Hygienic engineering has dedicated a lot of time and energy to studying water filtration because how important it is human health. Thorough familiarity with the process essential for design engineer keep up profit from advances in filtering technology equipment as properties raw continue change. Because removes sediment, chemicals, odors, microbes, an integral part purification process. The mos...

An NREL-designed vortex reactor fast pyrolysis process development unit (PDU) has been used to investigate hot gas filtration of biomass pyrolysis vapors. Most of the experimental work employed a conventional baghouse type of filter that used NEXTELTM ceramic cloth filter bags as the filter medium. A series of experimental runs demonstrated that hot gas filtered biocrude oils having less than 1...

A new configuration of the one stage direct filtration process has been investigated by Prof. Fadel (correspondent author) and his team in Mansoura University, Egypt. In this configuration, deep media with fine gravel particles (size 2-4 mm) has been used under low filtration rate (5-8 m/m/hr). For this system a simplified empirical model is proposed to describe the one stage of direct filtrati...

Air filtration has been shown to be efficient in reducing pathogen burden in circulating air. We determined at laboratory scale the retention efficiency of different air filter types either composed of a prefilter (EU class G4) and a secondary fiberglass filter (EU class F9) or consisting of a filter mat (EU class M6 and F8-9). Four filter prototypes were tested for their capability to remove a...

Removal of turbidity, phytoplankton, and zooplankton from ballast water with waste-tire-made crumb rubber filtration was evaluated in this study. The influences of various design, operational, and water quality parameters (filter depth, media size, filtration rate, temperature, turbidity, running time, etc.) on filtration performance were investigated. Statistical approaches were used to develo...

Micropuncture, clearance, immunofluorescence and light microscopy techniques were used to study kidney structure and single nephron function in rats with autologous immune complex nephritis (AICN), a membranous glomerulonephritis developing over 5 to 20 mo, in the more acute and proliferative glomerular basement membrane (GBM) nephritis and in controls. Both models are known to have clinical co...
