“…These were achieved without the addition of vitamins, minerals and carbon sources other than the whey powder in a low‐buffer capacity solution. By comparison the maximum current densities reached in this study are progressing towards the value of 0.79±0.13 mA cm −2 found with the similar graphite papers, but with 10 mM acetate in 50 mM phosphate buffer solution …”

“…By comparison the maximum current densities reached in this study are progressing towards the value of 0.79 � 0.13 mA cm À 2 found with the similar graphite papers, but with 10 mM acetate in 50 mM phosphate buffer solution. [20] In order to investigate whether or not the selection and enrichment process as well as the use of different potentials (Schematic overview was in SI 1 Figure S2) had a statistically significant impact, two sample t-test analysis (SI 7 Table S3) was performed. Although the t-tests indicate that there are some statistically significant differences between groupings, i. e. based on grouping by potentials or sequences or both, of individual parameters, in general the performance reached a plateau when proceeding from sequence 1 to 2.…”

Investigating Community Dynamics and Performance During Microbial Electrochemical Degradation of Whey

Whey is a main by‐product of the dairy industry and is difficult to valorise for small and medium enterprises. Microbial electrochemical technologies could be the key for these enterprises to exploit this current waste product. Whey removal and conversion to electrical current was investigated at microbial anodes using potentiostatically controlled half‐cell experiments. The anodes were fed with a whey solution containing ca. 1 g L−1 COD. This can be reliably cleaned with average removal efficiencies of 65.8±10.9 %. The removal coincided with maximum current densities of 0.31±0.06 mA cm−2 and Coulomb efficiencies of 37.1±10.8 %. The anodes are based on a robust complex microbial community. This was established in bioelectrochemical reactors by end of four batch cycles showing an efficient niche differentiation from the following successive enrichments. The microbial analysis revealed a division of labour with mainly planktonic microorganisms degrading the complex whey components by fermentation to organic acids, part of which are subsequently used by the electroactive bacteria at the anode. The results show the need for deciphering microbial structure‐function relationships for future process steering as well as engineering approaches.

“…Each cycle consisted of successive phases including: 5 min for filling influent, 85 min for anoxic process, 300 min for aeration reaction, 15 min for settling, 5 min for decanting the effluent and the rest of the time for idling. Idling time was used to control the HRT of the reactor depending on the requirement of treatment, as similar reported by Seesuriyachan et al (2009). Moreover, it also has certain ability to enhance phosphorus removal but with low N 2 O generation .…”

“…The lower maximum OLRs also reduced the SBR granular sludge effi ciency (17). In a bench-scale SBR, raw industrial dairy wastewater was treated with Lactobacillus casei TISTR 1500 (62). Microaerobic conditions maintained in the SBR allow for biomass accumulation in large amounts, leading to 85 % lactose reduction via rapid fermentation and subsequent protein coagulation by 90 %.…”

SummaryThe milk processing industry is one of the world's staple industries, thus the treatment possibilities of dairy effl uents have been att racting more and more att ention. The purpose of the paper is to review contemporary research on dairy wastewater. The origin, categories, as well as liquid by-products and general indicators of real dairy wastewater are described. Diff erent procedures applied for dairy wastewater management are summarised. Att ention is focused on in-factory treatment technologies with the emphasis on biological processes. Aerobic and anaerobic methods with both their advantages and disadvantages are discussed in detail. Consecutive anaerobic and aerobic systems are analysed, too. Finally, future research niches are identifi ed.
