- Sewage Treatment Plant- Starting, stopping
As mentioned earlier, every machinery system on the ship requires a proper procedure to be followed for starting and stopping and failure to follow this step-by-step procedure will lead to either failure in starting or stopping the machine or to some other fault.
Sewage treatment plant is one of such equipment in the ship’s engine room that requires a step-by-step procedure during starting and stopping.
STARTING
Generally, the sewage plant is running all the time while the ship is sailing. However, the plant might be required to be started manually if it is newly installed.
This is because the new plant needs to be stopped at regular intervals of time for improving its performance and maintenance procedures.
Following are the points that need to be followed for starting a sewage treatment plant:
- Make sure if any maintenance is carried out on the sewage treatment system and all the openings have been closed properly before starting
- The sewage plant is be filled with fresh water inside the chamber
- At this stage, there are no aerobic bacteria inside the chamber, but the sewage would have started coming to the plant. In order to increase the efficiency and starting rate of the plant, a bio-pacis added to the plant by flushing the amount specified in the manual
- This bio-pacis mixed with warm water, which helps in the growth of bacteria and also in efficient functioning of the plant
- If the bio-pacis not added, the plant might take up to 5 to 7 days to become completely functional. However, with the bio-pacit becomes functional within 24 hours
- Start the air compressor or open the air valve as per the design of the plant. The pressure is maintained as per the manual. Generally 0.3-0.4 bars
- Open the sewage overboard valve and close the holding tank valve when the ship is out of restricted waters
- The plant is to be continuously monitored and checked for the flow through the transparent plastic tubes
- Asample is taken for checking for suspended solids and chlorine content
- The test must be performed every week to check the performance of the system
- Some STPs are provided with 7 bar air line with solenoid valve in case the blower has to be stopped
“Do not turn off the power source of the aeration blower under any circumstances. If this happens, the micro-organism will die and thereby reduce the overall effectiveness of the device.”
STOPPING
- Stopping of the sewage treatment plant is generally done either before entering the dry dock or in case some maintenance has to be carried out inside the treatment plant
- For stopping the system, close the inlet valve to the sewage plant, then close the overboard valve and let the sewage go overboard
- Empty all the three chambers of the plant i.e. aeration, settling and chlorination chambers
- If the chambers are not emptied, it will lead to growth of anaerobic bacteria which forms the toxic H2S gas
- If entry has to be made inside the tank, the later should be checked for hydrogen sulphidegas H2S with the help of a dragortube by taking a continuous sample from the plant
- Entry needs to be made wearing mask and rubber gloves
- In case the ship is going to the dry dock, the overboard should be connected to the shore reception facilities

While the vast majority of the UK’s population relies on the main sewage system to discharge waste away from properties, it’s estimated that around 5% of houses and dwellings need to depend on off-mains solutions due to their rural location. There are a number of available options for such situations, including a septic tank, cesspool or domestic sewage treatment plant, however the latter is usually the most viable and more widely preferred choice.
Despite being the most effective solution, there are still numerous factors you should consider before you choose to install a domestic sewage treatment plant, so in this article we provide a brief overview of how they work, as well as some of the key actions and decisions that you will need to make before you proceed.
Key Takeaways:
- Domestic sewage treatment plants are a common choice for rural properties that are not connected to main sewage systems.
- Domestic sewage treatment plants work by cleaning sewage waste through sedimentation, aeration, and decontamination processes.
- Waste water treatment plants in the UK must be EN 12566-3 2005 certified, and building regulations and planning permission may be required for installation.
- Maintenance and servicing of domestic sewage treatment plants is important to ensure they function properly and meet environmental regulations.
Treatment Plant Advantages
One of the main reasons why domestic sewage treatment plants tend to be the more popular choice is because even though septic tanks are fairly low maintenance and usually less expensive, they can only be installed alongside a soakaway system. This is because current legislation dictates that septic tanks should not be discharged into a natural water source due to pollution and environmental damage, so as a result, septic tanks are unusable in areas where the ground isn’t porous enough to accommodate a soakaway system.
In addition to meeting environmental regulations, domestic sewage treatment plants also tend to be cheaper to run over a longer time frame, even though the initial outlay costs may be higher – this is because they generally only need to be emptied on an annual basis as they collect a very low level of sludge thanks to the treatment process itself, whereas other sewage systems need to be emptied more frequently which can quickly build up running costs. Treatment plants are also the most eco-friendly solution for dealing with sewage waste within a rural setting as they don’t omit ammonia – which can be harmful to wildlife and the surrounding natural habitat – and the resulting non-polluting effluent discharged by sewage treatment plants is usually around 95% clean.
How Treatment Plants Work
Generally, the sewage plant is running all the time while the ship is sailing. However, the plant might be required to be started manually if it is newly installed.
This is because the new plant needs to be stopped at regular intervals of time for improving its performance and maintenance procedures.
