The Water To Sea system combines multiple processes and modular components, working cohesively to achieve superior temporary offshore water treatment productivity.


CIS

 

Customer Interface System

Water To Sea’s interface system is the first step in our closed treatment process. It assures that safety is maintained and controlled regardless of pressure and flow rates.

Thincell®

Thincell®

The Thincell patented Electrochemical process system is equipped with two pressurized, fluidized bed reaction vessels. The dual design enables continuous flow with one-person maintenance and zero downtime.

Thincell’s proprietary anodes, cathodes and unique bi-polar multivalent sacrificial electrodes prevent passivation and corrosion.  The process has proven to be safe, cost effective, and flexible for continually changing waste streams.

ThinSep™

 

ThinSep™

The patent-pending Thinsep technology provides contaminant removal using a combination of coagulation, electro-chemically and mechanically-generated micro bubbles that flocculate, float, and separate contaminants from treated water.

ThinFloc™

 

ThinFloc™

The patent-pending ThinFloc technology reduces fine floc and suspended solid particulates, prior to discharge in accordance with environmental regulations or recycled for reuse.

PDS

 

Power Distribution System (PDS)

Using one cable, the Power Distribution System receives 440/480V 3-phase power from the customer’s motor control center and distributes it to the Thincell electrochemical process system and the recirculating pumps. The Power Distribution system also transforms the power to 120 volt single-phase for use with the treatment system automation, instrumentation, and control.



PS

 

The Pump System

Redundant electrically-driven centrifugal pumps provide fluid return, recycle and, if needed overboard discharge capabilities.  The pumps utilize variable frequency drives (VFD) for site specific operation.



TOG

 

On - Line Oil and Grease (TOG) Analyzer

Treated water is analyzed before discharge and can be automatically diverted if reprocessing is necessary.



+ THINCELL – How it Compares to Traditional Electrocoagulation

Tradional electrocoagualation has been utilized as a temporary offshore treatment process for intervention flow back fluids, off-spec produced water, and slop waters. Traditional electrocoagulation methods employ hundreds of metal plates or discs as electrodes (anodes and cathodes), resulting in a large and heavy footprint. Plate life is minimized by rapid corrosion and passivated scaling. Once these detrimental conditions arise, critical process efficiency drops, energy requirements rise, and the system shuts down. The plates must then be physically removed and either acid washed or disposed of. This process quickly becomes power inefficient, labor intensive, high risk, costly, and ineffective, resulting in water quality environmentally unsuitable for overboard discharge or injection.

+ THINCELL – How it Compares to Filtration

Filtration, which utilizes consumable, disposable filtration media has been the industry benchmark for temporary offshore treatment of intervention flow back fluids, off-spec produced water, and slop waters. Depending on the flow rates and water quality, this alternative can include significant numbers of individual sock filters, wound canisters or tons of bulk filtration material.

As with electrocoagulation, the media life is reduced with high treatment rates and excessive contaminant levels. Media replacement results in significant downtime and consumable costs. Disposal of filters and spent bulk media is an additional expense and frequently requires the use of standby service vessels, signicantly increasing overall project costs.

+ THINCELL – How it Compares to Membrane Technology

Membrane filtration technology has recently been introduced into the temporary water treatment service market, as a low cost no filtration media alternative. Membrane filtration is not the answer that has been promoted. Even with robust contaminant pre-treatment, this alternative is susceptible to membrane fouling, leading to frequent downtime for backwash, chemical cleaning, or in the case of irreversible fouling, expensive replacement. Treatment rates are typically 50-90% of the inlet flow, generating a massive reject stream which necessitates water reprocess to achieve discharge suitability.
