Development of biological oxygen demand biosensor for monitoring the fermentation industry effluent. [PDF]
ISRN Biotechnol, 2013 A biosensor was developed for the determination of BOD value of fermentation industry effluent. The developed biosensor was fabricated by immobilizing the microbial consortium on cellulose acetate (CA) membrane in close proximity to a DO probe electrode. The microbial consortium was harvested from the fermentation industry effluent.

Modelling biological oxygen demand in wastewater of Arak City, Iran
Journal of Water Sanitation and Hygiene for Development, 2015 Due to the fact that the laboratory analysis of biological oxygen demand (BOD) is time-consuming and uncertain because of some interferences during analysis, automatic estimation of BOD by modeling methods would be of great importance to researchers. The main aim of this study was to compare the performance of three models for the prediction of BOD in ...
