Technology Principle
The key technology principle of this product is the membrane bioreactor constituted by the organic combination of biotechnology and MBR membrane technology. It makes the hydraulic retention time (HRT) and sludge age (SRT) completely separated. With high efficiency solid-liquid separation performance, high activated sludge retention, and activated sludge of 5000-11000mg/L ultra-high concentration can be formed in the reaction tank, thus completely degrading the pollutants in the sewage and achieving water purification.
