How Do You Keep Your Water Clean?
The smartest way to the keep water clean is to install a Vortex Filter.
Not only does is remove 95% of sediment and debris, but it also aerates the water. Aerated water keeps the walls of the tank healthy, therefore reduces the chance of any harmful bacteria growing.
The filter works by fitting it to a horizontal drain pipe, it filters and diverts the rainwater to a storage tank. The incoming rainwater runs out of the horizontal drain pipe into the side of the filter and is then led in a vortex to the filter housing below. There the rainwater is drawn through the vertically placed fine filter by adhesion and is directed through the outlet to the storage area, while the debris is rinsed away with the remaining water to drain.
- Filtering to 0.44 mm all by gravity.
- Withstands up to 30-tonne vehicles.
- Extension risers available for deeper underground installation.
