Development of water capsules. Final report.
Spokane, WA: U.S. Department of the Interior, Bureau of Mines, OFR 45-79, 1978 Jan; :1-43
The objective of this project was the experimental investigation of water capsule production using a submerged nozzle encapsulation apparatus. Initial efforts on the project involved nozzle configuration and shell formulation was modified to obtain the best balance of capsule breakage resistance and water retention. Subsequent effort centered on determining operating conditions that would produce the best quality capsules for each candidate shell formulation as determined by laboratory tests. The major emphasis concerned scale-up studies of capsule production capacity and the treatment of problems associated with grouting cartridge fabrication.
