Oxygen Generator for Wastewater Treatment
In the field of sewage treatment, efficient aeration process is the core of biochemical treatment, which is directly related to the quality of the effluent and operating costs. The special oxygen generator for wastewater treatment launched by Shenger Gas uses advanced pressure-switching adsorption (PSA) technology to directly separate high-concentration oxygen from the air, replacing traditional air aeration or liquid oxygen, which can significantly improve sewage treatment efficiency and reduce comprehensive operating costs. This system is an ideal choice for municipal sewage and industrial wastewater treatment plants to achieve energy saving and consumption reduction and stable compliance.
Core product advantages
- Improve treatment efficiency: Provide high-concentration oxygen of 90%-95%, greatly increase oxygen mass transfer efficiency, effectively promote aerobic microbial activity, accelerate the degradation rate of BOD/COD, especially suitable for high-load wastewater and upgrade and transformation projects.
- Significantly reduce energy consumption: Compared with traditional blower aeration, it can save up to 30%-50% of energy consumption, and the return on investment is short. Compared with liquid oxygen, there is no evaporator required, no evaporation loss, and the operating cost is extremely low.
- Stable and reliable operation: fully automatic control system, one-click start and stop, real-time monitoring of oxygen purity, pressure and flow, ensuring seamless connection with the sewage treatment process, and continuously supplying a stable oxygen generator for wastewater treatment.
- Modular and compact design: The core components adopt internationally renowned brands, have a compact structure and small footprint, and support container-type or shed installation to adapt to various on-site environments.
