Unique Electrocoagulation Equipment: YASA ET PREDEST

electrocoagulation equipment yasa et predest

Electrocoagulation, the passing of the electrical current through water, has proven very effective in the removal of contaminants from wastewater.

The electrical current provides the electromotive force causing the chemical reactions. Sacrificial electrodes supply either aluminium or iron cations that assist in a formation of more stable compounds – the contaminants form precipitating hydrophobic entities.

Electrocoagulation systems have been in existence for many years and a variety of anode and cathode geometries, such as plates, balls, fluidized bed spheres, wire mesh, rods, and tubes can be used to achieve the desired results.

YASA ET is proud to introduce our patented technology of PREDEST® electrocoagulation equipment, which was proven successful in treating many kinds of wastewaters.

YASA ET PREDEST® wastewater treatment allows several distinct electrochemical processes to occur during the electrocoagulation process. These observed reactions might be explained as:

  • Seeding - anode reduction of metals ions that become new centres for larger, stable, insoluble complexes, precipitating as complex metal oxides;

  • Emulsion breaking - forming water soluble complexes and that way separating oil, drillers mud, dyes, inks, from the wastewater;

  • Halogen complexing - as the metal ions bind themselves to chlorine and form chlorinated hydrocarbon molecules – resulting in the formation of large insoluble complexes and isolating pesticides, herbicides, chlorinated PCBs, etc.;

  • Oxidation and reduction reactions - electrocoagulation can speed up the naturally occurring processes.

YASA ET PREDEST® is the most cost effective and elegant solution for many water treatment problems. The advantages of our electrocoagulation equipment are:

1) The system have a small footprint;

2) It requires minimal additional chemicals to achieve the desired results;

3) It uses a lower amount of power compared to other systems.

PREDEST® electrocoagulation technology handles mixed waste streams (for example water polluted with oil, metals, and bacteria) very effectively as different processes take place at the same time and wastewater characteristics (pH, standard redox potential, conductivity) can be varied and optimized for maximum removal efficiencies of specific material treated.

After the treated wastewater leaves the electrocoagulation chamber, the destabilized colloids are allowed to flocculate in the settling tank and then separated in an integrated system. Membranes can also be integrated in PREDEST® to achieve the desired treatment results.

If required, the sludge from PREDEST® after the electrocoagulation can be further de-watered using a filter press, settling pond, or other de-watering techniques.

Finally, the electrocoagulation solution offered by YASA ET with its PREDEST® can be applied for the treatment of many different wastewaters and it represents a very cost-effective solution.
