Techniques for making drinking water from salt water are not new. Why then is it that there are still more than 2.2 billion people in the world who experience some form of water scarcity? That is the question Brineys has asked himself. We concluded that many projects and initiatives aimed at reducing water scarcity depend on donations to charities. In addition, many projects are not monitored, so it is unclear whether projects have been successful.
According to Brineys this can be done differently. In addition to producing drinking water, we also want to do something with the residual product: salt. This salt is packaged in Kenya and sold in the Netherlands as sea salt with a unique story. By using Brineys Salt in the Netherlands you contribute to solving water scarcity. The proceeds of the Brineys Salt are used to maintain the drinking water production factory and to provide water to people with water shortages.
How does Brineys make drinking water from seawater?
It is not healthy to drink sea water because it contains sand, bacteria, viruses and salt. Drinking water can be produced by removing these parts. In that case, seawater is the input and this is separated into drinking water, brine water (extremely salt water) and contaminants.
Salt is the most difficult of all contaminants to separate from the water. This is done by pumping the water through a reverse osmosis membrane at high pressure. This membrane is actually a very precise filter. The filter holes in the reverse osmosis membranes are very small. 1 micron is equal to 0.001 millimeters. A reverse osmosis membrane filters all pollution from the water that is larger than 0.0001 microns.
Most seawater passes through this membrane and becomes drinking water. That is how Brineys will produce drinking water. What remains is the extremely salty brine water.
How does Brineys make salt from brine water?
The brine water that remains has already been separated from other contaminants such as organic matter and sand. The only thing left from the brine water to produce salt is the remaining water that has not passed through the membrane. For this we need two things: the sun and the time. A salt pan is filled with brine water and the heat of the sun evaporates the remaining water. Over time, the salt will crystallize as soon as the water evaporates. That's how Brineys will produce salt.
