Conclusion
Both UV
and ozone play critical roles in drinking water purification, offering
effective, environmentally friendly solutions for different scenarios. While UV
is best suited for straightforward microbial disinfection, ozone excels in
oxidizing complex contaminants. Selecting the appropriate technology—or
combining both—depends on the specific water quality, treatment goals, and
budget.
