ODOR CONTROL RESOURCES

  • Sludge Thickeners: The Good, The Bad, And The Smelly

    Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome.  These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal.  Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.

  • Is There A Cure For Wastewater’s Summertime Blues?

    As we approach the hottest months of the year, wastewater treatment plant (WWTP) operators face a range of challenges arising from elevated summer temperatures. With all due respect to Eddie Cochran, this article outlines some of the cures — or at least preventive steps and countermeasures — for wastewater treatment’s “summertime blues.”

  • MABR Is The Big Cheese For This Dairy Farming WWTP

    Hayogev is a residential development in the rural area of Jezreel Valley, with 1000 homes, agricultural fields and dairy farms. Located in an open field next to small farms, the local treatment facility handles wastewater from HaYogev and Midrach Oz. The customer was looking for a localized wastewater treatment solution to replace the existing pond system, which faced difficulties in treating the wastewater due to high levels of nutrients. A new state-level regulation concerning reclaimed water required the wastewater treatment plant (WWTP) operator to reduce the nutrients in the effluent stream. The solution had to be odorless and quiet, have low power consumption, and use the existing pond and structure.

  • Cardston’s Community Relationship Improves With Dewatering Technology Choice

    Cardston WWTP’s choice of a dewatering system to replace its belt press, Huber Technology Q-Press®, has a striking comparison to the plant’s previous technology in both the footprint and the attention it requires. The Cardston staff also noticed striking improvements in water separation, end-product dryness and offensive odor by-product.  Read more about how the Q-Press® helped Cardston become a better neighbor.

  • Effective Odor Control In A Low Pressure Sewer System

    When the Metropolitan Government of Nashville and Davidson County received odor complaints from a residential subdivision, Evoqua provided a rapid, cost-effective solution.

  • Odor Problems Solved At Santa Margarita Water District’s Chiquita Water Reclamation Plant In Orange County, CA

    Santa Margarita Water District (SMWD) is the second largest water district in Orange County, California, providing water and wastewater services to more than 155,000 residents and commercial enterprises. When a new housing development was planned adjacent to SMWD’s 9.0 MGD Chiquita Water Reclamation Plant, the District initiated plans for enhanced odor control solutions. District staff identified the primary process area (grit removal and primary clarifiers) as a significant contributor to odor emissions.

  • The Biology Of Biofiltration And Odor Control

    Each industrial odor problem is as unique as the processes and materials that combine to cause it. While various methods are employed to control industrial odors, biological treatment solutions hold a great deal of promise. This article examines what goes on inside a biotrickling filter and aims to equip facility managers with the information they need to make better industrial odor control decisions.

  • I-BOx® 6000 Biological Odor Control System Removes Odors From Laguna SOCWA Lift Station

    After decades in service, the wet well at the Laguna Southwest Orange County Wastewater Authority (SOCWA) lift station became dilapidated. The project included a hybrid manhole/junction structure that would also serve as the bypass wet well during the rehabilitation work. Upon completion of the wet well rehabilitation, the temporary sewage bypass pumping system was removed and normal lift station operation was restored.

  • Identifying Odor Control Needs In Manufacturing Operations

    Odor problems at manufacturing facilities can be unexpected, and can work against the production the facility is meant to accomplish. It starts out as a nuisance or a non-compliance issue, but can become a much bigger problem. Solving the problem requires analyzing how a facility’s processes generate and disperse odorous air, and then identifying an appropriate odor control solution.

  • Wastewater Facility In Missouri Tackles Foul Wastewater Treatment Odors Safely And Effectively

    Serving nearly 16,000 customers, a large-scale wastewater treatment facility in Missouri manages a complex sewer system, and has to contend with regional growth where more residential houses and commercial facilities have been built close to the facility. As a result, foul odor complaints from neighbors continue to increase, and the local town council found itself in need of fully addressing this issue.

ODOR CONTROL SOLUTIONS

  • Mapping And Identifying The Source Of Water Quality Issues

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  • Ecosorb® Spray Gel®

    A special spray gel formulation of Ecosorb® odor eliminator topically encapsulates material, blocking odors from escaping into the atmosphere. Ecosorb® Spray Gel® is an ideal solution for sludge handling and transportation, open-bed waste trucks, working faces of landfills, soil remediation projects, and other solid/semi-solid odorous materials that continuously emit odors.

  • Carbon Odor Control Systems - MCS Series

    The MCS Odor Control Systems are single stage, skid-mounted, dry media systems, designed for relatively lower odor levels and organic odors. The media may be virgin activated carbon or any of a number of specialty catalytic carbon media. Standard models are available to treat up to 1,400 cfm (2400 m3/h) of odorous air.

  • I-BOx® Biological Odor Control Systems

    The I-BOx® Biological Odor Control Systems (patent pending) use a two-stage process with a biological stage to remove 99% of the hydrogen sulfide (H2S), followed by an activated carbon polishing stage to remove residual H2S and organic odors. Standard models are available to treat up to 5,000 cfm (8500 m3/h) of odorous air.

  • 4632 Chlorine Dioxide Analyzer System

    The Signet 4632 Chlorine Dioxide Analyzer System is an integrated all-in-one system designed to measure Chlorine dioxide residual up to 2 ppm/mg/l.
