How to Buy a Desalination Plant?

This is an overview of major steps needed to create a Request For Quotation for a reverse osmosis desalination plant.

I was asked this question recently and a person expected practical succinct guidelines from me on the spot. As a recourse I sent him a link to my post "How to prepare SWRO desalination plant bid" with a promise to return back. 

Googling this question does not give any results, neither visiting the sites of major engineering services providers and consultants. Obviously, it is an experience nobody is willing to share. Even worse, lately the last two contractors removed from their websites the client's questionnaires.

Unlike internet transactions you make selecting nice pictures of things you trust you get, buying desalination plant is pivoted around the request for quotation having the power of contract. Its core is a set of technical and commercial requirements and conditions (R&C) covering design, manufacturing, and operation of the plant. To meet R&C, customization is needed - some parts are added or removed from the standardized plant scope. 

To get what you really need, R&C shall be defined and thoroughly checked before any contact with the contractors to avoid biases in R&C (for instance, excluding other contractors from bidding). So nip in the bud your desire to press "Contact Us" button and follow the wisdom of 57 percent of the buyers who make purchase decisions before ever talking to supplier. Before this nearly all buyers (97%) make online research. 

In compiling R&C I suggest two universal principles to follow. The first relates to your strategy in R&C execution verification.

        Reverse Osmosis is meaningless, excessive energy consuming process, using expensive high pressure pumps, expensive membranes, and referring to micro pre-filters. Reverse Osmosis is a process which is enforcing that most of worldwide sea shores are left deserted due to expensive equipment and expensive operation cost.

       Reverse osmosis is always coming with false claims of very low energy consumption, which correspond to new membranes, while the truth these false claims of low energy consumption fade away after few days of using the expensive membranes, due to their fouling. The theoretical osmotic pressure for seawater is about 35 atm, while the actual osmotic pressure is 70 atm for new membranes, while after a month of operation the osmotic pressure is beyond 90 atm !!!???

       When those who are promoting reverse osmosis discovered they are consuming a lot of energy, they are coming with energy recovery system to use high pressure discarded water to pass through water turbines. This way doubling the expenses of water production.

       We are referring to room temperature evaporation, a process which does not consumes any energy, the energy needed to separate pure water is simply obtained from the bulk of seawater body cooling it No external supply of energy. This is the process used by the CREATOR worldwide to generate pure rain water out of seawater, and we are using the same concept in industrial water coolers.

      Our equipment is very simple (please visit our website naturalseawaterdesalination.com), as the process occurs at room temperature then the material used is mostly plastics, and our equipment are less than half the price of reverse osmosis.
