Water purification generally means the release of water from any impurities it contains, such as pollution and microorganisms. Clean water is very one-sided process, cleaning process includes many steps. Those steps must be progress depends on the type of contaminants that are in the water. This may differ for different types of water. Settling in the process of cleaning begins some contaminants such as oil, can be handled in the sump. They can be easily removed after they have reached the bottom of the tank. Removal of dangerous microorganisms, often contaminated water must be free from microorganisms. Water than cure, usually by chlorination. Removal of dissolved solids microorganisms not purchase strattera only a threat to the water, they can also be an advantage when it comes to water treatment processes. They can convert contaminants into harmless substances. This biological treatment process usually takes a long time and it is used only for water that is contaminated with pollutants, microorganisms, usually bacteria can convert. In the treatment of microorganisms is not an option we often use different methods of treatment, called the physical / chemical treatment methods. Chemical treatment is often to deal with the addition of certain chemicals in order to ensure that the structure of pollution and changes can be removed more easily. Fertilizers, such as
removed this way. Removal of contaminants can be done through more difficult specific chemical processes. It requires a lot of education to fully understand this stage of purification. Physical treatment usually deals with the purification steps, such as. For more information on water pollution treatment process more detailed description of bacteria and other microorganisms are removed from water by disinfection. This means that some substances are added to kill bacteria, called biocides. Sometimes disinfection can be done with. For more information on When bacteria are used for water purification are two types of transmission, one of which is aerobic transfer. This means that bacteria that are dependent
transformation of pollutants in water. Aerobic bacteria can convert the connection when a large amount of oxygen present, because they need to perform any type of chemical transformations. Usually the products they make pollutants are carbon dioxide and water. When bacteria are used for water purification are two types of conversion, one of which is anaerobic transfer. This means that bacteria are not oxygen dependent conversion of pollutants in water. Anaerobic bacteria can convert only when the oxygen level is low, because they use other types of substances for chemical transformations. Anaerobic bacteria do not only develop carbon dioxide and water during the conversion, but also methane. It can be used to save a mechanism that supports the cleaning takes place. Anaerobic conversion of substances require more steps than aerobic conversion, but the end result is often less satisfactory. After anaerobic conversion usually aerobic bacteria (bacteria that make use of oxygen) still need to complete the process because the water is clean enough yet. Fertilizers such as phosphate removed by addition of another chemical, usually. Matter than are solid precipitation that can be filtered from the water. Removal of ammonium nitrate and a little more difficult is the process of cleaning, which is aerobic and anaerobic transformation to remove them. In the aerobic conversion stage there are two types of bacteria involved. Nitrosomonas bacteria that convert ammonium to nitrite and Nitrobacter bacteria that convert nitrites to nitrates after that. Although nitrates do not pose a direct threat to the health of many fish, a high level still undesired. In addition to encouraging abnormal extensive algal growth, now it is believed that high levels of nitrates are involved in certain diseases of fish. This means that the process can be stopped here. Anaerobic bacteria take over, they convert nitrates into atmospheric gas. This process occurs only in the absence of oxygen. In the first phase reverse process of nitrification, it converts nitrates into nitrites ago. The second stage of denitrification converts nitrite to nitrogen (N
). This gas can be freely released into the atmosphere without causing environmental damage. For water terminology check out our or return to New! . << >>
