  • Introduction to chemical dosing systems
    Chemical dosing systems typically comprise a chemical storage tank, pipework, controls and a frame or cabinet, as well as one or more metering pumps . They can dose liquids, powders or polymers. One common application is the...
  • Introduction to reverse osmosis
    Reverse osmosis plant produces high-purity water for potable supplies or low-conductivity process water for industrial systems. A type of membrane filtration water treatment or pre-treatment technology, RO is used for the...
  • Introduction to air / gas purification
    Indoor air quality (IAQ) can be compromised by micro-organisms, dust, fumes, smoke, gases, such as CO2, and volatile organic compounds (VOCs), as well as other airborne particles. Such polluted conditions may be immediately...
  • Introduction to gas measurement
    Gas measurement instrumentation covers a diverse range of applications. Personal monitors are used by people working in confined spaces where there is a risk of exposure to toxic gases, such as hydrogen sulphide or carbon...
  • Introduction to steel storage tanks
    Metal storage tanks are corrosion resistant, making them suitable for the containment of potable and non-potable water; sludge, slurry and sewage; hazardous chemicals; and industrial effluents. Materials include stainless...
  • Introduction to metering and dosing pumps
    Metering and dosing pumps are widely used in water treatment processes, as well as chemical processing, food and drink manufacturing, pharmaceuticals, pulp and paper production and laboratories. They are used for delivering...
  • Introduction to gas dosing systems
    Gas feed systems are used to treat water and wastewater in municipal and industrial processes. The safest systems tend to operate on all-vacuum principles. Chlorinators disperse chlorine into water and wastewater in a...
  • Introduction to industrial process pumps
    A broad range of industrial pumps is available to handle aggressive, corrosive, toxic, high temperature, high viscosity, fibrous and solids-laden substances. They are used in every industrial setting, from chemical...
  • Introduction to mixers
    Mixers are used to mix, blend, homogenise, agitate and aerate both liquids and solids in a range of sectors, from wastewater treatment through to food processing. Dynamic liquid mixers use propellers to provide local...
  • Introduction to air flotation
    Air flotation covers a set of technologies designed to remove suspended matter, including fine solids, fats, oils and greases, from municipal wastewater, industrial effluent, water and oil-water mixtures. Liquids will often...
  • Introduction to fragances and eradicating agents
    Airborne odour control systems are used to reduce, neutralise or eliminate unpleasant smells and air pollution from wastewater and water treatment works, landfill and composting sites, waste transfer stations, farms and...
  • Introduction to flow measurement
    The best flowmeter for a specific application will depend on: - what’s being measured (e.g. air or granular solids) - the nature of the fluid (e.g. viscosity, turbidity, aggressive chemicals) - where it’s being measured...
  • Introduction to centrifuges
    The centrifuge is a mechanical separation technology that uses accelerated rotation to separate out substances of different densities. These will be either a solid and a liquid or two immiscible liquids, such as water and...
  • Introduction to biological treatment
    Biological treatment systems are commonly used to treat municipal wastewater and sewage, as well as sludge and industrial effluents. Biological systems use bacteria, in either aerobic or anaerobic conditions, to break down...
  • Introduction to tank covers
    Industrial tank covers are used for large tanks in the petrochemical, industrial process, water, wastewater and sewage treatment industries. Tank covers limit the emission of hazardous gases and odours to protect the...
