Activated carbon filter


Application scope: widely used in food, medicine, electronics, chemical industry, industrial waste water and other industries.

Working principle:

High content of organic matter in the adsorption of activated carbon adsorption principle is: in the particle surface

to form a layer of balance of the surface concentration, the organic matter impurity adsorption onto activated

carbon particles, using the initial effect is very high. But time a long, active carbon adsorption capacity will be

different degrees of weakening, the adsorption effect is decreased. If the aquarium water turbidity, water,

activated carbon will soon lose their filtering function.

So, the activated carbon should be regularly cleaned or replaced. Activated carbon particle size on adsorption


Generally speaking, activated carbon particles is small, the filter area is large. So, powdered activated carbon

with a total area of the largest adsorption effect Paving in black ink, forming because of the best, but powdered

activated carbon easily with water flowing into the aquarium, difficult to control,rarely used. Granular activated

carbon particles is not easy to flow,water organic matter impurity in the activated carbon filter layer is not easy

to block, and its adsorption ability, carrying is convenient to replace. The active carbon adsorption capacity

and water contact time is proportional to the contact time is long, filtered water quality is better. Note: filter the

water slowly out of the filter layer.

The activity of carbon in the first before use should be washed clean, otherwise water outflow. Activated carbon

filter is loaded, it should be at the bottom and the top 2 ~ 3 cm thick sponge. To prevent algae and other large

impurity particles penetrate,activated carbon used for 2 to 3 months, if the decline in the filtering effect should

be the new exchange, activated carbon, sponge layer to change regularly. Activated carbon filter pressure

vessel is a filled with coarse sand cushion and high quality activated carbon of pressure vessels.


Obvious adsorption removal effect, but also reduce the cod. Can further reduce the RO feed SDI value, ensure

the SDI<5 TOC<2.Oppm. in water pretreatment system, activated carbon filters to adsorption level filtering to

remove the residual chlorine to prevent reverse osmosis membrane by the oxidative degradation, but also

absorption over the previous level leakage of small molecule organic compounds and other pollutants, the

peculiar smell in water, colloid and pigment, heavy metals and other.

Prevent effectively can manage effectively to complete the activated carbon filter is through the carbon bed.

Constitute the carbon bed of activated carbon particles have very many micropores and great specific

surface area, has very strong physical adsorption capacity. The water through the carbon bed, water

organic pollutants by activated carbon adsorption. In addition, activated carbon surface non crystalline

part has some oxygen group, the carbon bed water organic pollutants by activated carbon adsorption.

Activated carbon filter is a commonly used water treatment equipment, as water desalination system

before treatment can effectively guarantee the equipment service life, improve water quality, prevent

pollution, especially after the reverse osmosis membrane, ion exchange resin Lipid and other free

oxygen poisoning.

Effect of activated carbon adsorption filter effect and the service life of the main factors: the type and

concentration of pollutants,the retention time of air in the filter material, the temperature and humidity

of the air. The actual selection to according to pollutant type,concentration and volume and other

conditions to determine the form and activated carbon filters are. The upstream and downstream

of the activated carbon filter should have good dust filter and its efficiency specifications should

be not less than F7.

The upstream filter to prevent dust blockage of the activated carbon materials; downstream of the filter

stopped activated carbon itself dust.
