It still is not possible to use the traditional chemical analyses alone to get a
complete view of the water quality.

The most important reasons why to use On-line biomonitoring systems are:

1. Traditional analyses are only possible for a  small number of the dangerous    chemical substances, even with the latest highly sophisticated instruments.
2. It is estimated that only about 5% of the existing toxic chemicals in water can be analysed by on-line monitors.
3. Concentrations of many products are lower then the detection limits.
4. Results of traditional, chemical analyses give no information regarding the    toxicity of the combined effects of mixtures.

Toxicity monitoring with Luminescence bacteria

This completely automated Biomonitoring System uses freshly cultivated light emitting bacteria (Vibrio fischeri) as a biological sensor. The luminescence is measured before and after exposure to calculate the inhibition in %.
The luminescent bacteria test is an automated version of the ISO 11348 allowing continuous monitoring of rivers, drinking water production or wastewater treatment plants.

Advantages of the TOXcontrol:

• Easy to operate, user-friendly and very robust.
• Quick response time to a wide range of contaminants.
• Very reliable, low running & maintenance cost.
• Automatic cultivation of bacteria in the TOXbioshaker.
• TOXview software for data acquisition & evaluation.
• Can be used with in-line dechlorination.
• Optional uv-vis sensor (TOX-s::can) for TOC, BOD, turbidity, SAC254, NO3-N
