EnkaPack

Packing media for scrubbers and biotrickling filters

Industrial scrubbers and biotrickling filters play a vital role in air and wastewater treatment. They effectively reduce or even eliminate odor and manage pollutants such as hydrogen sulfide, ammonia or volatile organic compounds (VOCs). Both bioscrubbers and biotrickling filters rely on microorganisms such as bacteria to break down harmful components. To hold those microorganisms and support their growth, structured synthetic filter media deliver an ideal environment. They are also called structured packing media, fill media, film support or synthetic beds. With its open structure combined with a high specific surface, EnkaPack has proven to be a highly efficient filter medium. Therefore, the product is applied by an increasing number of international equipment manufacturers serving the air treatment and emission control industry.

This is EnkaPack

These are fused together where they cross and thus form a pyramid-shaped three-dimensional matrix.

Up to 95 % percent of the filter medium is open and available for the flow of air and water. Thanks to a high surface area per volume ratio, the fibrous structure efficiently supports the growth of a biofilm: a powerful layer of microorganisms.

How EnkaPack is used in odor control and VOC treatment systems

In scrubber or trickling towers EnkaPack is installed inside the tank units into which contaminated gas streams are fed. In both cases it facilitates the uniform distribution of gas and water. And it provides an excellent habitat for the growth of microorganisms like sulfide-oxidizing bacteria. EnkaPack is compression resistant enough to effectively protect the biofilm from damage. This way, the medium ensures consistently high microbial biodegradation activity. Multiple layers can be stacked inside the tower without the risk of sagging and channeling. EnkaPack is inert to chemicals and organic solvents and reliably avoids clogging. What makes this film support stand apart from alternative synthetic packing media is its unique filament structure. EnkaPack provides up to 95 % of void space combined with a high specific surface area. Per cubic meter, microorganisms can grow on up to 650 square meters of filament surface. In bioscrubbers and biotrickling filters alike, EnkaPack so delivers a significant contribution to continuously high filter performance.

In addition to bioscrubbers and biotrickling filters, EnkaPack is also widely applied in humidifiers and demisters.
