Pumice as a Filtration Media Pumice is, at its essence, foamed glass, formed by the expansion of trapped gases when molten lava rapidly cools. When crushed, pumice still retains its frothy structure, making it eective at any ltration grade. As a ltration media, pumice is an aggressively-ltering alternative to sand and other

Aquarium Sand amp Gravel. Red Flint Aquarium Sand amp Gravel are key material components in large aquariums and zoos throughout North America and Globally. The unique physical properties of Red Flint products include very low acid solubility and naturally clean particles create the perfect solution to your substrate and filtration needs.
Sand. Silica sand is the oldest of the filtering medias. Not all sand is created equal and if you are going to replace your old media with sand, silica sand is the way you need to go. Number 20 silica sand will filter down to 20 microns. As you can see from our chart above it will take care of most suspended solids in the pool water.

Filters are placed in embankment zones, foundations, or other areas of hydraulic structures for two pur-poses To intercept water flowing through cracks or openings in a base soil and block the move-ment of eroding soil particles into the filter. Soil particles are caught at the filter face, reducing the flow of water through cracks or
The results were collected from filters operated at 20 mhr 8 gpmft2 filtration velocity with no flocculation. Therefore the results are a direct comparison between the different filtration media. At slower water flowrates the results for AFM improve exponentially Summary of filter media performance at 1 and 5 microns, water flow 20 mhr
The filter can then be restarted. After water quality reaches an acceptable level, the filter can then be put back on line. 1.4 Rapid Sand Filtration. In rapid sand filtration much higher application velocities are used. Filtration occurs through the depth of the filter. A comparison of rapid and slow sand filtration is shown in Table 1.
Mar 23, 2009 It is typified by the conventional sand filter, which clarifies water by depth filtration mechanisms as it flows through a bed of graded sand that may be up to one metre in depth. Many different granular and crushed materials have been used to form the deep beds employed in the large gravity and pressure filters common to the water purification ...

Due to this difference, nylon net filters possess a uniform, large pore structure similar to a mesh, a pore size 5.0 m, and a reduced thickness in comparison to nylon membrane filters. Isopore polycarbonate membrane filters offer well-defined pores and a smooth transparent surface ideal for use with optical or electron microscopy.
