What substances cannot be removed from wastewater?
Wastewater is water that is discharged from homes and businesses via sewer lines or after a septic tank has been pumped. It is the water emitted by toilets, showers, washing machines, sinks, and dishwashers. Because wastewater contains faeces, urine, household or commercial cleaners, soaps/shampoos, and other contaminants, it must be treated before it can be returned to water sources or public water supplies.
While wastewater treatment plants do this every hour of the day, there are some things that homeowners may not consider.
There are five items from homes and businesses that are extremely difficult to completely remove from wastewater.
1: Personal Care Products(PPCPs) and Pharmaceuticals
Prescription and over-the-counter medications and supplements are both polluting the environment. Even when people properly dispose of their unused medications, some of them make their way into the urine stream. The urine is then processed at a wastewater treatment plant, where the medications are not completely removed. Antibiotics and synthetic hormones (birth control) are discovered in water sources.
Triclocarban-containing antibacterial soaps are worse. These drugs and chemicals are not only ending up in bodies of water, but there is also a chance that trace amounts are in the water that returns to homes and businesses. There are fears that this will lead to an increase in antibiotic resistance.
2: Nitrates and Nitrites
Many cured meats contain nitrates as a food additive. They are commonly found in deli meats, bacon, sausage, and hot dogs. The bacteria in the body converts those foods to nitrite as they break them down. Nitrites are extremely dangerous to bodies of water because they deplete oxygen and promote algal growth.
Ammonia must be removed from the wastewater treated by a wastewater treatment plant. Nitrite is oxidized by nitrite-oxidizing bacteria, resulting in nitrogen gas.
3: Trihalomethanes
Trihalomethanes (THMs) are almost impossible to avoid in the final stage of wastewater treatment. THMs are produced as a byproduct of total organic carbons reacting with chlorine, which is used to kill any remaining bacteria. THMs are thought to increase the risk of cancer and have an impact on reproductive health if consumed in excess.
4. Hormones
Water has been found to contain hormones. One of them is estrogen. In some cases, the estrogen is derived from medications, but in others, it is derived from natural sources.
Water contains steroid hormones as well. Hormones can affect the development of fish and plants when they are released into water sources. It has been discovered that estrogen influences how plants develop flowers and germinate.
Hormone exposure reduces the number of sperm and the size of male fish testes, according to one study. It has an effect on the heart health of tadpoles.
5: Microbeads
Microbeads are tiny plastic pellets that are commonly found in cosmetics. They are intended to aid in skin exfoliation. They can be found in body washes, toothpaste, and shampoo. Larger plastics exposed to the sun and environmental forces may also degrade into tiny plastic fragments. Because the beads and pieces are so small, they frequently pass through the screening process of wastewater treatment. If they are not captured during the water treatment process, they may end up in bodies of water where fish and other aquatic species consume them.
Conclusion
The process of water purification offers numerous advantages, making it a feasible long- and short-term solution to the world's current water issue, which is only getting worse as the world's population grows. Expanding the wastewater treatment sector will result in enormous amounts of fresh water being produced, reducing water scarcity.
