At the end of December 2023, our company was successfully awarded the Integrated Produced Water Treatment project for the No.5 Production Plant of Changqing Oilfield. Based on thorough analysis of the influent water quality and effluent requirements, we specifically selected a Combined Air Flotation and Filtration Treatment Process. The Integrated Produced Water Treatment Package was delivered to the site as scheduled. After on-site installation, commissioning, and trial operation, the system has been functioning normally with effluent quality fully meeting all specified requirements.

In late April 2024, our company was once again awarded the contract for an Integrated Produced Water Treatment Package for the No.12 Production Plant of Changqing Oilfield. Based on the produced water quality parameters, we implemented a Combined Coalescing Oil and with Micro-electrolysis Oxidation Process. To minimize on-site installation workload, the treatment equipment was designed as an integrated modular system. By November 2024, this Integrated Produced Water Treatment Package completed on-site positioning and installation, achieving successful handover to the owner. Following equipment arrival。
