  • Introduction to water / effluent treatment
    Both municipal wastewater and industrial effluent are subject to strict UK and EU legislation regarding their disposal. Companies are required to meet criteria set out in discharge permits. Biodegradable organics, suspended...
  • Introduction to industrial oil / water separators
    Industrial oil / water separators are used for handling effluent from oil refining, chemical processing, metal finishing, food processing and rendering applications. Specific technologies include corrugated and tilted plate...
  • 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 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 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 ultraviolet (UV) treatment
    Ultraviolet treatment is a method of sterilisation that is used to kill pathogens, such as bacteria, viruses and fungi, found in potable water, wastewater, effluent and process water, without the use of chemicals. UV...
  • Introduction to actuators
    Actuators provide modulating, on/off or positioning control and automation of valves. They are used in industrial processes, water and effluent treatment, and heating, ventilation and air conditioning systems. They are...
  • 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 industrial valves
    Industrial valves are used to control, direct or regulate the flow of certain types of media: liquids, gases, steam, air, slurries and granular solids. They work by opening, closing or partially obstructing the passages...
  • 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 compressors
    Compressors move gases, including air, processes gases and waste gases, using a large increase in pressure. Blowers , by contrast, move gases using a moderate increase in pressure. Compressors are used in all industries.
  • 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 trace heating
    Electric trace heating , also known as surface heating, was initially developed in the 1930s when mineral insulated cables were used to produce heat. Since then, the technology has been continuously extended, with control...
  • 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...
