  • 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 ...


  • Radionuclides in wastewater treatment plants: monitoring of Sicilian plants

    Three Sicilian wastewater treatment plants were monitored to assess the occurrence and the behaviour of radionuclides. Two sampling campaigns (screening and long-term) were carried out during which liquid and solid samples have been analysed. It was found that 131I mostly occurred in the samples analysed during the screening campaign (43% of the analysed samples contained 131I). ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Improved Wastewater Treatment & Paper Mill Performance With New COD Monitoring Technology

    The Nordic Wood Biorefinery Conference was held in Stockholm, Sweden during March 28-30, 2017. An abstract presentation authored by partners from VTT, Kemira, FPInnovations and MANTECH was presented during the conference. The PeCOD® Analyzer has the ability to enable pulp and paper mills to improve effluent treatment process and to optimize chemical programs, leading to proper ...

  • Application Focus: Biological Wastewater Treatment

    In knowing the size and health of the active biomass population in a wastewater treatment process, cause-and-effect relationships can then be established with process variables. If a change in the process is beneficial or detrimental to the population, ATP results will indicate to what degree the population is helped or harmed by the change. Since ATP measurements isolate the living population, ...

  • Pollutant monitoring in sludge treatment wetlands

    Phragmites australis for sludge dewatering and stabilization processes have been widely proved. The presence of reeds, indeed, efficiently allows solids dewatering and organic matter stabilization in order to obtain a stabilised product that can be suitable for land application, even if its environmental impact has to be considered. The actual revision of the European Union's Working Document on ...

  • Development of monitoring and evaluation system for wastewater issues in Palestine

    Wastewater is the main source of groundwater pollution if it is not properly collected and treated. In many parts of the Gaza Strip and the West Bank wastewater is collected through cesspits, while in other areas it is collected through networks and treated in central treatments plants. Collecting aggregate information on the level of indicators with concern to the wastewater issues (collection, ...

  • Biological wastewater treatment followed by physicochemical treatment for the removal of fluorinated surfactants

    Perfluorinated surfactants (PFS) have become compounds of high concern during the last decade. While “conventional surfactants” are degraded to a great extent in the biological wastewater treatment process, partly or perfluorinated surfactants are not only stable against biodegradation but also against oxidizing agents, they even resist OH-radical attacks. Our objectives were to eliminate the ...

  • Excel Spreadsheets for Descriptive Statistics of Wastewater Treatment Plant Performance

    I would like to share with you simple Excel spreadsheets that we developed for doing descriptive statistics of wastewater treatment plant performance. They are very simple to use, and the user has only to fill in cells marked in yellow with information and monitoring data (copy from your own spreadsheet and paste as VALUES). The spreadsheets are entirely open (no macros or anything protected), ...

  • Improving Biological Wastewater Treatment Process Control through ATP-Based Parameters

    ABSTRACTBiological wastewater treatment processes harness the ability of microorganisms to break down and assimilate organic compounds that, if left untreated, cause detriment to the environment. Although this process occurs naturally, engineered systems are used to accelerate the process by optimizing bioreactor conditions to promote higher-than-typical biomass concentrations, thus increasing ...

  • Cellular ATP – A Superior Measure of Active Biomass for Biological Wastewater Treatment Processes

    Biological wastewater treatment processes harness the ability of microorganisms to break down and assimilate organic compounds that, if left untreated, cause detriment to the environment. Although this process occurs naturally, engineered systems are used to accelerate the process by optimizing bioreactor conditions to promote higher-than-typical biomass concentrations, thus increasing the rate ...

  • The assessment of the coke wastewater treatment efficacy in rotating biological contractor

    Coke wastewater is known to be relatively difficult for biological treatment. Nonetheless, biofilm-based systems seem to be promising tool for such treatment. That is why a rotating biological contactor (RBC) system focused on the Anammox process was used in this study. The experiment was divided into two parts with synthetic and then real wastewater. It was proven that it is possible to treat ...

  • Passive Wastewater Treatment System Introduced to Colorado - Case Study

    After a homeowner’s septic system failed on a small lot and the homeowner was faced with a large bill for a new system, Virgil Russon of Greeley, Colo., looked for a solution. He did extensive research for alternatives to pipe and stone, and found Advanced Enviro-Septic (AES). The AES System provides advanced treatment of septic effluent to tertiary quality, is completely passive with no ...

  • BM Respirometry applied to a novel control strategy of nitrification in a wastewater biological treatment

    Abstract In wastewater treatment plants, the biological nitrogen removal (BNR) has acquired critical importance, which makes that in the majority of the cases the overall process control largely depends on the control of this treatment. The normal aerobic process of nitrification is performed by specific aerobic living microorganisms and a lack of information on their bioactivity may ...

  • Wastewater Monitoring Series, Part 1: Identifying the Gaps in Conventional Biomass Test Methods in Wastewater

    Biological wastewater treatment systems require living biomass to remove biodegradable contaminants from wastewater.  Effective treatment is directly dependent on the concentration of healthy biomass. It stands to reason that having an easy method to directly measure the quantity and quality of living biomass would be tremendously beneficial to the operation of biological wastewater ...

  • Biological treatment of colored wastewater by Streptomyces fulvissimus CKS 7

    This study aims to investigate the biological processes related to the biodegradable potential of growing microbial cells for contaminated water treatment. Thus, the use of the Streptomyces fulvissimus CKS 7 (CKS7) has been evaluated for decolorizing efficiency of a solution containing a cationic triphenylmethane dye, crystal violet. The color reduction was monitored by UV–Vis spectroscopic ...
