Technology Used in Sea Water Desalination Vessels
In this technology we make use of the old tankers and crude oil carriers that have undergone a conditional assessment survey stating that the vessel cannot be further used to carry oil or oily products due to its reduced hull thickness. These vessels are purchased and modified into seawater desalination vessels.
The modification is done in dry dock where the cargo tanks are converted into the fresh water storage tanks, and we install the new sets of reverse osmosis plants for desalination of the sea water. To make it drinkable, we used the water treatment plants like chlorine sterilization conditioning, the Electro-Katadyn method of sterilization, and the use of UV filters to remove bacteria and other microorganisms from the fresh water. The treated water is then stored in the storage tanks and kept ready for discharge at appropriate water platforms.
On the shore, we built water platform-like structures where the ship is able to reach the platform and deliver the fresh water to the shore through a flexible cable connecting the ship’s discharge to the shore side tanks.
Normally the platforms are built near to the shore at the distance of (1-2 km) as the ship can directly come to the platform and pump out the fresh water to the shore tanks.
These platforms are built at equal intervals on every city near to shore, as it can supply freshwater to those cities at a regular intervals of time, say about twice a week.
