mechanical filter

Multi media filter is a process that uses one or several filtering media to pass water with high turbidity through a certain thickness of granular or non granular materials under a certain pressure, effectively removing suspended impurities and clarifying water. Commonly used filter media include quartz sand, anthracite, manganese sand, etc., mainly used for water treatment turbidity removal, softening water, and pre-treatment of pure water. The effluent turbidity can reach below 3 degrees. Multi media filter is a commonly used pre-treatment device for deep water purification, which can be filled with different filter materials according to process requirements.

The adsorption principle of activated carbon isForm a balanced surface concentration on the surface of its particles, and then adsorb organic impurities into the activated carbon particles. The initial adsorption effect is very high. But over time, the adsorption capacity of activated carbon will weaken to varying degrees, and the adsorption effect will also decrease accordingly. If the water in the aquarium is turbid and the organic content is high, activated carbon will quickly lose its filtering function. Therefore, activated carbon should be cleaned or replaced regularly.

The size of activated carbon particles also has an impact on adsorption capacity. Generally speaking, the smaller the activated carbon particles, the larger the filtration area. So, powdered activated carbon has a large total area and good adsorption effect, but it is easy to flow into the aquarium with water, which is difficult to control and rarely used. Granular activated carbon is difficult to flow due to its particle formation, and impurities such as organic matter in water are also not easily blocked in the activated carbon filter layer. It has strong adsorption capacity and is easy to carry and replace.

The adsorption capacity of activated carbon is directly proportional to the contact time with water, and the longer the contact time, the better the filtered water quality. Attention: The filtered water should slowly flow out of the filter layer. New activated carbon should be washed clean before its first use, otherwise black water may flow out. Before installing activated carbon into the filter, a 2-3 centimeter thick sponge should be added at the bottom and top to prevent large particles such as algae from penetrating. After using activated carbon for 2-3 months, if the filtration effect decreases, new activated carbon should be replaced and the sponge layer should be replaced regularly.

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