  • Relationship between turbidity and total suspended solids concentration within a combined sewer system

    This article confirms the existence of a strong linear relationship between turbidity and total suspended solids (TSS) concentration. However, the slope of this relation varies between dry and wet weather conditions, as well as between sites. The effect of this variability on estimating the instantaneous wet weather TSS concentration is assessed on the basis of the size of the calibration dataset ...

  • A Regulatory Perspective on Maintenance of Disinfection Systems

    ABSTRACTThe Clean Water Act contains requirements to set water quality standards for all contaminants, including bacterial contaminants, in surface waters. Wastewater treatment cannot be expected to remove all of the bacterial contaminants, and as a result, many organisms remain in the waste stream. Therefore, disinfection of treated wastewaters is designed to reduce bacterial numbers to a safe ...

  • From mess to mass: a methodology for calculating storm event pollutant loads with their uncertainties, from continuous raw data time series

    With the increasing implementation of continuous monitoring of both discharge and water quality in sewer systems, large data bases are now available. In order to manage large amounts of data and calculate various variables and indicators of interest it is necessary to apply automated methods for data processing. This paper deals with the processing of short time step turbidity time series to ...

  • 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 ...


  • 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 ...

  • 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 ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...
