Control Algae in Drinking Water
Can Coptrol be used in drinking water storage’s and tanks?
Yes. Coptrol is highly effective and proven method of eliminating blue green algae in potable water supplies.
Is Coptrol approved for use in Drinking water storage’s and tanks?
Coptrol is approved by the APVMA (Australian Pesticides and Veterinary Medicines Authority) for application in potable water (water suitable for drinking) reg no. 31030 and can be sprayed, dripped or flown onto waterways to treat blue green algae.
What species of algae are most important to control in drinking water storage’s?
The most important group of algae affecting potable water supplies are those described as blue greens.
There are a number of species of blue green algae and many of them produce highly toxic compounds that directly target either the liver or central nervous system. In their purified form these toxins are more potent than either arsenic or cynanide.
|When a potable water storage system is contaminated by blue green algae it is important to minimise algal cell growth as algae cell population is directly linked to toxic concentration. Large blooms invariably lead to higher levels of toxin in the water.|
Early algae treatment is best
We recommend early treatment as this strategy ensures large numbers of toxin producing blue green algal cells can be prevented from developing into a bloom, it also ensures the most cost effective use of Coptrol.
|If algae is a problem in your drinking water supply follow this method to keep your waters clear and free of Algae.|
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. 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:
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.
