Abstract
The present invention relates to a method for the purification of substrates, characterized in that the purification is carried out by at least one oxidation agent, selected from the group consisting of permanganate and ferrate (VI), and subsequently by a reduction agent. Organic residue, such as legionella or extracellular polymer substances (EPS) can be removed from surfaces of filtration or classification devices and from transport and storage devices utilizing said method. The use of oxidation agents further relates to the oxidation of extracellular polymer substances (EPS).
Claims13
A process for cleaning substrates wherein cleaning is carried out by at least one oxidising agent selected from the group consisting of permanganate and ferrate (VI), and subsequently by a reducing agent, wherein:
- the oxidising agent is in the form of an alkaline solution and the dissolved oxidising agent has a percentage by mass of 0.002 to 0.1 mass-% in the alkaline solution;
- and the substrate comprises organic material, wherein the organic material comprises aggregates, components, excretions, or decomposition products of microorganisms.
