BBE DAPHNIA TOXIMETER..
|
| The
Daphnia Toximeter continuously records and analyzes the movement
of daphnia in the instrument chamber where they are under
the influence of source or test water.
The instrument's toxicity computation is based upon the statistical
deviation of the various measured Daphnia behavioral parameters
from the (user-defined) norm. This unique instrument has no
counterpart in the world |

Application |
bbe
Toximeters provide a highly sensitive biological system for early
detection of potentially dangerous unknown substances, in a wide
variety of circumstances. These instruments are ideal for detecting
water quality contamination in real-time to protect both plant
and animal life. The Toximeters provide a means to detect (and
alert users to) potentially dangerous circumstances. Based on the
alert, the user may then take appropriate measures including further
chemical analysis, water source diversion, process suspension or
further treatment. Expensive chemical analysis can be targeted
to key toxic events with potentially significant cost savings.
Some examples of applications for our Toximeters include:
- environmental
monitoring, including ports, lakes, reservoirs and dams
- source/ground
water monitoring, supply monitoring and intake monitoring
- surface
water monitoring including rivers and lakes, measuring stations
and early warning systems
- pre-treatment
assessment
- post-treatment
quality control
