Several factors contributed to the elevated levels of water pollution in the earth surface increasing the risk of wastewater pollution. Inorganic metal irons and suspended liquid metals are also leads cause of water pollution. Physical treatments for water treatment include the use of effective membrane filters in two ways. Small membrane filter and large membrane filters also used for commercial applications. Different types of nanoparticles are used for the treatment of organic contaminants suspended in the wastewater. The adsorption of a reactive dye through the hydroxyapatite (HAP) leads the excellent filtration of ions in the wastewater. Different types of photocatalytic reactors are used for the treating the large amount of wastewater in effective ways. These included the titanium based photocatalytic reactors that employed the sub-micron TiO2 particles from the treated water which accompany the treatment process. Polymer composites are used for removal of wastewater due to their low operating temperat Nanofiltration also used for removal of wastewater due to the formation of utilizing of the semipermeable membrane allows the fine removal of the different ions and different types of pollutants ure and susceptibility to environmental degradation as compared to other operations.
