Comparative study on electrochemical 4-chlorophenol degradation in different diaphragm systems with combined reduction and oxidation properties
Two diaphragm electrolysis systems, two-electrode (anode–cathode) and three-electrode (cathode–anode–cathode), were compared for the electrochemical degradation of 4-chlorophenol. The performance of these systems was improved by feeding with hydrogen gas and then with air, in aid of the combined processes of reduction and oxidation. The 4-chlorophenol degradation, ...

The removal of the trivalent chromium from the leather tannery wastewater: the optimisation of the electro-coagulation process parameters
The capacity of the electro-coagulation (EC) process for the treatment of the wastewater containing Cr3+, resulting from a leather tannery industry placed in Medellin (Colombia), was evaluated. In order to assess the effect of some parameters, such as: the electrode type (Al and/or Fe), the distance between electrodes, the current density, the stirring velocity, and the initial Cr3+ concentration ...

A performance evaluation of three membrane bioreactor systems: aerobic, anaerobic, and attached-growth
Water sustainability is essential for meeting human needs for drinking water and sanitation in both developing and developed countries. Reuse, decentralization, and low energy consumption are key objectives to achieve sustainability in wastewater treatment. Consideration of these objectives has led to the development of new and tailored technologies in order to balance societal needs with the ...

Photocatalytic decolorisation and mineralisation of orange dyes on immobilised titanium dioxide nanoparticles
In this paper the photocatalytic decolorisation and mineralisation of three orange dyes (AO10, AO12 and AO8) in neutral, alkaline and hydrolysed solutions under UV light irradiation in the presence of TiO2 nanoparticles has been compared. The investigated photocatalyst was Millennium PC-500 TiO2 (crystallites mean size 5–10 nm) immobilised on non-woven paper. All the experiments were performed in ...

Total Organic Carbon (TOC) Analysis
What is Total Organic Carbon (TOC) Analysis? Total Organic Carbon (TOC) is the amount of carbon that is found in an organic compound. It has become an important indication of approximate levels of organic contamination and can therefore be used as a suggestion of water quality. In many cases, Total Organic Carbon analysis is used as an on-going monitor of change or lack of change in organic ...

Case Study: Ohio WTP Monitors Organics with UV254/UVT Analyzers
Water Treatment Plant Trusts and Relies on Real Tech UVT for Monitoring A surface water treatment plant (WTP) in Ohio has successfully used six Real Tech Real UV254 online analyzers in their WTP for over seven (7) years to help monitor and achieve the highest levels of organics removal and UV disinfection performance. Throughout the past 7 years the WTP has found Real Tech’s instruments to ...

Gas Monitoring Systems for your Unique Needs
When it comes to gas sensing solutions, there is no one-size-fits-all approach. Different industries have unique needs and requirements when it comes to the protection of personnel, property, and the environment. That’s why at Edinburgh Sensors, we strive to provide a comprehensive range of gas detectors for CO, CO2, CH4, and more, to ensure that all industries have the appropriate ...

Surface waters have varying levels of organics that originate from both natural and anthropogenic sources.
These organic compounds can cause challenges for the water treatment plant by increasing coagulant demand, causing taste and odor issues and increasing demand for disinfectants. Even when the organics themselves are not a health hazard, when combined with chlorine they may lead to the formation of harmful disinfection byproducts (DBPs). Reducing the concentration of organics via various treatment ...

The Role of Gas Sensing as a Drinking Water Purification Method
The processing of clean and safe drinking water and drinking water purification methods are an international issue. Estimates suggest that, if no further improvements are made to the availability of safe water sources, over 135 million people will die from potentially preventable diseases by 2020.1 Even within the UK, water purification and treatment is big business, with £2.1 billion ...

Measuring Ecosystem Metabolism After Stream Restoration
Measuring Ecosystem Metabolism After Stream Restoration Case Study Description Dams constructed of coarse woody debris (CWD) have long been used as a cost-effective approach for stream restoration efforts. Despite its relative prevalence, little is known about CWD’s long-term ecological impacts and efficiency in reducing erosion. In his doctoral dissertation Samuel Bickley, Ph.D., conducted ...
