1. ENHANCED SOLIDS SEPARATION
Polymers improve the separation of solids from liquids in manure, making the most digestible material available for biogas production.
Studies have shown that polymer addition can increase total solids removal efficiency by over 80%, optimizing the concentration of volatile solids for anaerobic digestion.
2. BOOSTED BIOGAS YIELD
Polymers increase the availability of organic matter, enhancing microbial breakdown in digesters and improving methane production.
Biogas production can increase by 10-15% when manure is pre-treated with polymers.
3. HIGH-QUALITY DIGESTATE
Polymers retain more nutrients like nitrogen and phosphorus in the digestate, creating a superior fertilizer product post-digestion.
Nutrient concentration in digestate improves by up to 20% when manure is pre-treated with polymers.
4. REDUCED INHIBITORY COMPOUNDS
Ammonia and other compounds in untreated manure can inhibit methane production. Polymers help neutralize these inhibitors, leading to more efficient biogas production.
Polymer pre-treatment reduces ammonia concentration by up to 30%, stabilizing the digestion process.
5. LOWER ENERGY COSTS
Polymer-treated manure requires less energy to process, reducing the operational energy demand for mixing and pumping the slurry.
Energy savings of up to 25% have been observed due to easier handling and improved flow characteristics of polymer-treated manure.
