Desalination/Reuse
Desalination applications
As global water scarcity becomes an increasingly pressing issue, innovative solutions like desalination and water reuse are essential for ensuring a sustainable water supply. Desalination involves the removal of salts and minerals from seawater or brackish water, providing quality water that can be reintroduced into the drinking water cycle.
Water reuse, on the other hand, involves treating wastewater to a high standard so it can be safely reused for various purposes, including agricultural irrigation, industrial processes, and even potable water supplies.
At Lhoist, we offer advanced technologies and products for both desalination and water reuse. Our solutions are designed to maximize efficiency, reduce environmental impact, and ensure the highest quality of treated water.
Remineralization / pH adjustement
For drinking water production, it is indispensable to replenish the permeate from reverse osmosis membranes or distillate from thermal processes with vital minerals. For this purpose, remineralization using Akdolit® lime-based and filtration products presents many advantages.
In addition, product water from desalination processes can cause corrosion in metal piping or concrete tanks. Consequently, desalinated water requires stabilization to ensure the protection of the distribution network and of human health. Akdolit® lime-based and filtration reagents are effective for pH control and offer greater flexibility over alternative alkali in terms of water input quality.
Pre-filtration
A prefiltration step is highly recommended to remove algae, turbidity and suspended solids, in order to protect the RO membranes and extend their lifespan. Akdolit® offers high-performance filtration materials with large contact surfaces and high retention capacity, which have proven their reliability and effectiveness in numerous applications.
