An air filter construction that provides a high capacity and high efficiency and is suitable for use with high performance automobile internal combustion engines includes a dual filter media in which a semi-rigid fibrous depth filter element is located on the upstream side and the downstream face of the element bears against pleats formed in a pleated paper material.

The filter incorporates a particulate filter. The filter must be marked with at least the filter type, the colour code Red-White, together with the filter class, e.g., Hg-P3. AX filters are for use against certain low boiling organic compounds. They are classified as in only one type and class, AX.

Anthracite is used as a vital component in pre-RO filters. Though it is rarely used alone, it is often used as part of a dual media system alongside sand(1) or alongside both sand and ground garnet in a mixed media filter. Collectively, these filters provide effective …

The media are loaded by density—the most dense in the bottom of the tank, the least dense on top. This produces a filter with excellent flow rate and and relatively easy backwash properties that will filter down to ten microns. The most common media mix is (top to bottom): anthracite, filter sand, garnet 30 X 40, garnet 8 X 12, and gravel.

The major advantages of dual-media filtration are higher rates and longer runs. Anthracite/sand/garnet beds have operated at normal rates of approximately 5 gpm/ft² and peak rates as high as 8 gpm/ft² without loss of effluent quality. CAPPING OF SAND FILTERS. Rapid sand filters can be converted for mixed media operation to increase capacity ...

Dual media filters provide very efficient particle removal under the conditions of high filtration rate. Inside a sand-anthracite filter is a layered bed of filter media. The bed is graded from bottom to top as follows: Having the filter media graded this way enables the sand anthracite Filter to run for longer times before a backwash is necessary.

An ideal duplex filter working principle should allow for overhaul of filter media while running, and the duo filter element in the assembly provides redundancy. Also, the duplex filter element surface is critical in determining the differential pressure, hence, it is fitted with an electrical switch, which closes contacts to alert a lodged filter.

Ultra-capacity Filtration™. System:3 Mod Media filters combine a balanced-flow and integral manifold design, plus an easily cleaned media element. And, modular filter tanks permit quick change of filter media. The result is a filter system that not only requires less frequent cleaning but is also easy to clean.

Anthracite promotes higher service flow rates and longer filter runs with less head loss than single media filter beds. Backwash rates are reduced as well. Low uniformity coefficient anthracite filter media extends the life of your filter before the media must be changed out. Low uniformity coefficient anthracite typically produces consistent improvements in turbidity removal,... Read more →

In the Automotive range of products, filters are made that protect relevant mechanical and electronic components. Sefar produces high-precision screens made of monofilament fabric for safety filters to protect valves, pumps and sensors. Depth filtration media is required when high dirt pick-up is required; an example is the Fuel/AdBlue filter.

Multimedia filters are also sometimes referred to as dual media, anthracite, granular media, multi-layer or pressure filters. Multi media filters use graded support media layers over the under-drain to prevent the layers from migrating into each other during backwashing. Dissolved Iron Removal uses a specialty manufactured filter media to ...

Use media initial resistance vs. face velocity data/curves for preferred media. Typically, initial resistance is 0.10″ wg (water gauge) or less. Select appropriate air filter model and frame thickness to accept selected media thickness. For example: Disposable, white UFM-50 media fits in any frame thickness (0.30″, 0.43″ or 0.50″).

Fluid Systems water filter sand is washed, clean dried, and screened to meet exacting specifications with strict adherence to quality control. Gravel & Pebbles Fluid Systems Gravel and water filter pebble is composed of sub-angular, hard, durable, and dense grains of predominately siliceous material.

With dual media filtration, the upper layer of the media provides in depth filtration and large dirt storage capacity. The finer sand in the bottom of the filter (with its low uniformity co-efficient) remains largely unpolluted and it is available to provide very effective filtration. By …

Design the structural components of a dual-media rapid filter for the city of Apple Valley. The maximum day flow rate is 45,000 m 3 /d. The design criteria and media analyses are given below. Assume a 525 mm diameter pipe from the gullet is to carry the wash water at a velocity of 1.5 m/s.

filter water with an average turbidity of less than 25 NTU. Dual and multi-media filters are used with direct filtration. They are able to remove more suspended material per cubic foot of filter media than sand filters. Direct filtration plants have a lower capitol cost. However, the process cannot handle large variations in raw water turbidity.

Fortunately, dual media filters have a capacity of functioning even under con­ditions of poor pre-treatment and in­creased flow. Experience in the West as well as in India confirm this. Another advantage in adoption of these filters is that existing filters can be converted to dual media filters with minor changes at a very low cost.

Raw water is passed through CHEMTRONICS Multigrade Sand Filter at a pressure of 3.5 kg / cm2 to reduce the suspended solids present in the raw water. The filter will effectively remove up to 30 – 50 micron of the suspended solids to less then 5 ppm. The filter will have to be washed with raw water for 20 to 30 minutes daily.

media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging.

Dual-media filters, like rapid sand filters, are cleaned by hydraulic backwashing (upflow) with potable water. Thorough cleaning of the bed makes it advisable in the case of single medium filters, and mandatory in the case of dual- or mixed-media filters, to use auxiliary scour or so-called surface wash devices before or during the backwash cycle.

Garnet, with its high density, is heavier than most other filter media. Garnet's higher density provides stability within your dual media bed, allowing the filter sized garnet to filter down to 10 – 20 micron particulates. Filter sand or anthracite are used effectively as the strata of bed.
