Exposing the “NHPA Series” and membrane elements to
temperatures above 40 deg C or direct sunlight should be avoided.
Exposure to direct sunlight/UV radiation will cause the
polypropylene filtrate water manifold to deteriorate.
Protect “NHPA Series” from freezing.
Take adequate measures to protect “NHPA Series” from sparks
caused during welding, fusion cutting, or grinding.
Take precautions to protect the elements from damage. Do not
place heavy objects on the module. Protect the module from
potential collisions with other moving objects.
Be careful not to damage the rubber parts of air diffusers and
element fixing brackets.
5. Installing Products
Check the followings before module installation:
(1) Make sure all necessary work in the membrane tank has been completed.
(2) Make sure the tank and all pipes have been thoroughly cleaned and free of debris.
(3) Confirm that there are no leaks in any of the tank and water or air lines.
(4) Using clean water in the tank, check the operation of major equipment components
such as: pumps, blowers, sensors, and control systems.
Review the drawings in the REFERENCE to make certain final tie-ins to the “NHPA Series”
are as per the drawings. Refer to the information in the REFERENCE if you intend to install
the module without anchoring the module to the floor of the tank (e.g., using guide rails
instead).
(1) Installation of Aeration Blocks (on the bottom of the membrane tank using anchors)
First install the aeration blocks in the membrane tank using suitable anchors. If multiple
aeration blocks are to be installed, record each block’s serial number and position within the
tank.
The air diffusers should be installed in a horizontal position to achieve uniform
scouring aeration.
The maximum allowable deviation from the dead level for the air
diffusers is 3/1,000 on the top surface of the aeration block in both lateral and vertical
directions.
(2) Plumbing in Air Diffusers
Prior to plumbing in the air diffusers, flush all pipes out. The air diffuser should be connected
