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.
Filtering of substances is done using different forms of the process. The type of filtering adopted varies depending on where the targeted solid is located. The solid may be present in suspended form or in dissolved form. Desired outcomes also play a role in choosing the kind of filtering to be used. Types of filtering are many, but the common examples are vacuum, cold, and hot filtration.
Hot filtration is used in applications that involve separating hot solutions and solids. Solutions have to be kept hot so as to prevent crystals from forming and sticking on the apparatus. The solution as well as the apparatus used are heated and used while hot. Occurrence of crystallization blocks the funnel preventing the process from continuing.
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.
The last variety called the vacuum filtration is preferred in a very specific application. It is used mainly for small batches of solution to dry out tiny crystals fast. The process employs many pieces of equipment including a rubber tubing, Buchner flask, Buchner funnel, and filter paper. The filter paper usually has a smaller diameter compared to the funnel.
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.
