Innovation breathes new air into fish farms11 February, 2014 –

AQUARIUS Marine Group has announced a new version of its water aeration and mixing solution.

Called the Aquaerator, this innovative, patented technology is designed to improve the health and oxygenation of reservoirs, lakes and fish farms.

It will also satisfy water quality maintenance in compliance with the 2015 Water Framework Directive and reduces long term water maintenance costs.

The device also provides a long term, low carbon solution to thermal stratification – a common issue for fish farms, which leads to poor oxygenation and a build-up of metals in suspension – and blue green algae.

The Aquaerator utilises a UPVC manifold, instead of stainless steel – which attracts manganese oxide, and is designed to provide a virtually maintenance-free solution for resolving anoxic conditions.

The detachable UPVC manifold tubes can also, if necessary, be replaced easily by divers without the need to lift the Aquaerator from the bed.

The sub-surface solution sits on plinths above the silt layer and works by mixing air with water from the bed to form a rotating plume of fine bubbles, which mix and circulate the layers of water.

Unlike other solutions, the Aquaerator is designed to draw water horizontally from the surrounding base layer to ensure minimal disruption of the surrounding ecology, and that silt is not drawn up into the water column.
