Conditioning of super-concentrate brines from industrial water recycling for salt recovery
Tobias Hogen | Technische Universität Berlin | Germany
The raising amount of brines from industrial water recycling is an emerging ecologic and economic risk. Within the research project "HighCon" processes are developed to increase water yield and reduce brine disposal by inorganic salt recovery. The preprocessed brines (called "super-concentrate brines") must be specifically conditioned to allow subsequent selective crystallization.
Experimental Results on Brine Treatment with Special Configuration of Membrane Distillation
Vinay Narayan Hegde | Fraunhofer ISE | Germany
In this study, the experimental results on new membrane distillation configuration called Feed Gap Air Gap Membrane distillation (FGAGMD) will be presented. The experimental solution used for the setup is brine from RO brackish water, industrial waste water from cosmetic industries etc. in the range of lower concentration. The output is expected to be saturated or nearly saturated solution.
Concentration of reverse osmosis concentrate from incineration leachate using membrane distillation coupled with a pre-treatment process
Dr. Jinyu Shi | China
The reverse osmosis concentrate (ROC) from municipal solid waste incineration plants was effectively concentrated 20 times by direct contact membrane distillation coupled with chemical precipitation pre-treatment process. During this process, the amount of permeate accounted for 95% of the ROC volume was obtained, which can be used directly for in-plant circulating cooling system.
Transformation of organic matters in reverse osmosis concentrate from a municipal wastewater reclamation plant
Zibin Xu | Tsinghua University | China
Treatment for reverse osmosis (RO) concentrate is a problem in RO process operation. This study found that ozone can remove COD, UV absorbance and fluorophore effectively, and transformation of organic matters in RO concentrate was also investigated, demonstrating that ozonation was a potable way to deal with organic matters in municipal wastewater ROC.
