Regenerable Mixed Bed Deionization
Systems--Design and Operation
Figure 4 shows System C, which uses RO as the primary deionization
technique similar to System B, but EDI polishing in lieu of off-site regenerated IX.
Solar powered desalination of hyper saline ground water; solar powered capacitive deionization
desalinating brackish water; use of geothermal energy for brackish water desalination, etc.
ENPAR's patented DesEL technology utilizes the principle of capacitive deionization
to treat drinking water and waste water.
part 5 - water treatment plant - distiller, deionization
unit part 6 - laboratory vacuum pump,
Emerging technologies that would contribute to portable water purification such as capacitive deionization
and membrane distillation are entering the market.

For industrial process and boiler water, applications include deionization
, the removal of sodium, hardness, barium, chlorides, sulfates, alkalinity and silica.
Looking at several new concepts or variations on existing concepts, we see hybrid desalting plants that combine desalting processes, more efficient control systems, reverse osmosis/power plant cogeneration, improved pre-treatment, use of alternative energy sources, ongoing membrane development and the commercialization of new processes such as capacitive deionization
have potential for advancing desalting technology.
