Koh Chang proposes Reverse Osmosis to control water shortage

Deputy Chief of Koh Chang (เกาะช้าง) Sub-district has proposed to use Reverse Osmosis (RO), a system used to distil sea water to fresh water, to control water shortage.

Mr. Sakprasert Chareonprasit (ศักดิ์ประเสริฐ เจริญประสิทธิ), Deputy Chief of Koh Chang Sub-district, revealed that Chang Island will face water shortage from January-May every year. Five-star hotels and resorts will not encounter water shortages as they have their own underground water pumps. However, small hotels and resorts have to buy fresh water.

As for the long-term plan to prevent water shortage, reservoirs will be constructed on the island and RO system is expected to be installed.

What's wrong with using the sun to distill seawater? so much sun and sooo much seawater. I guess that's a big nono for the powercompanies...

just an idea.

About time too!! I can't believe these are not commonplace already.

From what I've read, desalination plants of any significant capacity are VERY expensive to construct. These are the traditional reverse osmosis types and not the solar ones.

There is a big desalination plant being built just south of Perth. There is great concern locally about the return of super saline water back to the bay it is in, and that the state government are keeping secret the cost of the large amounts of power the plant is going to use.

Will Ko Chang be able to supply the power and the surrounding waterways be able to disperse the effluent from the plant?

It would appear that some people are asking relevant questions.

To answer these questions, planning is required.

What country are we talking about here?
