Induction time

Calcium sulfate dihydrate scale was electrochemically deposited from supersaturated solutions on gold electrodes (probe) of an electrochemical quartz crystal microbalance (QCM). From measurements of the induction period for the gypsum nucleation, the interfacial tension was calculated. The dependenc

This paper describes laboratory techniques for characterizing the permissible water recovery fraction in RO desalination, which is limited by the need to avoid scale deposition on the membrane. The CaSO4 scaling system was adopted for the development of these techniques. An upper water recovery boun
