-------------------------------------------------------------------------------------------------------------
2. Describe the principle of the turbidity test and give one limit of it application (2pts)
Principle: -----------------------------------------------------------------------------------------------
Limit: ----------------------------------------------------------------------------------------------------------
3. Total suspended solids are mostly responsible for Turbidity. It is then possible to establish a correlation curve between TSS and Turbidity
3.1. Results in Table 1.1. showed the values of TSS and turbidity collected from the whole groups. Complete table 1.2. with the required information and establish the scatter plot of the original and log transformed TSS vs Turbidity.
3.2. Determine the TSS in mg/L for an unknown sample with turbidity = 75.2 NTU. Use the regression curve of Log10TSS vs Log10 Turbidity and show your calculation
3.3. If we have another sample of turbidity=360.5, can we apply confidently the same formula? Why?
-----------------------------------------------------------------------------------------------------------
4. In analytical field, we have different portable devises for measuring the physico-chemical properties of the wastewater. Why is it important to calibrate these instruments?
-----------------------------------------------------------------------------------------------------------
5. What is the mission of a bioprocess engineer in a wastewater treatment plant?
