Pre-take care of the water before chlorination, utilizing possibly a filtration or sedimentation process to lower turbidity. This should preferably be throughout the utilization of coagulation/flocculation with Alum, then sedimentation.
However, for UV, the water needs to be crystal clear or pure so which the UV rays can penetrate the water so can thoroughly do disinfection. So For those who have water significant in iron, manganese, and odors, UV isn’t definitely proper.
The good thing is, chlorine is simple to eliminate from water with activated carbon.
