Evoqua Water Technologies’ water treatment system will save Washington County, Maryland, $16 million in upgrade costs, according to the county.
Evoqua will supply its BioMag ballasted biological treatment system to the county, which will enable it to meet strict Chesapeake Bay nutrient removal limits at the Conococheague Wastewater Treatment Plant. The $3 million contract will be the county’s third installation of this technology at its wastewater treatment facilities.
Julie Pippel, director of the county’s Division of Environmental Management, says the $16 million savings comes from reusing existing infrastructure with the BioMag System, which she says is more cost effective than building a new treatment plant.
The BioMag System infuses fine, fully oxidized iron ore particles, or magnetite, into biological floc to make it heavier, enhancing the clarification process. Evoqua says the water treatment system “uses the world’s fastest proven settling clarification technology for biological floc,” which it says allows capacity expansion and performance improvement with minimal plant modifications at low cost.
In addition to the Conococheague facility, Washington County’s Winebrenner Wastewater Treatment Plant in Cascade, and the Smithsburg Wastewater Treatment Plant in Smithsburg are also already using the BioMag System to meet the state’s new nutrient removal standards. The system will be operational at the Conococheague facility by the spring of 2018.
The state of Maryland’s Chesapeake Bay Initiative is intended to reduce pollutants, such as nitrogen and phosphorus, in the bay by 25 percent by 2025.
The company has also supplied its BioMag systems to municipalities in Virginia, Pennsylvania and West Virginia, Water World reports.
In a different region on the other side of the country, which is experiencing different water-related challenges, Evoqua is providing its water treatment technologies and services to the city of Paso Robles, California. Here the technology is intended to help the city attempts overcome water supply challenges due to the state’s ongoing drought. Evoqua’s UltraCarb 1240AW granular activated carbon media treats the Lake Nacimiento water supply for removal of total organic compounds, allowing the city to diversify its water supply.
The company also participated in the White House’s Roundtable on Water Innovation, along with other industry and public leaders, to discuss how to plan, efficiently use, and develop new supplies of clean water.
