  • How & When We Measure Turbidity

    Turbidity, along with Suspended Solids, is a way of measuring the clarity of a body of water, and how many particles are affecting it. The difference is that while Suspended Solids describes the density of the materials in the water, Turbidity describes how those materials affect light passing ...

  • Real-time control of sewer systems using turbidity measurements

    Real-time control (RTC) of urban drainage systems has been proven useful as a means to reduce pollution by combined sewer overflow discharges. So far, RTC has been investigated mainly with a sole focus on water quantity aspects. However, as measurement techniques for pollution of wastewater are advancing, pollution-based RTC might be of increasing interest. For example, turbidity data sets from ...

  • Wastewater engineers go with the flow

    The efficiency of maintenance work has been improved by water treatment engineers employing Intellisonde monitors in their final effluent. Designed primarily to measure water quality, the Intellisondes also measure flow, and this reading is being used to detect the accumulation of debris that necessitates a maintenance visit. Wastewater treatment efficiency is often measured by the analysis of ...

  • How & Why We Measure Suspended Solids

    In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids ...

  • Final effluent monitors protect wastewater treatment efficiency

    Southern Water operates 370 wastewater treatment plants (WWTP), many of which are unmanned for most of the time and most have numeric environmental permits, so a network of online monitors has been established to improve treatment and protect discharge compliance. This has involved the installation of final effluent monitors at over 300 sites in a programme that has lasted for more than ten ...


  • Emulsion-Breaking Techniques for Accurate Oil in Water Measurements

    A White Paper discusses emulsion-breaking techniques for ensuring accurate oil in water measurements. Certain water samples, such as those containing detergent, may form an emulsion when oil in water extraction into a solvent is done. In order to ensure an accurate measurement, the emulsion must be broken. Six techniques are described that can be used for reducing an emulsion ...

  • Continuous flow electrocoagulation in the treatment of wastewater from dairy industries

    Dairy industry wastewater contains high levels of organic matter, consisting mainly of fat, protein and products of their partial microbial decomposition. In the present study, the use of continuous electrocoagulation is proposed for the primary treatment of dairy wastewater. The electrochemical treatment was carried out in a continuous flow cell with aluminum electrodes. The influence of the ...

  • Efficiency of Process Measurement Technology for Determining Nutrient Parameters – Yesterday, Today and Tomorrow

    Abstract The costs and benefits of process measurement instruments in sewage treatment plants were the subject of intensive debate in the 1990s. Cost-benefit studies, comparing the potential savings in energy, consumables and personnel with the additional costs of using the instruments, resulted in recommendations specifying the minimum sewage treatment plant size at which the use of such ...


  • AquaLab Analyzer provides real-time phosphorus measurement in Everglades

    When it comes to ecosystem sustainability, Florida is no backwater. The South Florida Water Management District, which includes the unique Everglades habitat, had a major challenge. The EPA and various governmental authorities have defined limits for many water quality parameters to support a water body’s designated use. Any physical, chemical or biological condition that threatens the designated ...

  • Pilot Plant Investigation of Ozone Disinfection of Physicochemically Treated Municipal Wastewater

    Wastewater Treatment Plant (MUCWTP) to assess the feasibility of employing a full scale ozone disinfection system.Wastewater characteristics such as turbidity, COD, TOC, BOD, pH, ORP and suspended solids were monitored to assess their effect on ozone disinfection.  Fecal conforms (FC) were used as indicators to measure disinfection performance. Ozone disinfection was capable of reducing the ...

  • Rt-Ribosyn – A New Method to Measure the Specific Growth Rates of Distinct Microbial Populations in Engineered Systems

    ABSTRACTA molecular biology based method called RT-RiboSyn has been developed to measure the specific growth rate of microbial populations. This method analyzes culture samples that have been exposed to chloramphenicol for defined times. Chloramphenicol disrupts ribosome synthesis, which causes a buildup of the level of precursor 16S rRNA within the cells. Specific microbial populations can be ...

  • Enhanced membrane bioreactor process without chemical cleaning

    In membrane bioreactors (MBR) for wastewater treatment, the separation of activated sludge and treated water takes place by membrane filtration. Due to the small footprint and superior effluent quality, the number of membrane bioreactors used in wastewater treatment is rapidly increasing. A major challenge in this process is the fouling of the membranes which results in permeability decrease and ...

  • Dynamics of pollutant discharge in combined sewer systems during rain events: chance or determinism?

    A large database of continuous flow and turbidity measurements cumulating data on hundreds of rain events and dry weather days from two sites in Paris (called Quais and Clichy) and one in Lyon (called Ecully) is presented. This database is used to characterize and compare the behaviour of the three sites at the inter-events scale. The analysis is probed through three various variables: total ...

  • On-Line Nitrate/Nitrite Probes for BNR Process Control

    ABSTRACTReal time nitrogen monitoring plays an increasingly important role for the successful biological nutrient removal at wastewater treatment plants. Though traditionally dissolved oxygen has been the main process control parameter a greater understanding of the biological mechanisms and process conditions like nitrite/nitrate concentrations to achieve lower effluent values becomes necessary, ...

  • A review of the factors affecting sunlight inactivation of micro-organisms in waste stabilisation ponds: preliminary results for enterococci

    Waste stabilisation ponds (WSP) are efficient, cost-effective methods of treating wastewater in rural and remote communities in Australia. It is recognised that sunlight plays a significant role in their disinfection, however, due to the poor penetration of light in turbid waters it has been hypothesised that other mechanisms may also contribute to disinfection in WSPs. To date, studies have ...
