Sewage treatment Plant on board ships! What happens after you flush! 

Success my friend im glad it was helpful

You're welcome, everything is so interesting in the engine room haha

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!

Thank you for watching the video! The world underneath ships is a wonderful and curious adventure of engineering and mechanics

God hear you my friend, I hope so. Thank you

You're welcome and than you for your support Eduard, success my friend.

Just trying to be curious like always Dino, I hope that never changes even as an officer!

Glad you think so! My friend I try my best

@@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

My pleasure, success Elif!

Muchas gracias Jagor! Éxito y más nada amigo

This coming month is the month for new videos for sure! Hopefully I lll be able to keep a schedule!, 😁😁

Yeah amigo, this was one of my first videos, I keep trying to learn new things each time.

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!

gary unsing I'm honored I could be of help amigo.. Welcome and success to you my friend.

@@ShrimptoShark off course waiting for your further videos...😊👍

Thank you my friend, I'll keep doing my best, success to you too!

@@ShrimptoShark thankz bro... !!!

D R P why thank you, that's very nice of you to say! Success and nothing else😉🛠️

Of course my friend I will continue working hard to share jobs and life in the engine room

You are awesome dude!

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

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).

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).

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

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.

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

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

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.

@@ShrimptoShark thanks

That's correct the pump creates the vacuum of the toilet system and discharges to the plant.

Hahah working and having fun

That is correcto amigo

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

There is boiler water análisis, if you. Mean potable water there is also a small video showcasing the basics

Hello my friend I try to be active on social media however lately life has been pretty stressful! Instagram Facebook, etc

Well dude its a Suezmax crude oil tanker, however the names of the vessels I work on Ill keep to myself, its better that way in my opinion.

Heya dude! Well in reality I didn't think much about that..now I understand it a bit more and as long as education is free I'm happy!

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.

Ufff I have to make a video on how to make the concentration! Sorry for the late reply.. It will come soon 😂

@@ShrimptoShark plz make it soon... Waiting... 😇 By the way u can answer me here in short... Bcoz still couldn't find... 😉

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

@@ShrimptoShark ok thank you... I have 12.5 % solution on board. So i don't have to add any water to it???

@@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

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.

If you are curious about the type of Sewage plant then its IL SEUNG Biological Sewage Plant model - ISS35N

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

guess its 3. ; )

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.

@@ShrimptoShark hola. Yes thanx brother. The video is helpful and enjoyed it. Keep grinding 💙💪

Athlantha Fernando 3 NM

Shrimp to Shark so thats mean, even have through prosses Treatment inside Sewage is not allowed discharge to Over Board ???

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.

Hahaha the bacteria actually eliminate oder! It's not so bad
