SEWAGE TREATMENT PLANT ON SHIP ....

Working
A typical ship STP is having 4 chambers
Primary Chamber
Aeration Chamber
Settling Chamber
Chlorination Chamber
Primary Chamber
The row sewage enters the primary chamber via a coarse mesh filter where large solids are broken down. The advantage of breaking sewage in small particles is that it increases the area and a high number of bacteria can attack simultaneously to decompose the sewage.
Aeration Chamber
The sewage enters the aeration compartment where it is digested by aerobic bacteria and microorganisms. The aeration chamber is where the main biological action takes place. Here air blowers mounted on the outside of the unit oxygenate and stir the effluent and bacteria mix via a series of pipes and nozzles. The sewage remains in this aeration tank for some time.
The sewage is decomposed into carbon dioxide, water, and inorganic sewage
Settling Chamber
The sewage then flows into the settling compartment where the activated sludge is settled out. Any solids that settle out are returned via an air lift to the aeration chamber which ensures that they are fully broken down. This returned sludge contains the bacteria to digest the incoming sewage.
Chlorination Chamber
The clear liquid then overflows from the settling tank to the chlorination chamber, and the chlorinator disinfects the liquid. The chamber has float switches, which control the discharge pump, and a high level alarm.
How does sewage treatment plant works on ship?
Principle and Working
The basic principle of a biological sewage treatment plant is the decomposition of raw sewage with the help of aerobic bacteria. This is done by aerating the chamber with fresh air.
What is the STP system in a ship?
STP Blower:
In a ship's sewage treatment plant, an air blower is a vital component used in the aeration process. The primary purpose of the air blower is to supply oxygen to the biological treatment unit, which helps in the breakdown of organic matter present in the sewage.
What is the sewage treatment plant test on a ship?
The sewage chlorine test on a ship is a procedure used to measure the concentration of chlorine in the ship's sewage system.
What is the principle of STP?
The principle of a Sewage Treatment Plant (STP) involves the treatment of wastewater through a series of physical, biological, and chemical processes to remove pollutants and contaminants. The primary principle is to mimic and enhance natural processes that occur in the environment to purify water.
