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
Tar wastewater treatment, especially in industries like petrochemicals and coal chemicals, faces significant challenges due to its stable emulsion, complex composition, and high shock resistance. Traditional methods such as gravity settling, air flotation, and chemical demulsification struggle with high oil content and emulsification, resulting in environmental and operational inefficiencies. SINOKLE's innovative solution utilizes its Cyclonic Dissolved-gas Flotation Device (CDFU), employing ultra-fine micro bubbles and cyclonic centrifugal separation to break stable emulsions without the use of chemical agents. This pure physical separation approach not only reduces waste but also enables efficient dewatering, resource recovery, and adaptability to fluctuating wastewater quality, addressing the industry's key pain points. SINOKLE’s solution offers a sustainable, low-carbon path for high-efficiency, environmentally-friendly tar dewatering.2026/04/27
As global energy transitions towards net-zero goals, oilfield development is evolving with a focus on efficient extraction, low-carbon operations, and intelligent management. Oilfield wastewater treatment plays a critical role in maintaining resource recycling, ecological protection, and the stable operation of production systems. In China, traditional treatment methods are hindered by fluctuating water quality, decentralized systems, high manual labor, and substantial chemical usage. Shenzhen Clear Science & Technology Co., Ltd. (SINOKLE) has developed a cloud-based intelligent monitoring platform, integrating IoT, big data, AI, and edge computing, to enhance oilfield wastewater treatment. This platform enables unmanned operation, remote monitoring, automatic process regulation, and proactive fault prediction. By combining advanced technologies such as the Coalescing Oil-Water Separator and Cyclonic Dissolved-gas Flotation Unit (CDFU), SINOKLE offers a comprehensive, efficient, and sustainable solution that supports green development, cost reduction, and operational stability.2026/04/24
