bath, in order to attain longer bath service life and reduce the chemical input. total of eight new detergent types are introduced, four of which largely cover the current application ran of CHCsolvents and cold cleaners, while the remaining four are intended for special cases.Tge detergent types were tested in industrial practice as alternatives to solvents and have been developed to such degree that they are ready for application. Thecomposition, mode of action and practical application of the new detergent types are pre- sented and compared with solvent degreasing. Aspects of bath maintenance and control, and the treatment and disposal of spent baths are discussed. Possible solutions are proposed for the problems which still remained unsolved at the end of the project. 2 Duration: 0 1 8 - 3 0 9 0 ZH8A8 Subject: Reduction of halogenated hydrocarbon emissions - Sub-Project.

Purpose of the project The goal of the project was considerably to reduce the consumption of halogenated hydrocar- bons by modifying production processesand designing environmentally friendly cleanin pro cesses The use of aqueous media is the rimary alternative cleaning process avalabli although this involves numerous roblems wfen, for example, different materials are cleaned simultaneously in the same instaration, the workpieces have
