QDEVU Electrocoagulation(EC) Plant
Description
Electrocoagulation(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) 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.
Working Principle
Electrocoagulation 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.
Functions
Electrocoagulation has four main functions: Electrolytic oxidation
Electrolytic reduction
Electrolytic flocculation
Electrolytic flotation
Three 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
Application
Electrocoagulation 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.

| Traditional Process |
Ordinary air flotation
The 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 flocculation
Dosage 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 oxidation
Low oxidation rate, dosage changes with water quality, not easy to adjust, high pharmaceutical costs |
Reduction with reducing agent The reduction rate is low, the dosage changes with the water quality, it is not easy to adjust, and the drug cost is high |
| Electrochemistry | The 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/C is more than 0.35 stable. |
The reduction rate is above 99.5% without adding reducing agent |
| Application | Floating oil waste water The desulfurization wastewater Papermaking wastewater Coal chemical wastewater Petrochemical wastewater |
Printing and dyeing wastewater Pharmaceutical wastewater |
RO concentrated water treatment Coke copper wastewater Electroless nickel plating wastewater Wastewater containing complex compounds High concentration wastewater |
Chromium plating wastewater |
