Design of a Model Filtration System and Performing CFD/ Floxpress Analysis on It (original) (raw)

With regard to earlier experiment conducted to determine the characteristics of diluted waste water, a confirmation was obtained experienced by the levels shown using the litmus paper. This then provided a basis for the design of the filtration system which was simulated to ascertain its suitability. This can be said by " drink a minimum of two litres or eight glasses of 8 liquid ounces daily " is a statement with which we are all familiar; it is the recommendation by the UK Food Standard Agency (FSA), corroborated by the US-EPA (UKFSA 2002, & USEPA, 1945). In the high-pressure pipeline, the water energy may dissipate after flowing through the channels and the flow rate can be controlled to meet the water need of the life. To ensure the emitter's hydraulic performance, before the fabrication of emitter, computational fluid dynamics (CFD) is used to predict emitter's flow rate and analyze its hydraulic performance under various water pressures. The quality of the emitter has an important effect on the reliability, life span of the drip irrigation system and irrigation quality. Usually, the structure of the emitter channel is very complex with a dimension. A CFD/FloXpress analysis was carried out to determine the suitability of the filtration system while analysis of filtered water also confirmed that, production of the filters could help in enhancing the purification of the diluted Chemu lagoon and similar water system(Ing. Govi and Gablah, 2015). 1.0 Introduction However in Ghana, water is becoming more and more a scarce and valuable resource as population and consumption rise. Evaluation of these factors, as well as technology and action to support healthy water supplies, is necessary to gain control of the situation. Agricultural use of water accounts for nearly 70 % of the water used throughout the world, and the majority of this water is used for irrigation. A successful uniform application through drip irrigation system depends on the physical and hydraulic characteristics of the drip tubing (Al-Amoud, 1995). In surface drip irrigation systems, uniformity can be evaluated by direct measurement of emitter flow rates. The emission uniformity (EU) criterion is used largely to design micro irrigation laterals and large at CFD/FloXpress. The EU is affected by the variation of pressure head due to elevation changes and head losses along the lines, as well as by water temperature, manufacture's variation, grouping of emitters, clogging, variability in soil hydraulic characteristics, and emitter spacing (Wu, 1997). 1.1 Filtration System Images from the FloXpress/ CFD simulation of the designed filter are discussed in terms of velocity, pressure and discharge. The CFD/FloXpress discusses only the design, the suitability of which will affect the functionality of the elements when they are placed in the vessel. The pollutant concentration levels have been proven to be effectively dissolved/ removed by the use of the media chosen which were mainly obtained from natural sources than synthetic so that it becomes sustainable. 1.2 CFD Design An air filter is generally a paper-like or fibrous material, folded accordion-style and arranged on a plastic or metal frame to fit your car's air filter holder. In an air filtration system, the air must pass through some sort of filter which traps impurities in the air. The design of the filter determines which impurities will be trapped. Most fuel injected vehicles use a pleated paper filter element in the form of a flat panel. This filter is usually placed inside a plastic box connected to the throttle body with an intake tube. Pleated paper filter elements are the nearly exclusive choice for automobile engine air cleaners, because they are efficient, easy to service, and cost-effective. A paper for air filters needs to be very porous and have a weight of 100-200 g/m 2. Normally long fibrous pulp is used to get these properties. The paper is normally impregnated to improve the resistance to moisture. Computational Fluid Dynamics (CFD) is considered to be the most cost effective solution for flow analysis of intake system along with filter media.
