  • ppb Dissolved oxygen measurement

    Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible for costly replacement of piping and equipment by corrosive attack on metah. what is Dissolved Oxygen? Dissolved axygan (D.O.f is the ...

  • 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 ...

  • Dissolved oxygen measurements in aquatic environments: The effects of changing temperature and pressure on three sensor technologies

    Dissolved oxygen (DO) is probably the most important parameter related to water quality and biological habitat in aquatic environments. In situ DO sensors are some of the most valuable tools used by scientists and engineers for the evaluation of water quality in aquatic ecosystems. Presently, we cannot accurately measure DO concentrations under variable temperature and pressure conditions. ...

  • Prediction of dissolved oxygen in reservoirs using adaptive network-based fuzzy inference system

    Predicting water quality is the key factor in the water quality management of reservoirs. Since a large number of factors affect the water quality, traditional data processing methods are no longer good enough for solving the problem. The dissolved oxygen (DO) level is a measure of the health of the aquatic system and its prediction is very important. DO dynamics are highly nonlinear and ...

  • Water quality measurement extreme

    Background The characteristics of the Rio Tinto in the south-west of Spain, near Sevilla, are his ruby colour and the extremely sour pH-value between 0 and 2 pH-units. The river carries a mixture between poisonous heavy metals like copper, nickel, arsenic, iron and cadmium, dissolved in high-percent sulphuric acid. It’s not proved where these unusual conditions come from. As per current ...

  • 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 ...

  • Ultrasonic depth sensor to measure water levels

    The Dutch algae control company LG Sonic introduced an ultrasonic depth sensor to give the customers real-time insight in the water levels which allows them to adequately deal with water level fluctuations. Reservoirs used for industrial processes or the production of drinking water often deal with strong water level fluctuations. Due to events of high demand and evaporation, water levels in ...

  • What are the main indicators of water quality?

    “Water is the driving force of all nature;” so said Leonardo da Vinci. The survival of our planet depends on the availability of water and the condition that it is in. It is therefore vital to make sure that it is able to provide a hospitable environment for those that live in it, and is free from harmful levels of substances for those that drink it. Not ...

  • Analysis of nitrogenous and algal oxygen demand in effluent from a system of aerated lagoons followed by polishing pond

    In this descriptive-analytical study, nitrogenous and algal oxygen demand were assessed for effluent from a system of facultative partially mixed lagoons followed by the polishing pond using 120 grab samples over 1 year. Filtered and non-filtered samples of polishing pond effluent were tested in the presence and absence of a nitrification inhibitor. Effective factors, including 5-day biochemical ...
