Hydrofracking drives new water treatment solutions
A surge of toxic hydrofracking wastewater has given rise to new
chemical free treatment technologies with the potential to solve other
nagging environmental challenges ranging from coal mines and pig farms.
I recently spoke with Charles Vinick, CEO of Ecosphere Technologies,
to learn about its ability to reduce oil and gas mining operations’
dependence on chemicals that are potentially harmful to people and
wildlife. Wells throughout the United States are injected with biocides,
friction reducers, and scale inhibitors to protect equipment, but
ultimately create a toxic brew of wastewater.
Ecosphere utilizes a proprietary oxidation process called “Ozonix” to
treat industrial wastewater. Its energy subsidiary has built mobile
treatment facilities with that can currently handle 5,000 gallons per
minute. Water is “recycled” and can be reused in other wells,
eliminating the need for an injection well to keep pollutants out of groundwater, said Vinick.
The technology has been approved by the Oklahoma Corporation
Commission for soil farming, and third party laboratory tests has
demonstrated a drastic reduction in microbes - from high to undetectable
- after just one past, Vinick says.
Treating the water also eliminates the need for the aforementioned
chemicals, but some mining operations will continue to use chemicals
nonetheless to reduce risking their investment, Vinick added. “It is a
cost effective alternative to chemicals. [Mines] wouldn’t use it if it
added costs.”
Ozonix treated over 1 billion gallons of wastewater in 2011 at over
500 onshore oil and gas wells. Ecosphere’s oil and gas revenues have
increased 10X over the past two years. Other companies, including OriginOil, offer competing solutions. “Because
states are persuading themselves to let fracking go on, they will
create a booming market for cleanup,” said Riggs Eckelberry, CEO of OriginOil.
However, water pollution is not limited to oil and gas. Ecosphere is
in discussions to license its technology to companies that treat
coalmining waste and pig farms located within the Chesapeake Bay
watershed. It currently partners with Hydrozonix in the United States.
Vinick, who spent 25 years as managing director of the Cousteau
group, believes that companies like Ecosphere are solution providers
that will help solve the world’s environmental problems.
“I think that you need activists and solution providers,” he said.

Safer fracking may be possible. Biofuel start-up OriginOil has devised a new
process to treat water that’s been tainted by gas and oil drilling, reducing
production costs and limiting environment harm.
A noxious brew of chemicals, mineral, or petroleum, mixes with drilling water
whenever oil and gas companies use a drilling technique called hydraulic
fracturing, or “hydro-fracking.” This waste is typically pumped out and trucked
off to disposal wells for storage, or is eventually treated.
The industry’s term for the brew is “flowback water”, and it’s aptly named.
Handling it harms the bottom line of energy companies as well as the
environment. Transporting flowback water adds US$2-5 cost per barrel of oil,
said Riggs Eckelberry, CEO of OriginOil. “There’s nothing pretty about
that.”
“Permits for disposal wells not being granted anymore,” Eckelberry added.
Energy companies are “looking for a fig leaf” as public scrutiny increases, he
said. “The fact is we really do help. They need the petro fully recovered and
water cleaned.”
Recent Environmental Protection Agency studies found that hydro-fracking
tainted an aquifer in Wyoming.

OriginOil is applying its algae harvesting process to the problem.
Third party PACE Engineering showed that the technology was able to
remove 98% of hydrocarbons from a sample of West Texas oil well flowback
water in the first stage of its treatment, the company says.
Arm & Hammer didn’t invent baking soda to keep refrigerators
smelling fresh. It seized the business opportunity, and so to has
OriginOil by repurposing its intellectual property. The process uses
less energy than traditional treatment methods and is chemical free. Oil
service companies would license the technology, paying royalties to
OriginOil.
Three proof of concepts for oil drilling applications are planned to
begin within the next several weeks, and Eckelberry expects that the
technology will be proven by the end of this summer. Cleaning up natural
gas fracking operations will happen further into the future, he noted.
“I totally think we can help with gas fracking; we just haven’t
tested it yet,” Eckelberry said.
The process can remove undesirable
organics such as arsenic and polymers that are using to extract gas, he
explained. ”The perception is that natural gas is upsetting biofuels. It
helps for us to have role in fracking, which grew 64% from 2010-2011.
This will only make algae interest stronger.”
