Abstract:
A method for assembling an electrodeionization device comprising providing in a sequential arrangement: an anode, membrane cell assembly, cathode; wherein the membrane cell assembly comprises at least one sequential arrangement of: a cation exchange membrane, concentrating chamber, anion exchange membrane, diluting chamber, cation exchange membrane, concentrating chamber and anion exchange membrane. The method includes locating an ion exchange spacer in at least one chamber of the membrane cell assembly wherein an ion exchange spacer comprises an ion exchange resin and a dissolvable binder.
A 2017 study led by the Nature Conservancys senior marine scientist, Mark Spalding, estimated that coral reefs are worth $36billion annually to tourism industries in key tropical coastal regions such as Florida and Hawaii, the Queensland coast in Australia and the coast of Kenya on the Indian Ocea
"At their core, reefs are about people as well as nature: ensuring stable food supplies, promoting recovery from coral bleaching, and acting as a magnet for tourist dollars," said Mark Spalding, senior marine scientist at the Nature Conservancy and a lead author of the report."We need apply the kn
