Cloth media filter for wastewater treatment
Achieve reuse-quality water with continuous filtration, even during backwash, through a high-performance cloth media filter that captures solids down to less than 10 microns.
Captures and Polishes Wastewater for Reuse
The AS-H Iso-Disc from Alfa Laval is a cloth media wastewater filter designed for municipal and industrial applications. Its unique cloth media captures solids down to less than 10 microns, delivering reuse-quality and Title 22 certified water. Operating on a continuous and fully automatic basis, it ensures uninterrupted filtration with a gravity-driven, outside-to-inside flow through submerged media, maximizing the active filtration area. This system is commonly employed in applications like municipal and industrial wastewater treatment, water reuse, and surface water polishing, resulting in treated effluent and polished water. Its robust engineering features corrosion-resistant stainless steel or non-metallic materials, suitable for various operational environments. The Iso-Disc fits easily into existing basins with minimal retrofitting, requiring just a 30 cm water column for driving force. Moreover, its maintenance is streamlined through individual filter element monitoring, quick plate removal for sampling, and efficient backwashing during operation. Configurable for expansion, it supports both square and rectangular configurations, adapting to various installation needs.
