Abstract

Three innovative technical solutions for sludge minimization in wastewater treatment are under investigation in Routes project ("Novel processing routes for effective sewage sludge management") co-funded by the European Commission in the framework of the Seventh Framework Programme: 1) the use of Sequencing Batch Biofilter Granular Reactor (SBBGR) based technology, 2) the integration of membrane bioreactors with anaerobic side-stream process (MBR+AnSSR), and 3) the adoption of alternate cycles process applied in the sludge line (ACSL).The results obtained have shown that: 1) SBBGR is able to reduce up to 75% the sludge production during raw municipal wastewater treatment, and to offer satisfactory performances allowing the discharge limits to be met; 2) MBR+AnSSR offers a sludge production reduction comparable or even greater than that obtained in a conventional system (MBR + aerobic digestion), and 3) ACSL permits to obtain an Observed Yield reduction on average equal to 46% compared with the expected one, without a worsening of the final effluent quality.
