In this study, the responses of Dissolved Air Flotation (DAF), sedimentation, and sand filtration treatment processes on feed water with varied algal concentrations were investigated, based a technical–economic analysis using data collected from drinking plant (DWTP) in Guangxi, China. Cost-effective for sources algae proposed. The results showed that DAF was able to achieve almost 95% removal ...

The forward osmosis (FO) process was suggested as a pretreatment to multi-stage flashing (MSF) plant reduce the environmental impact of brine discharge and chemicals used. Yet, there is no study investigating performance FO MSF using tertiary sewage effluent (TSE) feed solution. Combining with TSE generates considerable permeation flux, reducing membrane area capital cost. This evaluated for in...

The paper is devoted to the analysis of the shape of the swash edge line. Formation of the swash boundary is treated as an interfacial phenomenon. The simplest quantitative characteristic of the roughness of interface is its width w, defined as the root-mean-square fluctuation around the average position. For rough interfaces, the scaling with size of the system L is observed in the form w(L)∝ ...

Primary sclerosing cholangitis (PSC) is a chronic, progressive cholestatic disease that is associated with inflammatory bowel disease (IBD) in approximately 70% of cases. Although the pathogenesis is still unknown for both diseases, there is increasing evidence to indicate that they share a common underlying predisposition. Herein, we review the epidemiology, diagnosis, disease pathogenesis, an...

A dead-end filtration model that includes the three main fouling mechanisms mentioned in Hermia (i.e., cake build-up, complete pore blocking, and pore constriction) and that was based on a constant trans-membrane pressure (TMP) operation was extensively modified so it could be used for a sidestream configuration membrane bioreactor (MBR) situation. Modifications and add-ons to this basic model ...

Coliforms were enumerated by using m-Endo agar LES and m-T7 agar in 102 routine samples of drinking water from three New England community water systems to investigate the occurrence and significance of injured coliforms. Samples included water collected immediately after conventional treatment, during the backwash cycle, at various points in the distribution system, and 1 week after the break ...

This paper discusses adsorption of estrone to microfiltration hollow fibre membrane from aqueous phase using estrone as the model compounds. The partitioning of estrone between membrane and aqueous phase at equilibrium state, the concept of membrane retention towards estrone caused by adsorption, adsorption kinetics, and the application potential of membrane adsorption have been assessed throug...
