  • Monitoring Nitrates in Drinking Water and Wastewater

    Nitrate is present in high levels in wastewater due in part to the high nitrates present in human sewage but also from some types of industrial effluent entering the municipal sewer system. Nitrate is also a very common contaminant in both surface water and ground water. Nitrate occurs naturally in source water as a result of decaying plants. However, there are other manmade sources of ...

  • Monitoring Hydrocarbons in Wastewater - Case Study

    The Situation A wastewater treatment company operated an oil/water separation facility on a multi-acre industrial site in Northern California. Its purpose was to recycle oil products for profit while at the same time providing a wastewater treatment service for industries based in Northern California. The oily water mixes processed by the company were obtained from ...

  • Wastewater Monitoring Equipment for An Airport Group

    CAS DataLoggers recently provided the wastewater monitoring solution for a major airport group based in the UK whose fluid run-off threatened to endanger the aquatic ecosystem near the airports. The commercial airline needed an online device capable of monitoring toxic discharges into local rivers. The airline routinely sprayed de-icer and anti-icer solution onto their aircraft before taking off ...

  • 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 ...

  • 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, ...

  • 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 Monitoring Series, Part 2: The Use of 2nd Generation ATP Monitoring Systems

    In October, we featured Part I of a three-part series on "Getting a Handle on Living Biomass in Wastewater Treatment." Here, we present Part II of the series which focuses on a revolutionary breakthrough technology that uses Adenosine Triphosphate (ATP) for the measurement of total microbiological content in a given sample. Through years of successful research, development, and field application, ...

  • 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 ...

  • Municipal Wastewater

    Municipal wastewater namely sewage is generated by residential, institutional, commercial and industrial establishments. It includes household waste liquid from toilets,baths,showers,kitchens, and sinks drained into sewers. In many areas, sewage also includes liquid waste from industry and commerce. The separation and draining of household waste into greywater and blackwater is becoming more ...

  • Treating wastewater as a resource

    A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. Background Leachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has ...

  • Monitoring and evaluation of removal of pathogens at municipal wastewater treatment plants

    The concentrations and removal of Cryptosporidium, Giardia, and microbial indicators, including somatic coliphages and fecal coliforms were investigated through the wastewater treatment processes at three municipal wastewater treatment plants in Beijing, China. The experimental results showed that the concentrations of Cryptosporidium in untreated wastewater, ...

  • Rapid Monitoring of Municipal Wastewater Primary Effluent - Case Study

    The primary effluent of a Municipal Wastewater Treatment Plant (MWWTP) is monitored to understand organic loading going to the next stage of treatment, the activated sludge process. This process removes organics via consumption by microorganisms living in the sludge. Knowing the composition of incoming primary effluent is important to prevent organic overloading and improve process optimization ...

  • Application note: The Sievers InnovOx TOC Analyzer: Wastewater Monitoring

    Overview Wastewater is used water. It can include substances such as human waste, food scraps, oils, soaps, and chemicals. Manufacturing industries as well as wastewater municipalities must comply with the United States Environmental Protection Agency’s (USEPA) Clean Water Act (CWA) regulations. In order to discharge treated wastewater and be compliant with the CWA, a ...

  • Monitoring and validation of decentralised water and wastewater systems for increased uptake

    Decentralised water and wastewater systems are being implemented to meet growing demand for municipal services either in combination with centralised systems or as standalone systems. In Australia, there has been increased investment in decentralised water and wastewater systems in response to the capacity constraints of existing centralised systems, an extended period of below average rainfall, ...

  • 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 ...

  • Gaussian process regression for monitoring and fault detection of wastewater treatment processes

    Monitoring and fault detection methods are increasingly important to achieve a robust and resource efficient operation of wastewater treatment plants (WWTPs). The purpose of this paper was to evaluate a promising machine learning method, Gaussian process regression (GPR), for WWTP monitoring applications. We evaluated GPR at two WWTP monitoring problems: estimate missing data in a flow rate ...

  • Times are changing: Wastewater as a resource

    Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

  • Real-time monitoring and forecasting of odor after dewatering in wastewater treatment

    A real-time odor monitoring system was developed to evaluate and predict odors levels of dewatered solids generated by the District of Columbia Water and Sewer Authority’s (DCWASA) advanced 370 mgd wastewater treatment plant (WWTP) in Washington, DC. Each year, DCWASA generates over 400,000 wet tons of biosolids and recycles these biosolids by applying them to over 20,000 acres of agricultural ...
