Water Vision Inc is a Houston based company established in 2009 to provide clean water treatment solutions through the use of its innovative and patented ‘Thincell’ direct contact electrocoagulation technology. The company’s core business is the clarification and pathogen destruction of turbid wastewater, generated from multiple industrial operations including the Oil & Gas industry.
The company provides cost-effective high flow rate onsite water recycling solutions in a broad range of markets. In the Oil and Gas market the technology eliminates the need to truck flowback water to an offsite disposal facility, holding pond or recycling facility. In addition, the company’s technology kills bacteria at very high flow rates using its mobile and compact Thincell wastewater treatment units. Water Vision Inc is the only electrocoagulation company that can kill bacteria, and remove solids at the same time, with the same unit.
The Thincell units consume a readily available and cheap waste by-product during operation resulting in low operating costs while being environmentally beneficial. The use of a waste product as a consumable to generate clean water provides significant marketing and operating cost efficiencies over traditional electrocoagulation technologies.
Thincell technology utilizes the principals of electrocoagulation as its base process. Electrocoagulation is a water treatment technique, in which metal electrodes are dissolved electrochemically to induce coagulation of colloidal contaminants, eliminating the need for the addition of liquid Al+++ or Fe+++ coagulants, as required by conventional coagulation methods. While electrocoagulation is not new and is widely practiced, it has been limited to small scale operations due to design limitations. Electrocoagulation has not been applied in the Oil & Gas market segment in any significant way creating new opportunity for the technology in Frac, Flow Back and Produced Waters. Recent attempts to provide electrocoagulation services have been met with mixed results. All previous applications encounter the common problem of electrode fouling, when processing wastewater containing high dissolved solids and scaling compounds.
The problem of electrode fouling or passivation causes the electrocoagulation process to fail. Fouling on the electrode surface occurs within a few hours of processing resulting in reduced efficiency, increased power consumption, reduced bubble formation quantity and size and eventually resulting in a complete shutdown of the process. This typically requires disassembly of the electrode housing and manual cleaning. Air sparging and various acids have limited effect. Fouling results in a 20%-50% reduction in processing time, wear and tear on electrode cell assemblies, potentially dangerous leaks, personnel exposure, waste generation and the complete reliance on a manual inspection for electrode cleanliness.
WVI Thincell units have resolved these issues and produce a processing unit with no electrode fouling or passivation.
Coagulation is a critical physio-chemical operation used in water treatment. The process is used to cause the destabilization and subsequent aggregation of smaller particles into larger complexes. Water contaminants such as ions (heavy metals) and colloids (organic and inorganic) are primarily held in solution by electrical charges. Colloidal systems could be destabilized by the addition of ions of the charge opposite to that of the colloid. The destabilized colloids can then aggregate and subsequently be separated from the wastewater.
Electrocoagulation is a process of destabilizing suspended, emulsified or dissolved contaminants in an aqueous medium by introducing electrical current into the medium. The electrical current provides the electromotive force causing the chemical reactions.
Several distinct electrochemical processes occur during the electrocoagulation process independently. These include ; seeding resulting from the anode reduction of metal ions that become new centers for larger, stable, insoluble complexes, emulsion breaking resulting from oxygen and hydrogen ions reacting with emulsified substances and forming water insoluble material, halogen completing - as the metal ions bind themselves to halogens, bleaching by oxygen species produced in the reaction chamber and providing oxidation of chemical substances reducing bio-hazards through oxidation of bacteria and viruses and the electron flooding of the water affects the polarity of water, allowing colloidal materials to precipitate.
The electrons create osmotic pressure rupturing cell walls of bacteria, cysts, and viruses. Oxidation and reduction reactions are forced to their natural end point. Electrocoagulation can speed up the natural processes occurring in wet chemistry.
Water Vision’s patent pending Thincell System utilizing non-scaling sacrificial anode technology has numerous benefits over traditional systems:
- Reduce suspended solids, colloids and emulsions.
- Requires no chemicals
- Generates Cl2, ozone, peroxide and HOCl which are all strong oxidants which destroy the cells of bacteria resulting in high bacteria and pathogen kill.
- Reaction occurs in seconds requiring a small contact vessel and residence time, thereby lowering the overall foot print.
- According to US EPA, “When compared with alum (aluminum sulphate) treatment, electrocoagulation provided approximately 83% less sludge volume and a 76% improvement in filtration rate.”
- Can provide a complete pre-treatment solution to desalination technologies.
- Design allows for constant electrocoagulant production without the typical loss in efficiency due to passivation/scaling of the anode.
- The WVI sacrificial anode is inexpensive and non-scaling. This eliminates the need for chemical cleaning or grinding and removes the risk of chemical exposure.
- Proprietary sacrificial anode allows for higher current densities without concern for scaling which can result in the production of higher concentration of oxidants.
