With this in mind, ceramic porous products manufacturer Fairey Industrial Ceramics has developed a new improved ceramic 7″ dome diffuser. The dome has been developed to fit on to standard 7″ uPVC baseplates/saddles and is primarily aimed at the dome retrofit market.
Oxygen transfer
Dome development has concentrated on achieving a product with a much more uniform bubble release than other domes on the market, thus achieving a better oxygen transfer efficiency and reducing the potential for Bio-fouling.
Recent independent SOTE testing by Thames Waters Process Dynamics group has shown the new FICL Ceramic Dome to achieve a clean water SOTE of 6.5%/m @ 2.0 nm/hr, compared to other dome diffusers tested under identical test conditions which achieved 6.0%/m (HDPE) and 6.2%/m (competitor Ceramic) respectively.
In addition to its use in wastewater treatment applications, a finer grade dome has been developed for clean water applications such as ozonation.
