EXPERIENCE THE Big D Difference

Water Treatment


BIG D NOW OFFERS THE MOST INNOVATIVE, CHEMICAL DRIVEN PROCESS FOR THE TREATMENT OF FLOWBACK AND PRODUCED WATER FOR THE OIL AND GAS INDUSTRY

With our recent acquisition of both straightforward and fully automated NAP Water Treatment systems, we are now able to offer our clients a low cost, high volume option for treating up to 50,000 BPD. These mobile units feature a minimal footprint and can treat produced or flowback water as well as treating water “on the fly” for frac jobs.

Our patented mobile water treatment systems are designed to allow you to economically remediate your highly toxic flowback and salty produced water and bring them to a quality standard that ranges from simple reuse all the way to surface discharge.

With our range of environmentally-friendly chemicals, the oil and gas industry can now operate drilling rigs safer, cleaner and more cost effectively.



INFLUENT/EFFLUENT COMPARISON

Units Influent Effluent Efficiency
Total Suspended Solids mg/l 2,390 44.9 98.1%
Oil and Grease mg/l 27,000 <5.49 99.9%
Turbidity NTU 266 1.77

TYPICAL USES:

Reinjection for disposal

Injection of clean brine protects the integrity of the injection wells
Estimated oil recovery ranging from 2-7%
Lower overall operating costs

Fracking operations

Clean brine may reduce the use of fresh water during fracking operations

Lower operating costs for fresh water, transportation, disposal, etc.

Less environmental impact

Reinjection for waterflooding

Injection of clean brine protects the integrity of the formation

Alternative for traditional oil/water separation facilities

Capable of handling oil concentration up to 25% oil to water

WITHIN THIS ROBUST PROCESS, NAP TECHNOLOGY

Removes total suspended solids, metals and heavy metals
Oxidizes iron
Oxidizes hydrogen sulfide
Breaks down residual polymers
Kills bacteria
Destabilized dissolved organics

How does this work?

Step 1: Chemical Injection

NAP uses only non-hazardous, non-DOT regulated chemicals in all operations
The equipment allows the use of up to six different chemicals in the process, depending on the properties of the water to be treated

Step 2: Dissolved Air Flotation

Acceleration of oil/water by injecting microscopic air bubbles to the water
Skim separated oil from the water surface
Allows 99% and up recovery of free and emulsified oil in water
Polypropylene design of the unit provides resistance against corrosion
Separated oil is skimmed off of the surface of the DAF tank
Water is then drawn from the middle of the tank to a separate compartment within the DAF

Step 3: Water Filtration

Submicron multimedia filter
Effluent water turbidity below 5 NTU (comparable to drinking water)

Results

Total solids removal 98% and up
Oil and grease removal 99.9%
Turbidity below 5 NTU
No presence of H2S in the influent/effluent sample
Oil recovery 99% and up
