Scott Labs stocks depth filter sheets from 55 microns down to .2 micron. Depth filter cartridges are available from .8 microns to greater than 10 microns.

A micrometer (mi?CROM?e?ter) like this can measure distances to accuracies specified in micrometers (MI?cro?me?ters). Here, the accuracy of 0.002 mm is equal to 2 ?m. A micrometer is, of course, one millionth of a meter or a thousandth of a millimeter. The micron, symbol ?, was originally a special name for this distance, but the name and symbol were officially eliminated in 1968, so it's no longer correct to use microns.

A micron (one-millionth of a meter) is a unit used for microscopic measurements. A human hair is approximately 75-microns.

A micrometer, also called a micron, is a millionth of a meter, or a thousandth of a millimeter. As a reference, the diameter of a human hair is about 100 micrometers. Wavelengths of infrared radiation are typically expressed in micrometers.

If you have a very efficient filtration system that can maintain pristine water quality, you can keep more fish.

Any design for gas powered bumper boats should include twice the number of skimmers and double the filtration capacity of a normal swimming pool. Sand filters are used in a redundant configuration to provide the best method of dealing with the oil residue that is inherent with gasoline powered boats. Enzyme compounds such as “Descum” are used to break down the oil and alleviate some of the problem.

There is no published requirement for vehicle filtration. Car and truck owner’s manuals are silent on the issue and you will find very few companies that even credibly discuss filtration efficiency. We believe this demonstrates that most air filters sold today provide adequate levels of filtration. Particularly when compared with the filtration provided by fuel and oil filters. No. The quality of an air filter can only be judged by reviewing all four important characteristics.

A measure of the pore size in the filter media. Expressed as either ‘Nominal’ or ‘Absolute’. Nominal Rating relates to the percentage of particles at a given size that a filter can capture ie. 10 microns at 90% means it will remove 90% of particles 10 microns in size. Absolute refers to the removal of all particles at a given micron size and larger ie. 20 micron absolute means 100% of particles 20 microns or greater will be captured.

UV systems require pre-filtration to maintain effectiveness as sediment and other contaminants in the water can create a "shadow" which prevents the UV rays from reaching and disinfecting the harmful microorganisms.

The best type of filtration is one that is not in the tank. Hang on filters such as the penguin or emperor bio wheel filters. Canister filters are more thorough. We carry Eheim, the best canister filter available. For very large tanks, pleated canisters with pressure pumps are excellent.

The taste of water depends on what's in the water. The eSpring Water Treatment System does not remove sulphur, but it will remove many substances that affect taste, odour, and clarity of water, such as particulates or chlorine.

Perfectly clean oil at any time is an essential requirement to keep your production machines running smoothly. Unfortunately, all hydraulic and lubricating systems in production are continuously subject to dirt build-up. a matter of fact, dirt causes 80% of all oil related malfunctioning and breakdowns Triple R is the only filter system that can remove the 3 main pollutants: sludge, solid particles and water, just using a single filter element. Very simple..

The filtration system is designed to remove visible matter from the water. The filter medium removes hair, dirt, minute skin flakes, metal or calcium precipitates and other visible debris that would otherwise cause the water to be hazy and cloudy.

In most cases, yes. In freshwater bio filtration works so well, and in salt well enough, to justify the claim that biological filtration should be your main type. There is some argument about bio filtration in reef systems, but bio filtration, when used properly, is sufficient to maintain any fish environment. Mechanical and chemical filtration should only be secondary filter types.
