The new UASB PLUS anaerobic reactor has been launched.
2025-11-25
The UASB PLUS, a new type of anaerobic reactor independently developed by our company, stands as a flagship product representing the third generation of highly efficient anaerobic treatment technology and demonstrates remarkable technical advantages in the field of wastewater treatment. With the core objective of breaking through the bottlenecks of conventional processes, this equipment achieves dual optimization—enhancing treatment efficiency while reducing operating costs—through systematic, innovative design. The technological prototype was born from five years of rigorous operational data tracking and analysis of traditional UASB reactors; the R&D team accumulated more than 200 sets of process parameter samples and identified key issues inherent in conventional three-phase separators, including insufficient gas–liquid separation efficiency and significant fluctuations at the solid–liquid interface. In response to these critical technical challenges, the R&D team leveraged computational fluid dynamics (CFD) simulation technology to conduct three-dimensional modeling and analysis of the internal flow field within the separator. After 37 rounds of structural optimization iterations, they ultimately developed a modular separation unit protected by independent intellectual property rights. This innovative structure features a composite design incorporating double‑layer inclined plates and swirl‑inducing guide vanes; by optimizing the gradient of the gas–liquid upward flow velocity, the biogas collection efficiency was boosted to over 98%. At the same time, a dynamic liquid level control system was employed to keep the interface between the sludge settling zone and the clarification zone within a tolerance of ±5 mm, significantly enhancing the stability of effluent water quality. Compared with conventional equipment, the UASB PLUS has achieved three major technological breakthroughs: First, it adopts a standardized, modular design, allowing the processing capacity of a single unit to be flexibly configured within a range of 50–500 m³/d according to actual needs, while reducing the equipment’s footprint by 40%; second, through optimized distribution systems and reflux devices, the organic loading has been increased to 8–12 kg COD/(m³·d), representing a 60% improvement over traditional processes; and third, by innovatively employing corrosion‑resistant alloy materials and a detachable structural design, the equipment’s service life has been extended to over 15 years, while maintenance costs have been reduced by 35%. To date, this technology has been granted three national invention patents and has undergone engineering application validation across 12 industries, including food processing, pharmaceuticals, and chemicals. Measured data show that the COD removal rate remains consistently above 92%, and the effluent water quality meets the Class I standard stipulated in the “Integrated Wastewater Discharge Standards.”
