This study aims to investigated the effect of aeration mode on membrane bioreactors (MBRs) using a self-designed integrated hollow fiber MBR and flat sheet organic for rural greywater treatment. The pollutant removal efficiency, characteristics activated sludge mixed liquor, mechanisms fouling were systematically analyzed under intermittent continuous modes. results indicate that permeability M...

QCD corrections to the gluino induced contribution to b → sγ are shown to be important in order to extract reliable bounds on the off-diagonal elements of the squark mass matrices. Talk presented by Tobias Hurth at the International Euroconference on High Energy Physics (EPS-HEP99), 15-21 July 1999, Tampere, Finland. Indirect Search for Supersymmetry

The aim of this study was to investigate the influence of different parameters on exopolysaccharide (EPS) production from Enterobacter cloacae subsp. dissolvens using seawater as a basal medium. For this purpose, the effect of carbon (sucrose, molasses, paraffin and sunflower oil) and nitrogen sources, NaCl concentration, incubation time, pH as well as seawater dilution or enrichment with disti...

Bacterial extracellular substances (also known as exopolysaccharides, or EPS) may serve as vectors for trophic transfer of metals in benthic systems because these ubiquitous sediment coatings can sorb high concentrations of toxic metals, and because many benthic invertebrates assimilate EPS sediment coatings upon ingestion. We conducted 3 sets of experiments to determine the assimilative bioava...

Although anaerobic membrane bioreactors (AnMBR) are widely used in high-strength wastewater treatment and resource recovery, operational performance fouling control remain critical issues. In this study, the of a high-biomass (18 ≤ MLSS (g/L) 35) submerged bioreactor (HBSAnMBR) was assessed at organic loading rates (OLR) 1.05–5 kg-COD/m3/d to treat abattoir (AWW). The correlation between kineti...

OBJECTIVE To determine the dissolving ability (DA) of linear pentasodium tripolyphosphate (PSTP), cyclic trisodium metaphosphate (TSMP), polymeric sodium metaphosphate (SMP) on synthetic crystals of calcium pyrophosphate dihydrate (CPPD) and on crystalline aggregates of menisci from patients with chondrocalcinosis (CC). METHODS Synthetic CPPD crystals were mixed with phosphate buffered saline...

Vanillin ― a bioactive substance to interfere various biological activities is reportedly able mitigate fouling in membrane bioreactor (MBR). However, impact of continuous dose vanillin on treatment performance and microbial MBR are still unknown. In this study, effects production extracellular polymeric substances (EPS) community was investigated lab-scale under vanillin. remarkably reduced ac...

Biopolymers are considered a potential alternative to conventional chemical polymers because of their ease of biodegradability, high efficiency, non-toxicity and non-secondary pollution. Recently, extracellular polymeric substances (EPS, biopolymers produced by the microorganisms) have been recognised by many researchers as a potential flocculent for their applications in various water, wastewa...
