ball valve 22 a and 22 p to the air distributors 2 and 3 shown in fig1 located at the front and rear end of the device subsequently connecting the isobaric feeding to the air general feeding 1 indicated in fig1 2 a and 2 b once all the quasi isobaric air feeding net is mounted on the removable insulating structure to position anodes and cathodes indicated in fig6 and also partially shown in fig5 all the set is installed inside the masonry electrolytic cell 10 once the above is done the air entrance to the fan of the plant that supplies the bubbling gas was connected then 61 insoluble anodes and 60 stainless steel cathodes spaced at 100 mm between cathodes centers this number is fixed by the distance between the cathodes guides positions 9 of the removable insulating structure to position anodes and cathodes then the cell was filled with electrolyte and was connected to the electric power to deposit metal on the cathodes thereby starting the feeding of electrolyte and bubbling gas the operating conditions were set at 2 volts between anodes and cathodes and electrolyte circulation at 30 m hour and bubbling gas feeding at 15 cubic meters per hour then the microporous hoses was damaged 5 2 breaking it followed by the closing of the stopcocks 22 a 2 and 22 p 2 in each end of the broken hose the flow was kept at 15 cubic meters per hour and the operation pressure of the system changed from 1 090 hectopascals to 1 100 hectopascals of absolute pressure and the bubbling process maintained its quality in terms of bubble size number of them observed and uniformity of the bubbling there was no loss of gas through the broken hose after.
