Answer:
1)Aeration:-Aeration is the process by which air is circulated through, mixed with or dissolved in a liquid or substance.
2)Aerobic bacteria:-An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment.
3)Anaerobic bacteria:-Anaerobic bacteria are found today that generate energy by the oxidation of iron Fe2+ compounds to Fe3+, as well as others that generate energy by oxidizing sulfur compounds.
4)Biogas :-Biogas is a mixture of gases, primarily consisting of methane and carbon dioxide, produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste and food waste. It is a renewable energy source.
5)Contaminant:-any substance that makes something dirty or not pure
6)Sanitation:-Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage.
7)Sewage:-the waste material from people’s bodies that is carried away from their homes in water in large underground pipes (sewers).
8)Sewer:-an underground pipe that carries human waste to a place where it can be treated.
9)Sewerage :-the provision of drainage by sewers.
10)Sludge:-Sludge is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, wastewater treatment or on-site sanitation systems.
11)Wastewater:-Wastewater is generated after the use of fresh water in a variety of applications, and usually involves leaching, flushing, or washing away waste products and nutrients added to the water during these applications.
