Gas filter Cascade Filterpak®

for wastewater treatmentliquidwater

Veolia Water Technologies has developed a range of high-efficiency plastic media that provide the optimum effective surface area for biological growth whilst ensuring excellent gas and liquid distribution within the packed bed. Cascade Filterpak Media are ideally suited for use in traditional trickling filter applications and further complimented with a range of neutral buoyancy media specifically designed for use in Submerged Aerated Filters (SAF) Anaerobic reactors. Operating data from plants installed over the past three decades has enabled MTI to develop computer software that accurately calculates the required media volume for any specific municipal or industrial applications, thereby offering process security with a guaranteed high quality effluent. Benefits • Optimum bacterial attachment • Ideal effective surface area and void ratio within the packed bed • Guaranteed effluent quality • Controlled orientation within the reactor, ensuring optional three dimensional liquid distribution, increased hydraulic retention time and improved liquid film diffusion within the media bed • Designed for installation in a random orientation • Resistance to shock loadings, with fast recovery times • Material of manufacture: strong, lightweight, thermoplastic resin (polypropylene) • High aspect ratio (HAR) design • Robust, well-proven products • Suitable for wastewater treatment applications • Non toxic to micro-organisms • Immune to rot, fungus or bacterial attack • High resistance to ultra-violet degradation, ageing, erosion and disintegration • Recyclable material • No need for cutting or shaping to suit individual reactor profiles
