Title: Treating waste water using aluminium oxide - doped or surface treated with cations or anions (SW 8.1.79)
Inventor: DONNERT DIETFRIED DIPL ING DR
IPC: B01J20/08
Filed: 1978-05-05
Abstract: The process comprises using either (a) an Al oxide doped during its prepn. with cations or anions which can be incorporated into the crystalline network and which retard crystallisation of the Y phase of the Al2O3 or (b) an Al2O3 the surface of which is treated after its prepn. with >=1 salt of these ions. The process may be applied to the elimination of difficulty biodegradable organic substances. It overcomes a previous difficulty that Al2O3 had a very weak absorption power for neutral and basic substances. It enables wide application of the process and results in a large interior surface (e.g. 230 m2/gm cf 80 m2/gm) with stabilisation resulting in better absorption properties. It is cheaper than active carbon.
