Existing wastewater treatment technologies face the key challenge of simultaneously removing emerging contaminants and nutrients from efficiently, with a simplified technological process minimized operational costs. In this study, novel alginate-embedded magnetic biochar-anoxygenic photosynthetic bacteria composite microspheres (CA-MBC-PSB microspheres) was prepared for efficient, cost-effective one-step removal antibiotics NH4+-N wastewater. Our results demonstrated that CA-MBC-PSB removed 97.23% sulfadiazine (SDZ) within 7 h 91% 12 h, which were 21.23% 38% higher than those achieved by pure calcium alginate-Rhodopseudomonas palustris (53% 45.7%), respectively. The enhanced SDZ attributed to photoheterotrophic metabolism excretion extracellular photosensitive active substances R. Palustris through photo-bioelectrochemical interaction between biochar. long-term pollutants performance not deteriorated but continuously improved increasing ruse cycles simultaneous efficiency 99% 92% after three cycles. excellent stability reusability due fact alginate acts as an encapsulating agent preventing loss contamination biomass. also exhibited (89% in h) (90.7% secondary effluent plant, indicating stable efficient practical treatment.

Sewage sludge is the main by-product of wastewater treatment plants, requiring significant environmental and economic burdens for its management disposal. Recently, solar drying processes, often performed through greenhouses, received interest due to their limited energy requirement renewable exploitation. The dried shows volume mass reductions, reducing transportation disposal costs. However, physicochemical microbiological characteristics must be properly assessed, especially if agricultural reuse final destination, possible accumulation (micro)pollutants in soil. This review depicts state-of-the-art processes sewage sludge, with a focus on technological aspects quality. discusses greenhouse-specific features, composition (organic matter, pathogens, heavy metals emerging pollutants) conditions (seasonality, ventilation, mixing thickness, speed). connected are presented. limitations this technology discussed as well, including applicability wet issues greenhouse structure degradation. A wider application recommended increase sustainability small medium areas high amounts radiation dry weather conditions, while thermal still appears preferable large plants. More agronomic studies conducted assess pollutant crops, alternative uses (e.g., recovery incineration, pyrolysis or gasification; utilization construction materials) should explored, also using life cycle assessment.

Abstract Emerging contaminants (ECs) are a category of relatively newly identified chemicals lacking regulatory status and generally synthetic origin. ECs encompass range substances, including pharmaceuticals, antibiotics, antidiabetics, pesticides, personal care products (PCPs), endocrine‐disrupting chemicals. frequently found in surface water, groundwater, wastewater. Wastewater treatment plants (WWTPs) often as sources these enter wastewater through improper disposal or usage consumer goods, agricultural runoff, toxic spillage, prescription drug excretion urine feces, the human body metabolizes fraction administered drugs. The presence aquatic environments poses significant threat, they can potentially harm both ecosystem humans, even at low concentrations. For comprehensive understanding impacts ECs, it is essential for researchers to investigate occurrence, sources, fate, transport substances This review investigates origins ultimate fate examining their interactions with surrounding environments. It aims provide characteristics behaviors an in‐depth analysis. discusses techniques processes examines potential pathways future advancement.
