A nonlinear single-particle model is introduced, which captures the characteristic of systems in the quantum Hall regime. The model entails the magnetic Shrödinger equation with spatially variable magnetic flux density. The distribution of flux is prescribed via the postulates of the mesoscopic mechanics (MeM) introduced in my previous articles [cf. J. Phys. Chem. Solids, 65 (2004), 1507-1515; ...

The nature of solids-liquid flows often results in non-uniform profiles of solids volume fraction and axial solids velocity across the flow cross-section. In order to measure the solids volumetric flow rate in these situations it is necessary to measure the profiles of the local solids volume fraction and axial solids velocity and to obtain mean values of the solids volume fraction, solids axia...

The Curonian Lagoon is a unique system that temporary reservoir of water, accumulating about 62% the suspended solids in river runoff. average activity plutonium particulate matter water Neris River was 0.26±0.02 Bq/kg, and 137Cs ranged from 23±8 to 49±12 Bq/kg. flux dissolved species estimated be (78±61) × 109 Bq/year. Preliminary estimates indicate annual input 239,240Pu Neman into 0.9 GBq, w...

Fouling of membrane surfaces by particulate matter and large organic molecules is relatively common for pressure-driven membrane processes, namely, reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF). Donnan membrane process (DMP) or Donnan Dialysis is driven by electrochemical potential gradient across a semipermeable ion exchange membrane. Theoretically, DMP is not susceptible...

This paper presents Membrane Bioreactor (MBR) and Nanofiltration (NF) systems as alternative effective approaches for treatment reusing domestic sewage. The goal is to investigate the general performance of a membrane bioreactor nanofilteration ability satisfy water reuse requirements using quality index such total suspended solids (TSS), chemical oxygen demand (COD), ammonia (NH3). findings sh...

A pilot-scale submerged membrane bioreactor (MBR) was incorporated in a conventional activated sludge (CAS) process for more than 100 days in order to assess the feasibility and performance on the municipal wastewater treatment. After a stabilization period of 50 days, the MBR unit was operated under various temperatures (21 ± 4°C), mixed liquor suspended solids (MLSS) concentrations (14000 ± 1...

Robust statistical tools were applied on the water quality datasets with the aim of determining the most significance parameters and their contribution towards temporal water quality variation. Surface water samples were collected from four different sampling points during dry and wet seasons and analyzed for their physicochemical constituents. Discriminant analysis (DA) provided better results...

Considerable research is focused on understanding the functionality of starch hydrolysis products (SHP) consisting of glucose, maltose, maltooligosaccharides (MOS), and maltopolysaccharides (MPS). A confounding factor in this research is the high molecular dispersity of commercially available SHP. The study presented herein characterizes a flexible fractionation approach for lowering the disper...

In this paper, a method of Micellar Enhanced Ultrafiltration (MEUF) with Hexadecyltrimethylammonium bromide (CTAB) is proposed to remove phosphate ions from treated domestic wastewaters from the reclamation station of University Campus of Toledo (Spain). This technique is able to reach phosphate rejection coefficients higher than 99% (a phosphate concentration in permeate of 1 mg/L if feed conc...
