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.
Alfa Laval PilotUnit Combi-50 RO/NF
The Alfa Laval PilotUnit Combi-50 RO/NF is a handy and versatile pilot-scale membrane system comprising an Alfa Laval plate-and-frame module M30 complete with necessary pump, valves, tank etc. It needs only power supply, compressed air, water and feed product to operate.
