The 2″ Spin Klin™ disc filter by Amiad is an ideal solution for water treatment applications that require stability, precision, and cost-effectiveness. The following sections provide in-depth information to help you better understand the operating mechanism, technical features, practical benefits, and application scope of the system.

1. Operating principle of the 2″ Spin Klin™ disc filter

The Spin Klin™ 2″ operates based on a depth filtration mechanism using multilayer polymer discs with intersecting grooves. As water passes through these disc layers, contaminants are trapped at the intersection points, allowing only clean water to continue flowing.

During the backwash cycle, water or air pressure is used to release and separate the discs, flushing out all accumulated debris. The system can be configured to backwash using an internal source, external source, or a combination with compressed air for enhanced cleaning efficiency.

The detailed working principle is demonstrated in the following video, which we invite you to view:
