The customer has spoken.

Offshore produced water treatment needs a simple continuous treatment solution that minimizes filter media. Water To Sea listened.

The Water To Sea system combines  proven and patented treatment technologies for global offshore produced water, flowback water and slop water.

The temporary service package is built to a global offshore industry standard and tailored to meet national standards.

The heart of the system is an innovative Electrochemical Process coupled with separation and automated monitoring technology.

The result is an automated package with a compact footprint and lighter weight, which treats at a higher flow rate and requires less manpower than current offshore alternatives. All leading to better value and improved economics for our customers. 

A perfectly adaptable closed system, designed for constantly changing fluids conditions without sacrificing performance. 

Here’s how the patented process works:

The produced water will flow through our customer interface skid which can be safely adapted for changing pressures and flowrates.

Then into our patented, pressurized Thincell technology, which cleans produced water with a combination of electrolytic oxidation, emulsion destabilization, electrocoagulation and flocculation.

Flocs are then separated using our patented ThinSep technology and removed within minutes, faster than ever achieved before.

After ThinSep separation, the water is polished using our patented ThinFloc technology.

Results are monitored, then water is released overboard, meeting global environmental discharge standards.

Water To Sea’s treatment solution includes a mobile power distribution system which allows for a single tie-in and can be easily located close to the customer’s motor control center for simple power termination.

Water To Sea’s Thincell technology utilizes five distinct and patented processes; a completely pressurized vessel, a unique electrical transfer system, a non-passivating and non-corroding anode and cathode that require no cleaning due to proprietary design and coating, a completely bipolar sacrificial multivalent electrode and a unique treatment cell that incorporates a fluidized bed with optimum current density. Thincell creates minimal waste, a claim no other temporary treatment technology or service company can make.

Thincell’s unique design results in low energy needs, minimum maintenance costs, reduced HS&E risks, smaller footprint, much lighter equipment design and continuous high-volume treatment rates.

Compare Thincell to traditional Electrocoagulation, a method that uses hundreds of metal plates or discs as the electrodes.

The “dirty little secret” is that almost immediately, the metal plates begin to corrode and scale, or passivate.

Efficiency through the process drops, requiring more power while the capacity to process fluids continues to decrease.

After efficiency decreases enough or maximum power has been reached, the system needs to stop.  The plates must be lifted out, replaced with new plates. (pause) To reuse them, they must be acid washed or disposed of completely no matter the configuration.

The size and weight of the equipment, excessive downtime, reduced treatment rates, costs and, most importantly, risk to persons on board have been the primary challenges to using traditional Electrocoagulation in most applications.

In the Water To Sea system, only one worker is needed to replace the consumed metal electrodes, replenishing each reaction chamber to keep the system running.

Quite a difference.

Now, let’s compare the Thincell process to the global benchmark, which utilizes filtration media.

The amount of media required is determined by flow-rate and inlet water quality and can include hundreds of individual canisters or tens of thousands of pounds of bulk media. 

The filtration media spends quickly and has limited life at high-treatment rates and at elevated concentrations of contaminants such as solids, oils and emulsified fluids. 

Media replacement requires frequent shutdowns, taking roughly twice as long at twice the cost. And there’s the long-term responsibility for all the waste filters and bulk media disposaL  

Even newer options being introduced into the market as consumable- and chemical-free, such as membranes, are not.

Membranes are an expensive consumable and are extremely susceptible to irreversible fouling, which leads to extended downtime due to frequent replacement. The treatment rates are low because 50-80% of the inlet flow goes to the reject line forreprocessing before compliant discharge or disposal.  Minor increases in treatment rate require a significant increase to the footprint.

Imagine the deck of a fixed or floating production platoform. The footprint and weight of the package is a big consideration for the customer.

Even cranes have limitations on weight they can lift.

This is a representative footprint of the current global benchmark for temporary produced water treatment that can treat up to 7,500 barrels per day.

This is the Water To Sea package that can treat up to 12,000 barrels per day.

With its automated components, also consider that the personnel needed to run the Water To Sea unit is less than the filtration package.
