![]() ![]() As a whole, the effectiveness of MBBR for micropollutant removal was comparable with those of activated sludge processes and MBRs. When it came to sponges moving in natural environments, the most notable previous evidence was that certain types of encrusting sponges are able to remodel their bodies in a sliding fashion as. Particularly, carbamazepine, ketoprofen and pentachlorophenol were found at high concentrations (7.87, 6.05 and 5.55 lg/g, respectively) on suspended biosolids. However, sorption to sludge phase was also a notable removal mechanism of some persistent micropollutants. ![]() In the MBBR system, biodegradation served as a major removal pathway for most compounds. Sponge dissolving weird tessellation looping moving triangles Stock Footage AD ,weirdtessellation. The results for bench-scale sponge-based moving bed bioreactor (MBBR) system elucidated compound-specific variation in removal, ranging from 25.9% (carbamazepine) to 96.8% (b-Estradiol 17-acetate) on average. Acclimatized sponge showed significantly enhanced removal of some less hydrophobic compounds (logD < 2.5), such as ibuprofen, acetaminophen, naproxen, and estriol, as compared with non-acclimatized sponge. Batch experiments demonstrated that micropollutants could adsorb to non-acclimatized sponge cubes to varying extents. This study investigated the removal of micropollutants using polyurethane sponge as attached-growth carrier. ![]()
