Alberta Diesel Dialysis uses Certified Independent Lab results for all fuel sample testing. CSA requires the fuel to filter to 20 microns.
Alberta Diesel Dialysis's systems filter down to 3 microns and lower.

Section 11.5.5 Visual Inspection of Fuel (clear and bright test)
7.5.3 Fuel Quality
The fuel shall meet the engine manufacturer’s specification
Note: See Clause B.11 for Commentary on this clause.
11.5.5.1 General
All fuel supplied to the emergency generator set shall be clean and clear and bright as specified in clause 11.5.5.4. Immediately upon completion of the annual fuel oil inventory maintenance specified in Table 5, the fuel oil shall be tested to verify that it is clear and bright. If the fuel fails the test, the tank shall be flushed to remove the built-up sludge and impurities.
Note: The purpose of the test is to detect possible water or solid contaminants in diesel fuel by visual inspection, The test method is based on ASTM D 4176
11.5.5.2 Description
The fuel shall be placed in a transparent bottle or container (see Clause 11.5.5.3) and examined to determine whether it is clear and bright. Samples for the clear and bright test shall be obtained from the bottoms of the storage and day tanks.
11.5.5.3 Equipment
A dry, capped, clear glass bottle or container capable of holding 250 to 1000 ml of liquid shall be used. The bottle or container shall have a clear, undistorted bottom and be thoroughly washed before the test.
11.5.5.4 Procedure
The following procedure shall be followed:
Wash the fuel sample bottle or container before gathering each sample.
Let the sample settle for 1 minute to remove air bubbles.
Observe the sample against a light background for a clear and bright condition. Swirl the bottle or container to create a vortex (free water and solids tend to collect beneath the vortex)
11.5.5.5 Interpretation of Test Results
The samples shall be clear and bright or not clear and bright. Record whether particulate matter or water was seen at the bottom of the vortex. Note: The term “clear and bright” has no relation to the natural fuel oil colour. Fuel oil colour varies from water white, to straw colour, to amber, depending on the processing and/or crude source. Clear and bright fuel has no floating or suspended matter. Brightness is a quality independent of the sample colour and refers to the lack of suspended or free water in the sample. Bright fuel tends to sparkle.
Table 5
Item 4. Diesel Fuel Storage Tank(s)
The fuel oil in any storage tank (and day tank, if used) shall be tested in accordance with clause 11.5.5 and if the fuel oil fails the test, it shall be Drained and refilled with fresh fuel in accordance with article 6.7.1.5 of the National Fire Code of Canada, or
Full filtered to remove water, scale, bacteria, and oxidized gums/resins in order to minimize filter clogging and ensure diesel start-up (see clause B.20 for commentary).
When fuel is filtered, it shall be treated with a suitable conditioner and stabilizer to minimize degradation while in storage.
Note: The bottom(s) of the tank(s) shall be also tested chemically for water.
Clause B.20 (Table 5, Item 4(b))
When fuel is being filtered, the following procedures should be followed:
The fuel should be filtered to a maximum particulate size of 20 µ and the filtered media should be capable of removing water.
The fuel (if it is being recirculated in the same tank when being filtered) should be filtered for a period of time at least three times longer than the period necessary to process the volume of fuel in the tank once. For example, if the volume of fuel is X and the filter unit will process X volume in 30 min, the filter unit should be run for at least 1.5h. This will achieve a reasonably good level of filtration. At the same time, an effort needs to be made to agitate the fuel and any contamination at the bottom of the tank to ensure treatment.
Provision should be made by the designers and installers of the fuel tank(s) for easy access to the fuel by the filter unit suction and return probes, with sufficient overhead clearance above the tank(s) and also suitable blank plugs or similar devices in the top(s) of the tank(s) for the probes to be easily inserted without excessive work.
Canadian Electrical Code, Part 1 2006
Item 46-202 (3) Where a generator is used, it shall be In conformation with Canadian CSA-C282; except for a generator installed in a health care facilities as described in Rule 24-306

Article 6.5.1.3 Instructions
1) Where an emergency power system is installed, instruction shall be provided for switching on essential loads and for starting the generator when this is not done automatically.
Article 6.5.1.4 Records
1) Written records shall be maintained as required in CAN /CSA-C282 “Emergency Electrical Power Supply for Buildings.”
Article 6.5.1.5 Supply of Fresh Fuel
Liquid fuel storage tanks shall be drained and refilled with fresh fuel at intervals not greater than 12 months. (See Appendix A)
Appendix A
A.6.5.1.5 (1) This can be achieved by replenishment as the result of the routine test program required by Article 6.5.1.1
Objectives of Fire Code:
F40 To limit the level of contaminants.
F43 To limit the risk of release of hazardous substances.
F44 To limit the spread of hazardous substances beyond the point of release.
F81 To minimize the risk of malfunction, interference, damage tampering, lack of use or misuse.
F82 To minimize the risk of inadequate performance due to improper maintenance or lack of maintenance.
