the excessive biological sludge production is one of the disadvantages of aerobic process such as sbr. so the problem of excess sludge production along with its treatment , and disposal in aerobic processes in municipal and industrial waste water can be seen in many parts of the world even in our country . to solve the problem of excess sludge production , reducing in by oxidizing some of the s...

This study consolidates Multi-Level Starlet Segmentation (MLSS) and Multi-Level Starlet Optimal Segmentation (MLSOS), techniques for photomicrograph segmentation that use starlet wavelet detail levels to separate areas of interest in an input image. Several segmentation levels can be obtained using Multi-Level Starlet Segmentation; after that, Matthews correlation coefficient (MCC) is used to c...

The results of experiments on municipal wastewater primary effluent are presented for a pilot-scale submerged membrane bioreactor (SMBR). The SMBR pilot plant employed an ultrafiltration membrane with a nominal pore size of 0.035 microm and was operated at a constant membrane flux of 30 L/m(2)h. The mixed liquor suspended solids (MLSS) concentration was maintained at 8+/-2 g/L and steady-state ...

Abstract Aerobic granular sludge (AGS) is known as excellent biological treatment for wastewater industry, high organic load and adsorption of heavy metal. AGS have some advantages such higher density, biomass retention, simultaneous nutrient removal tolerance to toxicity. The aim this research use sequencing batch reactor (SBR) cultivate in the short time (28 days) laboratory scale. Experiment...

In this paper, we propose a new framework for security risk assessment. To conduct analysis efficiently, it is necessary developers to assess the risks of machine learning based system (MLS) by themselves, but existing technologies cannot be used such purpose. Using proposed framework, MLS can MLSs themselves. Our consists two phases. preparation phase, expert extracts conditions adversarial at...

Nine lab-scale continuous flow porous-pot bioreactors operating at various solids retention times and hydraulic retention times were conducted to simulate activated sludge (AS) systems and to evaluate the biodegradation kinetic models for the fate of 17α-ethinylestradiol (EE2), bisphenol-A (BPA), and triclosan (TCS) at the µg/L range. Mathematical models were applied to describe the degradation...

This study focuses on comparing the performance of submerged membrane bioreactor (SMBR) and submerged membrane adsorption bioreactor (SMABR) over a period of 20 days at a hydraulic retention time (HRT) of 3.1h. The effects of PAC on critical flux and membrane fouling were also investigated. The SMABR exhibited better results in terms of mixed liquor suspended solids (MLSS) growth, DOC removal (...
