Desalination Plant is it viable for the P.I.

Medyo dreamer lang. As a child I wanted to build a dam later naging desalination plant. How complex or expensive is this project. Is there a giant barge that you can bring to regions that have water shortage? TIA

ganyan siguro gamit ng mga super rich countries sa middle east. they have the money, so possible yan...

dito malabo... kulang pera

A water desalination plant can be scaled to whatever size you want. But each "scale" will come with it's own pros and cons.

Large scale projects typically require massive amounts of investments and will need massive amounts of power to run. There are some techniques to lower power requirements though.

Small scale units would be the portable types. Enough to purify water for a family or two but would require frequent filter replacements since these would probably using reverse osmosis filters.

Medium scale would probably be the truck or barge transportable sizes. Depending on process type, they either require a lot of fuel/power or frequent filter replacements to operate continuously.

What type of project would you be referring to?

Personally regions having water shortage in the philippines is not really about water but about finding drinkable water supplies. A truck transportable water purification system would be the ideal solution.

A scale that can avert a looming water shortage.

Aside from water wastage control. How can we improve water supply.

Cloud seeding is not that effective.

Im curious, why cant we use sea water for palay planting and for irrigation?

Wala bang facility for this maski pang irrigation lang?

Meron akong napanood kailan lang sa TFC o GMA ba yun? tinitignan nila ang option na maglagay ng Desalination Plant (imported from Italy) it is made of solar panels tapos iinitin niya ang salt water tapos yung na-evaporate eh naiipon sa container as fresh water. Since its power is coming from the Sun, it is environmental friendly pa.

you are talking about reverse osmosis?matagal na atang ginagamit sa gulf yang process na yan e. dito they started to process the sea water to potable water last year.

pag dumami ang users, magmumura din yan.

Even a solar powered desalination system will produce certain of environmental pollution. The "waste" water exiting the system will be higher in salt concentrations and can harm the environment if it is not disposed of properly.

Anyway, you do not have to use Italian made systems to produce water. Using locally available materials, you can create a low cost solar powered desalination system.

A possible design is two "U" shaped tubs, one bigger than the other. The smaller tub filled with sea water. The bigger one is transparent and covers the smaller one. The lower edges has channels to pass water to a collection bottle or tank. The smaller tub should be colored black to maximize solar heating.

The above mentioned design is scalable from small to medium size simply by adding plumbing to flush out brine water and to refill with more sea water.

Hintayin natin ang mga inputs ng mga tsikoteers sa middle east at Oil rigs. I think oil rigs have their own desalination and waste water treatment plant. Israel also has good ideas on how to conserve water(drip irrigation)

Desalinization is really simple, given GH's model.

Heck, all we need is a gigantic sheet made of plastic garbage bags... say, about a kilometer long, say.

Hang it over the ocean on discarded coco lumber poles, in a tent shape, with collector bottles attached to the lower edges. Tada! You've just made the Philippine's biggest solar still. It produces desalinated water that is also free of all impurities.
