Activated Carbon FAQs
What type of activated carbon should I use for water treatment?
The correct activated carbon depends on the application, water source, target contaminant, flow rate, vessel size and required contact time. Granular activated carbon is commonly used for dechlorination, taste and odour reduction, organic removal and pretreatment before RO or other downstream equipment.
How much activated carbon do I need?
The required carbon volume depends on vessel size, service flow rate, empty bed contact time and contaminant loading. Undersized carbon beds may cause early breakthrough, poor chlorine removal or insufficient organic reduction. If you are unsure, Crystwater can help estimate the required media volume.
When should activated carbon be replaced?
Activated carbon should be replaced when chlorine, taste, odour or organic breakthrough occurs, or when pressure drop, fouling or operating history indicates the media is exhausted. Replacement frequency depends on feed water quality, flow rate, contaminant loading and total treated water volume.
What is the difference between granular activated carbon and carbon block filters?
Granular activated carbon is typically used as loose media in refillable vessels, tanks or larger filtration systems, while carbon block filters are formed cartridges commonly used in housings. The best option depends on flow rate, contact time, installation type and replacement method.
