Wastewater treatment benefits
In the following text, we will provide you with the benefits of sewage treatment to gain a full understanding of these steps:
Environment
- Water Resources Conservation: Wastewater treatment helps to recycle and reuse water, which in turn leads to the conservation of
freshwater resources.
- Reduce water pollution: Sewage treatment prevents pollutants from entering water sources such as rivers, lakes and groundwater.
- Water ecosystems protection: Wastewater treatment helps to maintain health and biodiversity of aquatic ecosystems.
- Unpleasant odor reduction: Sewage treatment removes unpleasant odor from the sewage.
Public health
- Reduction of water-related diseases: Sewage treatment prevents the spread of water-related diseases such as cholera, diarrhea and hepatitis A.
- Improving the quality of life: In general, sewage treatment increases the quality of life by promoting public health and the environment.
Economy
- Reducing water treatment costs: This wastewater treatment helps reduce the costs of drinking water treatment.
- Job Creation: The wastewater treatment industry provides new jobs.
- Fertilizer production: Waste sludge from wastewater treatment can be used as organic fertilizer in agriculture.
- Energy Generation: Methane gas from wastewater treatment can be used to produce electricity.
Other benefits
- Reduce the use of chemicals: This treatment helps to reduce the use of chemicals such as chlorine for water sterilization.
- Reduce waste volume: Waste treatment reduces solid waste volume.
Wastewater Treated Applications
- Agricultural irrigation: Treated wastewater can be used to irrigate agricultural lands.
- Green Space Irrigation: This water is treated for greenery such as parks and sports fields.
- Industry: Treated wastewater can be used in some industries such as refineries and power plants.
- Underground table feeding: Wastewater treated water is suitable for feeding underground tables.
Newest Sewage Treatment Method
In addition to traditional wastewater treatment methods, including primary treatment, secondary treatment and advanced treatment,
modern and advanced methods are also applied to treat wastewater, which have many advantages such as high efficiency, greater stability
and environmental compatibility. Following the text, we describe the newest sewage treatment method in different methods:
Sewage treatment using membrane
- Filtration with automatic variables (AVF)
This method is one of the newest wastewater treatment methods, which performs the separation of pollutants at very high speed
without any chemical compounds.
- Reverse osmosis filtration (RO)
This method is used for final treatment of wastewater and producing potable water.
- plasma wastewater treatment
In this method, plasma radiation is delivered to the wastewater, without any chemical external material. Plasma radiation releases to sewage,
the O and OH radicals that decompose contaminants.
- fuel cell wastewater treatment
In this method, a special type of microorganism is used called an electric exergy that oxides organic matter in wastewater and leads to
electricity generation. In addition to wastewater treatment, this method produces electrical energy.
- Thermal hydrolysis
In this method, the wastewater is treated at high temperature and pressure, resulting in the decomposition of the organic and sludge sewage.
This treatment method greatly reduces the produced sludge and produces biogas that can be used as energy source.
- biosorption
In this method, specific biomass is used to attract the pollutants. This method of wastewater treatment is a natural and environmentally friendly method.
Advantages of Modern Methods of Wastewater Treatment
- High efficiency in wastewater treatment
- More sustainability and environmentally friendly
- High quality of refined water production
- sludge reduction
- Electric power generation
- Reducing sewage treatment costs
