Current Treatment Needs
The initial phase is designed to provide the treatment capacity required for the project’s current stage.
MEMPAC-M2 THROUGH M12
Phased treatment designed to grow with your project.
For domestic wastewater projects where treatment capacity will be installed in planned phases, the MEMPAC-M Series offers six phased, expandable models with design flows from 167,000 to 1,000,000 GPD. Future phases are incorporated into the initial system design, equipment configuration, and site layout so treatment capacity can be added as planned.
PHASED EXPANSION PLANNING
Build today with future phases in mind.
Phased expansion begins during the project’s initial design. Cloacina works with the project team to evaluate current treatment needs, anticipated growth, site conditions, and the expected timing of future capacity.
The system layout and equipment configuration are then developed around the planned phases. Projects that may require future treatment capacity should establish the phased approach before the initial system is designed.
PLANNING CONSIDERATIONS
Anticipated Project Growth
Expected development, future wastewater flows, and the timing of additional capacity help define the planned phases.
Integrated Site and System Planning
The equipment configuration and site layout are developed with both the initial system and future phases in mind.
Important Planning Note
Phased expansion must be incorporated into the initial project design. It cannot be added to a system that was originally designed for a single build-out.
AVAILABLE MODELS
Six models available for phased expansion.
The Phased Expansion Path includes six MEMPAC-M models with design flows ranging from 167,000 to 1,000,000 GPD. Cloacina determines the appropriate model, initial capacity, and planned phases based on the project’s current needs and anticipated growth.

TYPICAL APPLICATIONS
Domestic wastewater treatment for a wide range of projects.
Phased, expandable MEMPAC-M systems can support domestic wastewater projects where treatment demand is expected to increase as development occurs. Every project is evaluated individually based on its flow, anticipated growth, site conditions, and treatment requirements.

THE MEMPAC-M STANDARD
One series.
One standard of quality.
Phased, expandable MEMPAC-M systems are grounded in the same Cloacina principles found throughout the series: proven pre-engineering, quality materials and components, integrated equipment and controls, factory installation and wet testing, and single-point responsibility.
SHARED PRINCIPLES
Proven Pre-Engineering
MEMPAC-M systems are extensively refined and informed by real-world operating experience. Pre-engineering helps reduce project risk, support consistency, and streamline design and production.
Quality Materials and Components
Stainless-steel tankage and corrosion-resistant components support durability, quality, and long-term system performance.
Integrated Equipment and Controls
Treatment equipment, controls, monitoring, and operator-access features are integrated into a coordinated packaged system.
Factory Installation and Wet Testing
Equipment is installed and wet-tested at Cloacina’s manufacturing facility before shipment, supporting quality control and reducing field integration.
Single-Point Responsibility
Cloacina provides an integrated treatment solution supported by technical expertise, operator training, remote support, and lifecycle services.
TREATMENT PROCESS AND PERFORMANCE
Advanced treatment. High-quality effluent.
MEMPAC-M systems combine activated sludge treatment with membrane clarification. The membrane barrier retains suspended solids within the biological process, producing high-quality effluent.
The systems incorporate Cloacina’s Forward Activated Sludge process to provide the motive force needed to maintain appropriate viscosity at the membrane interface.

Lower effluent limits may require additional engineering and process equipment. Final treatment requirements and system configuration are project-specific.
OPERATOR-CENTERED BY DESIGN
Designed by operators, for operators.
Cloacina MEMPAC-M systems are informed by decades of hands-on wastewater operations experience. Equipment access, controls, monitoring, redundancy, and maintenance are considered as part of a complete system so operators can work safely and efficiently.
Accessible Equipment Layout
Equipment is arranged to support visibility, accessibility, and routine maintenance while minimizing unnecessary disruption to plant operation.
Cloacina Slide Rail System
Sensors and submerged equipment are mounted on Cloacina’s Slide Rail System, providing safe, repeatable access while reducing cord tangling and physical strain.
Advanced Controls and Monitoring
Intuitive controls, Human-Machine Interface access, process monitoring, trending, and remote support give operators better visibility into system performance.
Membrane-System Redundancy
Independent membrane trains and redundant equipment support maintenance and cleaning while helping preserve treatment capacity.
Automated Foam Control
Integrated foam-control features help manage buildup and reduce the need for operator intervention.
Specific features and equipment may vary by model and project configuration.
