COD Removal Magnetic Fenton Package System for Industrial Waste Water Treatment
Fenton reaction: Under acidic conditions, H202 reacts with Fe2+to produce hydroxyl radicals, which can rapidly oxidize and decompose recalcitrant organic compounds.
Our Magnetic Fenton Package System magnetize water molecules to rearrange them in the direction of magnetic field lines, greatly increasing the efficiency of hydroxyl radical oxidation and decomposition of COD. This can decompose most difficult to degrade organic compounds into carbon dioxide, water, and simple organic compounds

Chemical process principle of Fenton
Under acidic conditions, H2O2 reacts with Fe2+ to produce hydroxyl radicals, which have strong oxidizing ability to quick oxidize and decompose the organic matter which is difficult to degrade.
Reaction equation: H202+Fe2+ →Fe3++OH-+·OH
Fe2+ is catalyst, H202 is oxidant, ·OH is hydroxyl radical, and the amount of hydroxyl radical generation is determined by Fe2+ and H202. Fenton’s key point is the oxidizing ability of hydroxyl radicals, which have two path after they are produced:
1. It does not contact pollutants and decomposes naturally, causing waste;
2. Contact to pollutants and oxidation.
Improving the oxidation efficiency of hydroxyl radicals is the R&D direction of all Fenton process manufacturers.

How do we improve oxidation efficiency
When waste water passes through the magnetic field area at a certain flow rate, the paramagnetic water molecules are rearranged according to the direction of the magnetic field lines, thus changing the binding state of dissolved and colloidal organic pollutants and water molecules in the waste water, and balance of water molecular groups is broken. Thus increases the probability of collision between pollutants and hydroxyl radicals, significantly increasing the speed and extent of chemical reactions.
Magneto Fenton Process use fixed-point removal method to oxidize COD , H202 consumption is extremely low, 40% cheaper than traditional Fenton.
Firstly magnetize the wastewater, change the arrangement position between pollutant molecules and water molecules, so that hydroxyl radicals can easily contact COD
