thus permitting higher filtration rates. Sand-bed filters are operated under pressure in closedvesselsto give high-capacity service. Pressure filters are routinely used in daily life, such as in a vacuum cleaner with a dust bag or paper filter or an automobile engine with an oil filter cartridge...
Filters in Use:Filtration Examples: Some of the most common filter aids used were silica, diatomaceous earth, cellulose, and perlite. They can be used alone or with paper filters. A very simple and proven example of filtration is that if we have sand, salt, and water in a beaker, then ...
See More Examples Scientific definitions for filtration filtration [ fĭl-trā′shən ] The act or process of filtering, especially the process of passing a liquid or gas, such as air, through a filter in order to remove solid particles. The American Heritage® Science Dictionary ...
These include sifting, straining to remove suspended particles such as wastes, uneaten food, algae. Mechanical filters employ media of a small mesh size that restricts these materials passage. Some examples of these filters and media are box filters and their (Dacron) wool, canister filters and ...
In liquid filtration, such as that applied in sewage treatment, a liquid can be pulled through the filter by gravitational force, as in the examples given. On the other hand, some sort of applied pressure, or a pressure differential created by the existence of a vacuum, can force the...
There are several commercial processes that provide the alternating anaerobic and aerobic conditions necessary for enhanced phosphorus uptake. Examples of these are the A/O process, the Phostrip process, and others using a SBR. The A/O process is mainstream removal, while the Phostrip process uses...
Examples of these processes include oil and grease separation, sedimentation, sludge filtering, and membrane filtration. In some cases, what was previously considered a waste stream has become a revenue stream. For example, the dairy industry’s whey disposal problem has been eased thanks to ...
and the second is to filter out only specific materials. The first method is usually inefficient because a ton of energy is needed to filter all materials out and then add certain ions and minerals back in. One of the most famous examples of this is desalination, the process of removing sa...
Below are a few examples of the many applications for wedge-shaped wire. A screen filter is a technical device for mechanically freeing liquids from suspended solid materials. Screen filters are advantageous compared to other techniques because they require no consumables. They can be cleaned by rev...
Examples of pelletized spawn range from a form resembling rabbit food to pumice-like particles. Idealized pelletized spawn seeks a balance between surface area, nutritional content, and gas exchange and enables easy dispersal of mycelium throughout the substrate, quick recovery from the concussion of...
