How does a mobile waste water container work?
The different containerized wastewater treatment modules used depend on the specific project requirements and the effluent standards that need to be achieved.
Mechanical pretreatment of the raw wastewater is accomplished by the use of a screw screen. Theses screens remove large inorganic particles from the wastewater. Compact screens can be used to remove grease and sand [or other coarse aggregates] where necessary. These mechanical screens can be mounted on the containerized wastewater treatment plant or can be installed within the packaged plant.
Inorganic waste material removed by the screen is collected and removed offsite for disposal or further treatment. In smaller wastewater treatment plants, mechanical pretreatment can be integrated by the use of primary settlement tanks, in which case the inorganic materials are then not separated but collected along with the primary sludge for disposal.
Buffering may be required after the mechanical screening. We can distinguish between the different types of wastewater buffering as follows:
- Aerated buffering for the breakdown of simple carbon based compounds
- Unventilated buffering, for the sole purpose of managing hydraulic peak flows
- Anoxic buffering which can be required for pre-denitrification or selection processes in industrial wastewater treatment.
Most complete packaged containerized wastewater treatment systems are a combination of several stages of treatment. Where large buffering is required then the use of concrete or plastic tanks can be incorporated into the design.
Fully automatic mobile waste water treatment systems
The operation of the containerized waste water treatment plant is completely automatic and requires only a minimum of operator input. With integrated energy saving modes the mobile wastewater treatment plant can adapt to the actual volume of wastewater entering the system. This makes our packaged waste water treatment plants highly energy efficient resulting in reduced operation and maintenance.
