$0.035 to clean 10 liters of water is very good. $35/kilo doesn't seem unreasonable given that chlorine itself is $16-$22 a kilo through consumer stores.
Given that these are pretty gnarly chemicals in bulk, I don't think you want users handling them. Training users on PPE and procedure and supplying the PPE is a whole mess.
I have no idea where you got $3 from.
- engineer_22 6y agoDon't really need any special ppe for hypo and ferric. They're common industrial water treatment chemicals, meaning they're handled daily by low skilled workers without much news of accidents. There aren't even any special containment requirements for small quantities <500 gallons. Crystalized these chemicals are very stable and represent low risk to operators. As a yard stick of cost: surface water treatment costs somewhere in the neighborhood of $1/1,000 gallons in the developed world.
