Bloemfontein Water (Bloemwater), the suppliers of potable water to the central and southern Free State, have taken delivery of two AlgaeTorches to augment their ability to rapidly and reliably determine the concentration of chlorophyll in their source waters.  In so doing, they have become the first Water Board in South Africa to take this proactive step.

At a presentation yesterday, World Water Day, attended by senior staffers, including CEO Dr B Malakoane and CFO Mr Ockert Stadler, the use of the instruments was explained to technical personnel by Dr Bill Harding of DH Environmental (DHEC).  DHEC are the South African agents for the bbe Moldaenke range of equipment.

Measurements of chlorophyll in water supplies provide an indication of the level of algae present.  Readers of Droplets will know that elevated levels of algae reflect excess pollution and possible water treatment and fitness for use issues for the water in question.  Until recently, field measurements of chlorophyll have been constrained by the time and cost required to obtain laboratory results.  Now, with the AlgaeTorch, readings can be obtained on-site in seconds.  Furthermore, the instrument also provides separate readings for total chlorophyll and the chlorophyll contained in blue-green algae (cyanobacteria), these being the algal group posing the biggest threat to the provision of safe water.  The ability to instantly obtain these values constitutes a major advance augmenting the ability of any water authority to monitoring of supplies.

The AlgaeTorch is but one of a range of sophisticated, state-of-the-art chlorophyll measuring tools from bbe Moldaenke.
