Municipalities of all sizes are faced with increased pressures to provide clean water in volumes necessary to accommodate their growing populations. For the better part of a century, Electrocoagulation (EC) has proven to be the technology of choice for the removal of suspended solids in municipal wastewater treatment facilities without the need of chemical additives. It has been effective in treating sewage water and sludge.
Traditional EC technology provides numerous benefits to municipal treatment facilities with its ability to:

  • Break emulsions
  • Destabilize colloidal particles
  • Remove a broad range suspended solids
  • Assist in the destruction of bacteria and pathogens
  • Meet discharge requirements in a single treatment.

This breakthrough technology targets the removal of more than 35 different contaminants from periodic table elements, including silica and arsenic, while helping to lower water hardness in potable water. These elements are noted in light blue.

Electrocoagulation Technology – Elemental Contaminants Removed


Electrocoagulation (EC) works most effectively on the elements in the middle of the Periodic Table. Silica and arsenic are readily removed. In many waters hardness is also lowered.

Traditional EC, however, has a problem that has hampered its use. It has the susceptibility for anode and cathode passivation and scale buildup which can cause operating inefficiencies, premature systems shutdowns and high electrical usage.

Water Vision’s new Thincell® technology adds a new dimension to traditional EC treatment. Thincell provides a cost-effective, in-situ solution to contaminant removal without the problems connected with passivation.

HOW THINCELL WORKS TO TREAT MUNICIPAL WASTEWATER

Thincell’s Process – Stage 1-2

  • Suspended, stabilized and emulsified contaminants exist in fluid
  • Patented proprietary Anode and Cathode prevent electrode passivation
  • Suspended and stabilized contaminants are destabilized, and break into smaller particles.  Emulsified fluids are de-emulsified
  • Bi-polar “Sacrificial Electrodes” release metal ions to form in-situ coagulant

Thincell’s Process – Stage 3

  • Sacrificial electrodes completely dissolve and releases metal ions to form in-situ coagulant
  • Contaminant particles react with in-situ coagulant and form floc.
  • Hydrogen and oxygen bubbles formed at the proprietary cathode and anode carry floc to top of chamber for removal.

Thincell – “The Conductivity Bridge”

  • Patented non-passivating anodes and cathodes – 6” spacing
  • Bi-polar Sacrificial electrodes separated by water molecules form a “conductivity bridge”
  • Thincell treatment is efficient in low conductivity environment
  • Low conductivity treatment is not hindered by passivation.

Thincell’s many advantages make it the best solution for municipal wastewater processes.

What else can Thincell Handle?

Raw vs. Treated Sewage

As noted in the well-recognized Vanderbilt study results, removal of biological oxygen demand (BOD) and chemical oxygen demand (COD) in wastewater containment tests consistently exceed 95 percent.

Potable Water Results

Thincell causes a broad range of impurities to become separable from potable water.

Bacteria, Pathogen and Virus Removal

In a municipal wastewater facility, the Thincell electrocoagulation technology helps with bacteria, virus, and pathogen destruction as well as the removal of suspended solids in a single, efficient treatment. Its electrochemistry allows Thincell to be a natural in-situ disinfectant that upsets the ionic balance of the bacteria and removes dead bacteria through settling or flotation.

Thincell electrocoagulation cleans wastewater in municipal treatment facilities through a combination of electrolytic oxidation, emulsion destabilization, electrocoagulation, and flocculation in a single chamber. The technology easily adapts to existing plants without the need for costly retrofitting.

Thincell® EC Treatment 

Bacteria, Pathogens, and Virus Removal

Thincell’s unique electrochemical processes are extremely effective disinfectants. More importantly, the Thincell system disinfectants in one step where Traditional EC requires a second technology (electro-oxidation) to complete the disinfectant process.

Thincell electrochemistry produces an in-situ disinfectant that:

  • Upsets the ionic balance of the bacteria via electrocution
  • Generates sodium hypochlorite, hypochlorous acid, and ozone, known disinfectants.
  • Dead bacteria are removed via in-situ generated electro – coagulants through settling or flotation
