zeovit chemistry

NO !!! The Zeolite Clinoptilolite will still adsorb ammonia in SW. And it has a greater affinity for NH4+ than Ca++ in SW. Go back to the RC link I gave and look. I / we posted lots on zeolites in SW, to include ammonia adsorption.



One of my replies

Clinoptilolite and heulandite are low field strength zeolites for which the cation specivities. The highest affinities are to the left, so Cs is adsorbed more than any of the others. And it makes no difference if it is FW or SW

Cs+ > Rb+ > NH4 + > K+ > Na+ > Li+ > H+, and Ba2+ > Sr2+ > Ca2+ > Mg2+ are predicted [11,
12]. Corresponding theoretical estimates yielded Ba2+ > Pb2+ > Cd2+ > Zn2+ > Cu2+ [16] butexperiments revealed Pb2+ ¡Ö Ba2+ >> Cu2+, Zn2+, Cd2+. Using clinoptilolite-Na as reference
NH4 + > Pb2+ > Na+ > Cd2+ > Cu2+ ≅ Zn2+ [14] and Pb2+ > NH4 + > Cu2+ ≅ Cd2+ > Zn2+ ≅ Co2+ >
Ni2+ > Hg2+ [15] has been determined.




Go look at these and read a few pages.

Thanks, Boomer.

I appolize I could not understand/digest your information.
Zeolite Clinoptilolite is the one for Zeovit system. From your information, people used not Zeolite Clinoptilolite for SW, so they had Ca adsorbtion problem.
