On-site Installation & PVC Media for Engineered Trickling Filter Applications
The Biomedia System from SPX Cooling Technology’s Marley brand uses SPX’s extensive experience in manufacturing cooling tower PVC film fill to produce PVC media for fixed film trickling filters
Quality, cost and project timescales are optimised through proven ability to manufacture filter media. By offering simple, high-performance solutions for new or expansion projects, construction services are an integral part of SPX’s abilities.
The Marley Biomedia System uses modular, PVC corrugated MARPAK® media that is specifically designed for biological treatment applications. This media offers resistance to rot, fungi, bacteria, acids and alkalies and is installed using the specialised MARPIER™ support system which can be adjusted to accommodate different floor slopes.
Marley Biomedia systems can also be fitted with custom grating and deck solutions that offer long life, easy maintenance, and safe operating in harsh environments through their strength, rigidity, corrosion resistance and lightweight structure.
The innovative and cost effective MARDEK™ and MARGRID™ composite fibreglass grating products can be utilised for media support, and for top protection and walking surface.
MARDEK pultruded grating is used where support spans require a high-strength solution. MARGRID is a fully customisable product with options available to meet specific site requirements including non-slip grit, and choices for open percentage, height, resin type and colour.
Through its Marley brand, SPX’s experience on-the-site installation and PVC media means it can engineer solutions for all types of trickling filter applications including complete secondary treatment, nitrification, denitrification, industrial roughing filters and anaerobic treatment.
Its proven skills in onsite construction services help to avoid potential issues during the construction phase. Overall SPX Marley Biomedia Systems can be designed to meet specific application needs and have been shown over the years to provide consistent high-quality performance and long life.
