Process Evolution
2018
Walker Environmental strictly adheres to Industry 4.0 standards, globally launching and mass-producing GMBR. The membrane module has a lifespan of ≥30 years, with an MLSS as high as 10~30g/L. It requires no offline cleaning; simple online cleaning ensures long-term stable operation, requiring approximately 0 labor hours.
2008
Kyoto, Japan's membrane blank factory secretly loads GMBR (Gritgo Membrane Bio-Reactor) pilot test, ten years of ingenuity and five generations of selection, technology creates exquisite quality.
2000
Zenon of Canada leads the commercialization of conventional MBR on a large scale, increasing MLSS to 6~10g/L. However, the membrane module life is only 3~5 years, and offline cleaning is difficult (for example, for a treatment scale of 50000m/d, offline cleaning takes at least one month, and the labor cost for lifting/resetting/manual cleaning exceeds 2000 hours).
1980
Barnard in the United States launched a conventional AAO process for nitrogen and phosphorus removal, standard equipped with a secondary sedimentation tank, maintaining MLSS at 2~4g/L.
1914
Ardern and Lockett in the UK pioneered classic biological treatment aimed at BOD5 removal and complete nitrification, but were limited by secondary sedimentation tank solid-liquid separation, with MLSS only reaching 2-4 g/L.
