Regardless of whether you need to eliminate odors generating public complaints or protect personnel and infrastructure from hydrogen sulfide, ORIN Technologies can provide you with solutions to meet your goals.  We have experience in nearly every biological water treatment process utilized in municipalities and industry, often under difficult circumstances.  ORIN’s patented advanced oxidation process, AOTech, affords us the ability to treat even the most complex odor compounds efficiently and economically.  Our expertise and experience allows us to apply the process where minimal contact time, high oxygen demand, a blend of odor compounds, or economic challenges of traditional odor control methods exist.  Application of the AOTech process is designed to minimize cost, ensure compatibility with existing biological treatment, and deliver results without harming the environment.

ORIN personnel have experience working with a wide range of odor control processes, including AOTech, traditional oxidants, sequestering agents, scavengers, encapsulants, odor neutralizers, etc.  This experience allows us to select the best option for addressing your odor issues.
