| ABSTRACT |
|
A wastewater treatment plant recently had failures in bioassay tests. There are several industries discharging wastewater to the sewer. There was a strong relationship between total inorganic carbon and % inhibition after biological treatment. The toxicity of the textile mill wastewater was significantly reduced by adding bicarbonate. The sodium bicarbonate addition gave a significant increase in microbial activity indicated by the increase in the oxygen uptake of sodium bicarbonate added systems. This strong effect of bicarbonate addition on oxygen uptake might be due to the binding effect of sodium bicarbonate with ion state metal compounds giving strong toxic effects for microorganisms. In addition, when the percentage of the textile mill wastewater exceeds 5%, a high toxicity remained after TF biomass treatment. |
