The Water To Sea Thincell® unique electrochemical technology comprises multiple distinct and patented processes within its completely pressurized fluidized treatment vessel. These result in a multitude of treatment reactions in one vessel including electrolytic oxidation, emulsion destabilization, electrocoagulation, flocculation, and the formation of a flotation catalyst.

Thincell’s main features are proprietary coated anodes and cathodes that are non-passivating and non-corroding, eliminating detrimental scale buildup.  Within fluidized treatment cells, sacrificial bi-polar multivalent sacrificial electrodes release metal ions forming an in-situ coagulant. Contaminants react with the coagulant forming floc that is further flocculated, floated, and separated.   

The result is highly-effective contaminant removal within a small footprint that minimizes operating and maintenance expenses, and lowers personnel safety and environmental risks, all while producing higher continuous treatment rates than any alternative.

THINCELL – Outperforms Bulk, Cartridge and Membrane Filtration

Filtration has been the industry benchmark for temporary offshore water treatment.  Depending on the flow rates and desired water quality, this alternative can include significant numbers of sock filters, individual wound filtration canisters, tons of bulk filtration material, or significant quantities of membrane filters.  

Filtration media life is reduced with high treatment rates, and excessive contaminant levels significantly diminish its useful life. Newer membrane filter technology is extremely sensitive to fouling which significantly lowers flow rates, increases reject rates and necessitates reprocessing in order to achieve compliant discharge.  Membrane media backwash, chemical cleaning or replacement can cause significant downtime and extra maintenance costs. Disposal of filters, spent bulk media, membranes, and membrane chemical cleaning and backwash residual is not only an environmental liability and expense, but frequently requires the use of standby service vessels and additional onshore dock time, which drives costs even higher.
