methods

We use four methods to investigate the various aspects of water quality:
– purity: microbial / chemical analysis;
– flow dynamics: drop picture method;
– influence on organisms: growth and vitality studies on freshwater algae;
– influence on humans: extended sensory analysis.

Microbiological / chemical analysis
The microbiological / chemical examination is used to determine the possible presence of bacteria (total number, coliforms and enterococci) as well as important chemical-physical parameters such as hardness and nitrate content or pH value. This allows changes in water quality and possible changes due to treatments or other influences to be documented.

Examination of flow dynamics (drop picture method)
Flow characteristics allow a statement about an important positive quality aspect of water, but do not provide an analytical determination of the chemical constituents dissolved in water. The drop picture method is a diagnostic tool for supplementary water analysis using flow physics. Its images reveal the water’s response to the complex systemic interaction of its inner factors and components. In this method falling drops of distilled water excite motion in a thin horizontal layer of the water sample mixed with 13 per cent pure glycerine, under standardized conditions. The flow patterns that arise through instabilities are made visible and documented. The formative potential revealed in the flowing water is regarded as a quality aspect in its own right.
See drop picture method for a description of our conditions of analysis.

Algae analysis
Today, algae are used as indicators of water quality in toxicology and, to a minor extend in drinking water management. As a supplement to chemical-analytical test methods, living organisms show an overall picture of the effect of a water sample. At the Institute of Flow Sciences, water tests complying toxicity standards are carried out with algae that have been expanded to show not only toxic conditions but also more slight influences. Thus, in addition to conventional growth parameters, changes in morphology as well as in reproduction cycle are also used for assessment, whereby even weak influences of water quality can be detected.

Extended sensory analysis
This method developed by Dorian Schmidt uses our awake directed attention by a deeped consciousness and intensified perception, to perceive forces and life processes in nature and human beings which we experience continuously but unconsciously through our life force organisation. Through intensive training over many years, it is then possible to objectively perceive and explore the active, formative forces of life in an appropriate way.
