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.

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.
