Product Overview
MPAC™ Systems:
Custom Systems
THE SYSTEM
Simple in design and easy to operate, an Enviroquip
MBR System provides the benefits of membrane technology without
the
complexity. From point-of-use package plants (see MPAC™ Brochure) to custom municipal installations, Enviroquip
has designed and/or commissioned over 100 MBR facilities. Our
experienced staff of professionals is trained to help you
customize your plant using several available options as
shown
in the diagram below. 
MPAC™ Systems
For small systems ranging in capacity from 5,000gpd to 125,000gpd,
Enviroquip offers a series of pre-engineered, pre-assembled
package plants that can be constructed and installed in 4-7
months. Ideal for decentralized, point-of-use treatment, these
systems are easily “hidden in plain site” and provide
a superior effluent quality to conventional package plants.
Moreover, MPAC™ systems can be completely automated and configured
for remote monitoring and control.
Six MPAC™ models are available that include different features
and varying levels of instrumentation. Features common to each
model include:
- Flexible modular designs
- Superior effluent quality meeting
the most stringent reuse standards (Title 22 approved)
- Rugged
design for remote installations
- Easy to maintain and operate
- Options include equalization,
pre-treatment, disinfection, and sludge handling
- Proven,
standardized controls system designed for remote administration
A brief description of each model is provided below.
MPAC-S
The S model is available in either concrete or steel tanks
and requires some site assembly. Process equipment is skid
or tank mounted. S models are available as assembled pieces
or can be shipped loose for contractor field installation.
Features of this model include:
Pre-Cast Concrete Tanks
- Below grade installation
- Easy access to all process equipment
- Ideal for cold weather applications
- Field assembly required
Reinforced Steel Tanks
- Transportable above tanks for relocation
- Less field assembly
required
- MBR redundancy on all systems
MPAC-B
The B model is a self-contained modular system housed in a
pre-fabricated concrete building. This system is mounted
above grade and is equipped with all components necessary
for operation. Features of this option include:
- Plug-and-play” system further reduces any construction
costs and setup time
- Durable modular structure with multiple finish options
- Building air-conditioning available as an option
MPAC-C
The C model is a self-contained, easily re-locatable system
housed in a weather-tight ISO container. This system is designed
for use in extreme conditions and use as temporary treatment.
- Plug-and-play” system further reduces any construction
costs and setup time
- Durable modular structure with multiple finish options
- Building air-conditioning available as an option
Custom Systems
Medium (>125,000gpd) to large (>4MGD) scale MBR plants,
are custom designed to match the design criteria of each application.
However, Enviroquip has standardized design concepts for plants
in these size ranges that incorporate beneficial features from
our US installations as well as the 1,600 other Kubota MBR
plants operating worldwide.
For each of our standard designs, 3D scaled models are available
developed in Inventor®. Each model is fully compatible
with AutoCAD and provides detailed information regarding unique
piping and equipment requirements. In addition to our standardized
designs, Enviroquip routinely provides design support to engineers
developing unique layouts.
Process Types
UNR™
Using award winning bio-monitoring technology, UNR™ processes
improve energy efficiency and biological performance while
reducing system complexity.
Conventional
Not optimized for biological removal but sufficient for many
applications.
Primary Operating Modes
Gravity
Nearly 40% of the 1,800 operating flat-plate MBR plants operate
in what is referred to as gravity mode. In this mode of operation,
a few feet of water head above the submerged membranes is
sufficient to drive the filtration process. The primary advantage
of employing
this type of pump-less system is reduced maintenance. However,
not all applications are suited for a gravity operation and
require low head centrifugal pumps to drive the filtration
process. An example of a MBR System operating in gravity
mode is shown below.
Suction (Pumped)
Low-head pumps can also be used to drive filtration in lieu
of gravity. Utilizing pumps provides allows for pressurized
discharge to remote outfall or storage locations.
Options
STORM
MASTER™
This configuration provides a cost-effective means of handling
storm events and can significantly reduce solids handling costs.
This option also incorporates features of the Energy Pro configuration.
ENERGY PRO
Using an automated system of slide gates and specific plant
layouts, this configuration incrementally brings plant capacity
online to match demand and optimize energy efficiency.
STANDARD
Standard systems include few moving parts and are extremely
easy to operate. In fact, automation is optional for smaller
systems.
