Oily Sewage Water Purification Machine Electrocoagulation System Device Electrical Flocculation Effluent Coagulation Equipment Water Treatment Plant

Product DescriptionQDEVU Electrocoagulation(EC) Water Treatment PlantDescriptionElectrocoagulation(EC) or Electrical Flocculation technology is a sewage treatment method that breaks the stable state of suspended solids, emulsified or dissolved pollutants in water by introducing direct current into the water.  Compared with traditional chemical flocculation, electrical flocculation is an efficient and environmentally friendly water treatment technology without adding chemical or adding a small amount of flocculant, with low operation and maintenance cost, stable treatment effect and no secondary pollution of water quality and sediment.Electrocoagulation Dissolved Air Flotation (EC-DAF) Plant is a combination of electrolysis, flocculation and air flotation, which can remove all kinds of impurities in wastewater, like COD, BOD, oil,turbidity, suspended solid, biochemical degradation, heavy metal ions, chroma, calcium, magnesium ions,SiO2,colloidal silicon, organic silicon,bacteria and viruses,etc. Working PrincipleElectrocoagulation technology using electrochemical principle, such as aluminum, iron alloy as the main metal electrode, with the aid of function produce electrochemical reaction with high frequency dc power supply, to convert electrical energy into chemical energy, at the expense of the anode metal electrode produce metal cation flocculating agent, through condensation, in addition, reduction and oxidation decomposition of pollutants from water separation, the technique of purifying water body.FunctionsElectrocoagulation has four main functions: Electrolytic oxidationElectrolytic reductionElectrolytic flocculationElectrolytic flotationThree auxiliary functions:Sterilization, Decolorization, Deodorization.  Main Feature• Low investment costs  • Low operating costs  • Low maintenance costs  • No need to add any chemicals  • Small footprint  • Simple operation, high degree of automation  • Short processing time and high processing efficiency  • Adapt to a wide range of wastewater, can treat a variety of pollutants  • Equipment treatment produces less sludge, high density of sludge  ApplicationElectrocoagulation can be widely used in many wastewater treatment industries. Such as electroplating wastewater, washing wastewater, and textile bleaching wastewater, paper mill wastewater, slaughter wastewater, waste water, food and beverage manufacturers oil refinery wastewater, oil field wastewater, pharmaceutical wastewater, mining wastewater, waste leachate wastewater, agricultural wastewater, paint dye, pigment, such as waste water, waste water cooling towers, wood processing waste water, the traveling scenic area sanitary sewage,  It can also be used for sewage purification at the bottom of the ship and port catchment area.  Detailed PhotosElectrochemical reaction: Fe→Fe2++2e.Anodizing reaction: 2OH-→2[O]+2e→02+2e, The nascent oxygen [O] has the same strong oxidation function as UV, H2O2 and O3.Cathode reduction: 2H++2e→2[H]→H2, nascent hydrogen can break bonds, COD, chromophore functional groups and multi-chain health.The above oxidation and reduction functions occur continuously on the plates.Technical advantages1. Compared with filtration, membrane separation, UV disinfection process, the application of a wide range of high processing efficiency, processing diverse objects.2. 96% of the ozone utilization rate, saving the cost of ozone equipment for disinfection.3. Removal of organic matter, phosphide, kill pathogens, bleaching and other treatment effect is good.4. Particularly suitable for the treatment of wastewater containing difficult to decompose substances.    Differences between Electrocoagulation and Traditional processProcessAir flotationFlocculationOxidationReductionMain FunctionOil RemovalDecolorizingSS RemovalPretreatmentDecolorizingSS RemovalPretreatmentPretreatmentDeep treatmentBreak complex formingPretreatmentTraditional ProcessOrdinary air flotationThe bubble is larger, and the removal effect of tiny oil particles and suspended matter is poor, so it needs to add agents, and the organic pigment can hardly be removed  Dosing flocculationDosage needs to be adjusted according to the different water quality, the sludge production is large, the drug cost is high, the treatment effect is unstable, almost can not remove organic pigment   Oxidant oxidationLow oxidation rate, dosage changes with water quality, not easy to adjust, high pharmaceutical costs   Reduction with reducing agentThe reduction rate is low, the dosage changes with the water quality, it is not easy to adjust, and the drug cost is high  ElectrochemistryThe bubbles produced are tiny and can remove pollutants from tiny particles without the need to add additional agents. There is no need to add flocculant, and the change of water quality has little influence on the treatment effect.  The treatment effect is stable and the sludge production is small.Without adding oxidant, the oxidation efficiency is high, the breaking of the colla
