The Compact Monafil zero-energy biofiltration system from Anua uses specialized media for the removal of odors, VOCs, sulfur and nitrogen-based compounds. The properties of the granular high-density peat media have proven to be a key factor in achieving high-performance removal and extended media life, according to Anua. It also uses recycled shell-based media to maintain a neutral pH within the prepackaged biofilter. The peat and shells ensure optimal odor control while simplifying operation and enhancing system reliability. It is based on technology used successfully for more than 20 years in odor control applications. 800/787-2356; www.anua-us.com.
