AMG Ltd provides its clients with a complete professional installation service and turnkey solution for improving the water quality of reservoirs, lakes and fish farms.
AMG Ltd has extensive experience in the installation and commissioning of specialist aeration equipment and in particular the 'AQUAERATOR'. Our service includes detailed design, civil construction, mechanical and electrical installation and commissioning.
Thermal stratification occurs during the summer months, which can cause a number of problems in water bodies. The oxygenated, warmer water tends to overlay the colder denser water, which inhibits vertical mixing and in particular the downward transfer of dissolved oxygen.
The bottom waters become deoxygenated, with the possibility of the release of heavy metals from the bed sediment and the warm, well-lit surface layer will be conducive to the growth of large populations of phytoplankton.
If stratification can be controlled by artificial mixing, dissolved oxygen can be maintained at an acceptable level throughout the water column and algal growth is reduced as the phytoplankton are continually mixed through the water depth reducing the time spent in the Photic (well lit) zone, where growth is possible.
The 'AQUAERATOR' is a new device, which uses compressed air to promote mixing in water bodies subject to stratification. The bubbles reduce the bulk density of the water-air mixture, generating a vertical plume, which entrains the ambient near bed water, promoting vertical mixing and preventing thermal stratification."
For example the mixed air and water at the top of the draught tube is equivalent to 175 l/s; at 10m height the entrained mix is 4.5 tonnes/sec and at 20m height, the mixed air and water is 13.4 tonnes/sec.

AMG Ltd has been working on a number of recent projects. Research Projects. For example, aeration and m the Field Research was conducted in Wraysbury Reservoir, which is owned by Thames Water and Foix Reservoir managed by Agencia Catalunya de l’Agua. Both field trials were performed in April to October 2001 and 2002. The results of both of these field tests are recorded and commented upon in the H R Wallingford Report dated May 2003.

Since then, AMG Ltd has been busy with installing successfully installed three Aquaerator systems into Reservoirs in the UK. Primarily we have been focussing on Bristol Water PLC, which is actually very local to us. Thus it was particularly important for us to ensure that the installations and commissioning were completed quickly and competently.
