The use of Iron oxide magnetic nanoparticles (ferro fluid) as new coagulant for water and wastewater treatment

Coagulation is important unit processes for water treatment. Coagulation destabilizes colloidal impurities and transfers small particles into large aggregates and adsorbs dissolved organic materials onto the aggregates, which can then be removed by sedimentation and filtration. A wide range of coagulants can be used for water and wastewater treatment. The most common coagulants used include ferric sulphate, aluminium sulphate, and ferric chloride. As water pollution Increases and the standards of drinking water Supply and wastewater discharge become stringent, more efficient water treatment chemical reagents need to be developed in order to achieve higher treated water qualities. Such water treatment reagents should ideally be able to disinfect microorganisms, partially ideally be able to disinfect microorganisms, partially degrade and oxidise the organic and inorganic impurities, and remove colloidal/suspended particulate materials and heavy metals. In this study we introduced Iron oxide magnetic nanoparticles (INOPs) (ferrofluid) as a new coagulant for water and wastewater treatment
