We manufacture sand separation units for round basins. The basins are made of concrete or steel. Water containing sand or other heavy solid particles is led to the centre of the basin to slow down the flow, allowing the heavy particles to settle to the bottom of the basin.

If the bottom of the basin is constructed as a cone of steep slope, sand is pumped out from the bottom of the basin for further treatment. If the bottom of the basin is constructed as a cone of gentle slope, sand is scraped into the drain at the bottom and then pumped out for further treatment. A surface sludge separation unit can also be installed in a round basin. Water is led out of the basin as overflow to the next part of the treatment process.
