In order to find out how much "dirt" one CJC filter cartridge can contain, the following test was carried out with an HDU 427/108 filter system containing 16 cartridges of type HDU 27/27. The application was filtration of engine lube oil (on board a container ship).
According to Weight:
| Weight of one set of used cartridges | 225.00 kg |
| Weight of one set of new cartridges | 58.08 kg |
| Contents of the set of used cartridges | 166.92 |
According to Volume:
| Volume of one set of used cartridges | 200.00 ltr. |
| Volume of cellulose in one set of new cartridges | 52.80 ltr. |
| Volume of oil and sludge in set of used cartridges | 147.20 ltr. |
To calculate the specific gravity of oil and sludge: 166.92 kg / 147.20 ltr. = 1.13
According to engine oil / sludge data tables, we can determine that the sludge content is 0.94 (94%) for a specific gravity of 1.13
Therefore, we can deduce that the used filter cartridge set contains the following weight of sludge material: 0.94 x 166.92 kg - 156.90 kg
This further translates to an individual cartridge containing the following weight of sludge material: 156.90 kg / 16 cartridges per set = 9.8 kg per cartridge (21.5 lbs per cartridge)
It should be noted that the weight of contaminant contained in a single cartridge will vary depending on the application and type of contaminant. We have found through many years of experience that the weight of contaminant contained in a single cartridge type HDU 27/27 and B 27/27 averages between 5 kg and 7 kg (11 lbs and 15 lbs).
