  • Wastewater Treatment Plant Town of Guilderland, NY

    The Town of Guilderland has been dependably served by a 1.5 meter BDP belt press since its installation in 1983. In 2004, the Town decided that an upgrade was necessary, and chose BDP due to their service and equipment reliability. The Town of Guilderland installed a 2.0 meter 3DPTM, and immediately experienced dryer cakes with higher throughput resulting in lower disposal costs. The 3DPTM was ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Analysis of chemical reaction kinetics of depredating organic pollutants from secondary effluent of wastewater treatment plant in constructed wetlands

    Four subsurface constructed wetlands were built to treat the secondary effluent of a wastewater treatment plant in Tangshan, China. The chemical pollutant indexes of chemical oxygen demand (COD) were analyzed to evaluate the removal efficiency of organic pollutants from the secondary effluent of the wastewater treatment plant. In all cases, the subsurface constructed wetlands were efficient in ...

  • Winery and distillery wastewater treatment by constructed wetland with shorter retention time

    The rationale for using constructed wetlands for treating wastewater is that wetlands are naturally among the most biological active ecosystem on earth. The aim of the study was to determine the impact of shorter retention time on the performance of constructed wetland in terms of Chemical Oxygen Demand (COD) and other elements removal. The application of wastewater with retention time of seven ...
