Good News: Exclusive Honor! SOTEC Named "Industry Leader in Non-Evaporation Treatment of Landfill Leachate"

As the largest and most influential water treatment event in the Asia-Pacific region, the Qingdao International Water Conference is a top-tier global water industry platform jointly initiated by the China Association for Science and Technology, Qingdao Municipal People’s Government, together with authoritative international organizations including the World Water Council (WWC) and the International Water Association (IWA), and has been held for 20 sessions to date. Centered on the theme Water – Source of Life, Foundation of Development, this year’s conference ran through July 4, featuring nearly 50 special sub-forums and over 460 professional reports across eight core thematic modules. Distinguished attendees included Wang Bo, Member of the Standing Committee of Qingdao Municipal Party Committee and Vice Mayor of Qingdao; Wang Xiaokang, President of China Industrial Energy Conservation and Clean Production Association; Eric Tardieu, Secretary-General of International Network of Basin Organizations and Vice Chairman of the World Water Council, as well as thousands of industry experts, scholars and entrepreneurs from home and abroad. Widely recognized as a barometer for technological advancement in water resource utilization, this award underwent multiple rounds of expert evaluation organized by Adi Desalination Center, which guarantees the professionalism and international recognition of the selection results.

SOTEC has previously been honored with awards such as the China Water Industry Star Award – Outstanding Product Award and China Outstanding Water Treatment Craftsman. This latest accolade further validates its robust strength in spearheading industrial progress on a sustained basis.

SOTEC’s qualification for this award is anchored in its self-developed TLDR (Total Leachate Degrade Recycle) full-quantity treatment technology for concentrated leachate via non-evaporation approaches.

This integrated process consists of pretreatment + DT high-pressure material membrane separation + ammonia recovery + heterogeneous synergistic catalytic oxidation + ultra-low-temperature drying. The treated effluent can stably satisfy the requirements specified in Table 2 or Table 3 of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008), with the solid residue rate controlled below 5%.

Compared with conventional evaporation technologies, this solution features lower operational costs, smaller footprint, shorter construction period and highly flexible modular equipment configuration, representing a pioneering leading technology domestically. It has been successfully deployed in engineering projects in Renshou, Zigong, Jianyang, Chongqing and other regions with remarkable demonstration effects.
