- sewage treatment plant onboard ship
Sewage treatment plant is used to treat the sewage and make it less harmful for the sea. Marine engineers must know the operation of the sewage plant before using the same in order to comply with the rules and regulations of discarding sewage.
Informative.
May ALLAH bless you.
Love from Pakistan.....
Really awesome bro.. you explained very well.. thanks for latest regulation on discharge condition
And bro what us your rank on-board right.. are you 2nd
SKP se acha padhate Hain sir....Love u sir ,make more videos

Means alot thankyou
Thank you so much sir.
Welcome
Amazing sir .Really helped a lot
🙌
Incredible ❤
vry informative video please can u make a video on the mainatanance carried on sewage treatment plant and the safety measures to be followed while working on this plant.
Noted
❤️❤️❤️
So thank you sir
Thank you sir
Your welcome
Blessing you God.......
Thankyou brother!
Nice explanation. Sir why foam coming out from vent.
thank you so much sir
Always welcome
Is the blowers are runs continuously or cut out cut in is there and why?
thanks sir
Thank you, Sir
Welcome brother!
Many new ships uses sea water or fresh water for back flushing instead of grey water .
Dear Dixit. Thank you for giving us such a good information. Please always take part in discussions. Thank you.
Can you please explain the process of back flushing using sea water?
Back flush bhi describe kar do sir
❤
Hello sir, thanks for this video. Sir my ship was 2000 built gas tanker. Here these 3 chamber has common line which is connected to overboard pump. Now on our ship we had also sea water line connection to this common line to backflush. However, at some time, we used to open STP, and manually clean, later fill again with sea water, open all the valves,, start blower. when it reaches certain level, air bubbles with water can be seen in inspection pipe during operation.
what should be the pressure of this grey water and how the grey water will pass from sterilization tank to the other tanks for flushing
Nicely Explained. Can you please share the block diagram as well. TIA
Sure! soon will provide link for the same.Thankyou.
Sir if activated sludge is removed from settling tank with venturi effect isn't there a greater possibility that the nozzle could be blocked by sludge..?
And anthour question what steps to be adopted when we are running out of chemical during sailing
Sir 2 questions-
1)If blower fails,action ??
2)If discharge color is grey,reason and action?.
Sir short mai hi bata dijiyega.
There is standby blower if one blower fails second blower comes..
The requirement of blower here to supply air to the chamber to allow the aerobic reaction if air is not supplied then anaerobic reaction takes place inside the chamber and hydrogen sulphide' gases are released that cause marine pollution.
Grey water is generally cooking and cleaning waste
Thank u so much sir.
Dangers while opening biological stp for repairs? How to minimise the risk
Sir if grey water is used to wash out the sewage stuck at the walls of the primary tank, then why is the grey water feeded directly to the chlorination chamber,as shown in your diagram?
Grey water is used to wash or flush out the stuck sewage and particles from the system.
Now come to your Question ...Please follow the path Carefully. Feed the grey water into the chlorination tank then it overflows and flows into the carbon filter wash or flush the stuck sewage particles from this chamber and then again grey water overflows into the sedimentation and primary chamber and does the same function. and in this way grey water flash out the stuck sewage and particles from the whole system and at the bottom part there is arrangement of valve. Open the valve hence all flush out water drain out.
Analyse the flow path of grey water properly.
Thank you!
@@searainly Hello sir....Hope you are ok..
I have a doubt on the same thing that on my ship 1st is bulky and 2nd one is tanker we used to flush STP with sea water in our daily routine and the grey water is thrown ovbd through different pipeline and the ovbd vv is Both port and stbd side??
Have you sailed on the ship on which grey water is used for flushing or you have read it from somewhere???please make me understand because we have seen sea water flushing not with grey water??
Sir one important question please reply asp que - what is procedure adpoted when STP is out of order on borad ship?
Sir explain about ejector in this system
Sure 👍👍
How can I reach to you plz ?
Sir if possible please make on IC also
After completing Marine Aux M/c will make videos on main engine topics also.Dont worry.! Thankyou.
Sir which device is used for measuring BOD 25mg/L.? Kaisa pata chalega
Please also explain Aerobic and An aerobic chemical reactions also
Explain about airlift of activated sludge. You said its sucks air out of ventury, i doubt it is opposite. Can you clearly explain?
I already said activated sludge get sucked (with the help of venturing effect) and it return through returning sludge line and again mixes with incoming sludge.
Sir ji engine room piping layout pe ek video, please sir 🙏
Sure brother! MAM k part m hi cover krunga Just give me sometime. Thank you!
What should be checked on sewage treatment plan during watch?
About stp maintenance?
Pr. Of blower in aeration chamber is 0.3 to 0.5 bar.
Atmospheric pr. Is approx 1 bar.
How does the blower making the pr. Of .3 to .5!!!!
Sir, how to control/reduce BOD and COD of sewage treatment plant. What actions can we take onboard ship?
Awlllaaa
Sir, 25mg/ltr of what?
As per MEPC the concentration of sewage which is going to be overboard must be less than 25mg/litre .
not more than 25mg /ltr of Suspended Solids should be present In the treated Affluent that is being discharged overboard as per MEPC.
What about omnipure stp
OMNIPURE(Name) is the manufacturer of high quality, cost effective waste water system..Most of the Marine STP is Omnipure marine sewage system that oxidizes sewage in an electrochemical cell as well as generates sodium hypochlorite for the disinfection of the sewage streams.
@@searainly pkz make one video on that
Thank you for your response and suggestion.. Will try to upload video on this topic soon.
Sir in this video how biological oxygen demand is confirmed as 25mg/l.ye kaise calculate karenge?
The effectiveness of Sewage analysed by taking 1 litre of sewage sample and incubating it for 5 consecutive days at the temperature of 20 degree Celsius with well oxygenated water.
Now The amount of oxygen used up by the sewage in mg/l or PPM KS termed here BOD and In this case that BOD comes is 25mg/L(u have to continue with this process BOD reaches up-to 25mg/l & This new resolution value is set by MEPC.
Bahut bahut dhanyabad sir.
please explain it in English
