First of all examine the input condition like pH,turbidity, color, smell, the bacteriologicalcontent.
With such data it would be much easier for anyone interested in helping in my opinion to advice on the best treatment process that efficient and economically feasible.
River water is mainly contaminated by physical and biological impurities consist of Totals suspended solids, turbidity, bacteria, virus, algae etc. which need to remove before supply and distribution of river water for various uses.
River water treatment is the process of removing contaminants from flowing or stagnant river water which includes physio-chemical treatment of water with the combination of conventional and advance treatment process like
- Coagulation, flocculation,
- Clarification, settling,
- Filtration
- Granulated activated carbon filtration.
- Disinfection of filter water
- If COD/BOD more, then suggested for biological treatments.
This process produce an environmentally safe and pure water suitable for drinking and multiple uses in domestic, institution and industrial application.

This is a very reasonable approach, which has been recommended by other people in this thread, too.
You may also want to tell us, which volumes you need to treat per day at one location and how many of these systems you are planning to install.
Your overall approach may also depend on the distribution system you are planning to use. Not least cultural aspects and the region you are working at may influence your choices. These would be further informations needed for a sound advice.
I am sceptical of those recommendations which just tell you to buy their device without even bothering to ask what you really need.
Be also aware of the possibility to use different water sources and different levels of treatment for different purposes. You'll certainly need potable water quality for drinking, cooking and dish washing, i.e. a minimum of 10 l/(c.d), you could be satisfied with service water of lesser quality (bathing water) for hygiene, laundry or toilet flushing, if you consider the latter at all. This could be recycled water or rainwater, if you have enough rainfall, or any other source. Don't neglect the potential of UDDT toilets to both save water and produce a valuable fertiliser.
