A Chilean Wastewater Treatment Plant Combats Odors and Keeps Neighbors Happy


Source: OMI Industries (OMI)

The climate in Northern Chile can fluctuate between very warm and cooler temperatures. As a result, for wastewater treatment plants in the region, there is the ongoing challenge of foul odors making their way towards neighboring residences – especially during the hotter months.

For the Aguas del Altiplano’s wastewater treatment plant in Alto Hospicio, Chile, this odor challenge became significant issue, resulting in a number of complaints from neighboring residents. Aguas del Altiplano is the largest private company in the region that provides both drinking and wastewater treatment solutions for residents and the local government.

In particular, the plant’s facultative lagoons are surrounding by residential neighborhoods. It was clear Aguas del Altiplano required an odor mitigation solution that was both effective and safe for both employees and residents.

Aguas del Altiplano did extensive research on a number of odor mitigation solutions and opted to install an OMI Vapor Phase 1200 CFM system for the perimeter around the facultative lagoons, which was 150 x 110 meters.

The new system generates sub-micron sized droplets of the Ecosorb® 606, which are dispersed throughout the perimeter using a PVC header system. Ecosorb® odor control products effectively neutralize odorous compounds. Without the use of masking fragrances, the products are a proprietary blend of plant oils, food grade surfactant and water – making them safe for everyone.

After the new system was installed in February 2016, the results were immediate. The OMI Vapor Phase 1200 CFM system was able to easily neutralize odorous gases, such as hydrogen sulfide, which resulted in much happier neighbors.

OMI Industries will be attending WEFTEC 2016, where we will be announcing a new offering for the wastewater treatment arena. For all attendees, please be sure to stop by booth #2009 to learn more.
