Hello there,
A couple of us have been tasked to come up with a way to produce drinkable water from a source which is turbid and I'm trying to figure out a way to do this. It has to be cheap and work well without needing too much knowledge to operate.
My initial idea is to use a coagulant (polyferric sulfate), flocculant (polyaluminium chloride) and chlorine dioxide tablets together to reduce turbidity and disinfect. Is this a good combination and how effective will it be? Are there better coagulants and flocculants than the ones I chose?
As for the amount of each, I looking at using 0.5mg/l of chlorine dioxide but I'm not sure about how much to use for the other two. The biggest issue with this is chlorate production but I was reading that iron based coagulants can reduce this and at the concentration of 0.5mg/l I was thinking that it won't be too much of an issue.
I would also be really interested in any alternative ideas that you guys might have (I've ruled out using the sun but I am open to something that uses electricity), the above is an initial idea that seems to be quite cheap to implement and could be used to filter 1000 liters of water for less than $2.
Advice will be very much appreciated.
Thanks for reading.
Wasn't really sure if I should post this thread in the Chemistry or Biology section, so I hope this is ok.
