Development of an Effective and Economical Carbon Dioxide Snow Cleaning Process for Heavily Soiled Surfaces in Commercial and Industrial Areas in Order to Improve the Profitability of Small and Medium Sized Building Cleaning Services
AiF 13464 N
In many industrial and commercial areas, production-, maintenance- and repairing plants as well as certain parts of buildings must be cleaned at regular intervals due to high amounts of dirt coming up. This is a pre-condition for the guarantee of safety and product quality.
Currently aqueous cleaning processes (e.g. high-pressure systems) are often used. These methods lead to high amounts of waste water which have to be treated expensively due to the high concentrations of hazardous substances. Waste water free cleaning procedures are therefore a possible solution. An example of such a process is cleaning by dry-ice-blasting with CO2-pellets, which, however, is very costly. By contrast, the cleaning with CO2-snow generated from liquid CO2 is much cheaper in principle. This technique, however, has not yet been applied for the cleaning of hard surfaces in industrial and commercial areas. The aim of the project was the development of an economical, gentle and waste water free cleaning process with high cleaning efficiency.
