Optimal conditions for feton oxidation
Thread Content
According to our company’s 6-month-long Feton experiment, Feton can significantly improve the biodegradability of wastewater and reduce the COD level in it. The optimal conditions are a pH of 3 and a reaction time of 1 hour. As for the ratio between ferrous ions and hydrogen peroxide, this information is kept confidential.
For different water qualities, the optimal operating conditions for the FETON reagent vary; stop trying to deceive people. Additionally, the PH value is 3; do you need to adjust the pH of the wastewater to 3 using acid first and then bring it back to 6-9? Have you considered the costs associated with such operations?
There’s nothing to keep secret – it varies depending on the conditions of the wastewater, but it’s generally between 1:10 and 1:2. This information can be found in many sources, and the testing is also very simple.
The conclusion that Feton can achieve its best results under acidic conditions is correct!
It seems the original poster knows how to take proper precautions. However, water with different compositions yields different results, and specific experiments are needed to determine this
LZ, you should explain what kind of wastewater you are using this method to treat, what the quality of the incoming water is, and what the quality of the water is after treatment In fact, this method has been used as a pretreatment technique for many types of wastewater, with varying degrees of effectiveness. As for the ratio between the two components, it varies depending on the nature of the wastewater, as the components present differ and thus the amount to be added also changes. The same principle applies to pH levels; there’s nothing complicated about it. By conducting proper experiments, many of these so-called \"secrets\" can be resolved.
Does it need to be kept confidential? Those who want to use Fenton for pretreatment will naturally conduct experiments on their own using water samples. This post was last edited by johncom on 2009-4-1 14:39.]
There are many papers on the use of Fenton’s reagent for chemical oxidation; it also depends on the properties of the water to be treated, so it cannot be generalized
1. At PH=3, it’s unnecessary (too wasteful); a PH of 4.0–4.5 is sufficient. Of course, the process must be carried out under acidic conditions. 2. The ratio of COD:H2O2:Fe2+ is not fixed; it depends on the molecular structure of the pollutants entering the water. Conducting some preliminary tests will help determine the appropriate ratio (a common ratio is 1:1.1:0.8)
