Abstract
The present invention provides water-soluble, extended-release chemical formulations, in tablet form, for urine pretreatment, that require minimal, if any, use of a binder component, yet are non-dusting, pliable, structurally strong, and not weakened by exposure to aqueous streams. The present invention also provides a simple and reliable method for controlled dispensing of such tableted formulations into a liquid stream that is particularly advantageous for use in micro-gravity environments, such as spacecraft urinal systems.
