Summary

In the article, the author talks about the advanced instrumentation technology that they will use with the wastewater treatment works (WWTW) in the City of Cape Town. The city contracted with the SSI Company to develop its WWT in northern suburbs of Cape Town. Also, he mentioned that the system will make a big jump for the city. Therefore, the company will use some techniques to improve their project. They will use many systems to filter and clean the water from infection. Moreover, they will make the software for these systems and test it to be sure it is in good condition. Therefore, the company chose the latest version of technology that is available in the market. In the end, the author says that the whole project will finish in August, 2010.

Reaction

I enjoyed with this article because my major was instrumentation technology and I will continue with the electronic systems. These two majors are related to each other. This article talked about the advanced instrumentation technology which is used in WWTW, and which is the same thing that I dealt with before, but in SAMREF refinery. The author mentioned in his article some of the systems such as programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) that they will use them to control their project. That is a good step for the future, because I worked with these systems and I knew that these systems are the best for controlling any process. They show you all the processes of the units and how they work. Also, they find the problems that happen during the processes and you can fix them very easily. They show you who made the mistakes in the process. For example, when the operation department made a mistake during the processes, they may say we didn’t make any mistake and the department that made the mistake is the maintenance department, so the company got confused and couldn’t find who made the mistake. This usually happened in the old systems, but with the PLCs the company can find who made the mistake. In terms of instruments, the company used a lot of advanced instruments in their project, which are making the operation of the wastewater treatment more flexible. Therefore, I agree with what they did for this case. Finally, the most important thing of this article is the wastewater treatment, which is the biggest problem that faces many countries. The people use a lot of water when they take a shower, wash their car, etc, and after all of these, the water becomes wastewater, and they don’t know the importance of the water. They don’t have any idea about how much it costs when the government desalinates the sea water. Therefore, we have to decrease the uses of water to preserve it. These sentences are my reaction and all of them are based on my knowledge and experience.
