The effect of activated carbon adsorption in pure water treatment system

Dec 25, 2017

Activated carbon adsorption is the porous nature of activated carbon, which can be used to remove one or more harmful substances in the water.

Activated carbon adsorption to remove organic matter, colloid, microorganism, residual chlorine, and odor and so on has outstanding effect.

Activated carbon has a certain reduction effect, which is obvious to remove the oxidant in water.

Because of active carbon adsorption has a certain saturation, when the saturated adsorption capacity, adsorption of activated carbon filter function will be greatly decreased, so the activated carbon to wash (wash backwashing is) on a regular basis, usually in time each year to replace activated carbon (depending on the actual situation).

Periodic sterilization and cleaning can control bacterial reproduction. In order to achieve full sterilization effect, the system terminal adopts ultraviolet sterilization or ozone sterilization.

That are worth noting is that at the early stages of the use of activated carbon (new or replacement operation early active carbon), a small number of extremely fine powder activated carbon may also be with flow into the Reverse osmosis system, and cause the soak the fouling of membrane flow path, the operating pressure increased, decreased water rate and the system of differential pressure rises, and the damage effect is difficult to use the general way to clean removal.

Therefore, it is necessary to wash the activated carbon and remove the fine powder before it can be sent to the pure water system in the back.
