MUNICIPAL WASTEWATER CASE STUDIES
|
|
 Columbia, Illinois WWTP
Columbia determined that a system upgrade was necessary because (1) the population served and the related daily flow rates were increasing substantially from approximately 0.65 mgd to 1.47 MGD and Columbia WWTP was reclassified to a major facility (2) discharge permit requirements for treatment were becoming more stringent from Total Suspended Solids (“TSS”) at discharge of 25 mg/L (from 45 mg/L) and Biochemical Oxygen Demand (“BOD”) at discharge of 20 mg/L (from 37 mg/L) and (3) Columbia was not consistently meeting discharge requirements. Without changed practices, compliance by Columbia with the even more stringent standards from Illinois EPA, at more than twice the daily flow rate, was regarded as improbable.

Larchmont, Georgia WWTP
Larchmont WWTP is owned and operated by Consolidated Utilies, a privately held company located in Savannah, Georgia. Larchmont determined that a system upgrade was necessary because the population served and the related daily flow rates were increasing substantially from approximately 0.3 mgd to 0.6 MGD. In addition, a more demanding and stringent discharge permit was implemented by the Georgia Department of Environmental Quality (GDEQ). |

Laurelville, Ohio WWTP
During 2000, the City of Laurelville determined that improvements were necessary and began active efforts to improve facility performance to benefit the environment and position the City for compliance with state and federal regulations and also the more aggressive standards of treatment that were expected for 2002 and thereafter. Laurelville also determined that if it could improve performance to the actual capabilities of their land area and infrastructure, the community may have an opportunity to treat municipal waste from an adjoining community and thus also lower overall per capita costs for Laurelville residents. |

INDUSTRIAL WASTEWATER CASE STUDIES

Frederick County, Virginia Landfill Leachate Lagoons
During 2003, Frederick County, Virginia felt that improvements to their Landfill Leachate Treatment Facility were necessary and began active efforts to improve facility performance for compliance with state regulations. Meridian engineers determined that for optimal performance an upgrade of the entire process was necessary. The design of our upgrade proposal focused on removal of ammonia nitrogen (NH3) at the requested flow volumes. Frederick County Landfill’s permit requirements were achieved with an AquaMats® Process upgrade that converted the current primary and polishing treatment lagoons into high performance bioreactors. |

AquaMats® Ammonia Piece
AquaMats® provide a 3D high surface area matrix consisting of fibers and open pore size areas to meet the complex set of conditions required to sustain colonies of nitrifying bacteria. This is vital because most ammonia removal/conversion below a pH of 9.5 is accomplished by colonies of microbes, particularly bacteria of the genus Nitrosomonas and Nitrospira. Without suitable surface area, naturally occurring communities of nitrifiers are generally flushed through the treatment system. The AquaMats® Process provides vast amounts of surface area in the 1-10 micron pore size range which bacteria require. As a result, high-rate nitrification is consistently achieved in a very wide range of temperature (including below ice cover) and load conditions. |
