Part 1: Summary
🌐🔄 END-O-SLUDG: Transforming Sludge Management through Novel Processes and Market Development
🌍Methodology:
▶️ Investigations focused on sludge reduction, treatment, digestion intensification, competitive exclusion, downstream processing, bio-granule and Organo-Mineral Fertilizer (OMF) production, market development activities, and management and sustainability studies.
▶️ A range of technologies and approaches were employed, including Dissolved Air Flotation (DAF), Inverted Phase Fermentation (IPF), micro-milling, ion exchange, reverse osmosis, and sustainability assessment methods.
🌍 Key Findings:
▶️ DAF was effective in reducing sludge volume and TSS removal, with the potential for energy savings.
▶️ IPF was found to be effective in splitting watery sludge into solid and liquor fractions, enhancing biogas conversion.
▶️ A crude biopolymer product, BIOPOL, was discovered, showing promise as a co-precipitant for phosphorus recovery.
▶️ Micro-milling was effective in treating sewage sludge, achieving high organic matter solubilization.
▶️ IPF and micro-milling showed potential for digestion intensification, increasing biogas production.
▶️ A potential probiotic culture was identified to suppress E. coli growth in digested sludge cake.
▶️ Reverse osmosis showed encouraging results for simultaneous recovery of ammonia and phosphate.
▶️ A two-stage process was developed for bio-granule and OMF production, utilizing waste heat for sustainable sludge drying.
▶️ OMF showed similar yields to conventional fertilizers in farm-scale trials, with minimal impact on soil and earthworms.
▶️ OMF could be accurately spread using commonly available fertilizer spreaders.
▶️ Production and commercialization of sludge derivatives can provide economic benefits and reduce sludge disposal costs.
🌍 Conclusion and Keynote Summary:
▶️ The END-O-SLUDG project has made significant progress in developing innovative solutions for sludge management, including volume reduction, energy recovery, nutrient recycling, and the production of marketable sludge derivatives.
▶️ The project's findings have implications for sustainable sludge management, economic opportunities, and the reduction of carbon dioxide emissions.
▶️ The development of OMF as a potential End of Waste product has the potential to transform the way sludge is managed and utilized, creating a more circular and sustainable approach to wastewater treatment.
