The process of removing pollutants from municipal wastewater is called sewage treatment. Various processes are used in the treatment, such as physical, biological and chemical processes. It is also known as wastewater treatment. Municipal wastewater includes wastewater from domestic and industrial sources. The purpose of this waste treatment is to cause less harm to the environment being discharged. Sewage treatment usually involves three parts - primary, secondary and tertiary treatment. Primary treatment involves a sedimentation process to remove contaminants. The secondary treatment uses biological process to treat the precipitated wastewater, while the third process is the final stage to improve the quality of wastewater. This stage is also called "wastewater polishing stage".
Application of activated carbon filter in wastewater treatment - stage 3
The activated carbon filtration process basically absorbs the pollutants that are not needed in the wastewater. Activated carbon is first treated with oxygen. This helps the charcoal open millions of tiny holes. Activated carbon is very effective in absorbing pollutants in water. The filtration process includes activated carbon to remove residual pollutants from the waste water. Carbon absorbs trace pollutants, such as chlorine, methane, organic compounds, and even tastes and odors from water. Chlorine in wastewater is removed by activated carbon filter. It has a large surface area, so it can effectively absorb pollutants in wastewater. The dechlorination process is full of macropores of carbon. Therefore, impurities are removed. Activated carbon needs to be replaced because its working capacity is gradually reduced. The process involves lower operating costs. The carbon in the activated carbon filtration process also absorbs organic compounds. The ability of the process will depend on the physical properties of the activated carbon surface area, the amount of hydrogen and oxygen contained, the concentration level of impurities, the duration of treatment and, of course, the pH value of the water used. Activated carbon filtration process can also be used as pretreatment in other waste treatment processes. These include ion exchange resins and reverse osmosis processes. This combination of activated carbon and ozonation can easily remove trace pollutants. This also increases the service life of the activated carbon filter.
Benefits of using activated carbon filter
1. The efficiency of absorbing pollutants is as high as 90%
2. The filtration process is easy to operate
3. Low maintenance
4. Effectively remove chlorine, organic matter, bad taste and odor
5. Cost effective - reduces installation costs
6. It can be used in household and wastewater treatment plant
Activated carbon filtration process adopts absorption process to remove pollutants in water. This is a relatively low-cost operation and is very effective in removing harmful pollutants from wastewater. The best part of the process is that it can be easily produced anywhere in the world, with one drawback - the filters wear quickly and need to be replaced regularly.
