RO spiral
Alfa Laval reverse osmosis spiral membranes (RO) are low energy, proven solutions for concentrating feed streams, particularly heat sensitive products. The RO spiral membranes can also be used for pre-concentration prior to evaporation as well as product and water recovery from permeate streams and evaporator condensate. The two series of RO membranes have different NaCl rejection properties. The RO membranes are thin-film composite cast on either polyester or polypropylene backing paper.
Proven design and membrane technology to enhance your RO process
- Cost effective operation thanks to low energy consumption
- Efficient – covering a broad range of salt permeabilities
- Minimal floor space required with its compact design
- Extremely durable – excellent chemical and thermal stability with service life up to several years
- Flexible – available in different combinations of length, diameter and spacer size
Alfa Laval’s experience with membrane technology is as long as membrane technology itself (more than 50 years). Based on our knowledge and experience with membrane technology, we offer two series of RO membranes with different properties to match your process and application The spiral membranes, which are manufactured in house at our own special facility, are based on a unique construction of either polyester or polypropylene support material in a sanitary full-fit design that provides optimum cleaning conditions. The reverse osmosis membranes are available as both flat sheet (for screening or lab work) and spiral (larger applications) which is an advantage when you scale up.
