- Full-scale thermal pre-treatment is expanding worldwide for enhanced digestion of sewage sludges, allowing higher solids throughput/reduced time, but leads to ammonia-inhibition. Our novel ammonia removal resulted in 54% increased energy-recovery and a growth of 6x-methanogens & bacteria(2x), contradicting current thinking. Work led to the WG-SMART-CIRCLE-WP4 project (8 partners including DCWW&CSIC-Spain (£350k, >£350k-partner contributions); a commercial pilot trial project £55k with DCWW/Ultrawaves and a KESS PhD-DCWW (£65k). Additional income from the new methodology for 1-plant for DCWW >£1.5M/year, and benefits would replicate in other plants. Methodology is expanding to numerous industrial environments including odour removal (FORD and GP Biotec).
