The underlying technology uses totally biological treatment processes, in which micro-organisms convert organic matter into water and gas that can be used as an energy source for heating or electricity. The result is an efficient treatment for highly polluted effluents, such as the wastewater discharge from polluting industries: pulp and paper, food and beverage, all of which have to cope with emerging regulations regarding water and waste recycling.
A new technology out of two old ones
"The main challenge we faced while developing DANA was to combine two systems an anaerobic and an aerobic in one appliance", says Tamar Arbel, CTO in AQWISE. Udi Leshem, who is the vice president of business development in AQWISE, comments: "Wastewater systems are like a human resources company they combine the right bacterium with the right task. Usually there are either anaerobic or aerobic bacteria for each task, the uniqueness of DANA is that it offers both".
Leshem refers to the fact that the two prevalent methods for performing biological treatment processes are either aerobic or anaerobic. An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It could possibly react negatively and may even die if oxygen is present.
The anaerobic process is a complex one with high operation and maintenance costs and with a need for professional manpower. The aerobic systems, on the other hand, are fast and easy to maintain, but fail to handle large quantities of industrial wastewater. DANA combines both technologies within a single low cost hybrid system. Therefore, it enables clients to deploy a wastewater system capable of treating industrial wastewater with a smaller environmental footprint and lower costs.
