How a desalination plant works

Water is a primary asset, indeed the very first ever. However, sometimes it seems that the supply that Mother Nature offers to quench the thirst of all the inhabitants of the world can begin to end. So what did man invent to make up for this future problem? The desalination plant.

Just think of those produced by https://www.bpwatertech.com/en/  a leading Italian company in the sector, which has made sustainability a strength, from the moments that not only does it drain the water but it does it using the energy of photovoltaic systems

Drinking sea water

 Drinking water could become a reference point if derived from those seemingly unsafe water sources.

And so thanks to huge large-scale facilities, man is planning to get more and more drinking water from the sea. Today it is possible to build efficient desalination plants that can also contain energy consumption.

Taking advantage of modern technologies to their advantage, man derives drinking water from the sea, at an inexpensive cost. In this way, in the future, water can be guaranteed for everyone, even in the poorest regions of the planet.

Reverse osmosis

Many believe that reverse osmosis is a very expensive process. This can apply to the plants of the past. But for those of the latest generation, the road is getting easier and easier. The costs of large reverse osmosis desalination plants have been offset by the use of recycled energy such as that obtained from photovoltaic systems. The main problem with reverse osmosis systems has always been that of blocking the membranes. Thanks to different filtering systems, used before the sea water reaches the membranes, it is possible to avoid clogging. Furthermore, this new system does not require polluting chemicals to clean the filters.

 How a modern reverse osmosis desalination plant works

The water that comes from the sea passes first through a filtering basin in which there are three different layers of natural materials: lava stones, sand, gravel. After this natural filtering the water reaches the cylinders containing the membranes, in these large plants, we can get to have over fifty thousand of these cylinders. Inside the cylinders, a series of membranes with infinitesimal thicknesses, retains the salt. Water is introduced into the cylinders with a pressure of seventy atmospheres.
