Industrial air filtration: A sustainable approach to industrial emissions control

The article explains how combining biological and adsorbent technologies for industrial emissions can provide performance and low long-term operating costs. Meeting air permit requirements is essential first to allow construction of an industrial facility and then to its continuing ability to operate. Effectively managing industrial emissions is essential to the growth and profitability of virtually every manufacturing activity. In total, the technologies employed should have a low initial cost, but more importantly, have low long-term operating costs, as this latter component of cost will often make up the majority of the investment in a solution. Biological treatment is ideally suited for contaminants that are low molecular weight, water-soluble, polar and readily biodegradable. Aldehydes, ketones, alcohols, ethers, esters and organic acids degrade rapidly in biofilters. Halogenated organics are not good candidates for biofiltration. Biofiltration is a proven, reliable technology for control of VOCs and odor with high removal ratios. The systems offer simple operation with minimal maintenance requirements.
