7. Lifting Procedure
Follow these procedures when lifting the “NHPA Series” modules for maintenance.
(1) If guide rail system is not installed in the membrane tank, drain the activated sludge from
membrane tank.
(2) Disconnect the manifold from the filtrate water line and disjoint the bolts jointing the
element block with the aeration block in case bolts/nuts are applied for connecting both
blocks.
(3) Hook the chain/sling attached with element block to the lifting device, and you can lift up
the element blocks using chains/slings. Connected two (2) element-decks can be lifted
up at one time.
(4)
Use guide rails certainly and do not connect three (3) element-decks or more when
installing taller module NHPA150-3C and 4C. Also do not lift entire decks at one
time. The upper/lower element block must be lifted one by one to avoid distortion
or damage to the element block which may cause severe accident. See the
instruction below.
Attach chains or slings to the lifting lugs when lifting element-deck,
element block or aeration block of “NHPA Series”. Slowly raise the
module straight up. Avoid sudden changes in movement to
minimize shaking the module. Never allow personnel to stand
under the “NHPA Series” during lifting.
Never lift or operate the module with worn or damaged parts. Use
chains or slings rated for the weight being lifted. Check the
condition of each part before lifting.
Do not lift upper element block and lower element block at once as
one unit when lifting NHPA150-3C or 4C. Lift the upper and lower
element block separately.
Wear the appropriate personal protective equipment (e.g. safety
gloves) in order not to cut hand on the edge of the module frame.
