With the help of the coagulation process, a large number of organic compounds and particles present in water can be removed. The coagulation process also removes some dissolved organic material which is known as Natural Organic Matter (NOM) or Dissolved Organic Carbon (DOC). Coagulation is also removed to suspended particles including iron-like inorganic precipitates. If the quantity of dissolved organic carbon is extremely large in water, it gives the water a bad smell and an unpleasant taste, as well as makes the color brownish in color. Although the process of coagulation can remove the solid particles and dissolved organic matter, there are chances that the water may still contain some disease-causing bacterias and pathogens. In 1998, an international report published that with the help of coagulation and sedimentation can only remove between 32 and 687 percent of bacterias and between 27 and 84 percent of viruses. Usually, the pathogens get attached to the dissolved substance and when those dissolved substances are removed along with them the pathogens also get removed by coagulation. The septic tanks and denver grease traps used also needs treatment and denver septic tanks services and drain cleaning denver co are used for it.
Since coagulation cannot remove all bacterias and viruses present in water, therefore it cannot produce water that is safe enough for drinking. However, it is an important step that is used during the water treatment process because it removes all the solid and dissolved organic carbon which makes it difficult to disinfect the water. Since the municipal water treatment plant uses less chlorine to disinfect the water which makes it much safer to drink than water because the by-product which is produced by the reaction of chlorine with NOM is trihalomethanes (THMs) which is highly dangerous for humans. Also by using less chlorine, municipal water treatment plant saves a lot of money too.
If the chemicals are added inaccurate amounts with proper application, then the residues of chemicals left in water are not that much danger to humans. Residues are the small amount of water that got left in the water after substances are added and the treatment of water is done. The residuals got left to depend upon the coagulant that is used. Iron and chloride are added to water when ferric chloride is used. Iron and sulfate are added to water when ferric sulfate is used. Sulfate and aluminum are added to water when aluminum sulfate is used.
