Post treatment of Water for Human Consumption for Removal of Toxic Compounds - Mini Review
Journal Title: Advances in Clinical Toxicology - Year 2019, Vol 4, Issue 2
Abstract
The treatment of water for human consumption uses chemical /physical/biological processes to guarantee the potability and to avoid contaminations due to toxic compounds. The treatment of drinking water employs the following principal processes: 1) coagulation/flocculation/ sedimentation for removal of suspended particles, generally using aluminum sulfate flocculant due to the low cost and wide application range, however in high concentrations it is toxic for humans, after; 2) rapid filtration is performed to remove the remaining suspended particles via mechanical action, and activated carbon is also used to remove chemical compounds via adsorption, however, it is possible that particles and chemical compounds are not retained; 3) as last step the adjustment of pH, the addition of chlorine and fluorine, but, the reaction of chlorine with the residual carbon can generate trihalomethanes, which is also toxic to humans. In view of this scenario, this mini article aims to present in a resumid way: a) the possible toxic substances present in water for human consumption and b) an efficient method for post-treatment water in your home.
