The performances of a semi-industrial-scale membrane bioreactor to treat dilute swine wastewater were investigated on a 3 month running period. The treated water was directly reused in the piggery for flushing purposes. The pilot was proved to have good performances in terms of ammonium removal (99%), and COD removal (86%), despite an accumulation of heavy metals in the biological tanks (up to 17 mg/L for zinc and up to 115 mg/L for copper). 79% of the total phosphorus was eliminated through the process, 61% via centrifugation and 18% by biological uptake. The pilot showed a good adaptability to the variations of the loading rates of dilute swine wastewater's major components (COD, TN, TP, heavy metals).

The aim of this work was to evaluate the long-term performance of a Membrane Bioreactor (MBR) that operated continuously for 2.5 years and to assess membrane fouling and biomass activity under various operating conditions. Furthermore, a method for the characterisation of influent wastewater was developed based on its separation into various fractions. The MBR system operated at the solids retention times (SRT) of 10, 15, 20 and 33 days. The increase of SRT resulted in a decrease of the fouling rate associated with the reduction of extracellular polymeric substances. Moreover, the SRT increase resulted in a significant reduction of the Oxygen Uptake Rate (OUR) due to the lower availability of substrate and in a notable decrease of the maximum OUR since high SRT allowed the development of slower growing microorganisms. Biomass consisted of small flocs due to extensive deflocculation caused by intense aeration. Finally, the method developed for wastewater characterisation is straightforward and less time consuming than the usual method that is employed.

A modularized microbial fuel cell system can effectively treat primary effluent and use the produced energy to offset part of its energy consumption.
