Water Treatment and Desalination Systems

Plants and devices that make water fit to drink or use by removing salt, particles and contaminants, from reverse osmosis and distillation works that take salt from seawater to filtration, disinfection and other purification trains used by towns, ships and households. An invention belongs here when the cited article describes it as a way of treating, purifying or desalinating water. Water supply works that only store or carry water belong with civil engineering, and shipboard ballast water systems belong with marine engineering.
