Abstract [en]

Purpose The MBBR solution has been applied for the textile wastewater treatment. However, in order to develop cost-effectivesolutions, waste biomass can be used as carrier. Rice husks are agricultural waste which have been used as an adsorbent of dyes;besides, they can provide and sustain suitable microorganism communities for the degradation of dyes. This study aimed toevaluate the biodegradation of the azo dye Direct Red 75 in two treatment systems with different carriers.Methods Bioreactor Awas composed by an anaerobic bioreactor filled with Kaldnes K1 carriers employed in the MBBR technologyand the study was performed in 2 different temperatures, 30 ± 0.5 °C and 21 ± 2 °C. Biofilter B was composed by a sequencedanaerobic-aerobic system with rice husks as carriers and this study was performed at 21 ± 2 °C. The rice husks was also employed asa source of microorganisms in both systems. Decolourization, surface area of the carriers and other parameters were analysed.Results Biofilter B showed high rates of decolorization, mainly over 90% in all HRT tested (24, 48 and 12 h), presenting itself asa stable system, whereas Bioreactors A showed better performances with 48 h of HRT, about 85%for A at 30 ± 0.5 °C and 45%at21 ± 2 °C. With a similar amount of carriers, analyses showed that rice husks had a much larger surface for microorganisms togrow on than Kaldnes K1.Conclusion The Biofilter B is a worthwhile system to be investigated and applied for the decolourization of textile wastewatertreatment; for instance, in developing countries.

Abstract [en]

The Baltic Sea is an over-fertilized inland sea; the blue mussels have potential to absorb nutrients as well as being a source of renewable energy in the form of biogas. The aim of this study was to evaluate technology to utilize blue mussels for biogas production in a pilot scale. Blue mussels (Mytilus edulis) were anaerobically digested in a two-stage digestion process (430 L), consisting of a percolation bed and an up-flow anaerobic sludge blanket reactor. Frozen mussels with shells were placed in the percolation bed and digestion was performed at 36 oC during 37 days. The methane potential achieved with this technique was 310 L kg-1 volatile solid substances (273.15 K, 101.3 kPa). This result suggests that blue mussels can be efficiently digested in a larger scale and have the potential of contributing to a sustainable energy mix in the Baltic region and at the same time decrease the eutrophication of the Baltic Sea.  No addition of nutrients and no pretreatment of the mussels (peeling) were needed.

Abstract [en]

The investigation focused on obtaining experimental results from the self-heating properties of different softwood samples during lab-scale storage. The samples investigated were a mixture of dried soft wood sawdust, softwood pellets 8 mm in diameter, and aged softwood sawdust stored outdoors for three months. Isothermal calorimetry was used to measure the heat released from the biomass samples and assess the contribution to self-heating during storage. Softwood samples were stored at 20 °C, 50 °C, 55 °C and 60 °C, and the metals manganese, copper and iron were added as a water solution to investigate if the presence of metals would increase the risk of self-heating. For most sample series, the highest levels of heat release were found after approximately 10 days of storage; sample series stored at 50 °C displayed the highest levels. The addition of copper resulted in levels of heat release 135% higher than samples without metal added.

Abstract [en]

Textile dying processes often pollute wastewater with recalcitrant azo and anthraquinone dyes. Yet, there is little development of effective and affordable degradation systems for textile wastewater applicable in countries where water technologies remain poor. We determined biodegradation of actual textile wastewater in biofilters containing rice husks by spectrophotometry and liquid chromatography mass spectrometry. The indigenous microflora from the rice husks consistently performed >90% decolorization at a hydraulic retention time of 67 h. Analysis of microbial community composition of bacterial 16S rRNA genes and fungal internal transcribed spacer (ITS) gene fragments in the biofilters revealed a bacterial consortium known to carry azoreductase genes, such as Dysgonomonas, and Pseudomonas and the presence of fungal phylotypes such as Gibberella and Fusarium. Our findings emphasize that rice husk biofilters support a microbial community of both bacteria and fungi with key features for biodegradation of actual textile wastewater. These results suggest that microbial processes can substantially contribute to efficient and reliable degradation of actual textile wastewater. Thus, development of biodegradation systems holds promise for application of affordable wastewater treatment in polluted environments.

Abstract [en]

The research is focused on evaluation of substrates not commonly used for biogas production and the development and optimization of processes adjusted to these substrates. This study deals with evaluation of sea weeds (Saccharina Lattisima and Laminaria digitata). Biomethane potential tests (BMP) have shown the methane potential of the algae to be 180-440 l CH4/kg organic material. These potentials are in the same range as potentials found for commonly used substrates such as sewage sludge and slaughterhouse waste. Sampling of produced biogas, substrate and digest were performed by using Solid Phase Microextraction (SPME) followed by analysis by a Gas Chromatograph with a Mass Spectrometrer (GC-MS) in order to develop a method to be able to characterize, monitor and possibly control the process.

Abstract [en]

Azo dye degradation occurs by means of the oxidation–reduction reactions which have the azo dye acting as final electron acceptor. Some carbon sources can act as electron donors because the products of their metabolism act as redox mediators. In order to enhance the dye biodegradation process, the present study aims to evaluate the decolorization of an artificial wastewater, containing the azo dye Direct Red 75 (DR75), led by a microbial consortium from rice husks, testing the effect in the process of glucose and yeast extract as carbon sources. Samples with and without 0.1 M Sodium phosphate buffer were also analysed. The decolorization was measured by means UV-VIS spectrophotometry. The percentage of decolorization of the samples over the time indicates that the sample with yeast extract, rinse water of rice husks and without buffer presented the best decolorization rate, about 80%. Therefore, the results presented in this study may also suggest that yeast extract is a better carbon source for dye biodegradation than glucose.

Abstract [en]

In the present study the degradation of two common azo dyes used in dye houses today, Reactive Black 5 and Reactive Red 2 was evaluated in biofilters. In two experiments, bioreactors performed over 80% decolorization at a hydraulic retention time of only 28.4 h with little production of metabolites. Molecular analyses showed a diverse and dynamic bacterial community composition in the bioreactors, including members of the Bacteroidetes, Acinetobacter (Gammaproteobacteria) and Clostridium (Firmicutes) that possess the capacity to reduce azo dyes. Collectively, the results indicate that the development of mixed bacterial communities from natural biomaterials contributes to an efficient and robust degradation performance in bioreactors even at high concentration of dyes.

Abstract [en]

The purpose is to develop a complete microbiological model system for the treatment of wastewater

from textile mills in developing countries. Arti

fi

cial wastewater was treated by microorganisms growing

on wood shavings from Norway spruce during unsterile conditions. The microorganisms were inoculated

from forest residues. Mixtures of the azo dyes Reactive Black 5 and Reactive Red 2 were degraded in

batch as well as continuous experiments. Reactive Red 2 mixed with the anthraquinone dye Reactive

Blue 4 was also treated in the continuous system. The system consisted of three reservoirs

of

each dye in the continuous system and the retention time was approximately 4 days and 20 h per

reservoir. Samples from the process were analysed with spectrophotometer and LC/MS to monitor the

degradation process. 86-90% of the colour was removed after a treatment of 4 days and 23 h in the

continuous process. Two metabolites were found in the outlets of reactors one and two, but they were

degraded to below the detection limit in the aerobic reactor.
