silica is used to manufacture zeolite

There is much debate between which is better. In almost every case, a zeolite powder or zeolite capsule will contain more zeolite than any liquid but that isn't the only important factor.

It is believed that liquid zeolite's are more rapidly absorbed by the body and also contain carriers such as fulvic/humic acids, trace minerals, among others. These carriers help bring the zeolites in deeper.

Generally zeolite powder products don't have carriers, some that do are Super Z Lite Capsules and ZeoPowder.

It's probably best to take both zeolite powder and liquid zeolite to ensure maximum zeolite dosage and absorption (from the carriers in the liquid zeolite).

there is no difference between zeolite process and permutit process. permutit means sodium aluminum zeolite (Na2Al2Si2O8 )

Yes, zeolite can be cleaned and reused. It can be cleaned with a saltwater solution, and then it can be used again.
