Question

Write a short note on the liquid waste from domestic activities.

Answer 1

Hint: Wastewater, fats, oils, or grease, used oil, liquids, solids, gases, or sludge, as well as dangerous household liquids, are all examples of liquid waste. These are liquids that are dangerous to human health or the environment. They can also be discarded commercial products such as cleaning fluids or insecticides that are categorized as “Liquid Industrial Waste,” or manufacturing process by-products.

Complete answer :
Because it is so difficult to deal with, liquid waste is such an essential category of waste management. Liquid wastes, unlike solid wastes, are difficult to collect and remove from the environment. Liquid wastes spread out and can easily pollute other liquid sources if they come into contact with them. This form of garbage can also be absorbed by soil and groundwater. This pollution subsequently pollutes the plants we eat, the animals in the ecosystem, and the humans who live in the pollution’s path.
Domestic wastewaters are the liquid wastes from residential areas that are commonly referred to as domestic wastewaters in urban areas. These wastewaters are generated by our daily activities, such as meal preparation, washing, bathing, and toilet use.
Domestic houses having access to a piped water supply, as well as business premises and different institutions present in residential areas, such as schools and health centers, create blackwater and greywater. Sewage is a term that refers to a mixture of all of these sorts of liquid waste, as well as surface run-off.

Note :
Sewage is collected in underground sewers that transport the effluents to sewage treatment plants in numerous cities across the world. Before being discharged into a river or lake, sewage is cleansed at treatment plants using a variety of physical and biological methods. It's possible that the treated water might be reused, usually for irrigation.
