a lab-scale cross flow membrane bioreactor (cf-mbr) was operated to determine the biokinetic coefficients under mlss concentrations of 5000 and 3000 mg/l. the investigation showed that the yield (y), the endogenous decay coefficient (kd), the maximum specific growth rate (μm) and the saturation constant (ks) were 0.276 mg/mg, 0.07 /day, 0.653 /day, and 396.62 mg cod/l respectively for mlss 5000...

the present work studied the application of membrane bioreactor (mbr) for tapioca wastewater processing that contained chemical oxygen demand (cod) ranging from 4000-9000 mg/l. a preliminary study was initially conducted in order to evaluate membrane performance with respect to its flux with mlss concentration ranging from 4,500 to 10,500 mg/l. it was clear that fouling was observed during the ...

Waste activated sludge (WAS) treatment has gained growing interests for its increasingly capacity and high process cost. Sludge thickening is generally the first of WAS treatment. However, traditional approach was restrained by large footprint, low efficiency, tendency releasing phosphorus. Here, we reported a novel microfiltration (MF) membrane assisting forward osmosis (FO) (MF-FO) thickening...

The objective of this paper is simultaneous of aerobic and anaerobic process for phosphorus removal from a dairy wastewater. The system consists of a granular sequencing batch reactor (SBR) working under alternating aerobic/anaerobic conditions. In order to analyze the process, four significant variables viz. MLSS, COD/N ratio, aeration time and cycling time and four dependent parameters as the...

This submission to the MIREX 2015 Music Structural Segmentation task employs a Convolutional Neural Network (CNN) to identify boundaries within a piece of digital audio. The network was trained on a combination of mel-scaled log-magnitude spectrograms (MLSs) and selfsimilarity lag matrices (SSLMs) with two-level human structural annotations following the SALAMI guidelines. It is based on our wo...

A new hybrid membrane-aerated biofilm reactor (MABR) technology that enables energy-neutral treatment of municipal wastewater is introduced. The process, which removes nitrogen using conventional nitrificationdenitrification, was demonstrated at pilot-scale, treating primary effluent. The new MABR membrane product can operate in a high mixed liquor suspended solids (MLSS) environment, making it...

BACKGROUND The authors sought to demonstrate the safety and effectiveness of the multilevel stabilization screw (MLSS) technique in decreasing the incidence of proximal junctional failure in long segmental instrumented fusions for adult degenerative scoliosis. METHODS Institutional review board approval was obtained and all patients with adult spinal deformity who underwent the MLSS technique...

In this paper we present a fast tableau saturation strategy which can be used as an optimized decision procedure for some fragments of set theory. Such a strategy is based on the use of a model checking technique which guides the saturation process. As a result, it turns out that the saturation process converges much faster than previous decision algorithms either to a closed tableau or to a mo...
