“…Water pollutants are categorized into point source, where the pollution originates from a single and identifiable source, and nonpoint source, where pollutants originate from a variety of sources [20]. Based on their main physicochemical characteristics, they can also be classified into radioactive, thermal, microorganism, nutrient, suspended solid and sediment, and organic and inorganic pollutants [21]. Inorganic pollutants consist of heavy metals, fertilizers, sulphides, ammonia, oxides of nitrogen, acids, and bases [22][23][24].…”

Research on contamination of groundwater and drinking water is of major importance. Due to the rapid and significant progress in the last decade in nanotechnology and its potential applications to water purification, such as adsorption of heavy metal ion from contaminated water, a wide number of articles have been published. An evaluating frame of the main findings of recent research on heavy metal removal using magnetic nanoparticles, with emphasis on water quality and method applicability, is presented. A large number of articles have been studied with a focus on the synthesis and characterization procedures for bare and modified magnetic nanoparticles as well as on their adsorption capacity and the corresponding desorption process of the methods are presented. The present review analysis shows that the experimental procedures demonstrate high adsorption capacity for pollutants from aquatic solutions. Moreover, reuse of the employed nanoparticles up to five times leads to an efficiency up to 90%. We must mention also that in some rare occasions, nanoparticles have been reused up to 22 times.

“…In addition to organic pollutants, inorganic pollutants are also common in discharged effluents from various industries. These include heavy metals, sulfates, cyanides, mineral acids, etc and can pollute water if available in higher than permissible limits [89]. Removal of toxic heavy metal ions is crucial to ensure their safety to humans and the environment.…”

Worldwide, the scarcity of water due to the contamination of water and water resources from human activities has become a challenge. To overcome this, we need adequate water treatment technologies. For the past few decades, research has becoming wider to innovate the advanced technologies for water purification. Several conventional methods have been adopted for water treatment. Extensive investigations have been done, and some are still in development to find an eco-friendly and feasible process for water purification. The advent of membrane separation processes has changed the scenario in the field of desalination and water treatment. The proper selection of membrane material and configuration could be an excellent approach towards water purification. This chapter deals with the various advanced functional membranes, the functionalization of membranes employed in UF, NF and membrane distillation. This chapter also deals with their applications in wastewater treatment.
