filtering material

The oysters, along with clams also put in the cages, nourish themselves by filtering material out of the water.

The use of a metal screen or some suitable filtering material can also be added to achieve better solids dryness.

A new filtering material has been tested for its biofiltration performance for the treatment of air contaminated with the three isomers of xylene.

The pump should only be powerful enough to push the water through the filtering material as well as overcome the drag in the intake and return pipes.

Over his nose and mouth he wore one of the Authority's gas masks, a transparent sheet of plastic-like filtering material no heavier than a pocket handkerchief.

In one, the Pall Corporation successfuly accused Micron Separation of infringing its patent for nylon filtering material.

So, the air is drawn from outside of the detector through an "infinite" (cycling) ribbon made from some filtering material so that the particles are collected on it.

The aliens themselves were shorter than men, and their helmet openings were coated with a filtering material to cut off visible and ultraviolet rays which to them would be lethal.

Health wise, there is a low risk of germ or bacterial growth inside the machine as the filtering material remains "under water" during its working life providing perpetually freshly filtered water.

"The filtering material - a top wartime secret - represented the greatest scientific advance ever made in cleansing air of impurities," stated one of the advertisements, prepared by Young & Rubicam.

European standard EN 149 defines the following classes of "filtering half masks" (also called "filtering face pieces"), that is respirators that are entirely or substantially constructed of filtering material:

Agitation, heat, special baffling, coalescing packs, and filtering materials can assist in the removal of nonsolution gas that otherwise may be retained in the oil because of the viscosity and surface tension of the oil.

If you try looking through the eyepiece of binoculars or a telescope while wearing these glasses, the concentrated heat from the sun will almost certainly melt a hole through the filtering material, allowing a sudden burst of dazzling sunlight to reach your eye.

Prevention and capture of any gases naturally occurring (volatile organic compounds) during the hot aerobic composting involved is the objective of the biofilter, and as the filtering material saturates over time, it can be used in the composting process and replaced with fresh material.

PenTile RGBW technology, used in LCD, adds an extra subpixel to the traditional red, green and blue subpixels that is a clear area without color filtering material and with the only purpose of letting backlight come through, hence W for white.

The tests conducted in this study have made it possible to propose a rapid and simple laboratory method for determining the appropriate dosages of chemicals according to filtering materials effective sizes (ES), for direct filtration applications, and for adjusting the dosages according to raw water quality changes.
