In wastewater engineering, wastewater or sewage is a combination of residential, commercial, industrial and other public places. It can make negative changes in our environment and humans.
Before its treatment, you need to take care of its composition and its quantity involved in these waster water. Because there would be different contaminants involved at different degrees. For this, you need to do a study on the properties of wastewater.
The characteristics of wastewater water can be classified into physical characteristics, chemical characteristics and biological characteristics.
Physical characteristics of waste water
|1||Colour||Natural decay of organic waste materials. Domestic and industrial wastes are most common.
Normally brown and yellowish in colour.
|2||Odour||Decomposition of wastewater.
Sewage commonly has more odour.
|3||Solids||Domestic and industrial water, Erosion of soil, infiltration|
|4||Temperature||Industrial wastes, domestic wastes.|
Chemical characteristics of wastewater
|2||Fats and oil||Domestic and commercial, food and petroleum materials.
|4||Surfactants||Domestic and industrial|
|1||Alkalinity||Domestic wastes, groundwater infiltration
|2||Chlorides||Water softeners, groundwater|
|3||Heavy metals||Industrial Wastes|
|4||Nitrogen, Ph etc..||Determination of ph|
Biological Characteristics of water
|1||Animals||Open water Sources|
|2||Plants||Open water sources|
|3||Protista||Domestic water sources|
