Resource Recovery from Waste, Water and Wastewaters with Membrane Technologies
Abstract
In this study, critical elements (Boron (B) and Rare Earth Elements (REE)) recovery is
studied with membrane technologies. Concentrated boron can be recovered by using
different technologies. Membrane technologies such as reverse osmosis have a potential
to concentrate the boron. pH of the solution is very important if reverse osmosis is
applied. Removal of boron at pH levels of 7 and 10 increases from 80% to 97% with
reverse osmosis membranes. Another critical element is rare earth elements in the World.
Rare earth elements (REE) is a group of elements that involve lanthanides, scandium and
yttrium. A successful REE transport for wastewater was observed compared with the
concentrate flow of the acidic waste slime.
