What is Sewage Treatment?
Sewage treatment is the process of eliminating pollutants and toxic substances from domestic wastewater, which includes sewage from toilets, bathrooms, kitchens, and other sources. This sewage must be cleaned properly before being discharged into the Environment through sewers.
Various physical, chemical, and biological methods are used to treat sewage before it may be considered environmentally benign.
What is the Importance of STP in Apartments?
More than 10% of the world's population consumes foods irrigated with untreated wastewater from homes, according to the World Health Organization (WHO).
What difference does this information makes to us, city dwellers, who drive luxury cars and live in swanky highrises?
It's because we may be eating vegetables, rice, and wheat grown in water contaminated with some of the world's most heinous toxins, as well as faeces and urine.
In most Indian metropolises, wastewater treatment is a dystopian nightmare. Untreated sewage from apartments and residences is, in fact, the leading cause of water contamination in India. According to a recent report by the “Central Pollution Control Board”, the majority of the sewage produced by India's 135 billion people is discharged without treatment, and the country has less than a thousand sewage treatment plants.
This is why apartment-sized sewage treatment plants (STPs) are a must-have!
Thiswill ensure that the wastewater generated by your apartment is not dumped into the environment untreated, contaminating water bodies and drinking water reserves critical to ensuring safe drinking water for all of us, including our children and grandchildren.
Another strong reason to have STP is that it is now required by new environmental legislation, which is especially important if you are not aware of the necessity of conserving our rapidly decreasing drinking water resources.
The following are the reasons behind the requirement of STPs
1: Sewage treatment is a straightforward and cost-effective procedure. It is simple to maintain and carry out in an apartment.
2: Sewage treatment plants will undoubtedly improve people's quality of life.
3: Sewage treatment plants can provide clean, reusable water that can be used for laundry, cleaning, and watering plants, among other things.
4: Because the technology is incredibly steady and efficient, the plant produces no odours or noise.
5: Wastewater treatment has become a global issue since two million children under the age of five die each year from waterborne infections. Dysentery, gastroenteritis, and cholera can all be caused by microscopic organisms found in sewage. The treatment technique can eliminate 97% of these dangerous tiny pollutants.
6: The effluent is then safely dumped into the sewage system after being treated. The amount of wastewater released into the environment from residential structures is minimized, thereby protecting the earth's most valuable resource-water!
Step 1:The wastewater is screened in the first stage to eliminate plastic bottles, wrappers, and other large items.
Step 2:Sedimentation is the first step, in which solids sink to the bottom and lighter particles, such as oil, float to the surface, where they can be easily collected with skimmers.
Step 3: Filter made of activated sludge or a filter that has been treated to allow anaerobic bacteria to absorb biodegradable soluble pollutants.
Step 4:Disinfection and elimination of nutrients and sediments in the tertiary stage. In this stage, all advanced treatments are combined to remove and reduce pathogens, nitrogen, phosphorus, and other inorganic compounds by disinfecting the water chemically, through ultraviolet light, or micro filtration, or Reverse Osmosis before releasing the sludge for reuse. The sludge is then treated in digesting tanks with anaerobic bacteria and later used as fertilizer.
By 2025, the world's population is expected to reach a staggering 8 billion people. With the current water supply, supporting so many people on Earth will be difficult. As a result, the wastewater treatment procedure becomes even more critical. Taking spent water, filtering away dangerous impurities, and returning safe, clean water to the source might also alleviate future water shortage concerns.
