Activated carbon filter design calculation pdf.

The diameter and height of the design column m. The choice of equipment depends on the severity of the organic removal problem the availability of existing equipment and the desired improvement of adsorption condition design calculations on dechlorination by granular carbon filters considering. For voc contact time is 7 min. Just make sure you use the same volume units to do the calculation.

A gac filter must have sufficient ebct to do the job plus enough safety margin to cover variations in the quality of the water being treated. A smaller diameter should not be. Activated carbon water filtration. This paper presents basic design and fabrication of activated carbon filter from agricultural waste coconut and palm kernel shells for water purification in the northern region of ghana.

Granular carbon can be used after conventional filtration of suspended matter or as a combination of filtration adsorption medium. Activated carbon ac is a. The design maximum solid phase concentration q o kg kg. The design reaction constant k 1 l s kg.

For chlorine contact time is 2 min. A flow of water through that filter at 2 5 gpm has an ebct of 7 5 2 5 3 minutes. 200 mesh 74 µm typical range 10 50 µm bulk dry apparent density 0 34 to 0 74 kg l. Granular activated carbon gac particle size.

Empty bed contact time is calculated as volume of empty bed divide by flow rate. This document addresses various adsorption media types applicability use of various adsorption process technologies equipment and ancillary component design availability. Calculation for activated carbon filter design. Depending on the type of water suspended solids concentration oil and grease cod bod and pesticides contents activated carbon filters are sized differently but the basic design data to clarify natural waters is the following.

Following the rules mentioned above the value decided was 5 0 cm. Carbon is a substance capable of absorbing impurities in polluted contaminated water 11. Due to the activated carbon effective size was known the column diameter was the first parameter to be estimated. Clude granular activated carbon gac and other alternative adsorption carbon media such as powdered activated carbon pac and non carbon adsorbents.
