Mahlobo unveils Vortex Settling Basin to boost water quality in Nkandla

Deputy Minister of Water and Sanitation, David Mahlobo, has commended the Water Research Commission (WRC) for its continued investment in innovative technologies to tackle South Africa’s water challenges, following the launch of the Vortex Settling Basin (VSB).

Mahlobo explained that the VSB is an advanced water treatment system that employs vortex flow technology to remove sediments, suspended solids, and pollutants from water.

The system operates on the principle of centrifugal force, which enables heavier particles to settle at the bottom of the basin, while cleaner water is discharged from the top.

Through its vortex action, the VSB forms a cone-shaped sediment deposit, allowing for efficient separation.

The settled particles are then removed by gravity, while the clarified water exits via a discharge weir.

“The VSB effectively removes heavy sediment particles through its vortex action, causing the sediments to settle in a cone shape. These particles can then
