Because of the global increase in the use of nanoparticles, in consumer and pharmaceutical products for example, it is expected that they will increasingly become a source of environmental (air, soil and water) contamination. In the study, the researchers used aqueous solutions that contain trace quantities of five common medications, including two compounds that cannot be removed using conventional methods, to test their new technique. As per guide lines of USEPA, maximum contaminant level of arsenic in the drinking water should be .ppm [ ]. The removal capacity of PP-IM is better than the compared literature values which clearly indicates the good removal potential of … Since 2003, Danny has worked as a researcher on the Water Treatment team. The enhanced nanoparticles were tested on emulsions made in the lab with model oil as well as crude oil. Palladium Nanoparticles Can Be Used to Catalyse the Conversion of the Harmful Nitrate in Drinking Water to Nitrogen. Researchers from ETH Zurich have created a new approach to remove chemical substances from water using multiferroic nanoparticles that induce the decomposition of chemical residues in contaminated water. Peng et al. “Pollution Magnet: Nano-Magnetite for Arsenic Removal from Drinking Water”. 0000005337 00000 n In both cases, researchers simply added nanoparticles into the emulsions, which they shook by hand and machine to break the oil-water bonds and create oil-nanoparticle bonds in their place. If Carefully Controlled in Their Size, the Treatment with Nanoparticles Removes Nitrogen, Producing Only Little Ammonia Due to the excessive use of fertilizers, our groundwater is contaminated with nitrates, which pose a problem if they enter the mains water supply. The objective of the research is to determine the occurrence of nanoparticles in drinking water sources, and also study the removal of these particles in existing drinking water treatment processes. Removal of ZnO and CuO Nanoparticles from Water Using an Activated Carbon Column Journal of Environmental Engineering, Vol. 0000002640 00000 n 0 0000002295 00000 n Techniques such as coagulation and flocculation are commonly used for the removal of particles from water.
