Biofiltration WWTP 50.000 PE
The aerated upflow biological filtration (biofiltration) is a technology which is today successfully used in more than 500 European wastewater treatment plants. Among this, the one of Sallek Valley, in Slovenia, differs by a two stage biofiltration and a part-recirculation of sludge from thickener to increase the COD concentration needed for denitrification. This process allows an advanced denitrification- nitrification in a very compact way and low operation costs. The results of the wastewater treatment plant...
WWTP Covers Its Grit Tanks to Help Address Odor Concerns
The Customer: The Georgetown Wastewater Treatment Plant (WWTP) located in Ontario, Canada, provides industrial and municipal wastewater treatment for the urban area in the Town of Georgetown. The plant treats approximately 17.5 ML of wastewater per day. It is sized to accommodate the wastewater treatment needs of a local dairy processing facility, the plant’s largest industrial contributor of wastewater. The Customer’s Needs: Built in 1960, the Georgetown WWTP was originally located in a remote...
Town Branch WWTP Controls Odors with Modular Covers
The Customer: The Town Branch Wastewater Treatment Plant located in Lexington, Kentucky, USA, serves a population of 130,000—about 60 percent of Lexington-Fayette County. The plant began operating in 1919, and currently treats almost 11 billion gallons of wastewater annually. The Customer’s Needs: The Town Branch Wastewater Treatment Plant needed to replace failing steel-dome gas collecting covers. This meant converting four existing tanks, which included a blending tank, two secondary digesters,...
Biogas desulphurisation in the WWTP do Norte (Portugal) - Case Study
The Northern Wastewater Treatment Plant (WWTP) is one of the biggest in the central region of Portugal, servicing various municipalities. The infrastructure is located in the area of Coimbra, Leiria, taking up 6 hectares of land; it receives effluents from some 250,000 inhabitants across multiple municipalities. It has the capacity to treat around 38,000m3 of wastewater on a daily basis, 77% of which is domestic, 18% industrial and 5% corresponding with other types of effluents. The resulting biogas from this...
CHIP-tuning for biological wastewater treatment plants
The demand for efficiency improvement in municipal and industrial wastewater treatment plants (WWTP’s) is increasingly based on problems related to the water quality, process stability and/or insufficient performance in the COD removal and/or nitrification process. New, stricter requirements or the need for higher removal efficiency intensify the demand for optimizing the existing technology by means of “tuning“. This article is about the efficiency improvement of existing biological treatment...
