.
