Ceramic Filters  

Porous Ceramic Diffusers are used in various applications that include the following:

* Aquaculture Aeration

* Paper Industry ClO2 Plant

* Ozone Diffusion

* Waste Water Systems

* Ozone Diffusion

* Carbon Dioxide Injection

Diffusion is a reaction between gases and liquids and is used in numerous processes.

Bubble sizes are controlled by the volume of gas injected into the liquid and by the particular grade size of the Ceramic media used. Large bubbles react faster to the liquor surface; small bubbles create a large surface area for reaction purposes.

The efficiency of the Diffuser is of particular importance in both chemical and physical processes. The aeration of microbiological cultures is one critical area in which the efficient distribution of oxygen is of paramount concern.

H

 

Porcelain mullite

2. APPLICATIONS

* Permalith - Filtration of liquids and gases, air conveying and wastewater aeration.

Paper Industry ClO2 Plant.

* Genelith - Fluidised beds luminous bricks for radiant wall furnaces.

* Silicon Carbide - Filtration of hot gases.

* Hydralith - Geotechnology and aquaculture.

3. CHEMICAL PROPERTIES

Material SiO2(%) Al2O3(%) SiC(%) Trace(%)
Permalith 58 34 - 8
Genelith 54 40 - 6
Silicon Carbide 7 5 86 2
Hydralith 37 60 - 3

* Permalith & Genelith - Resistant against solutions of acids and weak alkalines

covering the complete neutral and alkali range up to pH12, with the exception of Hydrofluoric acid.

* Silicon Carbide - Resistant against acids with the exception of Hydrofluoric acid

.....and Organic solutions.

* Hydralith - High resistance to acids and alkalines.

4. TEMPERATURE RESISTANCE

* Permalith - Resistant up to 1000 °C, relatively insensitive to temperature shocks.

* Genelith - Resistant up to 1300 °C, high thermal shock resistance.

* Silicon Carbide - Resistant up to 1100 °C.

* Hydralith - Resistant up to 1400 °C.
