MIT Finds Way to Reuse Water from Fracking

fracking oil

Fracking, or the process of extracting oil from underground reservoirs, takes a lot of time, money, and water. But humans are extremely dependent on this technique because it brings out a natural resource that fuels transportation methods that we use in our everyday lives. Cars, buses, trains, and planes are just a few of the ways we get around that use oil as fuel. So how can a process that is so important still be so inefficient? Fracking wastes millions of gallons of water per year, water that could be reused for other purposes.

So why isn’t it being reused? Because when water is pressurized down into the ground to extract oil, it becomes contaminated and deemed “brimy”. This type of water is discarded into deep injection wells and new, clean water is bought to continue the fracking process.

Luckily a company that works with MIT has come up with a genius process to reuse some of these million gallons that are wasted every year. This company, called Gradient Corporation, has created a cost-effective process to treat brimy oilfield water for reuse. Depending on the location and type of fracking, carrier gas extraction (CGE) or selective chemical extraction (SCE) is used to clean the brimy water. Carrier gas extraction heats produced water into vapor and condenses it back into water without contaminants. In selective chemical extraction, chemical reactions remove specific contaminants. Both processes are effective, easy to use, and will save millions of dollars annually for fracking companies.

Reusing water is important, especially at a time when the West Coast is in a severe drought. It is important that every person does their part in helping to save water and save our environment. There are so many ways that you can save water, but one important way that also improves your health is to buy a water filtration system for your home that reuses backwash water. Think of it as your own system, like fracking, that can normally waste backwash water. Filtercon Technologies has developed a system that does just the opposite; reuses that water for other purposes while still purifying the water that goes into your home. Want to know more?
