Product DescriptionDescriptionElectrocoagulation(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.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.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, car washing
wastewater, textile bleaching wastewater, paper mill wastewater,
slaughtering wastewater, food and beverage factory
wastewater,oil refinery wastewater, oil field wastewater,
pharmaceutical wastewater, mining wastewater, waste leachate
sewage, agricultural wastewater, painting and dying
wastewater, pigment wastewater,sewage cooling
towers wastewater, wood processing wastewater,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 PhotosElectrocoagulation Dissolved Air
Flotation (EC-DAF) machine 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. FunctionsElectrocoagulation has four main
functions: Electrolytic oxidationElectrolytic reductionElectrolytic
flocculationElectrolytic flotationThree auxiliary
functions:Sterilization, Decolorization, Deodorization.
Electrochemical 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

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 collateral is more than
99%, and the effluent B
