Bangkok, Thailand | 8–12 December 2025 — ANGEL participated in the IWA Water and Development Congress & Exhibition (WDCE), showcasing solutions for medium and large-scale water treatment projects and bottleless RO water dispensers for public and office use.
Zhao Kai, Vice President of ANGEL Group, attended the opening and delivered remarks, highlighting ANGEL’s innovation and its commitment to international collaboration for sustainable development. The congress, co-hosted by IWA and the Asian Institute of Technology under the theme “Water, sanitation, and innovation – pathways to progress and a resilient future”, brought together around 2,000 participants from over 90 countries and regions.
Reshaping the Landscape of Intelligent Water-Quality Monitoring
On 9 December, Lei Jing, a technical expert from ANGEL’s Central Research Institute, presented ANGEL’s patented AIMS precision ion-sensing technology at a WDCE thematic forum, drawing strong interest from global water-sector experts.
As demand grows for accurate control of mineral-ion concentrations, AIMS addresses long-standing limits of conventional ion-detection devices. With an innovative electrode design, it reduces electrode loss, improves accuracy, and avoids frequent calibration. It upgrades monitoring from manual estimation and periodic sampling to real-time feedback and intelligent control, combining high-precision measurement with data visualisation. AIMS has won a Gold Medal at the Geneva International Exhibition of Inventions.
Optimised for cost and size, AIMS can be integrated into a wide range of water-treatment equipment and remain stable over long-term use without routine calibration. Beyond household water applications, it shows promise across research, biomedicine, environmental protection, and industrial and agricultural sectors—potentially lowering carbon footprints and supporting water recycling for more sustainable water management.
A New Paradigm for Efficient, Long-Lasting Water Disinfection
On 11 December at the IWA WDCE, Chen Qingyan, technical expert at ANGEL’s Central Research Institute, presented ANGEL’s new water-disinfection technology and its purification applications in the session on emerging contaminants and disinfection.
Addressing bacterial contamination in long-used purifiers, ANGEL spent seven years developing APCM “space-grade” antimicrobial technology, which physically attracts bacteria and ruptures cell membranes, achieving up to a 99.99% removal rate against ESKAPE pathogens.
Conference experts viewed it as a promising new approach to drinking-water safety, and ANGEL drew strong attention for its innovative, scenario-based solutions and its commitment to advancing efficient, intelligent, and environmentally sustainable water treatment.
