Air Stripping of Odor Matters.

Treating Ventilation Exhaust Air for Odor Control

and Implications Odor control for swine facilities has focussed on storage and the land application phases of manure handling. A third component, ventilation exhaust air, has received little attention. This research was targeted at reducing odor emitted from ventilation exhaust air by filtering odor carrying dust particles. The ultimate objective is to develop a system that could be implemented...

Laboratory Studies of Air Stripping of VOC-Contaminated Soils

Bench-scale laboratory experiments were conducted to evaluate the effectiveness of air stripping for in situ remediation of benzene-contaminated soils. Several parametric studies were performed to evaluate the effect of soil grain size, air injection flow rate, and air inlet temperature on the benzene recovery efficiency. An increase in soil grain size produced a significant increase in benzene...

Overview of Odor Detection Instrumentation and the Potential for Human Odor Detection in Air Matrices

John J. Sheridan, DDS, MSD, on air-rotor stripping.

DR. SHERIDAN Prior to ARS, there was ab solutely nothing in the literature pertaining to stripping the proximal surfaces of buccal teeth, because for decades we banded them and these surfaces were covered with metal. That changed abruptly when bonding became the standard. All proximal surfaces became approachable and, therefore, strippable during any stage of treatment. Also, traditional stripp...

Air Pollution and Odor in Communities Near Industrial Swine Operations

BACKGROUND Odors can affect health and quality of life. Industrialized animal agriculture creates odorant compounds that are components of a mixture of agents that could trigger symptoms reported by neighbors of livestock operations. OBJECTIVE We quantified swine odor episodes reported by neighbors and the relationships of these episodes with environmental measurements. METHODS Between Sept...
