Which technologies are used to maintain high water quality?

• A. UV sanitisation
• B. Carbon filters; Sediment filters; UV sanitisation
• C. Boiling water
• D. Distillation

Answer: (B)

Maintaining high water quality relies on a layered approach that combines filtration for particulates, chemical filtration to reduce contaminants, and disinfection. Sediment filtration removes particles that can cause turbidity and wear on equipment, helping water look clearer and protecting downstream filters. Carbon filtration tackles chemicals like chlorine and many organic compounds, improving taste and odor and reducing certain contaminants. UV sanitisation provides microbial inactivation, delivering disinfection without adding chemicals or altering mineral content. Together, they address physical, chemical, and microbial quality in a practical, balanced way for ongoing water treatment.

Boiling water kills pathogens but doesn’t remove dissolved chemicals or particulates and isn’t practical for routine treatment. Distillation removes many dissolved substances but is energy-intensive and not typically used for everyday water quality maintenance.
