Specifications

material:quartz sands;
The diffusers are mainly used for the aeration of waste water.

 

 

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.
