Sludge is a by-product of municipal wastewater treatment plants (WWTPs) and its management contributes significantly to the operating costs. Large WWTPs usually have anaerobic sludge digesters valorize as methane reduce mass. However, low market price opens possibility for generating other high value-added products from organic matter in sludge, such polyhydroxyalkanoates (PHAs). In this work, economic feasibility retrofitting two types convert them into biofactories crude PHAs was studied....
Anaerobic digestion is an alternative bioprocess used to treat effluents containing toxic compounds such as phenol and p-cresol. Selection of adequate sludge inoculum adapted microbial consortium a relevant factor improve the removal these pollutants. The objective this study identify key microorganisms involved in anaerobic p-cresol elucidate relevance bamA gene abundance (a marker for aromatic degraders) process, order establish new strategies inocula selection system's performance....
Nitrate, a major groundwater pollutant from anthropogenic activities, poses serious health risks when present in drinking water. Denitrification using bio-electrochemical reactors (BER) offers an innovative technology, eco-friendly solution for nitrate removal groundwater. BER use electroactive bacteria to reduce inorganic compounds like and bicarbonate by transferring electrons directly the cathode. In our work, two batch were implemented at 1V 2V, anaerobic digestate full-scale wastewater...
In Chile, small wastewater treatment plants (WWTPs) (treatment capacity of less than 4,800 m3/d) are normally not designed with consideration for the potential valorization generated sludge. For this reason, they generally operated at high solids residence times (SRT) (15 d) to promote decay biomass, promoting sludge production and reducing costs associated biomass management. Operation SRT implies need a larger activated system, increasing capital costs. The implementation...
Nitrification and sulfur-based autotrophic denitrification processes can be used to remove ammonia from wastewater in an economical way. However, under certain operational conditions, these accumulate intermediate compounds, such as elemental sulphur, nitrite, nitrous oxide, that are noxious for the environment. In order predict generation of analysis based on Gibbs free energy possible reactions oxidative capacity bulk liquid was done case study systems. Results indicate is not a useful...
Here, we report the complete genome sequence of Pseudomonas chilensis strain ABC1, which was isolated from a soil interstitial water sample collected at University Adolfo Ibañez, Valparaiso, Chile. We assembled PacBio reads into single closed contig with 209× mean coverage, yielding 4,035,896-bp 62% GC content and 3,555 predicted genes.
The variability of the fractal dimension value can be used as an indicator stability aerobic granular sludge.
Continuous aerobic granular sludge reactors have potential for retrofitting wastewater treatment plants, enhancing capacities, and reducing footprint. This study investigates the main variables influencing granulation microbial dynamics in two reactor configurations (25 L): stirred tanks series (R1) a plug-flow-like system (R2). Granule formation was achieved by increasing organic loading rate (OLR) from 0.7 to 4.1 kg COD/(m3·d) up-flow velocity biomass selector 1.4 6.9 m/h. However,...
Data in this article provides detailed information on the microbial dynamics and degradation performances two full-scale anaerobic digesters operated parallel for 476 days. One of them was kept at 35 °C whole experiment, while other submitted to sub-mesophilic (25 °C) conditions between days 123 373. Sludge samples were collected from both 0, 80, 177, 218, 281, 353, 462. The provided data include operational characterization sludge physicochemical level, indicative digesters' performance. It...
