Pressurised and Submerged membrane modules are used for a wide range of applications. The details and application information for each module type are shown in the following pages.
ultrafiltration membrane is a sieving process that utilizes membrane (nanometer-level) separation technology. Driven by the pressure difference on both sides of the membrane and with the ultrafiltration membrane as the filtering medium,numerous tiny micropores densely distributed on the surface of the ultrafiltration membrane only allow water, small molecular substances and dissolved solids
to pass through and become the permeate, while substances in the original liquid whose volumes are larger than the micropore diameters on the membrane surface are retained on the inlet side of the membrane and become the concentrated liquid. Thus, the purposes of purifying, separating and concentrating the original liquid are achieved. The filtration precision of ultrafiltration ranges
from 0.002 to 0.1 micrometers, and the molecular weight cut-off is between 1,000 and 100,000.
R-30 is a microfilter liner used to clarify beer. The liner operates in cross-flow mode and requires regular backwashing and SIP cleaning in accordance with the schedule established by the system supplier.
The module is available in the form of an insert, its stainless steel housing is part of the BMF membrane filtration system for beer. When installing a module, you must follow the instructions compiled by the supplier.

[1] This temperature may affect the service life guaranteed by the supplier
- The quality of cleaning solutions should meet permeate quality or higher
- Washing system pumps must be made from non-corrosive materials
- To avoid mechanical damage, do not expose the membrane module or element to sudden temperature changes. Do not exeed the temperature threshold specified by the installation manufacturer. During heating or coolong, do not exceed the maximum speed of 3ºC/min. When the system temperature is above 35ºC. Failure to do so may result in irreparable damage.
- To avoid mechanical damage or leaks, never alliw water hammer to occur in the system.
Detergent Resistance
Operating membrane modules at any combination of the maximum pH, chemical concentrations, pressure or temperature specified in the documents provided by the installation supplier, during cleaning or during production, may affect the membranes and/or module life.
Launch
- Before starting beer filtration, new membranes must be washed through a full CIP washing cycle
- In any case, the use of grease or oil based lubricants should be avoided.
