Fully automatic multi-medium quartz sand filter

Product Introduction

Multi-medium filter is the use of more than two kinds of filtration media, under a certain pressure to the high turbidity of the water through a certain thickness of granular or non-granular material, so as to effectively remove suspended impurities to make the water clear process, commonly used filter material quartz sand, anthracite, manganese sand, etc., mainly used for water treatment turbidity removal, softening water, pure water pre-treatment, the effluent turbidity can reach 3 degrees below

Introduction to Structure

Multi-medium filter is widely used in water treatment process, multi-medium filter is mainly composed of the following parts: supporting pipeline and valve. The filter body also includes :① cylinder; (2) backwash pipe; ③ water distribution assembly; (4) Support assembly; ⑤ filter material; ⑥ Exhaust valve (external), etc

Principle of product

Multi-medium filter (also known as mechanical filter) is a layered anthracite, sand, fine garnet or other materials for the bed, a typical multi-medium filter.

The top layer of the bed is made up of the lightest and coarsest grades of material, while the heaviest and finest grades are placed at the bottom of the bed. The principle is to filter by depth - larger particles in the water are removed at the top layer and smaller particles are removed deeper in the filter medium. So that the water quality can reach the standard after crude filtration.

The equipment is pressure type, the principle is that when the raw water passes through the filter material from top to bottom, the suspended matter in the water is intercepted 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, because the sand in the filter layer is more closely arranged, so that the particles in the water have more opportunities to collide with the sand, so the water flocculation, suspended matter and sand surface adhesion to each other, the impurities in the water are intercepted in the filter layer, so as to get the clarified water quality. The effluent suspended matter after filtration can be less than 5 mg/l.

Product Features

1, porous media filter is widely used in the process of water treatment, can be used alone, but most of the water is as a deep treatment (exchange resin, electrodialysis, reverse osmosis) of the pre-filtration.

2. Multi-medium filter is a commonly used pretreatment device for deep water purification, which can be filled with different filter media according to the technological requirements.

3, multi-media filter material can be made of glass steel, A3 steel anticorrosion or lining glue, stainless steel. Operation mode has automatic and manual two forms, automatic control is imported from the United States of America automatic controller and gas, hydraulic valve control, easy to operate and easy to maintain, in all walks of life in the water treatment process of the pre-treatment device has been widely used.

4, multi-media filter (including double filter material) filter material should have enough chemical stability, the relative density and particle size of each medium should be different, composed of anthracite and quartz sand double filter material used for the relative density of anthracite is 1.4 -- 1.6, particle size is 0.8 -- 1.8mm, quartz sand relative density is 2.6 -- 2.65, Particle size of 0.5-1.2mm; 3 layer filter material filter in addition to the above two kinds of filter material can also use manganese sand, magnetite and other heavy ore, its relative density is 4.7-5.0, particle size is 0.5-4mm.
