Filter

Detailed Product Description

First, an overview of

Activated carbon filter to remove impurities in raw water, suspended solids, organic matter, pigment, such as chlorine colloid. Is widely used in water, food and drink water, mineral water and electronics, printing and dyeing, paper making, chemical industry, water quality of the pretreatment and post-secondary treatment of industrial waste water filtration. Is also used in water reuse systems, swimming pool water circulation system, the depth filter. For the suspended solids in industrial waste water has a very good removal.

2, device characteristics

Is widely used in water treatment processes, such as the depth of water purification; brewing, beverage and other industries the depth of water purification treatment; processes condensate oil removal, in addition to organic matter such as processing; water, high pure water preparation process of the pre-treatment; industrial purification of wastewater and sewage treatment. Equipment operation, they were treated water from the filter into the upper part, top-down through the activated carbon filter layer, the use of activated carbon adsorption, so that the water of harmful substances, such as organic matter, colloids, microorganisms, oils, chlorine, and the olfactory flavor such as adsorbed on the surface of activated carbon have been removed, when the activated carbon filter layer "failure", the method can be used to backwash recovery adsorption capacity.
Activated carbon filters work is accomplished through the carbon bed. Composed of carbon bed of activated carbon particles have a very large number of micropores and specific surface area, has a strong physical adsorption capability. Of water through the carbon bed, water and organic contaminants have been effectively activated carbon adsorption. In addition, the non-crystalline part of the surface of activated carbon, there are some oxygen tube to corporations so that the water through the carbon bed of organic pollutants are carbon and effective absorption. Activated carbon filters are a more commonly used in water treatment equipment, as a water desalination system, after pre-treatment level to ensure effective service life, improve water quality, pollution prevention, particularly to prevent post-stage reverse osmosis membranes, ion exchange resins, etc. I state pollution free oxygen toxicity.

² filtration efficiency, resistance to deal with traffic large number of less backwashing;

² system maintenance is simple, efficient;

² can be realized fully automatic operation, easy to use;

5, the main technical parameters

1, filter tank diameter: Φ800m

2, filtering speed: 10m / h

3, filter media: activated carbon

4, filter capacity: 5m ³ / h

6, filter tank filter installation instructions

Material Preparation:

1, pebble: size: 40 ~ 80mm, 0.2m ³;

2, gravel: size: 5 ~ 15mm, 0.4m ³;

Gravel and activated carbon are transported to the site.

1, open filter tank on a manhole, and closed the lower part of the filter tank refueling port;

2, first large-size filter into the jars at the end gravel, and pave the way;

3, and then into the small particle size of pebbles, and pave the way;

4, finally into the activated carbon, and pave the way, and then people on the filter pot holes closed;

Filtering tanks put into use before the preparation:

1, check valve filter tank on the status of all compliance requirements:

2, the first point of moving into the pump, observe whether the direction of motor rotation of the impeller and pump volute marked on the spin to the same (Note: The test pump pump before and after the valve must be opened, to ensure there is water before the pump test pump).

7, pay attention to matters

1, filling filter

Filter is to ensure that the key effect of water treatment must be based on technical requirements for filter materials ready, and put requests to fill fill. Washed clean before packing required to remove the debris, according to grain-level hierarchical classification type hydraulic loading.

2, supplementary and replacement of filter

Filter is damaged, run and operate the relevant material, such as the filter run time is too long, the water quality is unclear or arbitrary layer of filter layer occurs, should be promptly replaced or re-grading filling.

3, filter operation

When the inlet pressure and outlet pipe pressure gauge displayed on the pressure difference reaches a certain value, the need for backwashing of the filter tank, anti-washing must be controlled when the anti-washing of the pressure and flow.
