“…65,71 The chlorinated flame retardants TCEP, TCPP, and TDCP are recalcitrant in the aqueous environment 72,73 and resistant to biological degradation in municipal wastewater treatment plants. 58 Bisphenol A, a plasticizer, is highly biodegradable in municipal wastewater treatment plants; 74,75 however, removal and rejection results for bisphenol A can be skewed for experiments conducted with plastic appurtenances because this compound will leach from these appurtenances during operation and testing. 76,77 Twelve TOrCs were highly degraded in the bioreactors: four (acetaminophen, caffeine, ibuprofen, propylparaben) are considered to be highly degradable, 65,78 five (naproxen, diphenhydramine, atenolol, oxybenzone, triclocarban) reported to be moderately degradable, 64,65,78,79 and three (acesulfame, DEET, trimethoprim) would have low removal expectancies in municipal wastewater treatment systems.…”

A hybrid ultrafiltration-osmotic membrane bioreactor (UFO-MBR) was investigated for over 35 days for nutrient and trace organic chemical (TOrC) removal from municipal wastewater. The UFO-MBR system uses both ultrafiltration (UF) and forward osmosis (FO) membranes in parallel to simultaneously extract clean water from an activated sludge reactor for nonpotable (or environmental discharge) and potable reuse, respectively. In the FO stream, water is drawn by osmosis from activated sludge through an FO membrane into a draw solution (DS), which becomes diluted during the process. A reverse osmosis (RO) system is then used to reconcentrate the diluted DS and produce clean water suitable for direct potable reuse. The UF membrane extracts water, dissolved salts, and some nutrients from the system to prevent their accumulation in the activated sludge of the osmotic MBR. The UF permeate can be used for nonpotable reuse purposes (e.g., irrigation and toilet flushing). Results from UFO-MBR investigation illustrated that the chemical oxygen demand, total nitrogen, and total phosphorus removals were greater than 99%, 82%, and 99%, respectively. Twenty TOrCs were detected in the municipal wastewater that was used as feed to the UFO-MBR system. Among these 20 TOrCs, 15 were removed by the hybrid UFO-MBR system to below the detection limit. High FO membrane rejection was observed for all ionic and nonionic hydrophilic TOrCs and lower rejection was observed for nonionic hydrophobic TOrCs. With the exceptions of bisphenol A and DEET, all TOrCs that were detected in the DS were well rejected by the RO membrane. Overall, the UFO-MBR can operate sustainably and has the potential to be utilized for direct potable reuse applications.

“…Meanwhile, the worldwide demand and annual consumption of BPA is also increasing. BPA enters the environment mainly from the permitted discharges of industrial wastewater treatment plants (WWTPs), leachates of waste plastic in landfills, processing of BPA in manufacture, combustion of computer printed circuit boards in electronic waste, and spraying of paint (Peltonen and Pukkila 1988;Staples et al 1998;Furhacker et al 2000;Yamamoto et al 2001;Cousins et al 2002;Owens Jr. et al 2007;Fu and Kawamura 2010;Huang et al 2012). BPA discharged into water system counted for about 92 % of its total emissions (European Commission 2003).…”

Bisphenol A (BPA) is an important monomer in the manufacture of polycarbonate plastics, food cans, and other daily used chemicals. Daily and worldwide usage of BPA and BPA-contained products led to its ubiquitous distribution in water, sediment/soil, and atmosphere. Moreover, BPA has been identified as an environmental endocrine disruptor for its estrogenic and genotoxic activity. Thus, BPA contamination in the environment is an increasingly worldwide concern, and methods to efficiently remove BPA from the environment are urgently recommended. Although many factors affect the fate of BPA in the environment, BPA degradation is mainly depended on the metabolism of bacteria. Many BPA-degrading bacteria have been identified from water, sediment/soil, and wastewater treatment plants. Metabolic pathways of BPA degradation in specific bacterial strains were proposed, based on the metabolic intermediates detected during the degradation process. In this review, the BPA-degrading bacteria were summarized, and the (proposed) BPA degradation pathway mediated by bacteria were referred.

“…Because of its large-scale production and extensive application, BPA has been found ubiquitously in the environment [7]. Many ecosystems, including surface, river, waste, and drinking waters, have been polluted with BPA [1,8,9]. It has been reported that the concentration of BPA in hazardous waste landfill leachates is 17.2 mg/L [10].…”

Abstract-Bisphenol A (BPA) is an environmental endocrine disruptor that seriously threatens ecological systems. Plants are the primary producers in ecological systems, but little information is available concerning the toxic effect of BPA on plants. In the present study, the effects of BPA on the growth and nitrogen nutrition of roots of soybean seedlings were investigated by using a root automatic scan apparatus and biochemical methods. It was found that when soybean seedlings were treated with 1.5 mg/L BPA, the growth of roots was improved, the content of nitrate in roots was increased, the content of ammonium in roots was decreased, and the activities of nitrate reductase and nitrite reductase in roots were not changed. The opposite effects were observed in roots treated with 17.2 mg/L and 50.0 mg/L BPA, except for an increase in the content of nitrate in roots treated with 17.2 mg/L BPA and a decrease in the activities of nitrate reductase and nitrite reductase in roots of soybeans seedlings. Statistical analysis indicated that the change in the nitrogen nutrition of roots of soybean seedlings treated with BPA was one reason why the growth of roots was changed. The authors suggest that the potential environmental and ecological risk of BPA to plants should receive more consideration. Environ. Toxicol. Chem.
