The system uses fruit shellsActivated carbon filterIt can adsorb electrolyte ions and also perform ion exchange adsorption. Due to the adsorption effect, the concentration of adsorbed substances on the surface increases, thus also playing a catalytic role, removing pigments, odors, a large amount of biochemical organic matter in water, reducing the residual chlorine value and pollutants in water, and removing trihalides in water(THM)And other pollutants, with very low operating costs.

Activated carbon filterIt is mainly used to remove organic matter, colloidal silicon and residual chlorine from water(Cl2)It has a strong adsorption capacity for odors, color, and heavy metal ions. The beverage industry selects purified water charcoal to improve the taste of the product. Activated carbon filters are mainly used for water purification in mineral water, various pure water processes, swimming pools and other processes. It has the functions of deodorization, eliminating unpleasant odors, and removing organic substances such as chloride ions in water. The shell is made of stainless steel or carbon steel, and the packing material is activated carbon for water purification.

1. The cylinder body of the activated carbon adsorption filter adopts a hydraulic simulation length-diameter design, and the particle size is reasonable with a specific surface area greater than 1000㎡/g The activated carbon, which not only has the functions of upper filtration but also lower adsorption, greatly enhances the purification degree of the produced water and the service life of the carbon.

2. The residual chlorine content in the water after treatment by the activated carbon adsorption filter:≤0.1PPM.

3. It has a good performance in treating odors, organic matter, colloids, iron and residual chlorine in water bodies.

4. It also has a very good effect on reducing the turbidity and color of water bodies, purifying water quality, and reducing pollution to subsequent systems (reverse osmosis, ultrafiltration, ion exchangers).

Ii. Working Principle of Activated Carbon Filter

The adsorption principle of activated carbon is that a balanced surface concentration is formed on the surface of its particles. The size of activated carbon particles also has an impact on the adsorption capacity. Generally speaking, the smaller the activated carbon particles are, the larger the filtration area will be. Therefore, powdered activated carbon has a large total area and good adsorption effect, but it is very easy to flow into the water tank with water and is difficult to control, so it is rarely used. Granular activated carbon, due to its formed particles, is not easy to flow. Organic matter and other impurities in water are also less likely to clog the activated carbon filter layer. It has a strong adsorption capacity and is convenient to carry and replace.

The adsorption capacity of activated carbon is directly proportional to the time it is in contact with water. The longer the contact time, the better the quality of the filtered water. Note: The filtered water should flow out of the filter layer slowly. New activated carbon should be washed clean before its first use; otherwise, black ink will flow out. Activated carbon should be added at the bottom and top before being loaded into the filter2～3A centimeter-thick sponge is used to prevent large particles of impurities such as algae from penetrating in, and activated carbon is used2～3After one month, if the filtration effect declines, new activated carbon should be replaced and the sponge layer should also be replaced regularly.

The activated carbon filter pressure vessel is a type of pressure vessel filled with a coarse quartz sand cushion layer and high-quality activated carbon.

A balanced surface concentration is formed on the surface of activated carbon particles, and then organic impurities are adsorbed into the activated carbon particles. The adsorption effect is very high in the initial stage of use. However, over time, the adsorption capacity of activated carbon will weaken to varying degrees, and the adsorption effect will also decline accordingly. If the water in the aquarium is turbid and has a high content of organic matter, the activated carbon will soon lose its filtering function. Therefore, activated carbon should be cleaned or replaced regularly.

The activated carbon filter was designed and manufactured by us after absorbing the suggestions of a large number of users. It has changed the original direction of water inlet and discharge, making the water purification effect better and is widely welcomed by users. This product is an essential piece of equipment for water treatment of domestic drinking water and other water uses. Turbidity<5millimeter/After being processed by this equipment, liters of clear water can be obtained as clear and transparent, dry and mellow, sterile, odorless and directly drinkable water. The purified water meets the national drinking water quality standards.

Iii.The filtration process of the filter

The filter material in the activated carbon filter adsorber can be filled at the bottom0.15~0.4A meter-high quartz sand suction can be used as a support layer, and the particles of quartz sand can be adopted20-40Millimeters, can be filled on quartz sand1.0-1.5Granular activated carbon is used as the filter layer. The filling thickness is generally1000－2000mm.

Before loading the activated carbon filter, the bottom filter material, quartz sand, should undergo a solution stability test and soaking24After hours, the following requirements must be met: the increase in the total solid content does not exceed20mg/L. The increase in oxygen consumption does not exceed10mg/L. After soaking in an alkaline medium, the increase in silicon dioxide does not exceed10mg/L.

After the quartz sand of the activated carbon filter is thoroughly rinsed, it should be carefully cleaned when loaded into the equipment. The water flow should be from top to bottom, and the dirty water should be discharged from the bottom until the water is clear. Then, granular activated carbon filter material should be loaded and cleaned again. The water flow should be from bottom to top, and the dirty water should be discharged from the top.

The main function of the activated carbon filter is to remove large-molecule organic substances, iron oxides and residual chlorine. This is because organic substances, residual chlorine, and iron oxides can easily cause poisoning of ion exchange resins. Moreover, residual chlorine and cationic surfactants not only poison the resins but also damage the membrane structure, leading to the failure of reverse osmosis membranes.
