(Chinese) Group no.: 1 Class: AS114103/A1 Date: 24/5/2013 Assignment 1 –Tutorial Questions on Chemical Oxygen Demand (COD) Experiment 1. What is the function of using KHP in the COD test? (2 marks) KHP is used as a control standard because KHP is stable pure organic compounds which have the theoretical value of COD(500ppm)‚ so it can used to gain an idea of how accurate the lab was. 2. Calculate the theoretical oxygen demands(g oxygen/g compound) for glucose

respectively‚ after the first hour of aeration. This indicates that COD was degraded the fastest in the first hour of aeration after the anoxic phase. The high removal of COD was due to the fact that COD concentration decreased during the first two hours of the anoxic phase because the heterotrophic bacteria used COD as a source of organics for denitrification. In the next 2 hours of aeration‚ ammonium was oxidized faster than COD and reached 89%. This was a result of the increase in DO concentration

About the African Penguin The African Penguin‚ Spheniscus demersus‚ is also called the Blackfoot penguin and the Jackass penguin. This penguin is found off the coast of Southern Africa. Penguins are birds that cannot fly‚ but penguins swim very well and spend most of their lives in the sea. African penguins can swim at a speed of about 4.3 to 15 miles per hour (7-24 kph). This bird got its name from the donkey- or jackass-like sounds that it makes. Anatomy: African Penguins are about 2 feet (60

for segmenting the international tourist market to Cape Town‚ South Africa. A backpropagation neural network is used to complement the segmentation by generating additional knowledge based on input–output relationship and sensitivity analyses. The findings of the self-organizing neural network indicate three clusters‚ which are visually confirmed by developing a comparative model based on the test data set. The research also demonstrated that Cape Metropolitan Tourism could deploy the neural network
