  • Sanitary Gate Valve Main Structural Features and Functions

    Sanitary gate valve's main duty is to cut off. When it is fully open the entire pipe gets straight through. At this time the pressure loss of medium operation reaches minimum. Its main advantage is the small fluid flow resistance. It is usually not required to frequently open and close or to keep the gate fully open or fully closed. It is not suitable for regulation, ...

  • How Does a Water Flow Meter Work?

    A water flow meter works by measuring the amount of water that passes though the flow meter. The most common mechanical types work by measuring the speed of flowing water that causes a turbine or piston to rotate. The volumetric flow rate of the water is proportional to the rotational speed. Other water flow meters include ultrasonic, magnetic and vortex flow meters. The best type of water flow ...

  • How Does a Thermal Flowmeter Work?

    A thermal flowmeter works by measuring the total mass flow rate of a fluid flowing through a pipe or duct. In a thermal flowmeter’s simplest working configuration, fluid flows past a heated thermal sensor and a temperature sensor. As the molecules of the fluid flow past the heated thermal sensor, heat is lost to the flowing fluid. The thermal sensor cools down while the temperature sensor ...

  • Low energy consumption vortex wave flow membrane bioreactor

    In order to reduce the energy consumption and membrane fouling of the conventional membrane bioreactor (MBR), a kind of low energy consumption vortex wave flow MBR was exploited based on the combination of biofilm process and membrane filtration process, as well as the vortex wave flow technique. The experimental results showed that the vortex wave flow state in the membrane module could be ...

  • Making Ultrasonic Liquid Flow Meter Installation Easier

    Ultrasonic transit-time flow meter technology is becoming one of the most adopted technologies for accurate liquid and energy/BTU measurement. Although a major benefit of the technology is that it is non-invasive and can be clamped to the outside of the pipe, an inherent challenge with ultrasonic clamp on liquid flow meters is finding the best location to measure the liquid. This means ...

  • Investigations of wall effect on permeability through porous media at low flow rates

    The study of percolation of fluids through permeable subsoil strata has always been a subject of great significance from engineering point of view. The permeability depends upon both material properties and fluid characteristics. Previous studies are concentrated on the influence of regularly shaped particles on permeability, whereas the present study aims to analyse its variation due to ...

  • Modeling effect of cover condition and soil type on rotavirus transport in surface flow

    Runoff from animal production facilities contains various microbial pathogens which pose a health hazard to both humans and animals. Rotavirus is a frequently detected pathogen in agricultural runoff and the leading cause of death among children around the world. Diarrheal infection caused by rotavirus causes more than two million hospitalizations and death of more than 500,000 children every ...

  • Numerical modelling of air-water flows in sewer drops

    The presence of dissolved oxygen (DO) in water flows is an important factor to ensure the aerobic conditions recognised as beneficial to preventing the occurrence of detrimental effects. The incorporation of DO in wastewater flowing in sewer systems is a process widely investigated in order to quantify the effect of continuous reaeration through the air-liquid interface or air entrained due to ...

  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • Sulfide emissions in sewer networks: focus on liquid to gas mass transfer coefficient

    H2S emission dynamics in sewers are conditioned by the mass transfer coefficient at the interface. This work aims at measuring the variation of the mass transfer coefficient with the hydraulic characteristics, with the objective of estimating H2S emission in gravity pipes, and collecting data to establish models independent of the system geometry. The ratio between the H2S and ...
