Two weeks back my father told me that they are planning for a family trip to Ennore port and whether I would be interested to visit the same. Who would say a NO?? Immediately I nodded Yes and yesterday morning we were all set for the trip.
We were supposed to assemble at my dad's office at 7AM. His office is not new to me as I always have the habit of visiting his office for some reason or the other. Since its a govt office you don't have strict rules about visitors. And my father being one of the senior officer I was always treated with a red carpet welcome ;) A visit to my mom's office would be completely different. We can go there only during Ayudha pooja celebration. But that would be a more friendly environment since everyone is of equal role and friends for almost 3 decades now. I enjoy being in both environments :)

Nice colour combination ;)
We (dad, mom & myself) reached dad's office at around 6.50 AM . As people arrived one by one there were introduction between families and it was good to see people of various ages. Starting from a 1 yr old kid to 50 + years oldies :P. Breakfast arrived at 7.30AM from Hotel Ananda. After completing our breakfast, we were asked to come down and board the bus. There were totally 3 buses. And each bus had an in-charger. My dad was in-charge for the third bus and hence we had no other choice. Had to go only for the third one :)
Entrance of CWDLThe first destination we reached was CWDL (Chennai Water Desalination Ltd) at Kattupalli. As the name says, they desalinate the sea water and convert it into drinking water. Looks like they are still in testing phase and guaranteed that by Jan 2010 this plant will be completely on the GO. They said that the production cost per litre is around 48.6 paise and the target is to produce 100 Million litres per day. We were taken through each phase of the process.
Taken from the terrace of Tank 1 (Water mixed with Chemical). The buildings on both the sides of the road are the Gravity settler station and the next set is the Gravity sand filter station. The final block is the pumping stationAs explained to us, Initially they take sea water and fill it into a tank. While doing so, the chemical Ferric chloride is added to sea water. When the person said Ferric chloride my mind was thinking Whether it is FeCl
3 or Fe
3Cl :)). After this the water is agitated (they said its a natural agitation as the path of the water flowing is set like a snake) and then it passes through two stages - Gravity settler and Gravity sand filter. After this the water is pumped to the final station where the incoming is just salt water (all other particles in the water have been completely removed in the initial phases including the chemical added earlier). At this place they use the concept of reverse osmosis to separate salt from water. They said there are 7 filters which is involved in this reverse osmosis process and finally the outcome is pure desalinated water. We also tasted the water and it was actually as good as the outcome of any water purifier (only taste and clarity :P Other technical details me the no idea :)) ).
Final section where water is completely desalinated For people like me who do not know what is an osmosis process, they explained that water (lighter density) when we drink gets mixed with blood (higher density) in our body. This is called osmosis process. Hence in reverse osmosis process they apply pressure to the salt water and after passing through the 7 filters with this pressure the salt is completely removed from water. It was actually more like an educational trip than a casual trip. But still it was nice to know these things. Then we started to our next location - Ennore Major Port.
Other two buses waiting in front of us for security check clearance at the entrance of Ennore major port :) To be continued..
