How to Control Algae in Mining and Power Stations

Algae block screens and filters |pumping equipment|blockages|

Mining operations and power stations use, store and re-use water. Blockages to screens and filters in pumping equipment pose a real threat and increased costs.

Algae increase pumping costs |increased energy costs|water flow

The presence of algae in the stored water creates additional friction which translates into increased energy costs in pumping. Experiments with algae fouled water have recorded as much as a 10% water flow reduction. When filamentous algae are present in the stored water the reduction of water flow is even higher.

Algae prevention is possible | anticipated bloom|onset hot weather|

It is possible to prevent algae blooms by applying algae prior to an anticipated bloom. e.g. onset of hot weather. Coptrol remains active in the stored water until an algae bloom occurs and then goes to work killing the bloom thus saving increased energy costs.
If algae is a problem in your water source follow this 5 step method to keep your waters clear and bright.

 1.  First identify the algae present. Please use our guide here for more information. This page explains common algae within Australia.

2.  Now calculate the volume of water to treat. Ignore depths below 1 metre. Please refer to our “Quantities” page to calculate the amount of water to treat.

3. Next calculate the amount of Coptrol needed. An easy way to calculate is:

• If the algae is fine and free floating use 2 mL of Coptrol per 1000 Litres (1 cubic metre) of water. That is equivalent to 2 Litres of Coptrol per 1000 square metres of surface area.

• If the algae is long and stringy use 5 mL per 1000 litres of water (1 cubic metre) or 5 Litres per 1000 square metres of surface area.

4. Dilute the required amount of Coptrol using a 1:10 or even a 1:20 Coptrol water dilution.

5. The best application method is by spraying. Apply on a sunlit wind free day when algae first appear. If this is impractical, please refer to our “Application” page on how to apply Coptrol.
