InGlobal Water Intelligence2 developed a desalination cost estimation program available on their website for reference by professionals interested in capital, operations and maintenance costs associated with desalination plants. Desalination is a process that extracts mineral components from saline mi-centre.com generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture.
Saltwater is desalinated to produce water suitable for human consumption or mi-centre.com by-product of desalination is salt. Desalination is far more expensive than using water from land supply sources.
The cost is very high and so it cannot be afforded by everyone who needs it, but because the desalinisation technology is improving fast, so the costs are beginning to fall, making it more affordable to.
