KFM Activated Media Filter: Innovative Solution for Oilfield Wastewater Treatment
Introduction
With the advancement of oilfield exploitation, particularly as it enters the mid-to-high water-cut stage, the treatment of polymer-containing wastewater has become an urgent issue to address. Due to the presence of polymers, this type of wastewater exhibits complex water quality, high viscosity, and high proportion of emulsified oil, posing significant challenges to traditional filters. In response to this problem, the KFM Activated Media Filter has emerged as a viable solution, demonstrating significant application potential in oilfield wastewater treatment due to its unique advantages.
The KFM is a highly efficient filtration device that adopts a novel type of activated filter media. This novel activated media is a reactive substance made from silicic material, manufactured through 60 processes and treated with super-hydrophilic modification technology. It features a high melting point, moderate specific gravity, odorlessness, and insolubility in water. More importantly, its surface inherently has electric charges, enabling it to adsorb pollutants and possess bactericidal capability. These characteristics enable the KFM activated media filter to effectively remove colloids, suspended solids, microorganisms, and other impurities from water during the filtration process, while ensuring consistent effluent quality.
KFM Activated Media Filter
The Dual-Mechanism Filtration Process
In the process of wastewater treatment, the filtration functions of the KFM activated media filter lie in two aspects: 1. The migration of particles in the water moves toward the surface of the filter media. 2. The adsorption of these particles onto the filter media's surface. This process occurs within the voids of the filter media. The larger the surface area of the filter media, the better the interception efficiency. The activated surface area of the KFM activated media filter is up to 3000 times greater than that of quartz sand, resulting in significantly superior interception performance. As suspended particles continuously accumulate in the voids of the filter media, the resistance from deposited particles increases. When this resistance equals the adhesive force, particles are released and migrate to the surface of deeper filter media layers, thereby further enhancing the filtration efficiency.
Treatment Performance of Oilfield Produced Water
Distinct Advantages Over Traditional Filters
The KFM activated media filter has exceptional performance in the application of oilfield wastewater treatment. When traditional filters handle polymer-containing wastewater, many problems might occur. For example, the filtration material is easily polluted, the treatment performance is poor, and the back-flushing is difficult. In contrast, the KFM activated media filter successfully overcomes these issues with its high filtration accuracy, low resistance, stable effluent quality, strong anti-fouling capacity, easy cleaning, and long service life. Practical applications have proven that the KFM filter significantly reduces oil content and suspended solids in the effluent while ensuring compliance with relevant water quality standards.
In addition, the KFM activated media filter also features small footprint, low construction cost, and other advantages. The skid-mounted design makes the equipment more flexible for various scenarios, significantly improving the wastewater treatment efficiency. Moreover, the system eliminates the need for high-head, high-flow backwash pumps during operation and can utilize intermittent sand washing, further reducing operational expenses.
Conclusion and Future Prospects
In summary, with its unique advantages and remarkable application results, the KFM activated media filter holds broad application prospects in the field of oilfield wastewater treatment. With ongoing technological advancements and continuous equipment optimization, it is believed that the KFM filter will play an even more critical role in the future, contributing significantly to the sustainable development of oilfields and environmental protection.
