Suction-Scanning Screen Technology

Fast, Efficient Self-Cleaning Technology for Continuous Flow of Filtered Water

Amiad’s greatest achievement is its research, development and the production of suction-scanning screen technology. Suction-scanning technology combines focused flush with automation to provide 100% cleaning of the screen area. The success of this technology has established Amiad as a global leader in providing water filtration solutions.

Amiad suction-scanning filters incorporate a unique multi-layer stainless steel screen available in degrees of filtration as small as 10 micron. Amiad’s engineering team has developed the optimal combination of material strength; filtration efficiency and clean-ability by combining select ratios of screen weave type and patterns, resulting in a high efficiency of filtration. This sophisticated screen assembly allows the accumulating filter cake to be rapidly and totally removed. Amiad’s suction-scanning technology uses less than 1% of the total process water for cleaning. This is the lowest ratio of process to exhaust water of all competing automated self-cleaning methods. (This ratio can vary depending on specific application conditions).

The self-cleaning cycle is triggered by the accumulation of suspended solids (filter cake) on the screen surface, as measured by the pressure differential. Therefore, cleaning is performed “as needed” – resulting in minimal water and energy waste. Suction-scanning technology eliminates the need for isolating the filter during the self-cleaning cycle. This focused cleaning and the minimal exhaust requirement allow for uninterrupted process flow.
