Natural activated carbon for water treatment

Akdolit^® Hydro-Sorb is a highly activated granular coal made from coked coal. The porous structure of Akdolit^® Hydro-Sorb is specially adapted to the adsorption of different organic compounds contained in the water.

Akdolit^® Hydro-Sorb is mainly suitable for the treatment of industrial, swimming pool and drinking water, especially for :

• the sorption of odours, flavours and colourings
• reducing the quantities of organic substances
• dechlorination and de-ozonisation.

A low content of certain contaminants (such as iron and manganese) is required before the Akdolit^® Hydro-Sorb treatment.

Water with a low turbidity can be treated with Akdolit^® Hydro-Sorb as the abrasion resistance of this activated charcoal permits rinsing at usual water velocity conditions. However, it must be noted that high turbidity levels may interfere with the desired sorption of organic substances contained in the water.

High-performance deacidification for strong acids

Akdolit^® Hydrolit Mg G is a spheroidal filter material consisting of magnesium compounds (MgO * Mg(OH)₂) and successfully used in industrial water treatment. Akdolit^® Hydrolit Mg G is employed for the neutralisation of many components, for instance:

• Sulphuric acid (H₂SO₄)
• Hydrochloric acid (HCl)
• Nitric acid (HNO₃)
• Acetic acid (CH₃COOH)

in open and closed systems.

This may be the neutralisation of acidic ion exchanger regeneration effluent, acidic industrial wastewater low in heavy metals or acidic combustion condensates.

If the required quantity, depending on the type of acid, the concentration of the acid and the grain size, is determined, the water neutralisation can take place automatically until the pH value required for the discharge into the sewer system or the receiving water-course is reached.
