Diesel
Stored diesel for generators, fleets, equipment, and standby systems.
Stored diesel, gasoline, and jet fuel picks up water, sludge, and microbes over time. Our multi-stage filtration returns it to usable condition on site, so good fuel is not written off.
Fuel that sits in a storage system for too long can give rise to problems. Fuel polishing is the process of decontaminating stored diesel, gasoline, or jet fuel through filtration, and it is the best way to restore contaminated fuel and extend its life.
Alpha Petroleum removes particulate, algae, microbial growth, and the water that seeps into stored fuel. Water reaching an engine can cause damage that cannot be undone, which is why clean fuel matters for generators, fleets, vessels, and standby systems. Our on-site and industrial cleanup crews can support the wider job when a tank needs more than polishing.
Somewhere along the way, stored fuel picks up contaminants that compromise its quality or damage the engines it feeds. Watch for these:
Alpha Petroleum recommends testing stored diesel every year, so issues are found early and addressed with the right solution before they reach an engine.

Diesel that waits in a tank for months picks up water, sludge, and microbial growth. Polishing filters it back to usable condition so the generator starts on clean fuel when it is needed. Annual testing of stored diesel is recommended.

Fleet and equipment tanks can collect dirt, water, and sediment that reach engines. Multi-stage filtration down to 0.05 micron removes them and stabilizes the fuel.

Water and sludge settling at the bottom of a tank can corrode it over time and damage engines. Polishing removes the water, sludge, and particulate; material that cannot be reconditioned can be handled for disposal.

If fuel has leaked or spilled, the release comes first. Call 24/7 emergency response so the spill can be contained and cleaned up; the stored fuel can be reviewed for polishing afterward.

The exact workflow depends on the fuel, the tank, and access. Choose the pathway that matches your situation.
You share the fuel type, tank size, storage history, location, access, and the problems you are seeing.
Alpha Petroleum matches the job to the full fuel polishing system or the compact skid-mounted unit for tight spaces.
The fuel is filtered to remove water, sludge, particulate, and microbial growth, down to as little as 0.05 micron.
The process reconditions and stabilizes the fuel so it holds its quality in storage.
Clean fuel goes back into use instead of being discarded.
For a leak or spill, call (951) 545-7374, answered 24/7, before sending a request.
Any release is contained and cleaned up through emergency response and spill cleanup.
Once the site is safe, the remaining fuel and the tank are reviewed.
Fuel that can be reconditioned is polished; water, sludge, or fuel that cannot is handled for disposal.
Our multi-stage filtration reconditions, stabilizes, and decontaminates a range of fuels, bringing them back to usable condition.
Stored diesel for generators, fleets, equipment, and standby systems.
Stored gasoline filtered of water, sediment, and particulate.
Jet fuel decontaminated through the same multi-stage filtration.
Other petroleum products reconditioned where the fuel allows.
JP8 work adheres to NFPA 110 standards.
Particulate is filtered to as little as 0.05 micron.
We offer a high-quality fuel polishing system for most jobs, and a skid-mounted fuel polishing system that is more compact and portable for tight or hard-to-reach areas such as vessel engine rooms, rooftops, and garages.
Fuel problems often connect to cleanup, waste, or transportation work. These are the services that most often sit alongside a polishing job.
You do not need every answer before you call. What you can share helps the team plan the right equipment.
Sending these details is not a quote or a guarantee that a particular tank of fuel can be reconditioned; it gives Alpha Petroleum enough to review the job and recommend the next step. All prefilled details stay editable on the quote form.
Fuel polishing is the process of decontaminating stored diesel, gasoline, or jet fuel through filtration. It removes water, sludge, particulate, and microbial growth so the fuel can be restored to usable condition instead of discarded.
Fuel that has sat in a storage system for a long time can pick up dirt, sludge, water, and other sediment, and microbes can grow in it. Water and sludge settling at the bottom of a tank can also cause corrosion over time. Alpha Petroleum recommends testing stored diesel every year so problems are found and addressed early.
Alpha Petroleum polishes diesel, gasoline, jet fuel, petroleum, and JP8 and other military-grade fuels, with JP8 work adhering to NFPA 110 standards.
The multi-stage filtration process filters fuel to as little as 0.05 micron in particulates, working to recondition, stabilize, and decontaminate the fuel.
Yes. Alongside a full fuel polishing system, Alpha Petroleum offers a skid-mounted fuel polishing system that is compact and portable for tight or hard-to-reach areas such as vessel engine rooms, rooftops, and garages.
In many cases, yes. Polishing is designed to help you avoid discarding stored fuel by filtering it back to usable condition. Whether a specific tank of fuel can be reconditioned is confirmed once its condition has been reviewed.
