Article Synopsis
- Sulfamethazine (SMZ), an antibiotic from the sulfonamides class, is commonly found in wastewater, making its removal from the aquatic environment essential.
- The study investigates the use of a horizontal flow-anaerobic immobilized biomass reactor (HAIB) to remove SMZ, evaluating its performance across three concentrations and measuring its removal kinetics.
- Results show that the HAIB reactor achieved SMZ removal efficiencies of 56% to 62%, detected seven transformation products, including one new compound, highlighting its potential for cost-effective wastewater treatment at low contaminant concentrations.
Article Synopsis
- The study evaluated the performance of three carbon materials—carbon felt, carbon cloth, and carbon paper—as anodes in microbial fuel cells (MFCs) for treating winery wastewater.
- The results showed that carbon felt produced the highest voltage (72 mV) and power (420 mW/m), while carbon paper yielded the lowest (0.2 mV and 8.37 mW/m).
- Furthermore, the removal rate of chemical oxygen demand (COD) from the wastewater was highest with carbon felt (650 mg COD/L/day) and lowest with carbon paper (270 mg COD/L/day), indicating that the effectiveness of electricity generation and organic matter removal relates more to the surface characteristics of the electrodes than their chemical composition.
The objective of this paper was to determine the influence of sludge age on microbial fuel cell (MFC) performance for generating electricity and removing organic matter from winery wastewater. Six Solid Retention Times (SRT) were used: 1.2, 1.

Under the 1988 Brazilian constitution all citizens have the right to health care, anticipating the global commitment to Universal Health Care. Brazil's public sector prides itself on having one of the world's largest single payer health care systems, but complementing that is a significant and larger private sector that is seeing big increase in investment, utilization and prices.

The broad 'red component' (2136 cm, 4.681 μm) is generally attributed to solid CO mixed in a hydrogen-bonded environment.
