Phenol is a common wastewater contaminant from various industrial processes, including petrochemical refineries and chemical compounds production. Due to its toxicity to microbial activity, it can affect the efficiency of biological wastewater treatment processes. In this study, the efficiency of an Anaerobic Sequencing Batch Reactor (ASBR) fed with increasing phenol concentrations (from 120 to...
مقدمه و هدف: 2، 3، 7، 8 -تترا کلرو دی بنزو- پی- دیوکسین (tcdd یا tetra chlorine dibenzo-p-dioxin) به عنوان سمی ترین ترکیب شناخته شده است که به دلیل سمیت زیاد، پایداری و مقاومت بالایی که در محیط دارد، از اهمیت بالایی برخوردار می باشد. از این رو هدف از انجام این مطالعه بررسی تجزیه بیولوژیکی دیوکسین tcdd در رآکتور asbr (anaerobic sequencing batch reactor) است. روش بررسی: این مطالعه با استفاده از ی...
The performance of a bench-scale integrated swine wastewater treatment system was evaluated on the basis of energy recovery, fertilizer production, and water reclamation. The system consisted of one anaerobic sequencing batch reactor (ASBR), one or two aerobic sequencing batch reactors (SBR1 and SBR2), one sludge settling tank, one sand filter, and one reverse osmosis (RO) unit. The system was ...
Route-Reflection and confederations were introduced to alleviate the scalability issue of maintaining a full-mesh of iBGP sessions. However, these techniques may lead to routing, forwarding, route diversity and sub-optimal routing issues. In this paper, we propose a new scalable internal BGP route distribution architecture that is rid of these issues. We propose an iBGP route distribution archi...
The Border Gateway Protocol (BGP) is heavily used in Service Provider networks for both Internet and BGP/MPLS VPN services. For resiliency purposes, redundant routers and BGP sessions can be deployed to reduce the consequences of an Autonomous System Border Router (ASBR) or BGP session breakdown on customers’ or peers’ traffic. However, simply taking down or even bringing up a BGP session for m...
A global phase 3 study evaluated the pharmacokinetics, efficacy, and safety of recombinant fusion protein linking coagulation factor IX with albumin (rIX-FP) in 63 previously treated male patients (12-61 years) with severe hemophilia B (factor IX [FIX] activity ≤2%). The study included 2 groups: group 1 patients received routine prophylaxis once every 7 days for 26 weeks, followed by either 7-,...
A novel anaerobic treatment system, the anaerobic migrating blanket reactor (AMBR), was developed after completing a parallel study with upflow anaerobic sludge blanket (UASB) and anaerobic sequencing batch reactor (ASBR) processes. Using sucrose as the main component of a synthetic wastewater, the AMBR achieved a maximum chemical oxygen demand (COD) loading rate of 30 g.l .day 1 at a 12-h hydr...
