Rwec High Frequency Coaxial Electrocoagulation Wastewater Treatment System 1
1, electric coagulation of the technical background:
Cohesion is most important in the treatment of physical and chemical operating methods. We used to use the rally to describe the instability of the small particles of liquid in the integration of larger particles that coagulation process. Liquid contaminants: such as heavy metals, organic and inorganic solutes are basically charged state in solution. Schulze has pointed out in 1882, joined with the liquid and dissolved ions of opposite charge, Shi Rongjie agglutination unstable objects to sedimentation and filtration methods can be removed. There are many ways to reach the purpose of cohesion, chemical cohesion is one of the methods used. But because this approach expensive and produce large amounts of sludge, it is now rarely used. Biological methods due process more complex and difficult to widespread use. The electro-coagulation system is the use of electrochemical principles, under the current dissolution of soluble electrodes, making it with the charged ions, releasing electrons. Ion and water generated from the resulting from the (OH-) combined to produce a flocculation compounds. Also with the release of positively charged electron reduction of pollutants, so as to achieve the purpose of removal of liquid contaminants.
Electrocoagulation can be a complete oxidation, reduction, flocculation, flotation process, is a good treatment option. However, there are about general Electrocoagulation issues:
1) in wastewater treatment, to achieve better treatment effect, will require a longer residence time, which for the larger volume of sewage treatment works hard to apply;
2) high concentrations of organic wastewater treatment, the electrode consumption of relatively large, resulting in higher operating costs;
3) The solubility of some relatively strong material, removal of limited stand-alone hard to meet emissions standards.
Because of these several issues, so almost no one electronic device can be independently flocculation with complex water pollutants or independent as a liquid purification equipment.
Second, RWEC high frequency coaxial Electrocoagulation System
High Frequency Electrocoagulation Electrocoagulation in the traditional technology based on the invention. In-depth study of the different pollutants in a variety of field conditions, the electrochemical reaction occurs and results, the summary of the use of power level, the size of the current density, the power of the form (such as DC, pulse and frequency of high and low) various sensitizers occur at different electric field induced oxidation of the role of electrode shape, the researchers invented the flocculation RWEC coaxial reactor and equipped with intelligent power RW RWEP adaptive high frequency with axis Electrocoagulation system.
High Frequency Electrocoagulation Electrocoagulation difference between traditional and features:
1) The power to change the traditional form of flocculation reactor electrodes: the electric current can be found in addition to several coagulation electrode, there are bed flocculation, flocculation ducts.
2) General Electric flocculation using matching power supply for the DC power supply, pulse power, high voltage power supply or high frequency power supply. The high-frequency coaxial Electrocoagulation uses a high voltage pulse and the high and low frequency adaptive intelligent power supply. This kind of power within a certain range, can be processed liquid load (water quantity and pollutant content) were automatically adjusted. This can not only achieve a certain contaminants in liquids or substances for the removal or extraction, also sewage treatment or water purification works completely automated.
3) According to the processing of requests, you can call the process of flocculation by adding an appropriate amount of “sensitizer.” As the high-frequency coaxial flocculation in a completely closed space, and therefore in the high-frequency electric field, the sensitizer can be more fully “activate”, making catalytic oxidation reaction induced by a more thorough, complete the General Electric flocculation can not complete the processing.
