  • Pulp & Paper: Real-Time BOD & COD Monitoring

    A pulp and paper facility in Ontario, Canada has implemented an effective solution for monitoring chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in real-time. To address their need for more frequent data collection, the mill installed a real-time BOD/COD sensor from Real Tech. With real time monitoring, the facility saw an opportunity to optimize nutrient dosing in the ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Adaptive neuro-fuzzy inference system for real-time monitoring of integrated-constructed wetlands

    Monitoring large-scale treatment wetlands is costly and time-consuming, but required by regulators. Some analytical results are available only after 5 days or even longer. Thus, adaptive neuro-fuzzy inference system (ANFIS) models were developed to predict the effluent concentrations of 5-day biochemical oxygen demand (BOD5) and NH4-N from a full-scale integrated constructed wetland ...

  • Results of trials to remove BOD/COD from effluent arising from cellulosic fibre production case study

    A man-made natural fibre producer had produced a new high strength, fibrillated cellulosic fibre derived from wood pulp destined for use in garment manufacture. As a result of the IPC authorisation attached to the production of this product it became necessary to establish the biodegradability of various effluent streams leaving the production plant. In order to evaluate the feasibility of ...

  • Monitoring outfalls to Bathing Waters - Case study

    Bathing Water Catchment monitoring Date:2010 Location: Bude Cornwall UK Purpose: To carry out a river survey identifying potential pollution sources and their likely impact on bathing waters downstream. Background STS and the Environment Agency have, for some time, been discussing the issue of monitoring water courses which discharge directly into bathing waters. Of ...

  • Using UV Fluorescent Technology to monitor for organic pollutants

    For many years the water industry has relied on traditional sampling techniques to monitor water quality in a wide range of environments. Traditional tests such as BOD, PH, Dissolved Oxygen and Ammonia have formed the bedrock of monitoring parameters. There are however other ways to establish water quality and UV fluorescence offers an up to date solution for the investigation of ...

  • 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 ...

  • Waste Water Batch Treatment System

    Industrial Wastewater Treatment Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time. In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage ...

  • Phytoremediation technology for wastewater treatment: high rate transpiration system

    High Rate Transpiration System (HRTS) is a well-designed land treatment system composed of ridges and furrows and well-controlled hydraulic loading of wastewater. The present case study describes long-term operating experience of zero discharge of pulp and paper mill wastewater, which is characterised by high BOD, COD, TDS and colour that poses disposal problems into water bodies and on land. The ...

  • Performance of hybrid subsurface constructed wetland system for piggery wastewater treatment

    The objective of this study was to evaluate performance of a hybrid constructed wetland (CW) built for high organic content piggery wastewater treatment in a cold region. The system consists of four vertical and one horizontal flow subsurface CWs. The wetland was built in 2009 and water quality was monitored from the outset. Average purification efficiency of this system was 95 ± 5, 91 ± 7, 89 ...
