Due to the importance of quality of drinking water, in this study, cyclodextrin (CDs), polyether block amide (PEBA) and PEBA/CDs polymeric fibrous membranes were synthesized by cost-effective, environmentally friendly and effective electrospinning method. Different techniques such as Fourier transform infrared spectroscopy, X-ray diffraction patterns, scanning electron microscopy and nitrogen adsorption/desorption technique were used to characterize the physicochemical properties of the membrane samples. Uniform morphology, mesoporous diameter and high surface area (453 m2/g) showed that PEBA/CDs polymer nanofibrous membrane can be used as a new candidate to remove taste and smell from drinking water. The effect of contact time, volume of water and nanomembranes dosage on the removal of Navicula algal was investigated. The highest inactivation efficiency of Navicula algal at 70 mL water was achieved under 7 min contact time when 0.3 mg of nanomembranes was used. The results showed that the nanomembranes developed in this study can be reduced the number of algal colonies by five colonies, which is significant compared to previous studies. It seems that the use of new nanostructures as well as the synthesis method developed in this study has a great effect on the performance of these samples to reduce the number of Navicula-colonies and anti-algal effects.
