The hydraulic disks of the Amafilter PM disk module system guarantee optimum flow across the membrane surface, even for the most complex tasks. This substantially reduces performance-diminishing fouling and scaling of the membrane. The result is a higher specific permeate performance. Due to the open flow channel, even media containing solid substance can be directly processed without the necessity for complex pre-filtering. Because of the flexible structure of the disk system, with elements arranged in series and parallel, flow can be optimised even for viscose media. The PM module is supplied in three varieties, with one each in industry, pharmaceutical and foodstuffs standards.
