How Does a Containerized STP Work?
The treatment process varies depending on the selected technology. A typical biological containerized STP may follow the process below.
Sewage Collection
Domestic sewage from toilets, bathrooms, kitchens, washing areas, and other sources is collected and directed toward the STP.
Screening
The incoming wastewater passes through a screening system that removes coarse materials such as:
- Plastic
- Paper
- Cloth
- Hair
- Fibres
- Other large solids
Screening protects pumps and downstream treatment equipment.
Equalization
An equalization section can balance variations in sewage flow and pollutant concentration.
This helps provide a more consistent flow to the biological treatment stage.
Biological Treatment
Biological treatment uses microorganisms to break down biodegradable organic matter present in sewage.
Depending on the selected technology, the containerized STP may use:
- MBBR
- SBR
- MBR
- Extended aeration
- Activated sludge processes
Aeration
Where an aerobic biological process is used, air blowers and diffusers supply oxygen to the biological reactor.
Adequate aeration supports the microorganisms responsible for biological treatment.
Clarification
After biological treatment, suspended biological solids are separated from the treated wastewater.
A clarifier or suitable solid-separation process can be integrated into the system.
Filtration
Additional filtration may be provided to improve treated-water clarity.
Depending on the application, filtration can include:
- Pressure sand filter
- Activated carbon filter
- Micron filtration
- Membrane filtration
Disinfection
Disinfection can be provided to reduce microorganisms in treated water.
Possible systems include:
- Chlorination
- Sodium hypochlorite dosing
- UV disinfection
The appropriate system depends on the intended application and water-quality requirements.
Treated Water Storage
The treated wastewater can be transferred to a treated-water storage tank.
Where permitted and where the required quality is achieved, treated wastewater may be reused for suitable non-potable applications.
