What Is a Containerized Wastewater Treatment Plant?
A containerized wastewater treatment plant integrates major treatment equipment into a standardized container structure. This approach can simplify transportation and installation while providing a compact footprint — treatment capacity arrives at the site as a factory-built, factory-tested unit.
Depending on the wastewater type, a JM series plant can incorporate biological treatment technologies such as MBR or MBBR for domestic sewage, MABR for energy-efficient biological treatment, or a project-specific process configuration for industrial effluent. For sites where freshwater is limited, containerized reverse osmosis desalination is also available.
Containerized wastewater treatment systems are particularly suitable for projects requiring:
✓ Rapid installation
✓ Modular expansion
✓ Remote deployment
✓ Limited construction work
✓ Flexible relocation
✓ Factory-integrated equipment
Why Choose Mejec JM Series?
-
Factory-Built Container Design
Major treatment equipment is integrated and tested inside a standardized container structure, so the plant arrives at the site complete and ready for water and power connections. -
Modular, Expandable Capacity
JM-MBR/MBBR plants provide 50–600 m³/d per unit and can be combined to roughly 10,000 m³/d, while JM-MABR systems cover capacities up to about 1,000 m³/d — capacity grows by adding units. -

Frequently Asked Questions
What is a containerized wastewater treatment plant?
A containerized wastewater treatment plant is a complete treatment system in which major equipment is integrated into a standardized container structure. It is prefabricated and tested in the factory, then delivered ready to connect — simplifying transportation, installation and on-site construction compared with site-built plants.
Which JM system is suitable for domestic sewage?
For domestic sewage, the JM-MBR/MBBR containerized plant is designed for flows of 50–600 m³/d per unit and can be combined to about 10,000 m³/d, covering towns and villages, scenic areas, temporary facilities, remote communities and residential or commercial developments.
What is MABR and when should it be selected?
MABR (membrane aerated biofilm reactor) technology uses gas-permeable membranes to support biological treatment. It is particularly relevant to compact, modular systems where energy efficiency and efficient use of space are important, and can reduce aeration energy by about 70–75% compared with conventional aeration.
Can a containerized wastewater treatment plant be expanded?
Yes. Modular and containerized wastewater treatment systems can provide greater flexibility for phased projects — additional treatment units can potentially be integrated as wastewater flow increases, subject to the original system design and available site conditions.
Can JM systems treat industrial wastewater?
Yes. JM-IWTP containerized plants are configured according to the specific characteristics of the industrial effluent. Solutions can be arranged for applications including electroplating, mining, metal processing, manufacturing facilities, industrial parks and remote industrial sites.
