AS+ Technology

AS+ is an advanced variant of the conventional activated sludge process, engineered to deliver significantly improved treatment performance (BOD/COD removal >92%, TSS removal >95%, ammonia removal >85%) while reducing energy consumption by 15-25% and sludge generation by 20-35% compared to conventional systems. It builds on decades of biological treatment knowledge with modern process optimizations including fine bubble aeration, selector zones for bulking control, and extended sludge retention times (SRT 15-30 days) for stable nitrification.

The technology employs enhanced aeration strategies with oxygen transfer efficiencies of 25-35% (vs. 15-20% conventional), optimized F/M ratios (0.15-0.25 kg BOD/kg MLSS/day), and intelligent dissolved oxygen control (maintaining 1.5-2.5 mg/L) to achieve high-rate removal of organics and nutrients. Typical volumetric loading rates of 0.4-0.8 kg BOD/m³/day with hydraulic retention times of 8-16 hours ensure robust treatment even under shock loading conditions. The result is a treatment system that consistently produces high-quality effluent meeting stringent discharge standards or suitable for industrial reuse applications.

AS+ systems are designed for scalability from 50 KLD to 500 MLD capacities, making them suitable for both large municipal treatment plants and compact industrial installations. Energy consumption typically ranges from 0.5-1.0 kWh/m³ treated, with advanced automation reducing operator intervention to minimal supervision levels. The technology adapts to varying influent characteristics (COD:BOD:N ratios of 100:50:5 to 100:80:10) while maintaining stable performance through robust mixed liquor suspended solids management (MLSS 2,500-4,000 mg/L) and effective sludge age control.
