AQUA-VES MOBILE WATER-TREATMENT SYSTEM
THE PORTABLE AND UNEQUALED SOLUTION FOR ALL YOUR WATER MANAGEMENT NEEDS
Ask any operator in the unconventional shale plays to identify one of their primary issues and more times than not the answer will center on water. With freshwater supplies often limited, public and regulatory scrutiny increasing and disposal options few and far between, shale operators face ever-mounting environmental and economic pressures.
The NOV FluidControl newly engineered AQUA-VES mobile water treatment system takes some of the pressure off with a technically advanced, on-location solution for treating and reusing precious water resources. AQUA-VES employs patented membrane separation technology to give operators a cost-effective option for managing frac flowback, slop water and produced water.
The trailer-mounted AQUA-VES water treatment system is designed to process up to 10,000 bbl/day of liquid waste in a small-footprint configuration. What’s more, since AQUA-VES relies on vibration, the robust, Telfon-coated membranes remain much cleaner than standard filtration systems, continually keeping the path clear for unrestricted flow-through of proportionally larger fluid volumes. The capacity of AQUA-VES to remove the smallest entrained solids is reflected in its routine delivery of comparatively clean permeate with average Nephelometric Turbidity Units (NTU) levels below 5 and a near 100% reduction of oil and grease (insoluble organics) and bacteria levels, effectively allowing for recycling of frac flowback water and on-site disposal where permitted.

Good vibrations give AQUA-VES the edge
Most competitive water treatment systems employ crossflow filtration that requires excessively high flow rates to keep the filters clean. Not only does this methodology need more energy to function, it filters a comparatively smaller percentage of the total flow.
Since the membrane itself vibrates, fluid velocity at the wall is dictated by vibration rather than flow. As a result, the membrane remains clean, allowing for unobstructed filtration of a comparatively larger proportion of the flow through.
The flexible design of the AQUA-VES mobile watertreatment system accommodates the installation of a wide range of membrane sizes, from micro filtration to reverse osmosis, making it well-suited for a wide range of operating environments.
As an added bonus, since AQUA-VES employs surface rather than depth filtration, when membrane cleaning is required it can be accomplished on the surface without the downtime associated with disassembling and cleaning a soiled depth filtration unit. And, as the hardy membrane coating is tolerant to acids, solvents and nearly every other cleaning compound imaginable, there are no restrictions on the cleaner used to extricate any fouling that may have occurred.
The advantages of vibratory filtration
Through the use of unique vibratory filtration technology, the NOV FluidControl AQUA-VES mobile water treatment system has a wealth of advantages over conventional filtration treatment systems:
- Minimal pretreatment: Owing to high shearing energy at the membrane surface and near the pores, colloidal fouling and concentration polarization are reduced considerably.
- Low fouling and scaling potential: Sinusoidal shear waves from the membrane surface help repel approaching particles and colloids, thereby reducing the potential for fouling and scaling.
- High permeate flux: AQUA-VES delivers throughput rates five to 15 times higher than conventional units. In addition, the shear waves propagating from the membrane surface hold suspended particles aloft, cleaning the way for free transport of the liquid through the membrane.
- Low energy consumption: High flux combined with minimal membrane scaling and fouling make AQUA VES an extremely energy efficient technology with on average usage of 0.27 kWh/kgal filtrate.
- Small footprint: As much as 2,000 sq ft of membrane is contained in one module with a footprint of 4×4 ft.
AQUA-VES engineered to be ready whenever, wherever you are
The easily transportable AQUA-VES technology comes to your location on a 53-ft trailer containing a pump skid and two membrane towers holding some 2,400 sq. feet of 0.05 um Teflon ultra-filtration membranes.
Should the scale of your operation require a strategically located, semifixed water treatment facility, the flexibility of the AQUA-VES design facilitates expansion to a larger unit. Once pilot testing confirms to your satisfaction that AQUA-VES, indeed, is the solution for your treatment management needs, we can readily scale a project-specific unit capable of processing as much as 10,000-bbl/day of liquid waste. What’s more, FluidControl is somewhat unique among treatment companies in that our water transfer services allow us to provide on-site delivery via pipeline.
At FluidControl, we are committed to reducing the costs and environmental liabilities of your unconventional shale operations and ensure optimal production does not come at the expense of often-strained local water resources. Nowhere is that commitment better reflected than in our AQUA-VES mobile water treatment system.
