Abstract    The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF) membrane process is used to treat the industrial effluent in which the coagulation is conducted prior to NF process. The effects of several variables during coagulation process, i.e., alum concentration, decolouring polymer dosage, cationic polymer dosage and pH on the colour removal and sludge volume production are investigated using response surface methodology (RSM). Optimum variable conditions are chosen to prepare samples with maximum colour rejection and minimum sludge volume for further treatment using the NF membrane process. Under the optimum coagulation conditions (50 mg/L alum, 441 mg/L decolouring polymer, 534 mg/L cationic polymer and pH 9.2), the results showed 92% colour removal with sludge volume as low as 4.1 mL. Further treatment using commercial NF membranes indicated that a permeate sample with complete elimination of colour (almost 100% colour removal) could be produced with reasonably high water flux.

حضور لیگنین (Lignin) و محصولات حاصل از تجزیه آن نظیر تنین (Tannin) و اسیدهای هیومیک (Humic acids) دلیل اصلی رنگ نشان دادنAT-POME در نقطه تخلیه می باشد. در این کار از یک روش ترکیبی برای تجزیه کردن نمونه ی AT-POME که به صورت معمولی با استفاده از روش بیولوژیکی تجزیه شده بود بهره گرفته شد. این روش ترکیبی که که انعقاد و غشای نانوفیلتر در آن به کار گرفته می شوند برای تصفیه کردن پسابهای صنعتی استفاده می‌شود. در روش ارائه شده فرایند انعقاد پیش از نانوفیلتر کردن انجام می‌شود. به منظور یافتن شرایط بهینه برای فرایندنانوفیلتر کردنتاثیر چندین متغیر از جمله غلظت آلوم (Alum)، غلظت پلیمر رنگزدا، غلظت پلیمر کاتیونی و نیز pH بر رنگزدایی و حجم لجن تولید شده در طول فرایند انعقاد بررسی شد. در شرایط بهینه ی انعقاد (غلظت آلوم mg/L50، پلیمر رنگزدا mg/L 441، پلیمر کاتیونی mg/L 534 و pH 2/9) نتایج حاکی از 92% رنگزدایی با حجم لجن 4.1 میلی لیتر بود. تصفیه‌ی بیشتر با استفاده از غشاهای تولید شده به صورت تجاری نشان داد که یک نمونه شفاف با رنگزدایی کامل ( نزدیک به 100%) با دبی نسبتا بالای آب قابل دستیابی است.
