Thread Content
For coagulation pilot tests, what is the typical dosage of ferrous sulfate? For example, for 1 L of wastewater, how many mg of ferrous sulfate heptahydrate is appropriate to add?
Is it wastewater treatment or water treatment? The dosage varies depending on the properties of the raw water. Try again and again depending on the goal you want to achieve. Try from 25/50/100..
Ferrous sulfate generally works best when used in combination with lime. In the case of alkaline wastewater, the amount of ferrous sulfate to be added can be determined based on the pH value; additionally, the suspended solids content in the water also affects the dosage required.
