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.
Henrico County, Virginia (The County) utilizes multiple chemical technologies in the sewage collection system in order to control hydrogen sulfide concentrations at key points within the system. The county has strict compliance limits for hydrogen sulfide and was facing growing costs, spending in excess of $1.8 million dollars in 2010.
Almost all wastewater collection system odor and corrosion problems are a result of the formation of sulfide. Sulfide is formed under the anaerobic conditions that typically exist in wastewater force mains.
When a Mid-Atlantic water authority received complaints about odor, corrosion, and safety issues, Evoqua replaced a liquid bleach system with a nonhazardous, comprehensive solution for effective odor and corrosion control.
Evoqua’s team of engineers and scientists is widely recognized as the most experienced and authoritative body of odor and corrosion control specialists assembled within any vendor organization worldwide.

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.
