The adoption of low-cost sewage treatment that would simultaneously facilitate, the selective reuse of treated effluents for agricultural and industrial purposes, will be "the largest challenge in the water and sanitation sector over the next few decades."
To stop the spread of diseases, sanitation systems must adhere to strict hygienic standards. Recovering nutrients and water resources for use in agricultural production, and lowering overall user demand for water resources are two further treatment objectives of wastewater treatment.
Let’s understand why wastewater is a problem!
Wastewater Treatment Problem
The practice of releasing untreated wastewater and the increase in urban migration, are the main causes of problems with water sanitation. Uncontrolled urban growth has made it incredibly difficult and expensive to plan for, and expand sewage and water infrastructure. It is also challenging to pay for any water system modifications, because many people relocating to the city have modest incomes.
300 million urban residents in developing nations lack access to sanitation, and those most impacted by the absence of sanitary facilities are typically those with low incomes. In the developing world, two-thirds of the population lacks access to clean ways to dispose of excreta, and many more people lack sufficient ways to dispose of all wastewater.
Is discharge of untreated wastewater a common practice now?
Untreated sewage is frequently dumped straight into bodies of water or spread across farmland, posing serious health and financial dangers. Even though more homes now have access to a drinking water supply, just 5% of those homes are connected to an urban sewage collecting system. Inadequate medical care can have negative repercussions on a community's health, culture, and economy.
Effect of wastewater
Through ingestion or direct physical contact, water contaminated by human, chemical, or industrial pollutants can result in a multitude of ailments. Dengue, filariasis, malaria, onchocerciasis, trypanosomiasis, and yellow fever are among the illnesses, associated with water.
Therefore, the availability of clean drinking water and the proper disposal of human waste, have a greater impact on a country's growth and public health than any other sort of intervention.
How wastewater is damaging to the environment?
The environment may suffer a great deal from untreated wastewater. We are practically emptying our water supply because we are making water unusable.
The dangerous substances, such as heavy metals, pathogens, poisonous chemicals, oil and grease, sludge, and organic and inorganic elements, are subsequently poured into our existing bodies of water, contaminating them.
Both humans and a vast array of wildlife, including hundreds of species of aquatic fish, are at risk from this process. Additionally, the soil may get contaminated by these toxic compounds, producing fewer crops more slowly.
Small levels of water waste and pollution are not a problem for nature at all. But if we didn't treat the trillions of gallons of wastewater and sewage, generated every day before releasing it back into the environment, it would simply be overrun.
To eliminate up to 99% of all contaminants from wastewater, wastewater treatment plants nowadays are enormous, complicated facilities that employ a variety of technologies.
Before the residual water, known as effluent, is released back into the water cycle, wastewater treatment is a technique used to remove impurities from the water. The effluent has a manageable environmental impact, when added back into the water cycle or can be recycled for a number of uses.
