Water treatment with emphasis to magnetic separation methods
نویسندگان
چکیده
One of the most important natural resources is the water. Surface and ground waters are the main sources and there are several differences between them. We need not only water in adequate quantities to cover the human necessities but also we have to develop systems that deliver a good quality of water. The majority of human uses require fresh water. However, in water sources there are several undesirable contaminants. A conventional water treatment includes the processes, flocculation, coagulation, sedimentation, filtration and disinfection. In some cases, a serious issue that we have to deal with is the hardness of water. In this paper we study the effect of magnetic fields on the removal of calcium carbonate which is responsible for the water hardness.

متن کاملA New and Efficient Method for the Adsorption and Separation of Arsenic Metal Ion from Mining Waste Waters of Zarshouran Gold Mine by Magnetic Solid-Phase Extraction with Modified Magnetic Nanoparticles
Widespread arsenic contamination of mining wastewater of Zarshouran (West Azerbaijan province) has led to a massive epidemic of arsenic poisoning in the whole of surrounding areas. It is estimated that approximately all agriculture fields are being irrigated with the water that its arsenic concentrations elevated above the World Health Organization’s standard of 10 parts per billion. A novel ad...
متن کاملMagnetic Separation of Giardia Cysts from Water
Background: Giardia is one of the infectious agents that can be transmitted by surface water and cause a disease. We designed and fabricated a magnetic system to separate the giardia cysts from water. Materials and Methods: In this study, giardia cysts were concentrated by sucrose floatation method. The cysts were mixed with physiological saline and their concentration was adjusted to 100,000 c...
متن کاملSynthesis and characterization of chitosan-magnetic iron nanoparticles
Absorption is a common technology used for water and wastewater treatment since it is often fast and efficient, while costly at the same time. Therefore, the development of low-cost and efficient adsorbents has led to the rapid growth of research interest in this regard. Chitosan is a natural polyaminosaccharide with effective adsorption properties, which is applied to remove various pollutants...
