METHOD OF CLEANING CONTAMINANTS FROM A MULTI-LAYERED MESH FILTER

摘要

A method of cleaning contaminants from a multi-layered mesh filter. A first step involves immersing the filter in a chemical presoak tank containing a chemical cleaning agent effective with the contaminants. The chemical presoak tank is maintained at a temperature of not less than 160 degrees fahrenheit and not more than 180 degrees fahrenheit. The filter is maintained in the presoak tank for a time duration sufficient to soften the contaminants without causing the contaminants to break down into layers of constituent elements, while raising the temperature of the filter in preparation for cleaning. A second step involves immersing the filter in a cleaning tank containing hot water maintained at a temperature of not less than 160 degrees fahrenheit and not more than 180 degrees fahrenheit and subjecting the hot water in the cleaning tank to ultrasonic waves at a frequency of not less than 80 megahertz and not more than 120 megahertz.
