Advanced Treatment Technologies for Shale Oil Produced Water: Innovations in Oil-Water Separation and Environmental Efficiency
The oil-contaminated wastewater in shale oil production mainly originates from processes such as dry distillation, washing, cooling circulation, and tank dehydration. Its characteristics include high organic content, high ammonia nitrogen concentration, the presence of various pollutants, and difficulty in biological degradation. Treatment methods include oil separation, demulsification flotation, biological treatment, physicochemical treatment, and advanced treatment processes. However, challenges remain, including low oil-water separation efficiency, equipment corrosion and clogging, insufficient processing capacity, high environmental risks, and the complex treatment of heavy oil and polymer-driven produced water.
Although traditional processes still face many challenges in treating shale oil contaminated wastewater, recent years have seen continuous technological upgrades. The following introduces an innovative technical solution developed by the Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) to address these issues. The solution proposes new pathways to enhance oil-water separation efficiency, reduce equipment wear, and optimize treatment processes.
Through patented technologies such as CDFU, CDOF, and the patented KFM Activated Media Filter, it is possible to significantly reduce emulsified oil, suspended solids, and particles in shale oil produced water. Different processes are selected according to discharge requirements, achieving efficient treatment and meeting discharge standards. The process has the following advantages:
1. Strong resistance to shock conditions, with stable and reliable performance.
2. No chemical additives, purely physical demulsification, no aging oil, no secondary pollution, good environmental benefits.
3. Short process flow, small footprint, fewer moving parts, simple operation, low operating costs.
4. Sealed container that overcomes the environmental impact of traditional flotation tanks, ensuring efficient, continuous, and stable operation.
