In the batch recirculation process, rinsewater (synthetic effluent) of concentration 312.39 mg/L was prepared using potassium chromate and used as an effluent in the process

As expected, the removal efficiency increased with increasing the adsorbent dose for a given initial metal concentration, because, for a fixed initial adsorbate

Citric acid, (NH4)2SO4, and NaCl have been found to be the most significant variables and their concentration levels have been further optimized by Genetic Algorithm based

In addition, the results indicate that EPS samples had more protein content when compared to cell lysis, although the amount of protein in the cell lysis increased greatly in

Figure 8: Ferric chloride dose – pH coagulation diagram for residual turbidity (NTU) at an equivalent settling velocity of 1.5 cm/min (concentration units on left hand scale show

With regard to the aforementioned results, it can be demonstrated that inclusion of high porosity open- cell metal foam into the structure of commercially available air

Other research (Liu et al. 2007) reported that biodiesel yield at 333K was higher than that at 343K, which is consistent with theory; because biodiesel transesterification is a mild

indicate that the hydrogenation rate is independent of agitation speed above 1200 rpm (the rate was not controlled by hydrogen mass transfer) at lower catalyst loadings (less
