| Abstract Scope |
Cellulose is abundantly available natural resource that can be utilized for a variety of industrial applications. Although cost effective to produce, a need has been identified by manufacturers to develop energy-efficient, dewatering of cellulosic nanomaterials, as cellulosic nanomaterials are not economical to ship long distances while containing significant water content (>95 wt.%). An electrochemical assisted sustainable and energy efficient dewatering technology is currently under development. Innovative reactor designs are utilized to demonstrate the feasibility of a cost-effective, industrially viable, and energy efficient ElectroDewatering approach capable of generating 20-30 wt.% final solids, that can be rehydrated under vortex and re-dispersed. Material properties (structure, particle size) were maintained by the dewatered cellulosic nanomaterials. Implementing sophisticated electric fields, energy use was reduced by 50% compared to conventional approaches at similar or higher dewatering performance. |
