Filtration refers to a physical or mechanical technique for separating solids from fluids, gases and liquids. The process entails having a medium interposed so that it allows the fluid to go through while retaining the solid constituent. The liquid which goes through the filter medium is referred to as the filtrate. This method results in incomplete separation since small particles of the solid may pass through the filter medium while fluids contaminate solids.
How completely separation is achieved depends on various factors. The thickness of the filter and size of the pores are some of those factors. The word filter is often used to describe biological processes too. Among biological processes described using this term are treatment of water and sewerage. The undesired materials get absorbed into biological films that grow on or in the filter mediums. There are several corporations engaged in the production of equipment and systems utilized for liquid filtration in Beaumont TX. Both residential and industrial applications can be achieved using the systems.
There are several different methods of filtration all used for separation of substances. The location of target material dictates the type of filtering is used. For example, materials may appear in either dissolved or suspended form. The outcomes that one intends to achieve may also play a role in the choice of method. There are many types, but the main ones are cold, vacuum, and hot filtration.
The hot variety of this method is mostly used for separating solids from hot solutions. The reason for keeping the solution hot is to prevent crystals from forming in the apparatuses used in the process such as filter funnels. Thus, both the apparatuses and the solution may be heated so that the temperature of the solution does not drop drastically to cause crystallization. Crystallization leads to formation of solids in the funnel, preventing further filtering.
The cold variety involves quick formation of crystals by having the solution poured on an ice bath. Ice baths help with the fast formation of crystals of small sizes. If the solution is left to cool at room temperature, the crystals formed would have large sizes.
Vacuum filtration finds use in certain specific applications. It dries out tiny crystals quickly in small portions of solution. Many apparatuses are employed in this process. Some of them are Buchner flasks, rubber tubing, filter papers, and Buchner funnels. Filter papers used have greater diameters than the funnels.
There are two main types of filter media, that is, depth and surface filters. Surface filters are in form of solid sieves which may incorporate filter papers for trapping solid particles. Some main examples include cross-flow filter, screen filter, belt filter, rotary vacuum-drum filter, and Buchner filter. Conversely, depth filters refer to beds composed of granular materials that retain solid particles passing through.
Particles have a greater surface area to be trapped in in depth filters as compared to surface filters. That is why surface filters clog more easily than depth filters. Cleaning of filter medium is done using detergents or solvents. Backwashing process is also used, but in engineering applications such as sewerage treatment applications.
