Sequencing batch integrated fixed-film activated sludge membrane process for treatment of tapioca processing wastewater

Tapioca processing industries are very popular in the rural community to produce a variety of foods as the end products. Due to their small scales and scattered locations, they require robust modular systems to operate at low capacity with minimum supervision. This study explores the application of...
