Bolina floating boom against water weeds at Water-Link


A Bolina Permanent Debris Boom was installed at Water-Link in Belgium to stop water weeds from contaminating the water supply.

Water-Link supplies drinking water in northern Belgium, using natural water resources around Lier and Duffel to produce potable water for Greater Antwerp, Belgium.

Problems with the excessive growth of water weeds occur every year in the large storage basins. Water weeds do provide oxygen in the water, but this invasive species, which grows very fast and floats on the water surface, clogs the waterways and drainage grids. Water weeds also clog the water flow between the different basins. It is a very labour-intensive task to keep the grids free in the summertime, so that the water supply for the drinking water process is not compromised.

By placing Bolina’s permanent floating debris boom PDB-600 a couple of metres in front of this water supply, the water weeds are stopped even before they reach the dirt grid. The removal of the water weeds is now also very quick, as there is no longer any manual work needed at the narrow grating.

An excavator with sorting bucket scrapes all the water weeds along the wall of the Bolina debris boom towards itself and then places it directly into a container. And because the floating debris boom is placed at an angle of 45°, the flow in combination with the smooth sides ensures that the water weeds are automatically turned towards the bank.

Currently only the first reservoir in Lier is equipped with the Bolina buoyant screen, but there are plans to equip the other basins with similar barriers in 2021.
