A biological reactor is getting wastewater containing 1 mole/L acetate ions as carbon source. The following reaction takes place in the bio-reactor: Assume that all acetate ions are consumed and ammonia serves as a nutrient source. Given that 1 g acetate exerts 1.07 g COD; 1 mole bacteria = 113 g VSS; 1 mole acetate ion = 59 g. Value of observed yield is ________________________ (in g VSS/g COD, rounded off to two decimal places).
