Scottish Water has purchased three Aquaerator aeration and mixing systems from Aquarius Marine Group (AMG), specialists in lake aeration, to improve water quality in Aberdeenshire’s Craighead Reservoir.
The new Aquaerator technology, developed and installed by AMG, will help combat thermal stratification and increased levels of iron and manganese, a common issue for reservoirs and lakes during the summer months. Scottish Water expects to see water treatment cost reductions and less dependence on expensive chemical interventions at the local water treatment works.
Selecting the solution from AMG will provide Scottish Water with a more environmentally sound and cost effective solution to water quality and oxygenation. Scientifically proven, the Aquaerators work by mixing air and water horizontally just above the bed of the reservoir, above the silt layer, to form a powerful rotating plume. The bubbles aerate and mix the de-oxygenated bottom waters to introduce oxygen and return metals and manganese held in suspension to the silt at the bottom.
