Dissolved Oxygen

The levels of dissolved oxygen (DO) present in lakes and a stream is commonly used as

an indicator of water quality. Maintaining adequate concentrations of DO is vitally

important for supporting fish, invertebrates and other aquatic life.

Companies that discharge nutrient rich substances can have a major impact on the DO

level therefore the monitoring and control of discharges is critical. Similarly, spills of

substances such as milk and liquid or powdered foodstuffs can have a massive impact on

the DO in a body of water.

An economic alternative to fitting motorised penstock valves is to use either the

DrainstopperTMor FlapstopperTM in conjunction with a spilt produce detector such as a

Turbidity Sensors in the plant and a DO monitor located strategically in the body of water.
