Abstract

International audience; Livestock waste has a lot of influence on nitrogen contamination in public water body, in Japan, because it is produced as much as 20% of the total amount of industrial waste generated in the country. Commonly, liquid fractions that was produced by solid-liquid fraction of livestock waste, is treated by activated sludge process and then discharged to public water body. According to government sources, 61% of such swine wastewater is aerobically treated. An activated sludge model (ASM)-type model considering BOD and N removal was implemented including nitrite as intermediate, free ammonia and free nitrous acid as potential inhibitors and temperature as process parameter during swine wastewater treatment. Aeration condition is a key factor on nitrogen removal in the activated sludge process. Therefore, simulations were performed with focusing on aeration conditions: continuous and intermittent aeration with various aeration intensity; influent swine wastewater BOD/N ratio of 2, 3 and 4. In the continuous aeration condition, when DO was low, N was mainly removed through the nitrite short cut in simultaneous nitrification-denitrification. In intermittent aeration condition, N was removed at broader DO conditions during aeration than previously assessed for continuous aeration. However, electrical energy consumption to achieve satisfactory N removal was almost same between two aeration conditions. When the BOD/N ratio was set at 4, achieving satisfactory N removal was easier than BOD/N ratio of 3, and 2, at both conditions. When the BOD/N ratio was set at 2, critical DO control was required to achieve satisfactory N removal, therefore in such case, adding post-treatment for nitrogen removal like anammox process, after the activated sludge process would be practical.

Abstract

International audience; An ASM-type model considering BOD and N removal was implemented including nitrite as intermediate, free ammonia and free nitrous acid as potential inhibitors and temperature as process parameter during swine wastewater treatment. Simulations were performed at various conditions: continuous and intermittent aeration; influent swine wastewater BOD/N ratio of 2, 3 and 4. Under continuous aeration and low DO, N was mainly removed through the nitrite short cut in simultaneous nitrification-denitrification. Under intermittent aeration, N was removed at broader DO conditions during aeration than previously assessed for continuous aeration. In both aeration conditions, critical DO control was required to achieve satisfactory N removal, particularly when the BOD/N ratio of the wastewater was set at 2. This study assesses those conditions needed to meet the N effluent standards in AS swine wastewater treatment plants, and to identify those cases when post-treatment will be needed.

Abstract

International audience; Cultivation of microalgae in wastewater and digestate has received special attention during the last years due to the potential for nutrient, CO2 and/or heat recovery and recycling. However, understanding microalgae-bacteria interactions remains a major concern for process operation and control. This paper aims to develop a new mathematical process model in the IWA activated sludge model (ASM) framework, including microalgae cultivation, heterotrophic and autotrophic bacteria interactions, as well as pH dynamics. The model should allow to develop optimization and control strategies of microalgae processes for nutrient, CO2 and heat recovery. In this paper, the model was verified and calibrated under dynamic conditions. Mass balances were closed for nitrogen, phosphorus and carbon elements, whereas also the overall dynamics were satisfying. Finally, future research efforts were identified.

Abstract

This paper is a discussion proposal of structural model of organic matter hydrolysis (in aerobic and anaerobic bioprocesses) based on laboratory and model results. Indeed, the hydrolysis mechanism is mechanistically not well understood. Consequently, models are sometimes not appropriate to describe experimental results. Where there are multiple fractions, a model that considers simultaneous degradation of the substrates may not have the resolution to separate the different kinetics. In this paper, we assess sequential extractions to evaluate this as an alternative to simultaneous analysis.

Abstract

International audience; Microalgae culture for extraction of nutrient from digestate was studied at laboratory scale to determine the influence of turbidity of influent, light provided, N:P of the influent, CO2 supplementation and solid retention time on microalgae productivity and associated N removal processes. The experimental results obtained in batch and semi-continuous mode showed the importance of turbidity of influent combined with light intensity on the microalgae roductivity compared to the impact of the level of CO2 supplementation and N:P ratio. Additionally to N assimilation by microalgae, nitrification-denitrification was identified as a major N pathway with N removal at least equal to N assimilation. However, limitation of nitrification process appears possible through the N:P ratio of the influent. The evolution of microalgae communities observed during these trials highlighted the interest of using mix culture allowing a better adaption to the conditions evolutions. Finally, all experimental results were used to build and calibrate a model simulating microalgae growth using nutrients from digestate and such a model was used to design a raceway pond treating digestate from a commercial farm producing 4000 pigs per year.

Abstract

International audience; Psychrophilic methanisation is limited by the long start-up and acclimation period of processes and microbial communities. To better understand these crucial steps we monitored the microbial community acclimation of four different manures and one digestate to anaerobic digestion at 13°C. The psychrophilic adapted microbial community was then submitted to brutal temperature changes by incubation at 35, 25, 15 and 5°C to assess its adaptive potential. Methane production was measured continuously. Bacterial and Archaeal communities dynamics were monitored by 16S rDNA targeted qPCR, CE-SSCP and pyrosequencin the isolates were identified as Serratia sp. JHT01, Serratia liquefacien PT01, Pseudomonas chlororaphis PT02, Stenotrophomonas sp. PT03 and Mesorhizobium sp. PT04. The Mesorhizobium sp. PT04 was isolated from under water environment. All isolates showed significant growth on water-extractive-free lignin. Synthetic aromatic dyes were used to assess the presence of oxidative enzymes. Pseudomonas chlororaphis PT02 presented high potential in degradation of aromatic monomers and biphenyl. Mesorhizobium sp. PT04 being a facultative anaerobic strain, its degradation of lignin polymer might be executed by specific sets of enzymes. Novel lignin degradation bacterial consortium may be prepared by using these isolates for delignification of the lignocellulosic biomass.

Abstract

International audience; This study investigates the effect of nitrite on the microbial community dynamics during the enrichment of sludge performing anaerobic ammonium oxidation (anammox). Six inoculums were sampled from different environments and enriched under controlled conditions during 4 months. Two different nitrite supply strategies were applied; i.e., (i) low initial concentration at 25 mg NO2--N/L and progressive increase to 150 mg NO2--N/L, and (ii) constant high concentration at 150 mg NO2--N/L. Inoculums only developed anammox activity when working at initial low nitrite concentration. The highest specific anammox activity obtained was 118 mg NH4+-N/g VS/d. No correlation was found between the time of macroscopic evidence of ammonium oxidation and final specific anammox activity. Biomass samples were taken monthly and abundances of both total and anammox bacteria were assessed using quantitative polymerase chain reaction (q-PCR). In addition, 16S rDNA targeted pyrosequencing was used to identify the anammox species enriched and characterize the evolution of the microbial communities during enrichments.

Abstract

In Europe, agriculture is responsible for 10.2% of greenhouse gas (GHG) emissions. The objective of this study was to assess technical measures to reduce GHG emissions at the farm level without reducing production outputs. France was chosen as a case study with a typical intensive and diversified agriculture. Ten measures, split into 26 sub-measures, were selected from an initial list of 100 “candidate” measures. The selection process was based on five criteria: the expected effect on production, the GHG abatement potential, the current availability of the technology required to implement the measure, the applicability of the measure, including its social acceptability, and the potential synergies or antagonisms with other agri-environmental objectives, including adaptation to climate change. The ten selected measures were linked to nitrogen management, management practices which increase carbon storage in soils and biomass, livestock diets and energy production and consumption on farms. Their abatement potential and cost were accurately calculated and compared, using a marginal abatement cost curve approach. Results show that one third of the cumulated abatement potential corresponds to sub-measures with a negative cost. These sub-measures are based on an improved efficiency of inputs like N fertilizers, animal feed and energy, with no negative effect on production. Moreover, no antagonism with the objective of adaptation exists for these sub-measures. Other sub-measures are characterised by a higher cost, because of specific investments, the purchase of specific inputs or dedicated labour time, sometimes partially compensated by additional marketable products (biogas, wood…). Among the 26 sub-measures, only four exhibit a slight antagonism with the objective of adaptation to climate change. When calculated under current inventory rules, the overall annual abatement represents 10% of annual emissions from agriculture. This percentage is higher when calculated using higher tiers. It is concluded that cost-effective technical levers exist for agriculture to support greenhouse gas mitigation without hampering production and adaptation goals.

Abstract

Anaerobic digestion (AD) of organic waste from agriculture and others sectors is a widely used technology which shows increasing implementation due to its capacity to produce renewable energy and also to reduce greenhouse gas emissions from waste management. The development of AD is also an opportunity to improve nutrient recycling from organic waste through the development of an eco-effi cient post-treatment system. In this context,LCA was applied to evaluate the sustainability of diff erent raw digestate post-treatment technologies regarding recycling of nutrients from agricultural and organic waste to agricultural soils for decreased resource depletion and climate mitigation. Substitution of the use of N and P mineral fertilizers with recycled soil health improver or organic fertilizers products as function of fi ve diff erent post-treatment technologies and raw digestate characteristics was evaluated.A particular attention was carried to (1) the gaseous emissions (NH3 and N2O) from process (post-treatment) but also after land spreading and (2) the carbon cycle considering the CO2 carbon costs of fertiliser production and the soil carbon sequestration benefit.

Abstract

International audience; During this study, nuclear magnetic resonance (NMR) was compared to the soxhlet extraction for determination of the lipid content of organic waste usually used in anaerobic digestion. Thus, 48 different wastes were analyzed using both methods and three replicates were performed for each. The correlation between Soxhlet methods and NMR was 0.90 and the regression slope was equal to 1.02. A better precision was obtained for NMR method with a coefficient of variation of 5%, while for the Soxhlet method, this coefficient is 14%. In contrast, the NMR method gave overall values below the reference method soxhlet. This difference can be explained by the advanced state of hydrolysis of fats where a large amount of volatile fatty acids, saturated molecules small chains linked would be present, and the degree of saturation of fatty acids long chains. NMR method seems suited to the analysis of lipids with better repetition and has the advantage of not using any solvent, be fast and non-destructive. However, the determination of some lipid matrices seems undervalued using the conditions established by the NMR protocol. Finally, this study also established data on lipid content of organic waste.

Abstract

International audience; In France, as in several countries worldwide, anaerobic digestion is extensively promoted for the management of organic wastes from various origins like sludge from wastewater treatment plants, food-industry, agriculture (including animal manure and culture residues) and municipal solid waste (including household and green waste). Despite this strong promotion, the status of the digestate remains a problem since it is still considered as a waste by French regulation and can be used only for spreading on land or has to be transformed by composting. Since digestate composition may differ depending on the origin of the methanised substrates and since several different post-processing steps can be used to change its physico-chemical characteristics, we did a review of the different studies realized so far in France concerning anaerobic digestion main waste streams, digestates composition and agronomical value.

Abstract

International audience; This study aims to evaluate the impact of pretreatment on the anaerobic digestion of wheat straw and other lignocellulosic materials. For that, an original procedure named “Anaerobic Respirometry” is used as a tool to monitor the Methane Production Rate (MPR) of treated and untreated materials, allowing determining the impact of pretreatment in terms of CH4 production and degradation kinetics. Results from various grinding technologies, namely impacts mill, knife mill, air-jet mill, ball mill illustrate this procedure. The MPR experimental curves obtained for pretreated substrates show two distinct peaks in the methane production rate. This can result from an accumulation of acetate which is then consumed and gives rise to the second peak. A second hypothesis can also involve a phenomenon of bacteria colonization on the cellulose delaying methane production. Although this double peak complicated the results interpretation, CH4 production over the 10 days period was determined from the MPR in order to evaluate the impact of the mechanical pretreatment on the anaerobic digestion efficiency. The results demonstrate an increase up to 44% in CH4 production from 122 for the knife mill sample up to 175 NLCH4/kgVS for samples grinded by ball mill.

Abstract

International audience; Catch crops cultivated in autumn or over winter can be used as feedstock for agricultural biogas production. Brassicaceae crops are good candidates for this specific use due to their agronomic values in intercropping conditions. However their high content in glucosinolate may conduct to sulphur release in the digesters and induce anaerobic digestion troubles or biogas pollution with hydrogen sulphide. In this study, Brassicaceae crops were used as co-substrate with pig slurry in anaerobic digesters. Their anaerobic biodegradability was close to other lignocellulosic biomass with a large fraction of slowly biodegradable organic matter content. The sulphur and glucosinolates contents in plants did not inhibit the overall anaerobic process neither severely impacted hydrogen sulphide concentration in the biogas.

Abstract

International audience; Implementing an anaerobic digestion (AD) unit on a territory can help meet several needs, since the AD process provides a solution for organic waste treatment, but also for GHG emissions reduction, renewable energy production or nutrient recovery. When environmental balance is set particularly through Life Cycle Assessment (LCA), the assessment should be based on the function fulfilled by the AD system, and the alternatives studied should reflect the actual opportunities of the implementation area. In this context, this study aims to develop a systemic spatial analysis of opportunities to develop biogas systems within any specific territory thanks to Geographic Information Systems (GIS). The production of biowaste, the agricultural practices and the outlets for energy recovery were studied through this framework for two contrasting territories. GIS treatments results showed AD schemes that differed depending on the features of territories. This work is a relevant previous step to LCA of collective AD plants.
