Removal of Dissolved Gases


The Dreamtime PCR technology allows the selective removal of gases from water. This is an ambient temperature, ambient pressure process that simultaneously removes the gas and converts it to a non-volatile species. The most common applications are ammonia and oxygen removal. However, all gases other than hydrogen, nitrogen and the noble gases can be removed by this process. Selected examples of PCR applications are presented here.


Removal of ammonia from waste water streams in the mining industry
Removal of ammonia in the food industry
Removal of dissolved oxygen from boiler feed water for corrosion prevention in power stations
Removal of dissolved oxygen from beverages for oxidation stability
Low Alcohol Wine Production



Production of High Quality Liquid Food & Pharmaceutical Concentrates


The Dreamtime Concentrate Production Process is a membrane-based process designed primarily for the concentration of liquid foods such as fruit and vegetable juices (orange, grape, apple, strawberry, carrot and others), dairy products (milk, whey) and food extracts (tea, coffee). This process may also be used for the concentration of pharmaceutical products that lose potency when heated. Unlike conventional concentration processes namely multi-stage flash distillation (MSF), multiple effect distillation (MED), vapour compression distillation (VCD), freeze concentration (FC) and reverse osmosis (RO) the Dreamtime process has all of the following characteristics.


Concentration to higher levels (typically 70 °Brix) than achievable by other processes
Elimination of heat degradation during concentration
Minimal loss of delicate aroma and flavour components
Theoretical 100 % retention of non-volatile solutes


The Dreamtime Concentration Process may also be used in conjunction with other membrane processes such as microfiltration, ultrafiltration, nanofiltration or reverse osmosis to effect any desired separation.
