ABSTRACT:
Disclosed is an apparatus which has the capability of cleaning a waste or used filter assembly with a broad spectrum of chemical agents in an automated fashion. The cleaning apparatus comprises a cleaner vessel for accommodating the filter assembly to carry out triethylene glycol cleaning, sodium hydroxide cleaning, nitric acid cleaning and water washing in a predetermined cleaning sequence. First to fourth reservoirs communicate with the cleaner vessel through their corresponding pipelines to feed such chemical detergent liquids as triethylene glycol solution, sodium hydroxide solution, nitric acid solution and pure water into the vessel. The detergent liquids will circulate within the cleaning vessel by means of a stream generator, whereby the filter assembly can be cleaned to a higher degree of detergency.
