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 ...

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 ...

An investigation into the effectiveness of sand media amended with biochar to remove BOD<sub>5</sub>, suspended solids and coliforms using wetland mesocosms

An investigation into the effectiveness of sand media amended with biochar to remove BOD₅, suspended solids and coliforms using wetland mesocosms

Constructed wetland ecotechnologies (CWEs) are a promising solution to effectively treat domestic wastewater in developing countries at low cost. This paper reports the findings of the effectiveness of sand media amended with woody biochar and two plants species (Melaleuca quinquenervia and Cymbopogon citratus) in removing biological oxygen demand (BOD5), ...

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 ...

Biological Monitoring Tools for Recycling Hazardous Effluents

Abstract Increasing dependence on chemicals and rapid developments in chemical technology have practically triggered the growth of chemical industries in India. Globally, Basel convention guidelines are available for transboundary movement of hazardous wastes. However, at the national levels, health damage, resources losses and ecological impairment due to hazardous wastes indiscriminate ...

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 ...

Analysis of monitoring results of the separation and greywater treatment system at Chester Woods Park, Olmsted County, Minn.

Introduction In 1993, Olmsted County installed an advanced individual sewage treatment system (ISTS) at the caretaker's residence at a County-owned park to demonstrate waste load reduction and downsizing of drainfield area. The subject system has two components--1) a composting/vermiculture blackwater system and a 2) aerobic graywater treatment system. The separation of the high strength ...

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 ...

Treatment plant protected by effluent monitor at major drinks factory

The installation of a BioTector continuous TOC (Total Organic Carbon) monitor to police the front end of Cobevco’s wastewater treatment plant has enabled tight control of the treatment process. Delivering results 20 times faster than laboratory techniques, the monitor at the Elton facility in Cheshire provides advance notice of organic overload so that the plant is able to instantly divert ...

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 ...

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 ...
