500 m³ Double Membrane Gas Holder Project Successfully Completed in Dezhou, Shandong
Recently, the 500 m³ double membrane gas holder supplied and installed by Qingdao Haiyue Membrane Structure Co., Ltd. for a biological wastewater treatment project in Dezhou, Shandong, was successfully completed and passed the gas-tightness test on the first attempt. This milestone marks the completion of the project’s biogas collection, buffer storage, and constant-pressure supply system, providing a stable and reliable gas source for subsequent biogas power generation and heating.
The project treats a large volume of wastewater with a high organic load, continuously generating biogas during the anaerobic treatment process. To address the imbalance between biogas production and consumption, as well as limited peak-shaving capacity, the project was equipped with a 500 m³ double membrane gas holder. Its storage capacity automatically adjusts according to variations in biogas production, effectively balancing supply and demand while reducing biogas flaring and energy waste.
Despite a tight construction schedule and multiple teams working simultaneously on-site, Haiyue’s project team carefully coordinated the installation and strictly controlled every critical stage, including bottom membrane laying, inner membrane installation, outer membrane fastening, electrical control integration, and system commissioning. The installation was completed ahead of schedule, with the gas-tightness and overall operating performance meeting all acceptance requirements and earning high recognition from the project owner.
