MBR Placement
This section describes module layout in the membrane tank and required water depth.
C AU T I O N
When using this product, ensure that all of the installation requirements below are met. If these
requirements are not met, the product will not function as indicated in the specifications, and/or may
deteriorate or become damaged.
Integrated MBR systems require membrane tanks with a capacity that ensures the HRT (hydraulic
retention time) required for biological processing.
The diffusers are used for biological processing, membrane scouring and in-tank mixing. Make sure
that the diffuser equipment (blower, pipe diffuser, etc.) is suitable for all of these uses.
Place the inlet for raw water as far as possible from modules to prevent undecomposed raw water from
coming into direct contact with modules. Otherwise the undecomposed parts of raw water can cause
coating and fouling of the membrane which increase the rate of clogging, resulting in unstable
operation.

Module Layout
When placing modules in a membrane tank, it is necessary to maintain enough space for sludge moved
upward through the modules by aeration to move downward.
Maintain the following depthwise center-to-center clearance. (See Figure 1-4)
For modules using 56E0040SA elements: 2.2 m or greater (distance to the wall: 1.1 m or greater)
Maintain enough widthwise clearance for pipe placement etc.
C AU T I O N
A lack of sufficient clearance will prevent stable operation.
