Platinum and mmo-coated titanium anodes and titanium electrodes for electroflocculation
The working principle of electronic flocculation system:
Sewage undergoes unique electro-chemical processes as it passes
through an electro-flocculation system, including:
- Charge condensation:
When the plate is energized, an electric charge will be generated,
and the electric charge will attract the surrounding small
particles, break the original stable state of the material, and
change the polarity of the particles to make the small particles
bond with each other to form new large particles, which are easy to
precipitate.
-Demulsification:
The current splits H2O into hydroxide ions. These hydroxide ions
combine with hydroxide ions in dissolved emulsified oil, sludge,
dyes and other molecules to form water molecules, and at the same
time replace oil, sludge, dyes, etc. to form insoluble substances,
and precipitate.
- Formation of halogen complexes:
When the plate is energized, metal ions are generated at the same
time. These metal ions combine with chloride ions in chlorinated
hydrocarbons in sewage to form complexes that are easily
precipitated. Contaminants removed include pesticides, herbicides,
chlorinated PCBs, and more.
-Bleach:
Oxygen ions generated around the plates also have a bleaching
effect.
- Electron flooding:
The large flow of electrons present in the water eliminates the
polarity of the hydrate, freeing and precipitation of colloidal
substances, and at the same time, the increase in the amount of
charge will form an osmotic pressure and thus kill bacteria, cyst
viruses, and the like.
Advantages of electronic flocculation technology:
Cost savings: including initial and running costs
Manpower saving: basically no maintenance
It will not cause secondary pollution of water quality and
sediment: the usual chemical dosing method will change the PH value
of water quality and produce new chemical products that pollute the
environment
Improve the recycling rate of industrial sewage: more than 95% of
the sewage treated by the electronic flocculation system can be
reused.
Disinfecting sewage: Electro-flocculation technology can kill
bacteria and viruses in sewage at the same time
Prevent scaling: Electro-flocculation technology removes calcium
ions from water
Method description:
This is a process of breaking the stable state of suspended,
floating or dissolved pollutants in the water by passing an
electric current through the water, and the electric energy passed
into the water will drive the chemical reaction between the
substances. When the chemical reaction is driven or forced to
start, various components and compounds will tend to find a stable
state under the action of electric current. Often, the result of
this approach to a steady state is the formation of a solid-like
substance: this solid-like substance will exist in a non-colloidal
or non-dissolved state and thus be easily removed by subsequent
separation techniques.
In the process of electronic flocculation, electric current is
introduced into the water to be treated through plates made of
different metal materials. The selection of metal materials is
related to the types of pollutants contained in the water to be
treated to meet the effect of maximizing the removal of pollutants.
According to Faraday's law, the metal ions on the electrode will be
separated or replaced into the liquid medium. After these metal
ions form metal oxides, they will be attracted and combined by
various pollutants that have broken the stable state to form the
above-mentioned solids that are easy to be separated and
precipitated. like substance.
Applicable fields:
1. High turbidity and high suspended solids sewage treatment:
coal-containing wastewater from thermal power plants and coal
plants, high suspended solids sewage from ceramics and building
materials industries, ore washing sewage, and comprehensive
recycling treatment of papermaking white water
2. Treatment of oily wastewater: wastewater in the process of oil
extraction, condensed water in petroleum coking furnaces, oily
wastewater in metallurgy and mechanical processing industries
Precious Metal Coated Titanium Electrode Titanium Anode:
Coated titanium electrode refers to pure titanium as the base,
which can be in the form of titanium plate, titanium mesh, etc.
After special treatment on the surface of the titanium base, metal
or metal oxide, preferably noble metal or noble metal oxide is
coated on the surface. The surface of the titanium substrate is
combined into a whole, so that the corrosion resistance of the
titanium substrate and the conductivity and catalytic activity of
the noble metal oxide attached to the surface are organically
combined, so that the titanium electrode has excellent performance.
Advantages of Coated Titanium Electrodes:
1. The anode size is stable, and the distance between electrodes
does not change during the electrolysis process, which can ensure
that the electrolysis operation is carried out under the condition
of stable cell voltage.
2. Low working voltage, low power consumption, DC power consumption
can be reduced by 10-20%.
3. Titanium anode has long working life and strong corrosion
resistance.
4. It can overcome the dissolution problem of graphite anode and
lead anode and avoid contamination of electrolyte and cathode
products.
5. High current density, small overpotential, and high catalytic
activity of the electrode, which can effectively capture high
production efficiency.
6. In the production of chlor-alkali, titanium anode is used, which
has high product quality, high chlorine gas purity, no Co2, and
high alkali concentration, which can save heating steam and energy
consumption.
7. It can avoid the short circuit problem after the deformation of
the lead anode and improve the current efficiency.
8. The shape is easy to make and high precision is possible.
9. The titanium base is reusable.
10. Low overpotential characteristics, the bubbles on the surface
between electrodes and the electrodes are easily removed, which can
effectively reduce the battery voltage of the electrolytic cell.
