This study demonstrates that microalgae can effectively recover all P and N from anaerobically treated black water (toilet wastewater). Thus, enabling the removal of nutrients generation a valuable algae product in one step. Screening experiments with green cyanobacteria showed tested species successfully grew on water. In subsequent controlled experiment flat-panel photobioreactors, Chlorella sorokiniana was able to remove 100% phosphorus nitrogen medium. Phosphorus depleted within 4 days...
Human activities are pushing earth beyond its natural limits, so recycling nutrients is mandatory. Microalgae highly effective in nutrient recovery and have strong potential as a sustainable wastewater treatment technology. Here, from black water (toilet wastewater) were recovered microalgal biomass, which was dried assessed fertilizer pot experiments compared with inorganic fertilizer. We deciphered the effects of biomass biofertilizer on plant growth quality biological processes linked to...
Photogranules are a novel wastewater treatment technology that can utilize the sun's energy to treat water with lower input and have great potential for nutrient recovery applications. They been proven efficiently remove nitrogen carbon but show conversion rates phosphorus compared established systems, such as aerobic granular sludge. In this study, we successfully introduced polyphosphate accumulating organisms (PAOs) an photogranular culture. We operated photobioreactors in sequencing...
Abstract Photogranules are spherical aggregates formed of complex phototrophic ecosystems with potential for “aeration-free” wastewater treatment. from a sequencing batch reactor were investigated by fluorescence microscopy, 16S/18S rRNA gene amplicon sequencing, microsensors, and stable- radioisotope incubations to determine the granules’ composition, nutrient distribution, light, carbon, nitrogen budgets. The photogranules biologically chemically stratified, filamentous cyanobacteria...
Global surface waters are in a bad ecological and chemical state, which has detrimental effects on entire ecosystems. To prevent further deterioration of ecosystems ecosystem services, it is vital to minimize environmental pollution come up with ways keep water healthy clean. Recently, photogranules have emerged as promising platform for wastewater treatment remove organic matter nutrients reduced or eliminated mechanical aeration, while also facilitating CO
Global stores of important resources such as phosphorus (P) are being rapidly depleted, while the excessive use nutrients has led to enrichment surface waters worldwide. Ideally, would be recovered from wastewater, which will not only prevent eutrophication but also provide access alternative nutrient stores. Current state-of-the-art wastewater treatment technologies effective in removing these yet they can recover P and often an insufficient way. Microalgae, however, effectively assimilate...
Abstract There is growing evidence of negative impacts antidepressants on behavior aquatic non-target organisms. Accurate environmental risk assessment requires an understanding whether with similar modes action have consistent impacts. Here, we tested the effect acute exposure to two antidepressants, fluoxetine and venlafaxine (0–50 µg/L), organism, i.e., freshwater pond snail, Lymnaea stagnalis . As compounds interact chemical cues in ecosystems, also effects altered presence bile extract...
Separation of wastewater streams produced in households according to their origin, degree pollution and affinity a specific treatment constitutes starting point the DESAR concept (decentralised sanitation reuse). Concentrated black water kitchen waste carry highest load organic matter nutrients from all waste(water)streams generated different human activities. Anaerobic digestion concentrated is core technology concept. The applicability UASB septic tank for was investigated under two...
Microalgae-based technologies can be used for the removal of organic micropollutants (OMPs) from different types wastewater. However, effect wastewater characteristics on is still poorly understood. In this study, sixteen OMPs by Chlorella sorokiniana, cultivated in three (anaerobically digested black water (AnBW), municipal (MW), and secondary clarified effluent (SCE)), were assessed. During batch operational mode, eleven removed AnBW MW. When switching to continuous mode (0.8 d HRT), most...
Emerging pollutants, such as pharmaceuticals and microplastics have become a pressing concern due to their widespread presence potential impacts on ecological systems. To assess the ecosystem-level effects of these pollutants within multi-stressor context, we simulated real-world conditions by exposing near-natural multi-trophic aquatic food web gradient environmentally relevant concentrations fluoxetine in large mesocosms over period more than three months. We measured biomass abundance...
Wastewater is considered a renewable resource water and energy. An advantage of decentralized sanitation systems the separation blackwater (BW) stream, contaminated with human pathogens, from remaining household water. However, composition functions microbial community in BW are not known. In this study, we used shotgun metagenomics to assess dynamics structure function throughout new anaerobic digestion system installed at The Netherlands Institute Ecology. Samples influent (BW), primary...
Wastewater characteristics can vary significantly, and in some municipal wastewaters the N:P ratio is as low 5 resulting nitrogen-limiting conditions. In this study, microbial community, function, morphology of photogranules under nitrogen-replete (N+) limiting (N-) conditions was assessed sequencing batch reactors. Photogranules N- condition were nitrogen deprived 2/3 a cycle duration. Surprisingly, limitation had no adverse effect on biomass productivity. Moreover, phosphorus chemical...
Single microalgae species are effective at the removal of various organic micropollutants (OMPs), however increased diversity might enhance this removal. Sixteen OMPs were added to 2 continuous photobioreactors, one inoculated with Chlorella sorokiniana and other a microalgal-bacterial community, for 112 d under natural light. Three media sequentially used in 3 Periods: I) synthetic sewage (d 0-28), II) 10x diluted anaerobically digested black water (AnBW) 28-94) III) 5x AnBW 94-112). Twelve...
