Drinking water quality or better (e.g. RO permeate) is recommended as a basis for
cleaning solutions.
CIP frequency should not exceed 4 CIPs per year for each of the cleaning steps
mentioned above.
The CIP solution must be introduced from the feed side of the modules/membranes.
During CIP recirculation this will prevent any foulants and/or harmful substances
from
entering the filtrate side of the membranes.
A strainer must be installed to protect the membranes from particles which could
potentially damage them (max. pore size 300 µm).
Caution:
Please familiarize yourself with the relevant safety measures
for the storage and handling of the chemicals used in this
procedure.
10.
Permissible transmembrane pressure (TMP):

Filtration: max. 1.5 bar
 Backwash: max. 3.0 bar

Air Integrity test: max. 1.0 bar air pressure
Operating the membranes at any combination of the maximum limits of
temperature, pH, chemical concentration and/or pressure during production or
cleaning will have an impact on the membrane service life. The permissible
transmembrane pressures are not based on limitations in membrane strength, but
simply on good operating practice for UF membranes. Compaction of fouling layers
on the membrane surface should be avoided to enable stable long-term operation.
The burst pressure of the Multibore membrane is higher than 10 bar.
11. Substances that may cause damage to the membrane or irreversible membrane
fouling:
Do not subject the membranes (feed or filtrate side) to elevated concentrations of
oil, grease/fat or other elements of organic or inorganic origin that could result in
the chemical or physical destruction of module integrity or irreversible membrane
fouling. Ensure that the modules/membranes do not come into contact with polar,
organic solvents, chlorinated solvents or concentrated acids/bases at any time.
Modules/membranes in the system that have been irreparably destroyed or
irreversibly fouled by the substances cited above are not covered by the inge
warranty.
