Water Purification Science

Water Purificationan overview | ScienceDirect Topics

Sorption is a water purification process occurring when water is pumped through a layer of granulated load material such as activated charcoals or zeolites (IAEA, 2002). It works in much the same way as a domestic drinking water filter system. Impurities in the water (such as dissolved organic molecules, ions and surface-active particles) are extracted via the process of sorption as a result of their physical and

23/04/2021· Hydrogels Water purification is an energy-intensive, multistep process used to remove contaminants such as salt, heavy metals, oils, or biological pathogens. Xu et al. designed a hydrogel that purifies water using nothing more than sunlight. Polydopamine, a melanin-based polymer, was added to sodium alginate on top of a microporous poly(N-isopropylacrylamide) (PNIPAm) hydrogel.
