  • Mixed Liquor Suspended Solids (MLSS) Monitoring

    Mixed Liquor Suspended Solids (MLSS) Monitoring

    Activated Sludge Process Overview: The process deals with the treatment of sewage (and industrial wastewater) and was developed around 1912-1914. Activated sludge is a biochemical process for treating sewage and industrial wastewater that uses air (or oxygen) and microorganisms to biologically oxidize organic pollutants, producing a waste sludge (or floc) containing the oxidized material. Atmospheric air or pure oxygen is bubbled through primary...

  • Final Effluent Monitoring - Monitoring Turbidity and Suspended Solids in Effluent Discharges

    Final Effluent Monitoring - Monitoring Turbidity and Suspended Solids in Effluent Discharges

    Monitoring Final Effluent Suspended Solids or Turbidity is a key parameter for assessing the quality of the effluent in respect of meeting discharge consent and permitting levels. It is also an excellent indicator of the basic performance of the treatment works. An increase in the level of Turbidity is an indicator to plant operators that sludge blanket breakthrough is occurring, either through a failure in the treatment process or excessive flow...

  • Sludge Blanket Monitoring - Continuous Monitoring on Settlement Tanks and Clarifiers

    Sludge Blanket Monitoring - Continuous Monitoring on Settlement Tanks and Clarifiers

    Continuous monitoring of the sludge/water interface or sludge blanket is central to the efficient operation of clarifiers, thickeners and settlement tanks. Reliable measurement enables a control system to maintain the optimum depth of sludge in the tank. A sludge interface that is too high can result in pollution incidents caused by carry-over from a final settlement tank into the final effluent channel. The sludge can also become too thick to extract...

  • Dissolved Oxygen Monitoring - Monitoring Dissolved Oxygen in the Activated Sludge Process

    Dissolved Oxygen Monitoring - Monitoring Dissolved Oxygen in the Activated Sludge Process

    Being able to act on accurate measurement of Dissolved Oxygen in activated sludge plants will enable you to maintain levels of bacterial activity, avoid breaches in discharge consents and operate as cost effectively as possible. Too little dissolved oxygen can lead to bacterial inactivity and ineffective treatment, whilst too much, wastes energy and can cause unnecessary wear and tear to the aeration system.

  • pH Monitoring

    pH Monitoring

    What is pH? pH is a measure of acidity or alkalinity. The concentration of hydrogen ions (H+) causes a liquid to be either acidic (high concentration of hydrogen ions) or alkaline (low concentration of hydrogen ions). The pH range is from 0-14. Values below 0 or above 14 are possible but rare and cannot be measured with our electrodes.

  • Redox Monitoring

    Redox Monitoring

    What is Redox? The terms oxidation and reduction refers to the gain or loss of oxygen or hydrogen or electrons. There is always a transfer of electrons in reactions involving oxidation and reduction, that is, the oxidation state of one or more of the elements is always changed. The term Redox or Oxidation-Reduction Potential (ORP) describes a chemical reaction involving oxidation and reduction, the two processes always occur together because an...

  • Phosphate Monitoring - Orthophosphate and Total Phosphorus in the Wastewater Treatment Process

    Phosphate Monitoring - Orthophosphate and Total Phosphorus in the Wastewater Treatment Process

    The analysis of Phosphorus or Phosphate is a critical measurement in the monitoring and control of wastewater and industrial effluent treatment. By taking care to select the most appropriate analysis technique, taking a representative sample and preparing it correctly this measurement is readily achieved. Once a reliable, repeatable measurement is made the correct control technique can be applied. Control of Phosphate removal plants is covered in more...
