Aqueduct for Ocean desalination
Posted by Mohamed Badr | , Egypt
Desalination processes produce large quantities of brine, possibly at above ambient temperature, and contain residues of pretreatment and cleaning chemicals, their reaction byproducts and heavy metals due to corrosion. Chemical pretreatment and cleaning are a necessity in most desalination plants, which typically includes prevention of bio fouling, scaling, foaming and corrosion in thermal plants, and of bio fouling, suspended solids and scale deposits in membrane plants.
Brine is denser than seawater and therefore sinks to the ocean bottom and can damage the ecosystem. Careful reintroduction can minimize this problem. Typical ocean conditions allow for rapid dilution, thereby minimizing harm.
