1:Name: fine/coarse bubble tube diffuser
2:Material: Quartz
The quartz diffusers are composed of pure quartz sand bonded with a glass binder to form a stable,mechanically strong porous element.Due to the exactly defined quartz grain size distribution and a well controlled production method,the quartz diffuser cylinders and discs have a remarkably homogeneous porous structure.
This results in a very uniform air distribution and bubble release.

4:Chemical Resistance:
Quartz diffusers are resistant up to pH 9.5 against municipal waste water as well as against waste water from industrial sewage water plants. The diffusers have a good chemical resistance against most solvents, hydro carbons and acids.

6:Applications:
The diffusers are mainly used for the aeration of waste water.
Fine bubble aeration Fine bubble aeration for activated sludge processes for nitrification and C- decomposition:
> municipal waste water treatment plants;
> industrial waste water treatment plants;
Coarse bubble aeration Coarse bubble aeration of waste water in grit chambers and mixing:
> waste water mixing avoiding sedimentation;
> homogenization of waste water feed;
Further applications possible.
