Many water districts in arid regions use a network of open canals to move water from a source–such as rivers or lakes–to needed agricultural and other areas. A common problem for these canal systems is the presence of zebra and quagga mussels. These invasive species are adaptable and proliferate quickly to foul equipment, clog pipes, and congest drains while increasing costs to hydropower plants and municipal water utilities.
A diluted solution of Sodium Hypochlorite (bleach) is introduced into the water stream at various points to combat the zebra and quagga mussels. The constant presence of bleach in the water at a low concentration is enough to thwart the growth of these invasive species.
Often positioned in remote areas, the Wanner Hydra-Cell M03/G13 pump with a polypropylene pump head and food-contact oil has proved to be a reliable dosing pump for this 24/7 duty. With its seal-less design and run-dry capability, there is minimal maintenance needed. More than 100 units are currently in service.
