Aerobic treatment of maize-processing wastewater (nejayote) in a single-stream multi-stage bioreactor

Aerobic treatment of maize-processing wastewater (nejayote) in a single-stream multi-stage bioreactor

Journal of Environmental Engineering and Science 2(5): 401-406

The manufacturing processes of tortillas, corn chips, tortilla chips, and related products yield a liquid waste called nejayote. Nejayote waste from a maize-processing plant (La Blanquita Company, Mexico). This waste causes serious pollution problems since its chemical oxygen demand (COD) is very high, from 25 000 to 30 000 ppm. To reduce the pollution potential of this effluent, the use of a cascade of three continuous flow bioreactors-in-series is proposed.
