Understand the filtration accuracy of the “3-Free” direct filtration technology in one article.
When traditional filtration technologies discuss “filtration accuracy,” they typically refer to the pore size of the filter medium—for example, 5 microns, 1 micron, or 0.1 micron. This represents a static, physical sieving precision: particles larger than the pore size are retained, while those smaller than the pore size pass through.

“Non-discriminatory influent acceptance” is one of the most revolutionary features of the 3-Free Direct Filtration technology, meaning that the system exhibits exceptionally strong adaptability to influent water quality: regardless of influent concentration, particle size, or fluctuations in water quality, it can operate stably without requiring sophisticated pretreatment at the front end.

How is the no-replacement-of-consumables feature achieved in 3-Free direct filtration technology?
The fundamental reason why conventional filtration technologies—such as sand filtration, bag filtration, and MBR membranes—require regular replacement of consumables is that pollutants irreversibly accumulate on or within the filter media, ultimately leading to clogging or damage that cannot be reversed through cleaning.

Innovative Treatment Process for Coal Slurry Water Recycling
The conventional “coagulation–sedimentation” process requires a large footprint, necessitates frequent sludge removal from sedimentation tanks, involves high chemical dosages, and struggles to consistently produce effluent of sufficient quality for reuse in high-standard applications.

“Power-free water production” is the most intuitive energy-saving feature of the 3-Free Direct Filtration technology. At its core, this means that the filtration process does not rely on any external power-driven equipment—such as booster pumps or vacuum pumps—and instead depends solely on the system’s inherent liquid-level difference as the driving force to enable natural water flow and filtration.

What is “3-Free” direct filtration technology?
During the water production (filtration) process, no external power equipment such as pumps is required to generate pressure. The process typically relies on the inherent potential energy of the wastewater—such as the water level difference or gravity—or on the osmotic pressure generated within the system as the driving force. Implementation: In ASSFBR, this is achieved through the use of a liquid-level difference.

ASSFBR (3-Free direct filtration) combined with AI replacing the secondary sedimentation tank represents a golden triad of low carbon, intelligence, and stability, offering significant advantages and broad prospects in AOA/AAO effluent standard upgrades, retrofitting of existing plants, and smart water treatment facilities.

ASSFBR perfectly meets the requirements of the AOA process.
The ASSFBR system is the optimal sludge–water separation solution for the AOA process, underpinned by a deep alignment of process compatibility, low-carbon synergy, and operational stability. It also perfectly addresses the core requirement of the AOA process for efficient sludge–water separation, as evidenced in five key aspects.

The All-Without-Components Direct Filtration (ASSFBR) technology, with its three core features—no power requirement, no consumables, and shock resistance—has emerged as a highly efficient water-treatment solution for coal-fired power plants, primarily deployed in four key application scenarios.

On December 2, the finals of the Third China International “Internet Plus” Ecological Environment Science and Technology Venture Capital Competition—sponsored by Beijing Enterprises Water Group (hereinafter referred to as the “Venture Capital Competition”)—concluded successfully in Nanjing, Jiangsu Province. The competition was co-hosted by the National Industry–Education Integration Community for the Ecological and Environmental Protection Sector and Beijing Enterprises Water Group, with joint sponsorship from the School of Environment at Tsinghua University, the School of Environment at Nanjing University, the School of Environment at Harbin Institute of Technology, the College of Environmental Science and Engineering at Tongji University, the School of Environment and Ecology at Chongqing University, and the School of Environmental and Municipal Engineering at Xi’an University of Architecture and Technology. It was organized by Nanjing University and the Beishui Education Center of Beijing Enterprises Water Group, with support from the Product Development Center of Beijing Enterprises Water Group and Beijing Touzhi Network Technology Co., Ltd. The event featured simultaneous online live streaming and cloud-based voting, attracting a total of 100,000 participants. Media outlets such as Xinhuanet, China News Service, China Environmental News, the Nanjing Radio and Television Convergence Media News Center, Yangtze Evening News, Modern Express, and Jiangsu Education Channel also provided coverage. More than 50 distinguished guests and judges attended the opening ceremony, including Shao Jin, a member of the Standing Committee of the Jiangsu Provincial People’s Congress and a member of the Education, Science, Culture, Health, and Sports Committee; Li Weiguang, Chair of the Teaching Guidance Subcommittee for the Major of Water Supply and Drainage Science and Engineering in Higher Education under the Ministry of Education; Lu Yanqing, Vice President of Nanjing University; Ren Hongqiang, an Academician of the Chinese Academy of Engineering and Dean of the School of Environment at Nanjing University; Yu Liguo, Rotating Executive President of Beijing Enterprises Water Group, Director of the Competition Organizing Committee, and Chairman of the National Industry–Education Integration Community for the Ecological and Environmental Protection Sector; Yu Liangfa, Vice President of Beijing Enterprises Water Group; Hang Shijun, Director of the Expert Committee of the Innovation and Entrepreneurship Competition and Chief Consulting Engineer of Beijing Enterprises Water Group; Wang Hongchen, Director of the Expert Committee of the Venture Capital Competition and Director of the Low-Carbon Water Environment Technology Research Center at Renmin University of China; Ma Defu, Deputy Director of the Competition Organizing Committee and Deputy Director of the Expert Committee, as well as an expert on innovation, entrepreneurship, and industry–education integration; and Mao Jianhua, Deputy Director of the Competition Organizing Committee and Deputy Director of the Expert Committee, who also serves as Vice President of Beijing Enterprises Water Group.
