This project is located in the Bohai Sea, China, with CNOOC's Bohai offshore production platform as the client. Produced water generated during offshore oil and gas development is one of the primary industrial wastewater sources. It contains crude oil, suspended solids, and salts, and if discharged without adequate treatment, would cause serious marine pollution.

Sinokle deployed its proprietary CDFU Cyclone Dissolved Air Flotation unit, tailored for offshore platform produced water. The CDFU technology combines cyclone separation with dissolved air flotation, generating large quantities of micro-bubbles that attach to oil droplets and suspended solids, enabling rapid floatation and separation. The technology features a compact footprint, high efficiency, and stable operation — ideal for the constrained spaces and demanding conditions of offshore platforms.

This project is a landmark reference case for Sinokle in the field of offshore oil and gas produced water treatment, fully validating the high efficiency and stability of the CDFU technology in marine environments, and providing reliable technical support for protecting the marine ecosystem and advancing green development of offshore oil and gas fields.
