Take adequate measures during the installation process to protect the
“NHPA Series” from sparks emitted from welding equipment, fusion cutting,
or grinding.
Protect “NHPA Series” from freezing at all the time.
Avoid pressurizing the filtrate side of "NHPA Series”.
Install the screen with openings of 3.0 mm or under before the membrane
tank. Mesh type screen is recommended. Overflow or waste carryover must
be avoided at all the time.
Connect the flanges of filtrate water manifold to the piping with the tightening
torque of 20 N.m, in order to avoid distortion, leakage, or breakage of the
filtrate water manifold.
Consider piping materials and regulate the load to the flange connection
points at less than 20 kg per flange in order to avoid distortion, leakage, or
breakage of the filtrate water manifold. If the load exceeds the limit shown
above, put some supports on the piping to reduce the load.
2. Safety Instruction for Operation and Maintenance
Filtrated water is not for potable uses. Do not drink the MBR filtrate.
Before discharging the treated water to the environment or reusing it, make
sure to analyze its quality and confirm that the water quality meets the
intended purpose.
Do not burn the membranes without appropriate facilities since harmful
Hydrogen fluoride (HF) gas will be generated. Hire a professional solid
waste disposal company to perform the task when disposing of the
membrane elements.
