摘要: Abstract In the paper, fouling behavior of a synthetic secondary effluent was explored and influences membrane operation pressures (25, 30, 50, 75 kPa) on rejection five endocrine disrupting chemicals (EDCs) (estrone, 17β-estradiol, estriol, 17α-ethynyl estradiol, bisphenol A) were during filtration process using 100 kDa polyvinylidene fluoride (PVDF) ultrafiltration (UF) under constant pressure dead-end system. Fouling humic compounds found to obey rule cake filtration. Fouled UF revealed enhanced EDCs removal rate by 0.0% 58.3% corresponding different EDCs. Cakes grew various had specific resistances porosities. Cake formed 50 kPa lowest porosity 56.8% but best efficiency, which may be attributed adsorption size exclusion. Besides, penetration abilities through fouled with E3 being most easy flow out. It can concluded that suitable for aiming at appropriate flux.
