Evolution of GMBR Technology

　　In 1914, Ardern and Lockett in the UK pioneered classic biological treatment aimed at BOD5 removal and complete nitrification. Limited by secondary sedimentation tank solid-liquid separation, MLSS was only 2~4g/L.

　　In 1980, Barnard in the US introduced the mainstream AAO process for nitrogen and phosphorus removal, standard with a secondary sedimentation tank, maintaining MLSS at 2~4g/L.

　　In 2000, Zenon Company in Canada spearheaded the large-scale commercialization of MBR, increasing MLSS to 6~10g/L. However, the membrane module lifespan was only 3~5 years, and offline cleaning was difficult (for a treatment scale of 50000m3/d, offline cleaning took at least 1 month, and labor for lifting/resetting/manual cleaning was ≥2000 hours).

　　In 2008, the Kyoto Membrane Core Factory in Japan secretly launched a pilot test of GMBR (i.e., Greenclean Membrane BioReactor). Ten years of meticulous craftsmanship and five iterations of refinement resulted in high-quality technology.

　　In 2018, Greenclean (our company), adhering to Industry 4.0 standards, globally launched and mass-produced GMBR. The membrane module lifespan is ≥20 years, MLSS can reach 10~20g/L, offline cleaning is unnecessary, simple online cleaning ensures long-term stable operation, and labor is ≤10 hours.

　　The core of the GMBR process is the mature and reliable AAO process combined with advanced CPVC flat plate membrane components. Using membrane component mechanical retention to achieve complete separation of HRT and SRT, decoupling the contradiction between nitrogen removal and phosphorus removal, significantly improving the efficiency and stability of biological treatment. It perfectly replaces numerous structures and electrical equipment such as "secondary sedimentation tank + coagulation + sedimentation + filtration," simplifying the process flow. The regenerated effluent surpasses GB3838 surface water Class IV standards and can be directly reused for landscape or urban miscellaneous purposes.

Process Characteristics

　　1. The MLSS of the GMBR process is 5~10 times that of the traditional AAO process, enhancing shock load resistance, improving biochemical degradation efficiency, and reducing the biological toxicity of regenerated effluent.

　　2. The GMBR process independently controls HRT and SRT, directionally optimizing the nitrogen and phosphorus removal processes, and solving the problem of unstable TN and TP in regenerated effluent.

　　3. The GMBR process uses CPVC flat membranes designed with a Gaussian algorithm, with a concentrated pore size distribution (0.25μm). The regenerated effluent achieves "double zero" for fecal coliforms and SS, simultaneously solving the problems of high disinfection costs and difficult mud-water separation in winter.

　　4. The GMBR process features a unique design for in-situ online cleaning. The membrane components do not require "lifting in and out" for offline cleaning, ensuring "uninterrupted water" system operation and convenient maintenance.

　　5. The GMBR process has a short flow, small effective volume of the bioreactor, saving land occupied by secondary sedimentation and deep treatment, reducing land use by more than 50% compared to traditional processes.

Cost Advantages

　　1. The GMBR has a low total life cycle cost, less than 50% of competing MBRs.

　　2. The GMBR has the lowest water consumption of 0.2~0.3kW·h per ton, less than 50% of competing MBRs.
