How to choose powdered activated carbon for water treatment

We must first understand that powdered activated carbon can be divided into powdered activated carbon for water treatment, powdered activated carbon for sugar, powdered activated carbon for medicine, and powdered activated carbon for industrial use.

There are differences in appearance between powdered activated carbon and granular activated carbon for water treatment. activated carbon manufacturer south africa 65%-95% of the powdered activated carbon can pass through 325 screen, more than 90% can pass through 200 screen, and its density is between 0.36-074g/cm.

In water treatment, powdered activated carbon and granular activated carbon each play an important role. Powdered activated carbon has been widely used to remove color, smell, taste and trace organic matter in water. The dosage is usually 2-15mg/L. www.granular-activated-carbon.com The adsorption cycle time of powdered activated carbon is short, the dosage method is simpler, the cost is lower, and the carbon type can be replaced at any time according to the water pollution status. The application continues to expand.

The use of powdered activated carbon in foreign countries to remove organic matter, color and odor substances in water has achieved successful experience and good removal effect, and the investment of powdered activated carbon equipment is small, the price is low, and the adsorption speed is fast. Strong adaptability to water pollution accidents.

The granular activated carbon is used for the advanced treatment of drinking water and is usually used in conjunction with sand filters, and is widely used in water plants. Used in solvent recovery, organic gas adsorption, catalyst carrier, etc.; the use of powdered carbon is relatively narrow and usually used in the fields of decolorization, purification, and catalyst carrier.

The size of the granular activated carbon also affects the adsorption capacity. We all know that the smaller the activated carbon particles, the larger the specific surface area. The powdered activated carbon has the largest total area and has the best adsorption performance, but the powdered activated carbon is easy to run away with water and is difficult to manipulate, so it is rarely used.

The granular activated carbon is not easy to move due to the formation of particles, and impurities such as organic matter in the water are not easy to be blocked in the activated carbon filter layer. It has strong adsorption performance, long service life and convenient replacement.
