Electro coagulation Plants

Process Principles: Electro coagulation

Electro coagulation is a water treatment process whereby an electric current is applied across metal plates to remove various contaminants from water. Heavy metals (ions) and colloids (organics and inorganics) are primarily held in solution by electrical charges and particle size. By applying an electrical charge to a solution of contaminated water, you can destabilize the charges on the various particles and generate a coagulation reaction.

L.D Engineering has been designing, manufacturing, and deploying high-flow, packaged electro coagulation systems .From the start, our primary goal as a company was to build the best electro coagulation system in the world. After many years of research and development, we built our first full-scale system. we put our technology to work in full-scale operation at some of the dirtiest, most challenging sites


  • All systems are pre-engineered and can be delivered packaged, weatherized.
  • Non-selective treatment is broadly effective and largely independent of contaminant species, concentrations, and competing properties
  • Extensive automation controls and alert systems significantly reduce operational maintenance and labor
  • All systems are intrinsically safe
  • Subtractive process does not require any chemical reagents or polymers; typically produces 26-60% less sludge than conventional chemical processes

Treatment Targets

  • Total Suspended Solids, Turbidity
  • Heavy Metals (Cu, Zn, Pb, As, Cr, Fe)
  • Oil & Grease (TPH, PAH, cPAH, Emulsified Oils)
  • Bacteria (Total Coliforms, E. Coli)
