Coagulation & Disinfection
Dear Mr. Hussein Ibrahim,
Your question carries basically two concerns
- Turbidity
- Pathogens
Turbidity , could easily be catered by any suitable coagulant such as Alum mostly used in rural areas and is commonly used by them as well for such purpose for settling the suspended particles. This could be done even for ponds, shallow channels as well. Alum is very effective for removal/settling quickly the turbidity.
Pathogens/Bacteria
For this, commonly and cheapest disinfectant is NaOCl , Sodium Hypo Chlorite. Easily available in market even in rural areas and most cheapest one and very effective disinfectant.
The above two options could be carried out in rural areas for a safer drinking water in a broader spectrum. The dosage of both i.e. Alum and NaOCl could easily be determined by the size of the pond or length (depth) of Channel.
Thank you
Best regards,
