ODOR CONTROL RESOURCES

• Bench Test Instructions For Your Case Study

  Natura Solve provides a complex liquid medium that is produced via a proprietary fermentation process. It consists of a selected spectrum of naturally occurring microorganisms, sustained within a matrix of micro elements and macro elements that provide the critical building blocks for respiration and growth. Thus it simultaneously works as both a biocatalyst, stimulating endogenous bacteria metabolic and production rate and a specialized delivery medium for the highly effective bacteria. The formula is very aggressive due to the essential balance between the selected groups of microorganisms, which, when combined with the enzymes they produce, synergistically create catalyzing proteins that significantly speed up the biochemical reactions and natural decomposition processes of the organic material into humic matter.

• Wastewater Collection And Treatment: General Observations

  In this discussion, I am going to discuss general issues in wastewater treatment and specifically the collection phase of waste treatment. We all realize the effort and expense that goes into treatment-plant technology, but many don’t seem to realize that the collection phase is where we get “more bang for the buck.”

• Reducing H2S And FOG At The Discharge Of A Force Main

  Beginning early in 2019 our office began receiving complaints of sewer odor in the neighborhood of Fountain Ridge Section III (FR III), located in Prince George County VA. The County Operations staff investigated the wastewater collection system that serves the neighborhood, and found that odor was proliferating throughout the neighborhood. Corrosion of the sewer manholes was clearly evident.

• Mixing Made Easy For Low Energy Lakes, Ponds, And Lagoons

  Landlocked, shallow bodies of water such as recreational ponds, irrigation, drinking water and animal waste lagoons have a major problem with flow. The only natural methods of movement in these bodies of water are the slight Coriolis Effect of the earth and wind. Neither of these natural mixing sources is sufficient to allow shallow water bodies to respire and deal with the natural biological degradation of wastes and detritus that eventually form on the bottom. Eventually, external problems will occur – algae begins to form in abundance, odors will emanate from the water due to stagnation, blue-green cyanobacteria will form on the surface and cause more odor and toxicity, and eventually the water is no longer capable of supporting basic aquatic fauna reproduction.

• 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.
