According to the process and package form adopted, it can be divided into two types: tank type and tube type. The canister type directly uses activated carbon granules and the lower slab quartz sand has high effluent efficiency, but regeneration is relatively troublesome. The tubular type is obtained by adding activated carbon particles to a binder such as heating and sintering. Both use and regeneration are more convenient.
(2) Filler-purified water activated carbon
The purified water activated carbon series is made of high-quality nut shell or coal, using advanced equipment, and the microcomputer controls the production process conditions and refined. The product has developed pore structure, high strength and low impurity content. The granules are suitable, the resistance is small, and the regeneration is easy. It has excellent effect on water purification. It not only removes the smell of water, but also improves the purity of water. It also has various impurities such as chlorine, mercury, chromium, arsenic, lead, cyanide, pesticides and other harmful substances in the water. Very high removal rate. It can be widely used to fill all kinds of large, medium and small water purifiers. At present, pure water, mineral water production, and indoor and outdoor air purification are widely used.
(3) Application
Activated carbon has been used for water treatment for a long time. The dechlorination of water is preferred for activated carbon adsorption, which can be completed in a very short contact time. Therefore, when the activated carbon filter is used for dechlorination, the flow rate can reach 10 gpm/ft2 or higher. Activated carbon can adsorb organic matter and can trap organic matter on loose surface. When activated carbon filter is used to remove odor and odor in water, this adsorption process needs sufficient contact time, so the working flow rate should not be higher than 5 gpm/ Ft2. The regeneration backwashing of the activated carbon filter is quite important. The backwashing flow rate should be carried out at 10 gpm/ft2 for about 10 minutes; followed by the positive washing and discharging steps for about 5 minutes. The backwashing of activated carbon must be as careful as possible, otherwise the fragile charcoal will be broken and flow away with the backwashing water, and the "attachment" of these organic matter will become heavier and sink to the bottom of the filter. Reduce the adsorption capacity of the entire filter. After a period of use, usually months to 2 years, the charcoal adsorption capacity will be exhausted and the filter bed must be replaced with new activated carbon.
