Rapid Startup of Aerobic Granular Sludge Using Cationic Polymer For Industrial Wastewater Treatment
The conventional activated sludge (CAS) process is used worldwide for municipal and industrial wastewater treatment. This technology has been used for over 100 years, providing sanitation and minimizing environmental damage. However, the approach is no longer deemed sustainable due to its extensive …
