The problem of the halogens and free radicals in the desalination process.

Start by obtaining a copy of information from Niro Atomizer== a Danish Firm which has been making flash distillation with Vapor Recompression systems for many years.

Working with traditional methods for hardness removal will require large settling ponds, a sophisticated mixer system, significant production space, and high equipment, energy, and operating costs.
Besides, it is also necessary to neutralize large amounts of iron and other metals, including heavy ones.
These circumstances require huge capital and operating costs and do not promise successful cleaning.
We have an unconventional water purification system using vortex layer devices (AVS). This system cannot guarantee the complete elimination of mineralization, but it can reduce it due to the almost complete conversion of calcium and magnesium compounds into the sediment.
In this way, the hardness can be brought to a level that meets the standards of maximum permissible concentrations.
At the same time, it is possible to reduce the content of iron and other metals, including heavy ones, also to the level of permissible concentrations.
It is not possible to eliminate mineralization because it is mainly sulfates and chlorides of alkali metals, which do not form compounds that are slightly soluble or insoluble in water.
They can only be removed by distillation, ion-exchange chromatography, or various types of electrolysis.
However, the proposed method makes it possible to reduce many times the costs of reducing hardness, removing heavy metals, significantly accelerating the separation of liquid and solid phases, reducing the cost of buildings and working areas, and reducing the consumption of reagents.
If water as impurities contains mainly carbonate and non-carbonate hardness, then they can be brought to a composition that meets the requirements

Hi Nada:
In the world of Process Engineering, valves play a large part and with many decisions to be made regarding the correct method of controlling pressures and flows. Being based in South Africa and with some knowledge of requirements on the Africa Continent ...... simplicity should be the keyword as well as minimum Maintenance requirements. We apply this principle in our range of Control valves where simplicity and tamperproof reigns supreme. These valves are easy to manufacture in Stainless Steel or Super Duplex in order to be resistant to water with high Chlorides. Please have a look at our catalogues ..... if there are any questions I would be happy to assist.
All the best with your thesis.
