At this article will be created a software written in visual basic for efficiency and penetration calculation in a fibrous filter medium for given values of particles diameter that are retained in the filter. Initially, will become report of mathematical models of air filtration in fibrous filters media and then will develop the code and the graphical interface of application, that are the base...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
Background and Objective:Pulse jet systems are of interest due to their high filtration velocity,They're used as inlets from top and bottom. the purpose of this study was to compare the pressure drop and collection efficiency at the different inlet positions in a baghouse Methods and Materials:In this experimental study, a pilot system was designed at 12ft/min permeability for MDF particles.Fo...
Background and purpose: Today, due to the reduction of water resources, separation of gray water from domestic wastewater and its reuse has gained more interest. The aim of this study was to apply multi-layer filtration (MLF) for removal of nutrients from gray water. Materials and methods: This laboratory-scale study was carried out in 2.3-19.2 gr. COD / L. d organic loading rates (OLR) over a...
A large number of application cases show that air filter media are easy to fail under extreme conditions high humidity, haze, rain and snow, thus seriously affecting the energy efficiency gas turbines. To study impact humidity on dust-holding performance media, three typical applied for turbines with a similar selected, their is investigated at 30%, 60% 75%, respectively. The results showed pre...
abstract background: the aim of this study was to compare the efficiency of conventional slow sand filter with modified filter bed with crushed recycled glass in removing of turbidity and total and fecal coliforms from water resources. methods: in this study efficiency of conventional slow sand filter and modified filter bed with crushed recycled glass during 4 months was compared and their p...
The effects of captopril on effective renal plasma flow and glomerular filtration rate were studied using a noninvasive radioisotopic method on individual kidneys in eight patients with renovascular hypertension and 12 patients with essential hypertension with various renin levels. Four patients with renovascular hypertension had unilateral while three had bilateral renal artery stenosis. The e...
This paper predicts the reductions in the indoor mass concentrations of particles attainable from use of filters in building supply airstreams and also from use of stand-alone fan-filter units. Filters with a wide efficiency range are considered. Predicted concentration reductions are provided for indoor-generated particles containing dust-mite and cat allergen, for environmental tobacco smoke ...
Short-term effects of chlorthalidone are unknown in low kidney function. The effects of 8-week treatment with 25-mg chlorthalidone on the top of ongoing treatment were compared between control hypertensives and low kidney function hypertensives as assessed by estimated glomerular filtration rate <60 mL/min×1.73 m(2). Screening period consisted of 2 visits for patient selection and pretreatment ...
