The waste water treatment technology ::
In the whole treatment process of the sewage /waste water treatment , the most important treatment technology and the key process is a kind of electrochemistry process /method called “High-voltage pulse electric flocculation treatment”,which is the newest technology in the world .
We have built many plants in China ,and overseas with this kind of technology ,we get reputation from the goverment and our customers.
we thanks to the domestic and foreign experts for treatment technology guidence, We strive to be the most advanced envrionmental protection supplier .
The water treatment advantages of the the chemistry technology:
1.much more efficient on the removal of COD and heavy metals,reduce zinc,chromium, nickel, copper, and other heavy metals to under 0.2-0.1 ,superior to the domestic similar product the level,
2.Up to 90% removal of Chromium, zinc, iron in the Electroplating wastewater ,which contains many kinds of metal ions;
3.Up to 70% removal of COD,90% of suspended solids;
4.Up to 80%-90% removal of Pigment wastewater of printing and dying ;
5.Generates minimum sludge, hence less handling of sludge;
The water treatment features of this newest “high-voltage pulsed electric flocculation”technology :
1.The technology using high pressure pulse electrochemical flocculation water treatment principle, producing Fe 2+, Fe3+ Al3+,and other metallic ion, which will lead to redox reaction to the organic or inorganic in the wastewater;
2.then the pollutans and heavy metal ion condense, to Separated and sediment from the water.
3.Still, In electric coagulation process, the anode and the cathode surface constantly produce oxygen and hydrogen, so the tiny air bubbles escape, the air bubbles can adhere to flocculate and oil content in the waste water, then float to the surface of the water, lead to air flotation effect.
4.In addtion,electric coagulation reduce the content of BOD ,COD,SS.in the waste water.
How to reduce and and removel heavy metals??? that is the following:
Fe3+ +3OH-→Fe(OH)3↓
Fe2+ + 2OH- → Fe(OH)2↓
4Fe(OH)2 + O2 + 2H2O→4Fe(OH)3↓
Zn2+ + 2OH-→Zn(OH)2↓
How to remover COD???,the following is answer:
Fe-2e→Fe2+
4OH- - 4e→2H2O + 2O → 2H2O + O2↑
Oxygen has a strong oxidation ability, can removel oxidized organic or inorganic compounds in the water, remove the COD in the water.

The water treatment capacity is 0--10 tons per hour.
