Possibility to reuse tapioca wastewater for algal cultivation

Abstract

Vietnam is ranked 16th in terms of cassava production on the world. In Vietnam, nowadays, it is predominantly used at raw material for tapioca production, both at household-scale (or small-scale) and large scale production levels. The processing for extraction of the cassava starch generates a great amount of residues, liquid and solid. The wastewater treatment technology now more used in many cassava starch industries is the system of stabilization ponds. However, some plants have deficiencies that result in the awkward odor release and low organic load removal. Correcting these deficiencies, my project has used the algae for treatment the excess the organic matter of Tapioca wastewater....
