Water purification technologies
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from water. The goal is to produce water fit for human consumption (drinking water), The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.
Advantages / Benefits
Effective in improving drinking water quality
Contribute to substantial health gains in populations using them
May create profitable local enterprises (manufacturing and distribution) that will contribute to the economic sustainability of the technology and benefit the local economy
After the water has been purified
Furthermore, these technologies do not require a lot of energy to maintain as the chemical process itself is simple
