What is HLR Technology?
HLR (High Rate / High Load Digestion) is an advanced anaerobic digestion technology designed to process high-strength organic waste with significantly higher organic loading rates and shorter retention times compared to conventional systems.
This technology employs specialized reactor designs and optimized process conditions to achieve superior biogas yields while maintaining a compact footprint. HLR systems are particularly effective for industrial waste streams with high Chemical Oxygen Demand (COD) concentrations, delivering the highest returns on investment.
How HLR Technology Works
Understanding the high-performance process flow of HLR-based Bio-CNG production
High-COD Feedstock
Industrial waste with high COD (10,000-50,000 mg/L) is pre-treated and prepared for rapid digestion without excessive dilution.
High-Rate Digestion
Optimized reactor design with enhanced mixing and temperature control enables high organic loading rates (5-10 kg VS/m³/day) with short HRT (5-10 days).
Superior Biogas Yield
Advanced process control and optimized conditions result in higher methane content (60-65%) and superior biogas yields (0.6-0.8 m³/kg VS).
Efficient Upgrading
High-quality biogas is efficiently upgraded to >96% methane, compressed, and stored as Bio-CNG, maximizing energy recovery from waste.
Key Features & Benefits
Highest Returns
Superior biogas yields and faster processing times result in higher revenue generation and improved return on investment compared to conventional systems.
Smaller Footprint
Compact reactor design with shorter retention times requires less land area, making it ideal for space-constrained industrial locations.
High Processing Capacity
Can handle 2-3 times higher organic loading rates than conventional systems, processing more waste in less time and space.
Superior Gas Yield
Optimized process conditions deliver higher methane content and biogas yields, maximizing energy recovery from industrial waste streams.
