Blue revolution*
Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief focuses on ways to improve the use of water. It deals specifically with advances in water treatment in the manufacturing industry. In terms of the Atlas of Technological Megatrends it is concerned with the functionality of matter processing.
In recent years a clearer picture has emerged of the cost of water to industry. A Canadian study suggests the following cost profile: Acquisition, about 50% of total cost; Discharge treatment, about 30%; Intake treatment, just over 10%; Recirculation, also about 10%. [Statistics Canada, 2007, EnviroStats, Vol. 1, No, 2, "The cost of water in the manufacturing sector," catalogue number 16-002-XWE.]
The high cost of water treatment is encouraging innovators to focus on improvements in treatment technologies. There are three broad classes:
  • Physical - e.g., filtration
  • Chemical - e.g., ozone treatment
  • Biological - e.g., bacterial treatment
Technology executives and investment professionals should note the impact of new technologies on this profile.
In the physical area, nano-technology enables ultra fine filters. These allow very large flow throughputs and permit separation at molecular level. Chemical processes like ozone treatment reduce the use of chemicals, save water and reduce processing times. Note the potential for nano-tech filters to compete with traditional chemical separation. In the case of biological processes, newly discovered organisms serve as purifying agents, while genetic exploration yields DNA that can be used to improve these agents.
*The theme "Blue revolution" is taken from "Solutions for a Water-Short World", Population Reports, Johns Hopkins University, Vol. XXVI, No. 1, September, 1998.
