Why is disinfection the last stage?
Disinfection makes sense at the end of a treatment line, not at its start. Disinfection carried out before suspended solids and organic load have been removed is both inefficient and consumes more chemical than necessary.
Where UV is chosen, the clarity of the water has a direct effect: in turbid water the light transmittance falls and the disinfection becomes less effective. That is why we position UV after the filtration stages.
