Oil Water Separator Installation Process

Preparing the Tank and Lines

Cleaning and Debris Removal

You need to get your tank and lines ready before you put in oil water separators. This helps your system last longer and work better. First, take out big pieces and floating trash from the bilge water. Use strainers to catch these things before they get to the oil water separator filter. This stops the filter from getting blocked and keeps everything running well.

Here are some good steps for cleaning and removing debris:

1. Use strainers to catch big trash.

2. Try not to let too much oil get into the bilge wells. Move large amounts of oil to a special oil tank.

3. Warm up the bilge water. Warm water makes oil come out faster.

4. Do not mix sludge or other dirty stuff with bilge water.

5. Fill the oil water separator with clean water. Make sure there is no air inside.

6. Backflush the oil water separator filter often to keep it working well.

7. Clean the interface sensors a lot so you get good readings.

8. Take out any leftover oil in the separator chambers by hand.

Tip: Always do what the manufacturer says for cleaning and care. Taking care of your system stops big repairs and keeps your ship following the law.

Installing Risers and Adapters

After you clean, you need to put in risers and adapters. These parts help connect your tank and lines to the oil water separator filter. Pick the right size and type for your system. Make each riser and adapter tight so nothing leaks. Check all the connections to make sure they fit well. This step helps water move into the oil water separator filter and keeps oil from leaking out.

Positioning the Separator

Leveling and Securing

Put the oil water separator on a flat and steady spot. Use a level to see if the unit sits straight. If it leans, oil and water will not split well. Hold the unit down with mounting brackets or bolts. Tighten all the bolts so the separator does not move when the ship is working.

Note: A flat and steady oil water separator filter works better and leaks less.

Accessibility

Pick a spot that is easy to reach. You and your crew need space to check, clean, and fix the oil water separator filter. Good access helps you find problems early and fix them fast. Make sure there is enough room to take out and put in the oil water separator filter parts when you need to.

Oil Water Separator Filter Setup

Filter Element Placement

The oil water separator filter is the most important part of your system. Put each filter element in the right place. Follow the steps in your manual. Each filter element must fit tight in its spot. If a filter is loose, oil can get through and the system will not work as well.

Here is how you usually set up the system:

1. Put the oil water separator in a clean and easy-to-reach place.

2. Connect the separator to a condensate manifold that collects water from all main parts.

3. Make sure each part has a drain line going to the manifold.

4. Let water go through drain valves into the manifold.

5. Let the water go into a chamber for cyclonic depressurization.

6. Send the liquid into a polypropylene oil water separator filter cartridge to catch oil.

7. Move the water through an activated carbon cartridge to grab the last oil bits.

8. Let the clean water go out through a safe drain.

The kind of oil water separator filter you use changes how well your system works. The table below shows how different filters work at different flow rates and temperatures:

You can see that filters work better with higher flow rates, especially if you use oleophobic filter media. These filters catch oil drops better because they make a thick film and stop liquid channels.

Water Filling Procedure

Before you start, fill the oil water separator with clean water. This step gets rid of air and gets the oil water separator filter ready to work. Open the water inlet valve slowly. Look for leaks around the filter housing. When the chamber is full, check that all filter elements stay in place. If you see bubbles, fill again until only water comes out.

Alert: Never run the oil water separator filter without water. Running dry can break the filter and make the system work worse.

Now your oil water separator filter is ready to use safely and well. Checking often and setting up right keeps your system working and helps you follow all the rules.

Plumbing and Electrical Connections

Connecting your oily water separator to your ship’s systems is a key step. You need to set up both the pipes and the power. Good connections help your separator work safely and meet all rules.

Inlet/Outlet Piping

You must connect the pipes that bring oily water in and send clean water out. Start by checking the pipe sizes. The inlet pipe brings oily bilge water to the separator. The outlet pipe carries treated water away.

Steps for Piping:

1. Measure the distance from the bilge to the separator.

2. Cut pipes to the right length.

3. Attach the inlet pipe to the bilge pump outlet.

4. Connect the outlet pipe to the clean water discharge point.

5. Use strong clamps and seals to stop leaks.

6. Check that all joints fit tight.

Tip: Use corrosion-resistant pipes. Stainless steel or high-grade plastic works best on ships.

You should keep the pipes as straight as possible. Bends and turns slow the flow and make cleaning harder. If you must use bends, keep them gentle. Place shut-off valves near the separator. These valves help you stop the flow for cleaning or repairs.

Table: Common Pipe Materials and Their Benefits

Check for leaks after you finish. Run water through the pipes and watch each joint. Tighten any loose fittings. A leak-free system keeps your ship safe and clean.
