The presence of contaminants emerging concern (CECs) in agricultural and fisheries water has raised significant environmental health concerns. Vacuum membrane distillation (VMD) shown promise as an effective method for removing non-volatile contaminants, such CECs, from water. This study presents a novel application bench-scale VMD unit to treat Lagoa da Conceição, Florianópolis, Brazil, using microporous membranes (0.22 µm) under the following optimized conditions: 75 °C, flow rate 24 L·h−1, vacuum pressure −640 mmHg. system demonstrated remarkable performance several key antimicrobials, including sulfamethoxazole, ciprofloxacin, azithromycin, clindamycin (500 μg·L−1), with rejection rates 99.1%, 98%, 99.9%, 99%, respectively, average flux 7.08 L·m−2·h−1. Additionally, achieved substantial 99.98% salt rejection. Ecotoxicity tests revealed low toxicity azithromycin but high clindamycin, while human risk assessment indicated moderate-to-high risks ciprofloxacin clindamycin. findings highlight potential sustainable technology removal CECs biocompounds, enhancing safety reducing hazards. offers promising solution addressing contamination on broader scale.
