Alfa Laval launched an upgraded version of its MBR membrane system at the IFAT exhibition held in Munich this year. The upgraded version has lower power consumption, is easier to service and can be installed with higher membrane density.
Reduced power consumption
Alfa Laval’s new aeration system, the S Aerator™, makes it possible to minimize the flow of scouring air and, in turn, power consumption in the blowers. The S Aerator™ has a single, Sshaped aeration tube that flushes itself automatically. In case of a blockage, air pressure builds up, eventually clearing and draining the tube. The S Aerator™ makes it is possible to aerate the membranes intermittently, thereby saving significant costs for energy, equipment and service.
Alfa Laval’s new QuickSwap™ technology facilitates membrane replacements and greatly reduces the time for service. Each QuickSwap™ cassette holds 85 membranes and can be replaced in one operation. During service, the tank level is lowered, the old cassette is removed, and a new one is inserted. Compared to replacing membranes and gaskets individually, there are substantial time savings with minimal risk of error.
The updated version of Alfa Laval’s MBR membranes only requires two free sides during operation, meaning it can be installed in rows. This roughly doubles the membrane area in a tank compared to an installation where membrane modules are installed with four free sides.
Alfa Laval’s MBR modules come in five different sizes and can operate utilizing gravity with as little as 1 m water overhead. This makes it possible to maximize the membrane density and capacity in tanks of all types and sizes.
