The Alfa Laval AS-H Iso-Disc cloth media filter enables production of high-purity, reuse-quality filtrate from applications such as tertiary filtration, process streams, surface water treatment and other water reuse. The robust yet simple filter design can handle solids and hydraulic loading with a small footprint-to-flow ratio.
Performance of the Iso-Disc cloth media filter is second to none. The cloth media is capable of solids capture down to 10 microns without having to build up a filter mat or require any run-in time. The two-layer pile cloth allows for complete cleaning during backflush, utilizing filtered water from inside the filter plate. If required, the cloth media can be replaced and the filter plate re-installed in a matter of minutes, all while the filter continues to function without interruption.
The gravity driven, continuously operating filter uses completely submerged filter media, which gives 100% active filtration area all the time. The outside-to-inside flow through the pile cloth media provides much better depth filtration compared to screens. All internal or submerged components are corrosion-resistant stainless steel or non-metallic materials. For retrofits, the square or rectangular filter plates easily fit into existing basins and require only a low driving force of 30 cm water column.
