PUB and research partner to reduce energy consumption of seawater desalination. To meet Singapore’s water needs and reduce the energy costs of treating seawater, national water agency PUB and its research partner Evoqua Water have announced a new process that can potentially reduce the energy consumption of seawater desalination by half. Currently, up to 30 per cent of Singapore’s water needs is desalinated by reverse osmosis, a process which pushes seawater through membranes that filter out dissolved salts and minerals. (LINK).
