Electrocollection is the process of destabilizing suspended, emulsified or dissolved contaminants in an aqueous medium by introducing an electrical current into the medium. The electrical current provides the electromotive force to drive the chemical reactions. When reactions are driven, the elements or compounds will reach its most stable state. Generally, this state of stability produces a solid that is either less colloidal and less emulsified(or soluble)than the compound at equilibrium values. As this occurs, the contaminants form hydrophobic entities that precipitate and can easily be removed by a number of secondary separation techniques.
Electrocollection utilizes direct current to cause sacrificial electrode ion to remove undesirable contaminants either by chemical reaction and precipitation or by causing colloidal materials to coalesce and then be removed by electrolytic flotation. The electrochemical system has proven to be able to cope with a variety of waste waters. These waters are paper pulp mill waste, metal plating, tanneries, canning factories, steel mill effluent, slaughter houses, chromate, lead and mercury laden effluents, as well as domestic sewage. These waste waters will be reduced to clear, calm, odorless and reusable water. In most cases, more especially domestic sewage, the treated water effluent will be better than the raw water from which it had been originated.
The succeed research of Impulse Electrocollection Automatic Wastewater Treatment System, has changed the history of wastewater treatment, it created the new science and technology for wastewater treatment. Show the impossible thing with the fact, Hi-tech changes the traditional waste treatment ways, not only heavy metal and COD removed more than 90%, in some cases we can also reuse the outflow water. The system’s advantages as follow:
