چکیده

هدف این پژوهش، ساخت غشای نانوالیافی پلیمری و بهبود ویژگی­ های سطحی آن به منظور کاهش گرفتگی برای استفاده به عنوان غشای ضد گرفتگی میکرو تصفیه پربازده در تصفیه پساب بود. غشاهای نانوالیافی میکرو تصفیه پلی‌آکریل نیتریل اصلاح شده از الکتروریسی محلول های پلی آکریل نیتریل دارای نانوذره­ های بوهمیت با غلظت‌های 5/0 تا w/w 5% تهیه شدند. اصلاح غشا به وسیله­ ی نانوذره­ های آب دوست بوهمیت باعث افزایش آب دوستی سطح غشا و کاهش گرفتگی آن شد. در بین غشاهای ساخته‌شده، غشای نانوالیافی پلی آکریل نیتریل دارای w/w 3% نانوذره­ های بوهمیت به‌عنوان غشای بهینه انتخاب‌شد که دارای ویژگی‌های ضد گرفتگی برتر و شار عبوری بالاتر بود. با توجه به نتیجه­ های به دست آمده، غشای شار بالای ساخته شده که دارای قابلیت گرفتگی پایین بوده می تواند به طور مؤثری در فرایند های گوناگون تصفیه پساب مورد استفاده قرار بگیرد
