Is High Ammonia Killing Your Digester Performance?
Poultry manure and litter are rich in nitrogen, but as they break down, they release high concentrations of Total Ammoniacal Nitrogen (TAN). This leads to:
Inhibited Methane Production: Reduced biogas output and lost energy revenue.
Process Instability: Frequent “sour” digesters and costly maintenance.
Regulatory Hurdles: Difficulty meeting nitrogen discharge limits.
OTAR® : A Proven Low-Carbon Solution
The Circular Economy Solution for Poultry Waste-to-Energy
The OTAR® platform is a modular, thermal stripping system designed to integrate directly with your existing AD infrastructure. By removing ammonia from the digestate, you unlock the full energy potential of your organic feedstock.
Boost Biogas Efficiency
Lowering ammonia levels allows for higher organic loading rates.
Energy Neutral Operation
OTAR® utilizes waste heat from your existing biogas engines (CHPs).
Resource Recovery
Don’t just treat waste—produce commercial-grade ammonium sulphate or ammonium hydroxide for use as fertilizer.
OTAR® at a Glance : Optimized for Thermal Resource Recovery
Our technology uses a low-temperature thermal process to move ammonia from the liquid phase to the gas phase. Depending on your site requirements, we offer several configurations:
Variant 3: Produces 40% concentration Ammonium Sulphate—ideal for direct agricultural resale.
Variant 4: Features advanced heat recycling for maximum thermal efficiency using CHP waste heat.
