The old adage that oil and water don’t mix is somewhat true, but when it comes to fracking, oil and water can – and do – mix, and it can cause environmental pollution and other problems to living beings.
HYDRASEP has developed a system to separate oil and other immiscible liquids from water. This system is based on Stoke’s law, a principle of physics, which has to do with how irregular shapes, like oily liquids, move through fluids like water.
When any solid or liquid object moves through a fluid, it creates drag. Specifically, viscous drag. As this substance falls through the liquid, it creates velocity (the equivalent speed and direction of motion). As the substance’s velocity increases, it will eventually reach its terminal velocity, which is when the drag is balanced by gravitational force exerted upon it and its constant velocity.
Got all that? No worry. The long and short of it is once oil is in water, it’s really hard to separate if there is no motion imposed upon it. That’s where the HYDRASEP system comes in, which is specifically designed to move oily substances and make them cluster together so they can be removed all at once.
HYDRASEP’s bubble spin principle provides motion to water so solid objects will settle and can be accumulated. The second phase of the bubble spin principle is to keep the oil and water from remixing. Once the water has been treated, it can be discharged, recycled or transferred on for other treatment or uses.
