per minute or cfm and using a dehumidifier or air scrubbing equipment the high moisture content in the enclosed space which would otherwise be generated by high pressure water blasting can be reduced to levels sufficient for primers and paints to be applied and adhesion guaranteed the conditions inside of a tank will be different in every instance outside temperature inside temperature tank size and humidity levels will all have an effect on the amount of moisture produced inside of the tank this will dictate what combination of equipment will be used but the overall process remains the same in the particular context described herein preliminary steps prior to implementing the inventive process include setting up a system of scaffolding that will allow a seamless flow for the operators of the cleaning and painting equipment additionally airlines electrical cables and explosion proof lighting are run into the tank the hoses for the water blasting will be routed as will the vacuum hoses for the removal of water and debris in some cases it may be necessary to create an opening in the tank by cutting out a portion of its wall the tank 39 s size and shape along with the size and location of its vents exits or other openings will be used to gauge the amount of airflow that will be required and air moisture will be measured before and during the blasting to determine which size of dehumidifier.
