The fuel purifier operation on ships is the responsibility of engineer officers. Starting and stopping of the ship purifier is carried out on a daily basis to ensure service tank level is maintained. As the purifier operates, it continuously separates the impurities from the oil in the form of sludge, which can be can be discharged (by desludging operation) continuously or at a time intervals, depending upon the construction, automation, and system incorporated
In a purifier, before introducing the oil, water sealing is established so that oil fill should not flow out through the heavy liquid outlet.
Feed rate and temperature of the feed is extremely important for purification. For normal oil, one stage purification is enough, but for oil containing heavy sludge or catalyst mixture, multiple purifiers are used in either parallel (preferred) or series to get better results
The new age purifiers/ clarifiers are automatically desludged at a regular interval (by use of timer and controllers. A discharge detectors on the sludge side monitors the sludge side and provides alarm signal if any abnormality is detected.

Thanks for this vid. Very Helpful. 🙂
Hey Jayser- Thank you for your comment. Glad the video is helpful. You can watch our complete video series on Marine Fuel Oil Purifier here-

Can't express my thanks for you. Marine Insight Admin Team.
Appreciate your support 👍🏻
That's indeed a nicely detailed explanation!👏
Thank you Ashish. Glad you liked it 👍🏻
Great videos can you please make a video on horizantal and vertical shaft with thrust bearings and ball bearings that will totally complete this centrifuge series...
Hi Inam, Thank you for your comment. Please check this video - th-cam.com/video/28vO3U_k6vU/w-d-xo.html
You can check the complete playlist for marine purifiers- th-cam.com/video/2HI_dsnKRtg/w-d-xo.html
Beatifully explained...
Please do share and support 👍🏻
Sir ,can you please make a content about purifier pressure regulating valave and it's things...
Good one Sir....
👍🏻Please do share the video
My suggestion to omit the reading text. It's kind of distraction.
The origin text still clear enough to read.
Thanks Marine insight.
Keep share the videos.
Thanks for the suggestion!
thank you
You're welcome
Please inform us about level ring .. also
Very nice video sir👍
Keep watching
What is water sealing, why it is done and how does it works?
hi please can you give me an exemple when we have bad interface
3:28 why do we supply closing water at this moment? (after switching position of 3-way valve, before supplying displacement water) Is not closing water already in the bowl? How do we know that waste water overflows to the waste water outlet after suppyling displacement water?
Thank you for this video..
I have a question...the discharge valve to the service tank is the valve known as backpressure valve?? I heard also that backpressure should be aprox. 2bar can you explain why? With what criteria should someone adjust the pressure flow from puryfier to service tank?
I will appreciate any answers ! Thank you!
The back pressure varies as the temperature, density, viscosity of feed oil inlet varies. The back pressure ensures that the oil paring disc is immersed in the clean oil on the way of pumping to the service tank.
Super sir , could you upload the vedio regarding the pipes on it and what it carry on purifier
We do have a series of video on Purifier - Please do check: th-cam.com/video/2HI_dsnKRtg/w-d-xo.html
3:12 why we have to send bowl closing water again? The bowl is already in closed position, right?
I have question sir
1. How to adjust the feed rate and backpressure?
2. How much is the pressure of dirty oil inlet and clean oil outlet on the purifier?
Hi there. Can you explain briefly, how does paring tube work in Alfa Laval separators model s?
Paring disc helps the clean oil go to the outlet side with pressure.
Thanks.... 😊😅But there is doubt.... That how operating eater and desludge water works...?
Hi Vaibhav
Please watch this video - th-cam.com/video/n-LTUJjvXxA/w-d-xo.html
Let us know if this is helpful!
Sir what is a back pressure in a purifier!
Pls make purifier, centrifugal pump overhauling video
Thank you for the suggestion 👍🏻
What is replacement water? And what is displacement water?
Before de-sluging, the feed is stopped. Now the displacement water is released which displaces the remaining oil and send it to the oil outlet making sure the least amount of purified oil goes to the sludge side during de-sludging process.
One question sir
1) The sealing water which we provide does it remain in the purifier during normal purification of oil (or does it just flushes out, then we feed oil)
2) we use purifier to separate out water nd sludge particles present in oil but y additional sealing water??
Kindly explain sir.
1.it will there in the purifier till the de sludging process
2.sealing water is to seal the path of sludge...it doesnt involve in any other operation....it is just to maintain the bowl upwards
Why the fuel comes down from the bottom of the fuel purefing?
Because of the piping and construction
Where is back pressure valve on purifier on inlet pipe or outlet pipe ?
It is on the outlet pipe of the purifier.
marineinsight plz explain y we r using back pressure v/v
Surveyor asked me what was the name of the desludging mechanism in the purifier?????
Different models and make have their own desludging mechanism. Alfa Laval purifier will have different mechanism when compared to the Westfalia make.
Whic is better westfalia or alpha naval....?
Both have their own advantage.
I just want to ask sir. What could cause the electric motor on an oil purifier to trip out in overload?
It can be due to -
Stuck belt in belt drive purifier
Wrong assembly of bowls and parts after overhauling
Broken or stuck gear tooth in gear drive purifier.
Worn Out frictional clutch assembly
Brake assembly malfunctioning.
What could cause the electric motor on an oil purifier to trip out in overload?
A. The bowl contains too much sludge
B. Worn and gear wheel badly damage
C. Insufficiently tighted bowl hood
D. Oil temperature is too low
That is the choices sir, i don't know what is the right answer hehe
B Worn and badly damaged gear wheel
During desludge .displacement water introduced not the sealing water
I have question sir
1. How to adjust the feed rate and backpressure?
2. How much is the pressure of dirty oil inlet and clean oil outlet on the purifier?
