"The effect of GRANDER water revitalisation couldn't be explained by any of the questioned natural scientists, but the positive effects are definitely noticeable.  The expectations were fulfilled and in most cases exceeded."

"We recommend the use of GRANDER water revitalisation in industrial companies," as could be read in a summary report written by B.A.U.M.

At the Institute for Innovation and Environmental Management at the Karl Franzen University in Graz, University professor Dr. Stefan Vorbach assigned a thesis to Katrin Zunkovic with the title "Wasserbelebung am Beispiel Grander-Technologie - Eine empirische Erhebung unter industriellen Anwendern? Grander Technology as an Example of Water Revitalisation ? an Empirical Survey among Industrial Users.

Thirty-two industrial companies were examined in Austria, Germany and Switzerland. The effects of water revitalisation were analyzed by means of a questionnaire. Asked in this questionnaire was the type of use (cooling systems, production...), economic benefits, measurable effects and the main question: ?Can Grander water revitalisation make a contribution in industry to effective water management, i.e. to the environment or not??

· 48 % of the companies responding to the questionnaire assessed the question of effectiveness at "very good" and 47 % at "good".

· Of those questioned, 90% assessed their satisfaction level at "very good" or "good".

· 71 % of those questioned had actively measured an economic advantage.
