Thesis topic:
The study of changes in wastewater composition during tertiary treatment with respect to water reuse for irrigation
Motivation
Water, an important resource for human existence is increasingly becoming scarce. Water resources such as rivers, streams, lakes, springs, groundwater, etc. use for potable water distribution and other uses such as irrigation have reduced significantly in quantity. Alternative sources of water for human use are therefore imperative. Wastewater holds a promising prospect of being a viable alternative water source for human activities.
Solution
Treated wastewater for reuse (irrigation) as an alternative water source, is key to water sustainability. The study will focus on tertiary treatment of wastewater for possible use in irrigation. Emphasis will be placed on the physico-chemical parameters of the secondary effluent as it goes through the tertiary treatment process and the changes that might occur in the chemical composition.
The quality of the tertiary effluent from the tertiary treatment will be evaluated analytically with regards to irrigation and the possible impacts on crops and soil.Another area of interest
- Biological wastewater treatment
- Biological waste treatment
- Municipal solid waste and landfill management
- Biological air purification using biofilters
