Full textThis work aims at understanding and measuring the bacterial aggregates structure formed during the activated sludge process of domestic wastewater treatment. In order to be able to complete this study, a new theoretical and experimental tools has been developed to extract structural information form aggregated systems. We set up a new method to measure the fractal dimension of aggregates using light scattering techniques. This new method allows as well to determine accurately the granulometric distribution considering fractal geometry of bacterial flocs. 10 activated sludge samples have been studied. We determined their structural (fractals dimensions arise between 2. 09 and 2. 33) and granulometric (large size between 100 and 3000um) characteristics. The floes settling is improved considering large, monodisperse and compact flocs. Iron plays a key role in the flocs settling ability. Calcium and Magnesium form cafcionic bridges in the exopolymers matrix. To optimize settling and biological activity, we study the flocculation of Escherichia coli and decanted raw water by cationic synthetic polymers. We point out the flocculation is very efficient. The biological activity of aggregated systems is identical although the biomass is reduced until 30% using the highly cationic polymers. The flocculation gives rise to aggregates with a reduced number of biological inactive zones. The kinetic flocculation is very fast and gives birtli to monodisperse and large (more than 100 um aggregates. However the modeling of activated sludge flocs by synthetic aggregates issued from the controlled flocculation of decanted raw water is not always satisfying. The discrepancy points out the huge impact of the process condition on the flocculation step in wastewater treatment plant

Full textIn Quebec, wastewaters are mostly treated with aerated facultative lagoons. Since the adoption of the Regulation respecting municipal wastewater treatment works, many municipalities need to upgrade and improve their wastewater treatment station to comply with the new requirements, which are a concentration of suspended solids (SS) less than or equal to 25 mg/L and a concentration of the 5-day carbonaceous biochemical oxygen demand (CBOD5) less than or equal to 25 mg/L. Moreover, many stations have arrived at the end of their operating life expectancy and other stations have even exceeded their organic loads or flowrate loads. One solution that would help these municipalities would be to improve these stations with the new KAMAKMC technology developed by Bionest. This new technology incorporates two reactors containing BIONEST® inert media placed directly in a lagoon, between three clarification zones. At this time, there is a lack of technical data to ensure a good understanding of the KAMAKMC system. The aim of the present study is to characterize sludge accumulations in this new technology, especially in the clarification zones. Tests were conducted with a KAMAKMC system installed in the first third of an aerated lagoon belonging to the municipality of Grandes-Piles, in province of Québec. Between May 2016 and May 2017, measurements of sludge accumulations are taken monthly with a sludge judge in the clarification zones. To compare these measurements, sonar testing is taken 3 times during the year (April and October 2016 and May 2017). Sludge samples are taken during the year to measure total suspended solids (TSS) and volatile suspended solids (VSS). Moreover, gas sampling equipment sits over the lagoon to retrieve samples during the summer months of 2016, to allow a better characterization of anaerobic digestion in the zones. Water temperature during this follow up was between 2°C and 22°C. The sludge accumulation rate in the second and the third clarification zones were 0,05m3y -1hab-1 et de 0,06m3y -1hab-1 . In fact, the first clarification zone had a sludge accumulation rate of 0. This indicates that aeration in the first zone was high, restraining the sludge accumulation to a value of 0,6m and that primary solids were probably displaced in the next two clarification zone due to excessive aeration. The VSS/TSS ratio indicates that in cold temperature, the ratio was constant in every zone, while during the summer months a lower ratio was observed. Values of 18 LCH4m-2d -1 and 4 LCH4m2d -1 in Cl2 and Cl3 were found with the gas collector on the lagoon. Average methane concentrations in the gas collector were 62,8% and 1,4% of CO2. The low percentage of CO2 might be caused by the gas solubilization in the water.

Full textThe objective of this work is firstly, i) to study the microbial behaviour of the biomass especially the production of the EPS in the presence of pharmaceutical compounds (an anticancer product and five antibiotics); and secondly, ii) to study EPS in the context of the sludge settling in wastewater treatment plants. The study in the presence of the anticancer product was done in membrane bioreactors. The presence of the anticancer product provoked the production of the EPS as the protection mechanism which is at the origin of the membrane fouling.The effect of five antibiotics was evaluated in batch reactors. The family of macrolides showed the most important effect on the microbial activity with a significant increase of the EPS production which was associated with a protection mechanism.Sludge settling in the presence of fungi was carried out in a pilot reactor. The spectacularly improvement of the sludge settleability was related with a better cohesion inside of the flocs attributed to an increase of the EPS production.Finally, the diagnosis of different wastewater treatment processes was established in three paper mill wastewater treatment plants thanks to the double approach used here, the physico-chemical analysis of the sludge and the statistical analysis by principal components analysis of the different parameters recorded in each plant. We tried to describe the parameter related to the settling behaviour by linear or polynomial regressions of second degree in function of a reduced number of the measured parameters
