Abstract    In this study, granulated sludge synthesized in a sequence batch reactor (SBR) and then granulated sludge was transferred to continuous feeding and intermittent discharge (CFID) bioreactor. Two independent variables (air flow rate and hydraulic retention time (HRT)) were considered to optimize the process. Subsequently, long term performance (150 days) of the bioreactor was assessed by monitoring nine responses. The process optimization in CFID regime was performed using a central composite face-centered design (CCFD) and analyzed using response surface methodology (RSM). Based on obtained data, the optimum conditions were achieved at HRT of 7-8 h and air flow rate of 2-3.5 L/min. The CFID with granular sludge acted as a high rate bioreactor as the granular sludge could provide high MLSS concentrations (around 10000 mg/L) in a bioreactor.


Keywords    Carbon and Nutrients Removal, Dairy Wastewater, Granular Sludge, Continuous Feeding and Intermittent Discharge Bioreactor



در این مطالعه، لجن گرانول در یک رآکتور سری (SBR) سنتز شده و پس از آن لجن گرانولیت به تغذیه مداوم و تخلیه متناوب (CFID) منتقل می‌شود. دو متغیر مستقل (سرعت جریان هوای و زمان رفع هیدرولیکی) برای بهینه‌سازی این فرایند مورد توجه قرار گرفتند. پس از آن، عملکرد طولانی مدت (150 روز) بیوراکتور توسط نظارت بر 9 پاسخ بررسی شد. بهینه‌سازی فرآیند در رژیم CFID با استفاده از یک مرکز مرکزی مرکب مرکزی (CCFD) انجام شد و با استفاده از روش سطح پاسخ (RSM) مورد تجزیه و تحلیل قرار گرفت. بر اساس داده‌های به دست آمده، شرایط بهینه در HRT 8 تا 8 ساعت و سرعت جریان هوا 3-5-3 لیتر در دقیقه بود. CFID با لجن گرانروی به عنوان یک بیوراکتور با سرعت بالا عمل می‌کند و لجن گرانول می‌تواند غلظت MLSS بالا (حدود 10000 میلی‌گرم در لیتر) در بیوراکتور فراهم کند.
