Embodiment Construction

[0058] figure 1 The measured fluorescence induction curve 1 plotted over time is shown. The level of minimum fluorescence Fo is achieved when introducing a state in which virtually all primary electron acceptors are still oxidized, either by the dark state or by light sources using light with a wavelength greater than 700 nm. The photochemical reaction is activated by activating an intermittent or continuous light source at time point T1, resulting in the reduction of the original electron acceptor. The fluorescence level reaches a maximum fluorescence Fm when at least nearly all of the original electron acceptor is reduced. The time-wise fluorescence induction curve 1 after turning on the light source at time point T1 shows that the fluorescence increase from the minimum fluorescence Fo to the maximum fluorescence Fm does not occur suddenly, but increases continuously in a dynamic process, which should be attributed to Properties of living plankton cells.

Abstract

The invention relates to a method and an apparatus for detecting living phytoplankton cells and / or microorganisms in or out of water, particularly ballast water, bodies of water, sewage, or water in swimming and bathing devices. Said method is characterized by the following steps: - the variable fluorescence (Fv) is calculated by forming the difference between the maximum fluorescence (Fm) and the minimum fluorescence (Fo) in a measuring space or detecting part or all of the dynamic shape of a fluorescence induction curve in a measuring space, particularly measuring; and - calculating the number of living phytoplankton cells and / or microorganisms of a reference species in the measuring space in accordance with the variable fluorescence (Fv).

Description

technical field [0001] The present invention relates to a method and apparatus for detecting living (i.e. living) planktonic cells and / or microorganisms in / from water, especially at the surface of water, e.g. ponds , rivers, streams, lakes and impounded rivers, fresh and brackish water, ship ballast water, deep sea water, groundwater and trickle water, process water, industrial water, cooling water and circulating water, waste water, bath water and swimming pool water, Cultivation water and culture medium or production water. Background technique [0002] In the utilization of natural water, in order to make the water available for various purposes and to maintain treatment limits and discharge limits, an important goal in the water treatment process is to remove plankton and / or microorganisms. For example, a common problem concerns: breakthroughs in the growth of surface plankton populations and filtration systems, and the emergence of drinking water distribution networks....
