The Bio-Sensor® is a highly efficient and cost effective means to continuously monitor water quality. Rapid response time and automated decision making ability can help insure the safety of drinking water supplies or prevent the discharge of toxics into the environment. The Bio-Sensor® automatically and continuously monitors the quality of drinking water, industrial and municipal effluents, and other water supplies. Originally designed and developed by Biological Monitoring, Inc. it combines living organisms, acting as sensors, with advanced computer and electronic technologies.

What These Fish Know Can Hurt You!

Employing fish sensors, the Bio- Sensor® detects the presence of a broad range of toxic substances. Changes in ventilatory behavior and certain locomotor activities are detected immediately through noninvasive electronic sensors in each tank.

Fish signals are amplified, filtered, and interfaced to a computer through the Bio-Amp®. Computer based algorithms continuously monitor and assess each fish’s reaction to the water. When a significant number of fish respond simultaneously in an abnormal manner, an alarm is initiated.

Easy to Learn - Easy to Use

Custom designed computer software uses a menu oriented approach for ease of operation. Procedures for operation and maintenance are easily learned. Users report quick start-up with minimum training and expense.

Operational and Research Models Available

The 7000 Series Bio-Sensor® is the seventh generation of the original water quality monitor developed by Biological Monitoring, Inc. For operational use the Model 7008 features eight fish (on independent sensor channels) monitoring a single water source. This model is typically employed on-line in drinking water systems at the raw water intake and at strategic points in the distribution system*.

*Distribution system requires optional de-chlorination unit

How it Works
  1. Water continually flows from the monitored source through fish sensor tanks in the unit.
  2. Bioelectric signals from the fish are filtered and amplified in the Bio-Amp® before being sent to the computer for analysis.
  3. The computer analyzes each fish’s ventilatory activity to determine if it is acting abnormally.
  4. If a significant number of the fish are determined to be acting abnormally at the same time an alarm is triggered and a water sample is collected for analysis.
  5. The ventilatory activity of the fish can be seen on the display screen as a series of waveforms.

Concepts

  • Real-time monitoring results in fast detection of toxicants at sublethal levels.
  • Sensors provide early warning to trigger need for investigation.
  • Fish are the best sensors of their natural environment.
  • Based on science of a high toxic response relation between fish and humans.

Features

  • Easy set-up and use. Does not require special technical skills.
  • Remote communications and viewing of activity.
  • Choice of fish species available at most local aquarium stores.
  • Automated fish feeders minimize maintenance requirements.
  • Integrates with physicochemical monitors to assist in analysis.
  • Can trigger stand alone alerts or tie into existing SCADA system.
  • Automated water sampling when an alert condition is detected.

Operation

  • Locate units at the raw water intake and at key points in the distribution system.
  • Rugged construction; the unit can be set up virtually anywhere there is a shelter, water supply line, drain and AC power.

Advantages

  • A cost effective first line measure.
  • Continuous monitoring early alert to toxic presence water source.
  • Alarms facilitate rapid response before there is public harm.
  • Can be employed, monitored maintained by non-skilled technicians. Increases public confidence drinking water safety.

Computer Generated Alarms

When an alarm is triggered the computer is capable of initiating any number of specialized routines depending on the application. The signals may be interfaced with SCADA systems or simple telephone message generating devices.
