Thank you so much man, i'm a engine cadet like you...and this video is very clear! best regard and the wind is always from yours! Greetings from italy.
I hope you can also share some of your experience and knowledge to the future cadets as well Salvo, Thank you for your support, Greetings from Venezuela!
Your video is very helpful. Im a motorman on a general cargo vessel and our seawage plant is smaller but more likely the same working principle. And also your wiper looks like filipino same as me.
I'm glad to have shared something familiar to you amigo! And the wiper is from Myanmar a country near Malaysia! Very friendly and polite people, I'm happy to work with them, still haven't worked with people from the Philippines yet unfortunately 😞. Success my friend Ricardo
Really a great video and nice explanation but please reduce the background music sometimes the music is annoying .......if it is in lower volume it'll be nice.....nice work brother.
As a 'global ecologist' I am keen to understand what is actually going overboard. I am one of those who are starting to look into what leaves the dock comes back to the dock. This includes the fact that what is on board never changes in volume in terms of food/drink etc. Matter is matter. So the storage may be a problem, due to space and weight but I can not see it being impossible. With the advent of hydrogen powered electric propulsion systems I believe shipping has the chance to be extremely ecologically minded. This could be a huge game changer for our future.
@@ShrimptoShark i will recommend your channel to all my friends in navel architecture and marine engineering department,i am planning to be in your place after graduation , thank you for videos again it really help
It will run, however not for long, first the bacteria will die thus the decomposition of sewage in the first chamber will be poor, then large sludge will be transfered to the setting tank and without air from the blower there will be no recirculation to the bacteria chamber. The sludge will then clog the screens and eventually the whole system will be clogged, you will notice because the discharge pump will not automatically start because no new sewage will go to the chlorination tank (4th chamber).
Upon cleaning the stp compartments, when will an aerobic bateria start to live and grown again? will it take only hours? or days for them to live again?
Heya Kim, well there is another video I plan on uploading eventually which shows the chemical Gamazyme from UNITOR and how to apply these bacteria in our black and Grey water system.
To directly reply to your question, after washing or backflushing a tank we add bacteria and while the system is working (Sewage air and water mixed) bacteria will start to reproduce and about a few days to a week for full performance (according to the manual) check the manual of your Sewage plant for unique details respective to your local system.
Hello Usama! Well the blower in our case can be stopped due to the forward or back end bearing being stuck (it should be changed every 6 months) also if high load (if someone forgets to open air valves) which will cause an overload trip, and another case is simply someone turns it off because of a leak in gakset and the blower expels bad smelling gas out (which I've heard has happened).
Now the consequences for the blower not running are numerous! It's connected to 3/4 chambers! 1)areobic bacteria WILL DIE, and be replaced with anareobic bacteria like explained in the video. 2)the return line of the sedimentation tank will not work therefore heavy sludge will stay at the bottom and clog the return line and eventually the whole system! 3)the activated carbon tank has a screen at the bottom as shown in the video to keep floating soilds out.. If there is no air these solids will be slowly pressured into the screen and without any air to free them, will become stuck! Blocking this chamber as well.. And maybe you can imagine some other problem? To tell you the truth this system is interesting if you go in details haha
@@ShrimptoShark so in that will sewage in the aeration break in small component i suppose no ..because the bacteria in the aeration chamber needs oxygen which eat and reduce into small particles . But i am confuse how the settle sediment again transfer to primary tank by which means
usama jadoon I mention this @ 3:16 where heavy sludge sinks to the bottom of the tank. Air from the blower creates a sort of ejector that sends this sludge in a return line to the 1st bacteria tank in order to continue decomposition of heavy sewage.
Solid trash is accumulated, sorted, and burned (I hope to show this in the future) in the incinerator as well as heavy sludge (as shown in my sludge management video).
Can you do videos on Fat, oil, and Grease from the galley. Curious to know where all that water goes and how the system is supposed to work to prevent solids filling up the grey water tank. I had that situation happen.
I'll try to make videos about Grey and black water as well as gamazyme a special chemical from unitor to prevent clogs and to activate the sewage plant and pipelines
Hello bro, what do you mean? Input of sewage? That of course depends on number of people on the ship if you mean discharge flow rate that also depends on the speed of the vessel and capacity of the tank
I'm glad to read you have lots of curiosity! Ask questions, read instruction manuals, view more youtube videos and don't worry with work comes experience onboard. Success my friend
Hello my friend there are many videos explaining that process and depends on how much detail you want...I'll make a video on that in the near future as purifiers were my favorite machine onboard along with the sewage plant.
OK quick answer the tank or manual usually says how much concentration you will dose for example on that plant it was 12.5% NaCl.. We had in our chemical store 90%NaCl liquid.. So you need to make a V/V solution.. The tank is 20L.. So 12.5% of 20L is 2.5L of 100% NaCl.. Since the chemical we had is 90% you need to factor that in so you make a correcting factor 1.1.. 2.5 * 1.1 = 2.75L of NaCl (90%) to make a solution of 12.5% in the 20L tank. I hope that's clear.. If the you have tablets instead it would be 1g = 1ml
@@vinayakk6328 if the chemical is already 12.5% you don't need to add any water! Just fill the chemical tank normally! But make sure that the plant requires that concentration
In my engine cadet introduction video I explain how we start this career path as maritime engineers, however this also depends on your country my friend
Hello and thank you vaisakh! Back flushing on this plant is usually done to the 3rd and first chamber following the manuals instructions but sure I can make a video on how that's done.. Sea water is only used on the holding tank however in the treatment plant we use hot water from the calorifier (electric and steam heater)
@@ShrimptoShark Even if u can't make a video of how backflushing is done kindly explain it.. becoz u r good in explaining things simple and perfectly also
Sir just want to ask why your videos has no adds. Did you undergo monitization of ur channel? Your subscriber already pass the requirements of YT. Then, you have plenty viewers also. Why there is no AdSense
This sewage plant is made to receive both black and grey waters. The difference between these types of sewage I want to show in a future video about the chemical bacteria GAMAZYME and the maintenance of these pipelines. However if you are curious a good rule is: Black Water - From toilets and the Hospital (Where water is possibly infected) - Very dirty sewage Grey water - From Sinks, Showers, Galley, drains in the accommodation, Laundry, etc. can be contaminated with cleaning chemicals, food, soap, and domestic stuff like that.
Athlantha Fernando hello Amigo, yes it's 3 Nm from nearest land, Between 3 and 12 it should be commuted (made small by grinding or maceration) and disinfected. 30L/Nm at 50Nm is familiar to me only as the discharge rate of cargo washings if I'm not mistaken from the ODME on oil tankers such as I am on.
Hmm I would imagine it's very different a cities sewage plant than a ships. Onboard we must operate much more than the sewage plant but it is more simple than on shore.
Tbh one of best video I have ever seen about STP. Chapeau bas!
Success my friend im glad it was helpful
Wow! My curiosity led me here. So interesting! Thanks
Thank you for watching the video! The world underneath ships is a wonderful and curious adventure of engineering and mechanics
Wish I had an Engineer like you, on my Ship...Hard working, knowledgable n charming. Wishing u very best of luck..
Haha I don't know about charming but I have fun doing what I do, hope that's the same for more engineers around the world. Success Satya!

It is necessary to put a holding tanks with vessel manning capacity of 22? It is required by marpol?
Well our ship had 30 crew and we used a holding tank.. I mean you can not discharge black/Grey water in Port you must be outbound
can you please send your vaccum sewage system manual ?
Vacuum pump it takes suction direct from toilet system to sewage treatment plant?
That's correct the pump creates the vacuum of the toilet system and discharges to the plant.
Nice Video.....Thank somuch..
It's my pleasure my friend, success
I've never been on a ship, but what do you do with the heavy sludge/solids? I suppose they will accumulate over time.
Solid trash is accumulated, sorted, and burned (I hope to show this in the future) in the incinerator as well as heavy sludge (as shown in my sludge management video).
