Sewage treatment methods are used to remove contaminants, pollutants, and harmful materials from the wastewater. The sewage treatment methods include biological, chemical, and physical processes to remove harmful pollutants. The main purpose of using a sewage treatment method is to convert wastewater into environmentally safe sewage water, effluent. A solid waste known as biosolid or sludge is also produced which is suitable for reuse or disposal. Sewer drain pipe denver and video sewer inspection are one of the best methods for treatment of sewage system. One can visit sewerex.com to know more about these methods.
Water gets filled with harmful pollutants and contaminants since it gets used for different purposes such as farming, household works (baths, toilets, showers, kitchens, sinks), hospitals, industrial and commercial sites. Pollutants such as organic waste, bacteria, suspended solids, phosphates, and nitrates make the water extremely harmful therefore these pollutants much be removed.
In order to make the wastewater safe enough for reuse, the concentration of pollutants and contaminants present in the water must be reduced to a level or a mark and this level is usually a standard set by the Environment Agency.
Treatment of sewage can be done to where it is constructed (in sewage treatment plants or in septic tanks and their drain fields) or it is collected and transported through a system of pipes and pump stations to the municipal treatment plants.
The former method is becoming famous because of its ECO towns since 60% of the total cost of the mains sewerage is consumed alone by the pipework to transport the wastewater to a central location and also it is not sustainable. This phenomenon is known as the “Decentralisation” of sewage treatment systems.
The environmental engineers are the one who does the job of constructing and designing sewage. These engineers naturals and engineered systems of a different type in order to develop the required treatment level, using chemical, physical, sludge, and biological treatment methods. The final product is sludge and sewage water and both of these should be safe enough to discharge or reuse back into the environment.
The sludge is unknowingly filled with many toxic organic and inorganic compounds and diseases and the safety of sludge is still in doubt. There are some harmful pathogens that cannot be described by the treatment process. ‘Prion’ diseases are one of these pathogens which cannot be described by the treatment process.
The characteristics of a water treatment methods are determined by:
- The amount of treatment that is required to maintain the quality of incoming rivers and streams.
- The nature of industrial and municipal wastes that are transported to them by the sewers.
