New technology industrial sized coagulation waste water treatment apparatus of the introductory article: coagulation (Electrocoagulation, referred to as EC), also referred to as a short electrolysis, is used for waste water treatment, sewage treatment industry and medical treatment. Electrocoagulation has developed rapidly in recent years because of its ability to remove emulsified oil, total petroleum hydrocarbons, stubborn organic matter, suspended particles and heavy metals that are difficult to handle with other filtration or chemical treatment technologies. Environmental protection Next, I will introduce you the new electrocoagulation technology of medical wastewater treatment equipment. There are many existing electrocoagulation equipment. From the perspective of its complexity, the electrocoagulation technology based on simple cathode and anode electrodes can regulate the electrode potential, passivation effect, anode consumption, cell redox potential, and even add ultrasound, ultraviolet light, and various Gases and reactants carry out advanced oxidation processes on recalcitrant organic substances. Combining the latest technology, reducing electricity consumption and miniaturizing power equipment, electrocoagulation systems are now an economical solution for global water treatment plants and industrial water treatment. Electrocoagulation ('Electricity' refers to the use of electric current to charge water, and 'coagulation' refers to changing the charge on the surface of particles to form polymerization of suspended solids) is an advanced and economical water treatment method. It can effectively remove micron-level suspended particles, break the emulsification of colloidal substances, and remove heavy metals without the need for filtration and additional chemical substances. Known water treatment technologies include nitrification biological treatment, denitrification treatment, phosphorus removal, and some physical and chemical treatment processes that require additional chemical agents. Commonly used physical and chemical treatment methods include filtration, air stripping, ion exchange, chemical precipitation, chemical oxidation, activated carbon absorption, ultrafiltration (UF), reverse osmosis (RO), electrodialysis, distillation, and gas stripping. Mechanical filtration can only solve two types of problems in sewage treatment: suspended particles with a diameter greater than 30 microns, and free grease. Emulsified oil and grease will cause the filter media to lose its function and cause high maintenance costs. Electrocoagulation can remove suspended particles of any size (including harmful particles and heavy metals larger than 30 microns, which will wear the pressure purification device and cause environmental and personal injury). The chemical treatment method solves the suspended particles, oils and lipids, and some heavy metals, but may require trimers and multiple pH adjustments for the next step of disposal. This type of technology requires additional chemical agents, leading to increased costs, secondary pollution and intensive labor. This type of technology additionally requires compressed air to float condensed contaminants. In principle, filtration technology is a necessary follow-up process. The electrocoagulation technology does not require filtration, daily maintenance, and no additional chemical substances. It can directly remove suspended particles, oils, lipids and heavy metals of any size. The electrocoagulation process can remove the smallest colloidal particles because the electric field neutralizes any remaining charge, making flocculation easy to occur. The electrocoagulation process generally avoids the abuse of chemical agents, so there is no step to neutralize additional chemical agents, and the secondary pollution that may be caused by the addition of high-concentration chemical agents. The bubbles produced by electrolysis usually carry pollutants to the upper layer of the solution, which is very easy to concentrate, collect and remove using mechanical fishing devices.  The electrolysis process in the electrocoagulation unit is controlled by electricity and has no mechanical parts, so the maintenance cost is extremely low. Adding sodium hypochlorite to the incoming water helps to reduce the biochemical oxygen demand (BOD) and chemical oxygen demand (COD). If the wastewater contains high levels of organic compounds or dissolved ammonium (NH4+), sodium hypochlorite should not be added to avoid the production of trihalomethanes (THMs) or other chlorinated organics. Sodium hypochlorite can be produced using an electric chlorinator. Due to the excellent removal of suspended particles by electrocoagulation and the simple and easy operation of electrocoagulation, a test conducted by the US Naval Research Institute shows that the most ideal use scenario for electrocoagulation technology for industrial wastewater treatment is as 'ultrafiltration-reverse osmosis' And 'microfiltration-reverse osmosis' multi-layer membrane treatment system pretreatment equipment. Industrial wastewater treatment electrocoagulation technology provides protection for low-pressure membranes. Electrocoagulation is also effective in removing membrane pore dirt (such as silica, alkaline earth metal hydroxides and transition metal groups), which cannot be removed by a single chemical agent.
