Active Carbon Filter Group
 
While Rielli active carbon filters retain the organic substance and free chlorine in the water, improving the water in terms of taste, smell and color. In this system, active carbon is used as filter material and gravel as filling material.

Active carbon is one of the oldest and multi-functional materials used in the treatment technology with the wide surface due to its complex structure.

Selection of Equipment:

Efficiency of the active carbon filter is determined by characteristics of the active carbon used in the filter bed and correct selection of the surface speed. When determining the filtration speed, the inorganic substance, free chlorine, smell, color quantity as well as appearance of the water should be taken into consideration. While, for filtration of the city mains water, the speed is taken 40 m3/m2/h as maximum, the filtration speed varies between 15 m3/m2/h and 30 m3/m2/h depending on the quantity of organic substance and free chlorine. For picking up the chloramines components in the water, much lower values are used. In the active carbon filters, the paths opened by the water passing through the filter are distributed during back washing, homogeneity is imparted to the filter bed.

Operating Principle of the Active Carbon Filter

Active carbon filters operate full automatically without human intervention. Performing automatic back washing operation for 20 minutes daily, the active carbon filter renews itself in this way.

Filter Bodies

Filter bodies are fiberglass of special mix. Tested under 16-bar pressure, the operating pressure of these bodies is 10 bars.

Control Mechanism

Full-automatic mechanical valves are used on the filters. The surface of the valves in contact with water is brass and the remaining parts are of plastic material. Filters start to perform back washing under time control. Maximum service temperature that can be used by the valves is 50oC and their operating pressure is 1.8 – 8.8 bar.
