Activated carbon filter pressure vessel is a pressure vessel filled with coarse quartz sand cushion and high-quality activated carbon.

Activated carbon filter function: In the water pretreatment system, the activated carbon filter can absorb the residual chlorine that cannot be removed in the previous stage filtration to prevent the subsequent stage reverse osmosis membrane from being oxidized and degraded, and at the same time, it also adsorbs small molecular organic matter leaked from the previous stage. Pollutants have obvious adsorption and removal effects on peculiar smell, colloids and pigments, heavy metal ions, COD, etc. in water. The SDI value of RO influent can be further reduced, ensuring SDI<5 and TOC<2.Oppm.

The work of the activated carbon filter is completed by the carbon bed. The activated carbon particles that make up the carbon bed have a lot of micropores and a huge specific surface area, and have a strong physical adsorption capacity. The water passes through the carbon bed, and the organic pollutants in the water are effectively adsorbed by the activated carbon. In addition, there are some oxygen-containing tube energy groups on the non-crystalline part of the activated carbon surface, so that the organic pollutants in the water passing through the carbon bed are effectively adsorbed by the activated carbon. Activated carbon filter is a kind of more commonly used water treatment equipment. As the pretreatment of water treatment desalination system, it can effectively ensure the service life of the subsequent equipment, improve the effluent water quality and prevent pollution, especially to prevent the subsequent reverse osmosis membrane, ion exchange resin, etc. Free residual oxygen poisoning pollution.

The main factors that affect the adsorption effect and service life of activated carbon filters are: the type and concentration of pollutants, the residence time of airflow in the filter material, the temperature and humidity of the air.

In actual selection, the type of filter and the type of activated carbon should be determined according to conditions such as the type of pollutant, the concentration and the air volume of the treatment.

The upstream and downstream of the activated carbon filter should have a good dust filter, and the efficiency specification should not be lower than F7. The upstream filter prevents dust from clogging the activated carbon material; the downstream filter blocks the dust generated by the activated carbon itself.
