Activated Carbon Filter (ACF) Sewage Water Treatment Plant
AAA:
01. What is the raw water? What is the flow rate do you require?
02. What will the be treated water used for?
03. What is the power supply in your counrty?
An Activated Carbon Filter (ACF), like the Pressure Sand Filter, is a tertiary treatment unit. It receives the water that is already filtered by the Pressure Sand Filter and improves multiple quality parameters of the water: BOD, COD, Clarity (turbidity), color and odor.
This filter uses the adsorption action of activated carbon. Activated carbon is typically manufactured from coconut shell or charcoal, the activation process creating a highly porous material with a very large surface area. Organic pollutant molecules are physically adsorbed and held fast within the catacomb-like porous structure of the activated carbon. Granular activated carbon is typically used for this purpose. The water filtered by the Pressure Sand Filter enters the Activated Carbon Filter. Unlike in the case of the sand filter, trapped molecules in the carbon cannot be backwashed and got rid of. Hence, activated carbon in the filter has a finite capacity to adsorb and hold the pollutants, after which the carbon is said to be exhausted. The exhausted material is removed from the filter and disposed off: Fresh activated carbon is charged in the filter.
How It Works
This filter uses the adsorption action of activated carbon. Activated carbon is typically manufactured from coconut shell or charcoal, the ?activation? process creating a highly porous material with a very large surface area. Organic pollutant molecules are physically adsorbed and held fast within the catacomb-like porous structure of the activated carbon. Granular activated carbon is typically used for this purpose. The water filtered by the Pressure Sand Filter enters the Activated Carbon Filter. Unlike in the case of the sand filter, trapped molecules in the carbon cannot be backwashed and got rid of. Hence, activated carbon in the filter has a finite capacity to adsorb and hold the pollutants, after which the carbon is said to be exhausted. The exhausted material is removed from the filter and disposed off: Fresh activated carbon is charged in the filter.
However, we recommend that the diameter of the activated carbon filter be selected to be 25% larger than the sand filter (SPF) to reduce the frequency of servicing.
Operation And Maintenance Considerations
Just as the PSF, the ACF also needs to be backwashed, albeit at a lesser frequency to dislodge any solid particles trapped by simple filtration action. When the carbon gets exhausted (indicated by no improvement in water quality across the ACF), fresh carbon needs to be filled into the filter
