RO water system Multi-media filter vessle

A multi-media filter (also known as mechanical filter) is a typical multi-media filter which is composed of

layers of anthracite, sand, fine garnet or other materials as the bed layer.The top floor of the bed is made

up of the lightest and coarsest grade materials, while the heaviest and finest grade materials are placed in

the lower part of the bed.The principle is to filter by depth - larger particles in water are removed at the

top and smaller particles are removed at deeper depths in the filter medium.So that the water quality

reaches the standard after rough filtration.The device is pressure-type, and its principle is that when raw

water passes through the filter material from top to bottom, suspended substances in the water are

retained by the surface of the filter layer due to adsorption and mechanical flow resistance.When the

water flows into the middle of the filter layer, as the sand particles in the filter layer are arranged more

closely, the particles in the water have more chances to collide with the sand particles, so that the

flocculation, suspension and sand surface in the water adhere to each other, impurities in the water are

trapped in the filter layer, thus obtaining the clarified water quality.The filtered effluent suspension may be

less than 5 mg/l.Characteristics of the editor1. The porous media filter is widely used in the process of

water treatment and can be used alone, but most of them are used as the pre-filtration of the deep water

treatment (exchange resin, electrodialysis, reverse osmosis).2. Multi-media filter is a common

pretreatment device for deep purification of water, and different filter materials can be added according to

the process requirements.3. The multi-medium filter material can be made of fiberglass, A3 steel

anticorrosion or rubber lining, all stainless steel.There are two types of operation: automatic control and

manual control. Automatic control adopts automatic controller and pneumatic and hydraulic valve imported

from the United States. It is easy to operate and maintain.4, many media filters (including double filter

material filter) of filtering material should have enough chemical stability, relative density and particle size

of each medium should have certain difference, double layer composed of anthracite coal and quartz

sand filter material filter used in anthracite relative density is 1.4-1.6, particle size of 0.8 -- 1.8 mm, quartz

sand relative density is 2.6-2.65, particle size of 0.5-1.2 mm;In addition to the above two kinds of filter

materials, the 3-layer filter material filter can also use heavy ores such as manganese sand and

magnetite, with a relative density of 4.7-5.0 and a particle size of 0.5-4mm.
