Fracturing flowback water in oil and gas development presents complex challenges due to high viscosity, severe emulsification, and reliance on chemical treatments that increase costs and secondary pollution. Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) has developed an integrated technology system combining CDFU (Cyclonic Dissolved-gas Flotation Unit), CDOF (Ozone Catalytic Oxidation for Deep Gel Breaking & Viscosity Reduction), and KFM filtration. This system achieves purely physical demulsification, high-efficiency oil and solids removal (>90%), rapid gel-breaking (≤15 minutes), zero chemical addition, and on-site skid-mounted deployment. Proven in Xinjiang oilfields, SINOKLE’s solution reduces energy and operational costs, minimizes hazardous sludge, enables water reuse, and provides both environmental and economic benefits, offering a sustainable, low-carbon approach for high-quality oilfield wastewater management.2026/05/13
Under the global push for “Net-zero,” industrial wastewater treatment faces critical challenges in energy consumption, chemical usage, and sludge management. Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) addresses these issues with its CDFU ultra-fine bubble flotation unit and CDOF ozone oxidation system. These technologies achieve minute-level high-efficiency purification, single-stage oil removal above 90%, suspended solids removal above 85%, stable effluent oil content below 5 mg/L, reduced facility footprint, zero chemical addition, and resource recycling. Validated in real-world projects, these systems reduce energy consumption, operational costs, and carbon emissions while generating economic value from recovered oil, offering a practical, sustainable, and low-carbon solution for petrochemical, coking, and power industries.2026/05/11
Flotation technology, especially Dissolved Air Flotation (DAF), is a key industrial water treatment method for separating oil, suspended solids, and emulsified contaminants. Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) has developed the Cyclonic Dissolved-gas Flotation Unit (CDFU), combining ultrafine bubbles, cyclonic centrifugal separation, and intelligent control for highly efficient, eco-friendly, and cost-reducing treatment of oily wastewater. The skid-mounted, corrosion-resistant system delivers rapid separation (1–3 min/stage), minimizes sludge, resists shock loads, and ensures stable effluent quality (<10 mg/L oil, <20 mg/L solids), making it ideal for oilfields, refineries, and high-salinity or highly emulsified wastewater scenarios.2026/05/08
Leachate from landfills and incineration is a highly concentrated, toxic, and complex wastewater, posing severe environmental challenges. Traditional methods often face inefficiency, high costs, and secondary pollution risks. Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) has developed the CDOF (Cyclonic Dissolved Ozone Flotation) technology, combining DAF, micro-bubble generation, and ozone oxidation, offering a membrane-free, zero-concentrate, and highly efficient solution. The process ensures rapid oxidation and separation, minimizes sludge, reduces operating costs, and delivers stable, odorless, and colorless effluent. With intelligent control and full-volume treatment, CDOF provides a green, cost-effective solution for sustainable leachate management and supports zero-waste city initiatives.2026/05/06
Hydrocyclones are essential equipment in the extraction liquid treatment process in industries like petrochemicals and oilfields, known for their energy-saving, non-powered drive, and highly efficient oil-water-solid separation. SINOKLE has advanced the hydrocyclone's design over the past decade, evolving it from a simple device to a high-efficiency tool adaptable to various operational scenarios. With improvements in flow stability, corrosion resistance, and intelligent control systems, SINOKLE's hydrocyclones offer improved separation performance, reduced operational costs, and enhanced adaptability for different extraction liquid conditions. These advances make hydrocyclones a critical technology for achieving greener, more efficient, and cost-effective operations in the oil and petrochemical sectors.2026/04/29
