  • Introduction to clarifiers
    Clarifiers are tanks that encourage solids to separate out of wastewater and industrial effluents. Light materials float to the surface and are removed by a skimmer, whilst heavier solids settle on the bottom of the tank. In...
  • Introduction to penstocks
    Penstocks are used for controlling the flow of large volumes of water in wastewater treatment, sewage, irrigation, hydraulic works and hydro-electric power applications. Penstocks are typically mounted in a wall, a channel...
  • Introduction to municipal / industrial screens
    Municipal and industrial screens are used as part of the processing and pre-treatment of a broad range of media. In wastewater, sewage and grey water screening, large objects, solids and coarse material have to be separated...
  • Introduction to filter media
    Filtration media is widely used in municipal water treatment, and wastewater and effluent treatment processes. Plastic filter media - typically manufactured from polypropylene or PVC - is suitable for the biological...
  • Introduction to tank and bund liner membranes
    Tank and bund liners are used in primary or secondary containment applications. In primary containment , the membrane is used to line the tank itself. It must be specified in a material that is suitable for the liquid...
  • Introduction to gas scrubbers
    Gas scrubbing systems remove particulates and gaseous contaminants, including hydrogen chloride, hydrogen sulphide, ammonia and sulphur dioxide, from industrial flue gases. With wet scrubbers the flue gases are brought into...
  • 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 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 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 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 aerators
    Aeration systems increase the supply of oxygen, as well as providing mixing, in the biological treatment processes commonly used to treat municipal wastewater and industrial effluents. They are typically installed in mixing...
  • Introduction to water / wastewater / effluent pumps
    Water, wastewater and effluent pumps are used in sewage treatment, municipal water treatment and heavy industrial applications to move liquids from one stage of a process to another. Wastewater and sewage pumps are designed...
  • 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 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 liquids measurement
    Measuring and monitoring the characteristics of liquids is a fundamental part of many industrial and environmental processes. Equipment ranges from handheld or portable instruments typically used by operators in the field to...
