Importance of effective waste Water Management
Clean water is one of the most important natural resources on the planet because it is necessary for life. Wastewater, which is used water, is also a valuable resource, especially in areas where there are recurring droughts and water shortages. However, wastewater contains a variety of hazardous substances and cannot be released back into the environment until it has been treated.
As a result, wastewater treatment is critical for two reasons: restoring the water supply and protecting the environment from toxins. The wastewater treatment process not only produces clean, reusable water but also has the potential to produce several other advantages. It has the potential to reduce a country’s waste production, generate energy through methane harvesting, and produce natural fertilizer from the waste collected during the process.
The following is a more in-depth explanation of the advantages of wastewater treatment:
Restoring the water supply
All communities, particularly those in water-stressed areas, must ensure that good water treatment processes are in place so that treated water can be reused or returned to the water cycle, but never wasted.
Protecting the environment
Contaminants from both residential and commercial use can end up in wastewater. Chemical compounds and pathogens in wastewater, if not treated, can harm the health of animals, plants, and birds that live in or near water. It can also contaminate crops and drinking water, negatively impacting human health. Wastewater treatment is critical for preserving the health of many different ecosystems.
The amount of waste that is typically released into the environment is reduced through wastewater treatment, thereby improving the health of the environment. As a result, the government reduces the health risks associated with environmental pollution as well as the water loss caused by water pollution. Wastewater treatment also reduces the amount of money spent by a country on pollution-fighting environmental rehabilitation projects.
Production of Energy
Because it contains a high concentration of biodegradable material, the sludge collected during the treatment process is treated. The gas produced during this anaerobic digestion process contains a significant amount of methane, which is extracted and burned to generate electricity. This energy can be used to power wastewater treatment plants, making them self-sustaining, and any excess energy produced can be transported into a country’s national grid. This reduces a country’s reliance on non-renewable energy sources such as fossil fuels, lowering its carbon footprint and energy expenditure.
Any biodegradable material that remains is dried in “drying lagoons” before being converted into natural fertilizer. The resulting natural fertilizer is then used in agriculture to boost crop yields. This reduces the use of chemical fertilizers, which pollute the marine and surface ecosystems.
In summary, the combination of these benefits, along with water production, makes wastewater treatment a viable short and long-term solution to the world’s water crisis, which will only worsen as the global population grows. The world’s population is expected to reach 9 billion people by 2050, increasing the amount of water that can be treated. This will result in the production of large amounts of fresh, usable water, assisting in the fight against water scarcity.
