Globes, the pink paper (it is printed on pink paper, seriously), writes that
the Ministry of National Infrastructures plans to build a string of desalination facilities along the coast with a combined capacity of 750 million cubic meters a year. The facilities will discharge 3,000 tons of iron a year into the sea. Although seawater naturally includes iron, the Ministry of Environmental Protection is worried that the discharge of so much iron is liable to damage the marine environment, especially plants and fish.The membrane separation process produces ion free water and a stream of concentrated seawater, including iron cations. The process just sends back to the sea what it took from it minus some of the H2O. Now they want to avoid contaminating the sea with concentrated seawater. I think I know who is behind this idea and he is not intrinsically a bad person. His problem, I think, is that the water is red and highly visible, and it may call the attention of the blood-thirsty environmental movement, always on the look of a suitable victim. What better than an Environmental Ministry high official?
During the reverse osmosis desalination process, the facility removes iron from the seawater before it its pushed through the desalination membranes that produce fresh water. Ministry of Environmental Protection officials from the Coastal and Marine Division told "Globes" that they were unaware that the Ashkelon facility discharges this iron into the sea, in the form of "red water", and that they were taken by surprise when they learned about it.
The ministry officials claim that VID was also taken by surprise by the amount of iron discharge. The Ministry of Environmental Protection is worried that the construction of other desalination facilities using reverse osmosis technology will result in a huge discharge of iron and that there is no research on the effect on the marine environment.
The Ministry of Environmental Protection intends to ask the Ministry of Finance to ensure that future tenders for desalination facilities will require the operator to substantially reduce iron discharges.
The pic shows the Amazonas delta. The river flows through red laterite and carries lots of iron into the sea. Millions of tons. All tropical rivers are red.
