PCBA Cleaning - Activated Carbon

We use activated carbon and mixbed in the washing machine. We have noticed that the conductivity values ​​of the regenerated activated carbons we received from the service provider have been high recently, which consumes the life of the mixbed very quickly. Afterwards, we did some experiments ourselves. Basically, there are two types of activated carbon on the market, coal-based and coconate-based. The conductivity levels of coal-based ones are very high, and we got good results when we used coconate-based. What is your experience on this matter? Coal-based is better at retaining organic dirt, but there is a conductivity problem. Is coconate-based activated carbon used in this process? What are the differences?
