"wah, so high~~~~"
It’s 1918 hour now. Haven’t tuck in any food except for a bowl of KokoKrunch half an hour ago. Finally most of the scheduled assignments have completed, not 100% but 7788. The whole week was packed with seriously major works. Tuesday we paid a visit to Indah Water and at 2 in the afternoon, we went to water treatment plant at Ayer Itam. Both places require a lot of energy and burnt away many, many fats!

INDAH WATER

We arrived at 9 a.m. The workers have not yet gone out to work (collecting sewage lar…) 2 ladies led us and explain step by step. They are engineers in the field I suppose. All of the treatment plants are high up, they are not underground but are like 2-floor high. Which mean that we need to go onto staircases to see what’s inside the big, big, big and deep, deep, deep poooool… From the outside, they really look clean, you know. Painted in white. Built out of concrete. We smelled a deep aroma of ammonia, saw a lot of dark brown coloured sewage. Those fluids which sent into the place will go through a tank which filled with woods for odor control. It’s impressive indeed. Unexpected. That’s why in certain process only the smell is severe and unbearable.
They have sediment tanks (there are 2) for solid to settle down and the leftover fluid-form one is effluent which then carried forward for further process. To our surprise, we saw something white and long; with tip in front-a condom.
“Why so long one?” I asked.
The funny-unsinkable-thing spinning on the surface with the other leaves. Initially I thought it’s toothpaste. But now when I re-think, how could toothpaste FLOAT?!
Effluent passes through the process of oxygenation. Providing oxygen for the beneficial microbes to decompose the substances within. Actually the HIGH tanks are all rounded in shape! I think from sky above would looks interesting. Well, the place actually near Penang International Airport. When I stood on top of the tank, I can saw the taxiway.
Ok, then there are 4 clarifier tanks (remember, tanks are high and big and deeeep). In this process, there are long “sapu” or brush to clarify the floating grease and material. As the technician said, the ‘thing’ spin and complete a cycle in 40 minutes.
The ‘brush’- you can imagine it as the long hand of the clock. The ‘long long brush is as long as its radius. It sweeps whatever ahead then when it finishes 1 round, the floating rubbish will be disposed of. How? I don’t know. Because we didn’t manage to wait for it to complete a cycle.
The suspensions are dried of as waste products and either disposed of to dumping area or taken away as fertilizers. After all process, the effluents actually look quite clear thou still coloured. The clear water will then channeled to discharge into the river. Yes, river, the people in-charge said. Well, so do you people still wanna “mandi sungai”? LOL~~~
