Question: Activated carbon for decreasing NOM, TOC, COD
Published on by mohamed zakaria elhanafy, Assistant Manager at Mowah For water solution in Technology
What should be the thickness of the activated carbon layer on gravity filter mixed with sand?
Activated carbon for removing "Natural organic matter 20 ppm" ,TOC =15ppm ,colour 13 ,COD range "10-15" ,TSS=0-10 """.
The source of this water is Tertiary sewage effluent "TSE Water".
Thank you!

you can check on Empty Bed Contact Time (EBCT) as a check parameter for the AC's adsorption function. I usually use it in conjunction with designing it as a filter via its filtration rate. The EBCT is a designer's choice and usually based on bench testing.

Hello SIR,There is calculation for quantity and thick ness and depend upon surface area of activated membrane.The velocity should be 8-12 m3/m2/day

Adsorption by Activated Carbon (AC) depends on Iodine Value and the contact time between AC and water. There is no mathematical relationship between height of AC bed and concentration of organic matter. pH & temperature plays very important role. It is higher at lower temperature & pH level. I always ensure to have bed height around 1 M and surface loading rate 15 to 20 m3/m2/hr. This ensure maximum contact time with AC. For details please contact on rvsceipl@gmail.com

Hi Raj, please not that there is a messaging functionality inside The Water Network. easier to connect then you can message mohamed zakaria elhanafy on the platform instead of relying on emails
