The product – the 'AQUAERATOR'
Quotation from H R Wallingford REPORT EX 4808, May 2003,

"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.

Our Gallery page provides further information on the report written by H R Wallingford, technical information, recent projects and sampling data. Installations of the 'AQUAERATOR' are undertaken by our dedicated team of professionals, who are all working towards CSCS membership and other qualifications"
