  • A dimensionless approach for the determination of BOD first–order model coefficients

    A new method based on a dimensionless analysis of the BOD first order model is used to determine the model coefficients (k and L). Curves for the theoretical first order model for the first five days of BOD divided by the theoretical BOD5 for different k values are drawn. The experimental BOD1 through BOD5 are made dimensionless by dividing them with the experimental BOD5. These values are ...

  • What are the differences between Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)?

    Ask the expert: What are the differences between Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)? Answer: Both COD and BOD test methods aim to give an indication of the amount of pollution in a water sample. COD is the amount of oxygen required to chemically breakdown the pollutants whereas BOD is the amount ...

  • Teflon Coating

    The facility coats fiberglass cloth material with PTFE (generic Teflon) and generates approximately 3,500 gallons per week of wastewater. The wastewater has Teflon particles, surfactants, TiO2, yielding total solids up to 40,000 ppm. The majority of the solids are organic in nature. Previous testing done by US Filter followed the generic treatment approach using conventional coagulants (ferric, ...

  • Abattoir, commissioning of activated sludge plant case study

    This abattoir’s ancient activated sludge system needed complete refurbishment requiring the aeration tank to be drained. A characteristic of the waste water is its consistently very high ammonia concentration. The activated sludge system has to achieve a final effluent of 20 mg/l BOD, 10 mg/l ammonia and 30 mg/l suspended solids. The authorities required that this standard be ...

  • Assessment of classical surface organic loading design equations based on the actual performance of primary and secondary facultative ponds

    This article presents results from a performance evaluation of 73 full-scale primary facultative ponds and 37 secondary facultative ponds in Brazil. The data were used to test the applicability of some classical design equations for recommended surface BOD loading rates. The empirical equations proposed by Mara in 1976 and 1987 and the equation developed by McGarry and Pescod in 1970 were ...

    Sewer Misconnection Survey Date: March 2010 Location: Edgebaston Birmingham UK Purpose: To test the application of the SMF4 portable fluorimeter in the detection and quantification of organic pollution from faecal matter in Surface water Sewers. Background STS was invited independently by the Environment Agency and Severn ...

  • In-Situ® RDO® Methods for Analysis of BOD, CBOD, and DO

    Background — Dissolved Oxygen Measurement Since the publication of the Winkler method for measuring dissolved oxygen (DO) (Winkler 1888), the analysis of DO levels for water has been key to determining surface water purity and ecological wellness. The Winkler method is still one of only two analytical techniques used to calibrate oxygen electrode meters, the other procedure ...

  • Error analysis for river water quality prediction using back propagation modelling

    The purpose of this research is to describe the errors of Back Propagation (BP) technique that could be applied in river water quality prediction. ANN was trained by using the upriver data to forecast the downriver quality in two approaches of long-distance forecasting and short-distance forecasting respectively. It showed that the predicted results from short-distance approach were more accurate ...

  • Characterisation of Urban Runoff Pollution in Paris

    Abstract:Runoff was collected from 4 roofs, 3 courtyards and 6 streets on an experimental catchment in central Paris, and analysed for SS, VSS, COD, BODS, hydrocarbons, heavy metals both as regards dissolved and particles fractions. Whereas street runoff showed important SS, COD and hydrocarbon loads, roof runoff was noticeable for its high concentration of heavy metals... ...

  • PeCOD correlates COD results in pulp and paper industry

    PeCOD Directly Correlates to Standard Method 5220 A chemical supply company in the pulp and paper industry in the UK has demonstrated the successful correlation between the PeCOD COD (Chemical Oxygen Demand) Analyzer and Standard Method 5220. The standard method uses dichromate, mercury, silver, and sulfuric acid. These reagents are toxic to humans and highly hazardous to the ...

  • Non-linear modeling using fuzzy principal component regression for Vidyaranyapuram sewage treatment plant, Mysore – India

    Fuzzy principal component regression (FPCR) is proposed to model the non-linear process of sewage treatment plant (STP) data matrix. The dimension reduction of voluminous data was done by principal component analysis (PCA). The PCA score values were partitioned by fuzzy-c-means (FCM) clustering, and a Takagi–Sugeno–Kang (TSK) fuzzy model was built based on the FCM functions. The ...

  • Oxidative destruction of foaming agent, COD and TOC in wastewater using advanced oxidation technologies

    In recent years, improvement in ozone based advanced oxidation process design and efficiency resulted in lower capital and operating costs. An investigation into alternatives for hard COD, TOC and foaming agent oxidative destruction which is economically attractive and do not generate sludge, lead to the evaluation of our ozone based advanced oxidation processes (AOP). The results of this pilot ...

  • Characteristics of greywater from different sources within households in a community in Durban, South Africa

    The reuse of greywater is steadily gaining importance in South Africa. Greywater contains pollutants that could have adverse effects on the environment and public health if the water is not treated before reuse. Successful implementation of any greywater treatment process depends largely on its characteristics in terms of the pollutant strength. This study investigated the physico-chemical ...

  • Sewer Misconnection Survey - Birmingham UK - Case Study

    Background STS was invited independently by the Environment Agency and Severn Trent water to carry out a series of monitoring operations in an area which had a history of issues arising from the misconnection of waste water into a “clean” surface water sewer system. Traditionally surveys of this type are carried out using contractors who are tasked to lift ...

  • The application of surface engineered silica for the treatment of sugar containing wastewater

    The removal of sucrose and fructose from water at various high concentrations by surface engineered silica (SES) was studied using dissolved sugar in pure water. The results indicate that sugar at concentrations of up to 800 g/L can be removed by SES at a relatively high dose of 250 to 300 g/L. Based on these results, process water from a soft drink filling station which was contaminated by ...
