Fine-bubble aeration membrane - compact and universal due to its high oxygenation efficiency and long lifetime in the aeration process.


Manual for aeration membrane ECO-68


Benefits of the aeration membrane:


> regular and continuous bubble production all over whole aerator length (up to 30m)
> no liquid is leaking in after operation stop or membrane choking
> minimal pressure lost
> optimized shape, density and size of perforation
> high rigidity
> long lifetime (in common wastewater up to 12 years)
> optimal wall thickness ensuring high mechanical endurance
> excellent chemical resistance
> membrane enables automatic condensation drain off


Aeration membrane - applications:

> building of the new water treatment plants
> reconstruction and intensification of the existing water treatments plants
> intensification of the fish ponds
> aeration of the water streams and pools
> mixture of the galvanic baths and the neutralization pools
> agitation of the suspenses
> biodegradation of the oil sludges
> biotechnology...
