My water has a COD level of 30,000; how much ferrous sulfate and hydrogen peroxide should I add?
If the removal rate is about 50%, 【Ferrous sulfate heptahydrate, 18 g/L； Hydrogen peroxide: 45-60 ml/200 ml】 It’s best to conduct a few tests first and compare the results in order to determine a reasonable ratio based on both effectiveness and cost considerations
It still depends on the specific water quality and your treatment requirements; it’s best to conduct small-scale tests on water samples
You need to consider your requirements for water quality; the theoretical data from pilot tests should be increased by 10%
If you add a COD precipitant (a type of composite flocculant) to Fenton’s reagent, it is likely to **reduce your operating costs**, and it will also provide good resistance to large fluctuations in water quality.
The inlet COD is 30,000; the Fenton process isn’t suitable in this case! The amount of sludge is astonishingly high~
I offer competitive prices for ferrous sulfate here; we can work together. QQ: 961748201, Phone: 15961751517
With the Fenton process, iron sludge is a major problem. Now, dealing with heavy metals is also quite challenging.
First, it is necessary to determine what your current wastewater treatment process is like, what the required discharge standards are, and where the treated water will be used. After that, decide on the amounts of various chemicals to be used and conduct experiments!
