Module M30

The Alfa Laval module M30 is specially designed for reverse osmosis (RO) and nanofiltration (NF) tasks. Its unique features makes the M30 module from Alfa Laval the ideal choice for a large number of applications within the dairy, food, chemical, pharmaceutical, pulp and paper industries and for water treatment

Gets the water out

Where water removal or recovery is concerned, reverse osmosis is a superior method. Pure water can be separated from dissolved salts and solids. In a continuous mode, on a large scale and in a cost effective way.

Heat-sensitive products such as egg white, amino acids, pharmaceuticals, diluted foods and beverages can be concentrated at low temperatures. The costs are much less than for other, traditional processes - often the energy savings are as high as 50% compared to for example spray drying.

Plate-and-frame module, M30

The standard Alfa Laval plate-and-frame M30 module is made of stainless steel and rugged polymers. Held together by a single central bolt, this sandwich of spacers and membrane-covered plates is designed in a way that membrane flow channels form under hydraulic pressure.

The basic module is the same for all industries. However, the Alfa Laval module M30 can be scaled up or down and fitted with pumps for any purpose. This makes the M30 the ideal choice for a large number of applications within the dairy, food, chemical, pharmaceutical, pulp and paper industries and for water treatment.  

 The Alfa Laval module M30 is available with membrane area sizes up to 19 m² and it can operate at pressures up to 60 bar at 40°C and pH up to 9 (up to 12 for CIP). It can be equipped with the entire range of flat sheet reverse osmosis and nanofiltration membranes available from Alfa Laval.

  • easy cleaning by CIP (Cleaning-In-Place)
  • low internal volume
  • easy membrane failure detection and exchange
  • low energy consumption
  • chemical and thermal tolerances set by the membranes and the type of plate material
  • concentration of heat sensitive and low molecular weight solutions

How it works

M30 GA drawing

The plate-and-frame module from Alfa Laval is designed with open channels across the membrane surface. The feed stream/retentate flows through these.

The membrane itself is supported by hollow plates with numerous slots that allow the permeate to collect and be removed from the module via the permeate collecting tubes.

Plate-and-frame modules use the membrane itself, aided by lock rings or strips, to seal off the feed/retentate from mixing into the permeate channels. This also prevents any leaks from the plate stack itself.

Plate-and-frame membrane replacementDue to the design of the plate-and-frame modules from Alfa Laval, individual membranes can be replaced without affecting the other membranes of the module.

Customized solutions through flexible design

Alfa Laval membrane equipment is designed on a modular basis that gives a high degree of flexibility, as membranes are built into modules, modules are built into loops and loops are built into systems.

The design of a system can thus be customized to meet any process needs and it is easy to expand, if production requirements increases. This means that your investment can follow any required increase in production capacity, as and when you need it - and at a relatively low additional cost.
