Application of LEDs in Wastewater Treatment Plants

Wastewater treatment plants are prone to explosive risks due to the presence of volatile, flammable compounds inside the building. The Occupational Safety and Health Administration (OSHA) has highlighted the dangers of such hazardous environments through a federal safety investigation of a Canastota wastewater plant. In 2014, a worker died from third-degree burns after a devastating ...

Radionuclides in wastewater treatment plants: monitoring of Sicilian plants

Three Sicilian wastewater treatment plants were monitored to assess the occurrence and the behaviour of radionuclides. Two sampling campaigns (screening and long-term) were carried out during which liquid and solid samples have been analysed. It was found that 131I mostly occurred in the samples analysed during the screening campaign (43% of the analysed samples contained 131I). ...

Sewage treatment plant

BONO ARTES has developed an activated sludge process called BIOCLAR, which is a great technological step forwards compared to conventional methods. A large part of civil and industrial installations, especially in developing countries, is located in remote and secluded areas where there is no possibility for connection to a public sewer. On the other hand, the minimisation of the impact on the ...

Perspectives on modelling micropollutants in wastewater treatment plants

Models for predicting the fate of micropollutants (MPs) in wastewater treatment plants (WWTPs) have been developed to provide engineers and decision-makers with tools that they can use to improve their understanding of, and evaluate how to optimize, the removal of MPs and determine their impact on the receiving waters. This paper provides an overview of such models, and discusses the impact of ...

Greenhouse Gas Inventories and Wastewater Treatment Plants

ABSTRACT A greenhouse gas inventory identifies the sources and quantities of GHG emissions from a facility or a larger organization. Several best practice standards exist that provide guidance for conducting GHG inventories for industrial facilities like a WWTP. Key considerations in a WWTP GHG inventory will include emissions associated with thefacility’s energy use as well as methane ...

Carbon footprints of Scandinavian wastewater treatment plants

This study estimates the carbon footprints of 16 municipal wastewater treatment plants (WWTPs), all situated in Scandinavian countries, by using a simple model. The carbon footprint calculations were based on operational data, literature emission factors (efs) and measurements of greenhouse gas emissions at some of the studied WWTPs. No carbon neutral WWTPs were found. The carbon footprints ...

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 ...
