A mathematical model is derived to simulate the performance of spiral wound membrane modules for the pervaporative separation of binary liquid mixtures. Permeation through the polymer membrane is described by a detailed solution–diffusion model. Flory–Huggins theory is used to predict solubility of the penetrants, while the composition and temperature dependence of the diffusion coefficients ar...

Osmotic backwash experiments were conducted and analytical model was developed in attempt to describe the backwash mechanism. A single unit of a spiral wound RO membrane was used in the experiments. The RO membrane was fed by salted water solution. Permeate flux characteristics of the membrane were determined through steadystate RO experiments. Then the system was shiRed immediately to a backwa...

The conversion of saltwater and brackish water into fresh through desalination has gained significant importance as a solution to the worldwide scarcity resources. Reverse Osmosis (RO) method been effectively utilized generate from sources water. This research aims examine variables that affect performance reverse osmosis process. effectiveness membrane was assessed experiments explored impact ...

A major goal of cancer research is to match specific therapies to molecular targets in cancer. Genome-scale expression profiling has identified new subtypes of cancer based on consistent patterns of variation in gene expression, leading to improved prognostic predictions. However, how these new genetic subtypes of cancers should be treated is unknown. Here, we show that a gene module map can gu...

Modern sealing components are used in a wide range of industrial processes. The recent global attention for reducing emission environmentally harmful substances motivates gasket manufacturers to quantify the performance gaskets. We investigate use fiber Bragg grating sensors measuring seating stress on spiral wound gasket. fiber-optic integrated gasket, following particular instrumentation stra...

BACKGROUND The separation performance of seven polymer membranes for the nanofiltration of sodium lactate in fermentation broth was investigated. Each module was introduced into the test stand, and the system curve was obtained by recording the permeate flow velocity at different pump head levels. Performance benchmarks were good permeate quality, as determined by high permeate flow velocity, h...
