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.
For years, the wastewater treatment plant in Villa Mercedes, David City, Panama emitted harsh odors and created a rampant mosquito population, a situation the neighboring residents found impossible to deal with. Treatment at the plant needed improvement to successfully treat up to 4.6 million gallons of wastewater per day, eliminate harsh odors and reduce the mosquito population.
A WWTP chooses a new screw press that takes up less than half the space that the old belt press had occupied. This was striking for the operations team but not as striking as the fraction of time they needed to spend managing the screw press.
Olayan Voltas Contracting Company was awarded the 2013 “Sustainable GCC Project-of-the-Year” by MEP Middle East magazine for the utility complex at Al Bustan Village, a brand new residential community north of Riyadh, Saudi Arabia.
Veolia faced the daunting challenge of managing two large WWTP’s as well as finding a better and more cost effective solution for odor and corrosion control.
Lake John Hay is located six miles northwest of Salem, Indiana and is used for drinking water and tournament and recreational fishing. With an average depth of 14-15 feet, it is ideal for algae and plant growth. The persistent, recurring algae blooms was causing taste and odor problems, which led to frequent complaints.
FluenceTORNADO® Self-aspirating surface Aerators and submerged Diffused Air Systems helped to rejuvenate the Laguna Niguel fresh water reservoir in Southern California. The aerators removed the algae and odor problems naturally, and kept the oxygen content of the water high enough to support a profitable fishing industry.

To protect the environment, wastewater treatment facilities across the country are required to deliver dissolved oxygen (DO) into the treated effluent, with most DO permits ranging from 2 to 10 mg/L.
Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.
The Village of Johnson Wastewater Treatment Facility (WWTF) was among the first in the state of Vermont to meet newly enacted secondary treatment requirements when it began operation in 1970.
The City of Reno, NV, has long battled the buildup of fats, oils, and grease in the wetwells of wastewater lift stations in the valleys within this high desert city. Recently, the city set out to address the problem and reduce the associated costs.
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.
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.
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.
The BCS Odor Control Systems are larger bulk media systems, designed for higher air flow rates. 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 6,800 cfm (11600 m3/h) in a single carbon stage and up to 20,000 cfm (34000 m3/h) in a dual bed 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.
Ecosorb® 5000S is a broad spectrum odor neutralizer which reduces emissions for specific gases including hydrogen sulfide, mercaptans, amines and thioethers. Ecosorb 5000S can be diluted with water or used neat depending on application and delivery equipment to remove odorous compounds including acids and bases.
