  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

  • Why it is important to measure Dissolved Oxygen in aeration lanes

    Dissolved Oxygen is a key parameter in the efficient treatment of waste water during the secondary treatment stage; the point at which organic waste is oxidised to form carbon dioxide, water and nitrogen compounds. It is important to act on accurate measurements of Dissolved Oxygen in activated sludge plants for the following reasons: To ...

  • Theory to Practice: Oxygen Transfer and the New ASCE Standard

    ABSTRACTOxygen transfer is an important part of wastewater treatment and accounts for as much as 60% of the energy consumption for the activated sludge process. Prior to 1984, no standard method for quantifying oxygen transfer existed, which created problems in the design and warranties for treatment plants. The ASCE Standard for the Measurement of Oxygen Transfer in Clean Water and the ASCE ...

  • Probing the debromination of the flame retardant decabromodiphenyl ether in sediments of a boreal lake

    After decades of using polybrominated diphenyl ethers (PBDEs) as flame retardants, a large reservoir of these toxins has accumulated in ecosystems worldwide. This study used an innovative approach to examine whether the fully brominated PBDE, decabromodiphenyl ether (decaBDE), degrades to more toxic congeners in aquatic environments. We incubated intact sediment microcosms with high‐purity ...

  • Measuring Short-Term BOD

    Measurement of oxygen uptake rates in activated sludge processes is essential to their satisfactory operation. Traditionally, oxygen uptake rates (OUR) have been determined by using a dissolved oxygen probe to measure the change in dissolved oxygen in a BOD bottle. While this method is rapid, it provides only a snapshot, at a single point in time, of the oxygen uptake rate reaction in a treatment ...

  • Monitoring pH and ORP in a SHARON reactor

    This paper analyses the valuable information provided by the on-line measurements of pH and oxidation reduction potential (ORP) in a continuous single high ammonia removal over nitrite (SHARON) reactor. A laboratory-scale SHARON reactor equipped with pH, ORP, electric conductivity and dissolved oxygen (DO) probes has been operated for more than one year. Nitrogen removal over nitrite has been ...

  • Reliable silica monitoring supports power station efficiency

    West Burton B CCGT is a Combined Cycle Gas Turbine power station near Nottingham in the UK. It has three open-cycle gas turbines capable of generating enough electricity for approximately 1.5 million UK homes. In common with all combustion based power stations, the CCGT has a requirement to monitor silica levels in the Plant’s water and steam processes. Sean Todd, the Plant’s Control ...

  • Singapore gardens an environmental sustainability showcase - Case Study

    Opened in spring 2012, Gardens by the Bay features an aquatic ecosystem with sustainable water cycles Singapore government officials’ vision to become a “city in a garden” came to fruition by redeveloping Marina Bay and boldly allocating prime land and a hefty budget for that purpose. Years of construction later, the Gardens by the Bay officially opened in the spring of ...
