Clues
- Bacteria divide by a process called _______ _______. (6,7) (6, 7)
- Chemical Oxygen Demand (COD) test produces toxic waste products so is less sustainable than BOD test. The advantage of COD is that it measures pollutants that are ___-_____________. (16)
- For circular settlement tanks, the influent needs to be introduced without resuspending the settling sewage. So a component is added to the tank which reduces the turbulence of the influent. What is that component called? Hint: It is 1-4% of the area. (8, 7)
- Formula for calculating the velocity of settlement. Importantly, it relies on 3 assumptions: discrete particles, spherical shape particles, and laminar flow. (6, 3)
- Problematic process that occurs if the tanks are too large, too deep, and Hydraulic Retention Time (HRT) is too great. This issue brings odour problems and rising sludge. (9)
- SOR is the main parameter in designing primary settlement tanks. What does SOR stand for? Clue: lecture slides '6 Primary Treatment'. (7, 8, 4)
- The first process in preliminary treatment of wastewater. It involves removing solid debris and grit. (9)
- The growth rate of a Micro-Organism can be measured by this empirical equation. (5,8) (5, 8)
- The main process in primary treatment of wastewater. The purpose is to remove fine solids. (10)
- The unwanted process of groundwater seeping into sewers, thus diluting the sewage and increasing the volume going to treatment plant. (12)
