Fracking, or hydraulic fracturing, is a widely employed technique in the extraction of natural gas. This process involves injecting a high-pressure mixture of water, sand, and chemicals deep into underground shale rock formations to create fractures. These fractures allow the trapped natural gas to be released and extracted efficiently. While the method itself is not new—it has been in use for over 60 years and applied to more than one million wells—it continues to generate debate due to its environmental impact, particularly concerning water usage and wastewater management.
Hydraulic fracturing operations require substantial amounts of water. A single fracking well typically consumes millions of gallons of water, with the composition of the fracturing fluid being approximately 98.0-99.5 percent water and sand. The remaining fraction consists of chemical additives, which vary based on the characteristics of both the water used and the specific shale formation being fractured. Once injected, a portion of this fluid—ranging from 20 to 40 percent—returns to the surface as flowback water. This water is often contaminated with not only the original chemical additives but also naturally occurring substances from deep underground, including heavy metals, salts, and hydrocarbons.
The disposal and treatment of fracking wastewater pose significant environmental challenges. Proper management of this wastewater is essential to prevent contamination of groundwater and surface water sources. One effective solution for addressing oil contamination in fracking wastewater is the use of oil skimming technology. Oil skimmers take advantage of the differences in specific gravity and surface tension between oil and water, allowing them to efficiently remove floating hydrocarbons from the wastewater before disposal or further treatment.
Belt Oil Skimmers: Efficient and Eco-Friendly Wastewater Treatment
Belt oil skimmers, in particular, offer an environmentally responsible and cost-effective method for removing trace amounts of oil from fracking wastewater. These skimmers operate by continuously attracting oil to a moving belt, which then scrapes off the contaminants and collects them in a designated container. With the ability to function in depths of up to 100 feet and operate 24/7 with minimal supervision, belt oil skimmers provide a low-maintenance and energy-efficient solution for wastewater treatment facilities.
Beyond fracking applications, oil skimming technology is widely used across various industries. Companies rely on oil skimmers for industrial wastewater treatment, groundwater remediation, and coolant management in machine shops. By effectively removing oil from these fluids, skimmers help businesses comply with municipal and Environmental Protection Agency (EPA) water quality regulations while also extending the lifespan of machine tool coolants. Additionally, oil skimming serves as a valuable pre-treatment step before filtration, preventing oil from clogging or reducing the efficiency of filter media.
As concerns over water contamination and environmental sustainability continue to grow, the role of advanced wastewater treatment solutions, including oil skimmers, becomes increasingly critical. Implementing such technologies ensures that industries utilizing hydraulic fracturing and other water-intensive processes can mitigate their ecological footprint while maintaining compliance with regulatory standards.
