Does the recycling of waste streams from drinking water treatment plants worsen the quality of finished water? A case assessment in China
The overall purpose was to assess the feasibilities of recycling filter backwash water (FBWW) and combined filter backwash water (CFBWW) in a drinking water treatment plant in south China. The variations of regular water-quality indexes, metal indexes (Al, Mn and Cd), polyacrylamide and disinfection by-product indexes (trihalomethanes and their formation potentials) along with the treatment ...

Optimize Chemical Dosage for Water Treatment with UV254
Drinking water plants that use surface water or groundwater under the influence of surface water are susceptible to high levels of organic matter in the raw water. Reduction of organic matter through coagulation/ sedimentation and filtration plays a critical role in lowering the potential for disinfection by-product formation (DBP) and minimizing operational problems. Organic matter in water ...

Photodegradation of 4-chloronitrobenzene in the presence of aqueous titania suspensions in different gas atmospheres
The photocatalytic degradation of 4-chloronitrobenzene (4-CNB) was carried out using Degussa P25 TiO2 as photocatalyst in three different gas atmospheres: nitrogen, oxygen, and ozone. The total organic carbon (TOC) and inorganic anions including chloride, nitrite, and nitrate anions were measured to monitor the mineralization processes, while the degradation of 4-CNB and the formation of ...

Chemiluminescence detection for nitrogen containing compounds compared to other approved techniques
Abstract Nitrogen monitoring is important for process control, regulations, and economic reasons. There are several techniques that can be used to monitor nitrogen, some of which can be time consuming, labor intensive, and may have waste disposal concerns. This study examines using a high temperature combustion (HTC) Total Organic Carbon (TOC)/Total Nitrogen (TN) Analyzer with chemiliumunescence ...

Degradation rate of anaerobically digested sewage sludge in soil
The objective of this study was to monitor the degradation and obtain the mineralization fraction of anaerobically digested sludge, also known as digestate, under field conditions, when applied to the surface or incorporated into the soil. Sludge was applied to a dystrophic Inceptisol at a dose of 500 kg ha–1 yr–1 of total nitrogen, where the monitoring period of the mineralization process ...

Organic Matter in Drinking Water: A Guide for Simple Online Monitoring
Control of dissolved organics has been one of the highest priority concerns for most water treatment plants for over 20 years. Organics monitoring is an even more critical issue today in the face of more stringent regulations and concerns around trace organics, emerging contaminants, and even counter-terrorism or water security. Despite the critical need, many plants still rely primarily on ...

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 ...

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 ...

Dairy Wastewater: Identify and Reduce Product Loss with Real-Time BOD/COD Monitoring
LOST PRODUCT = LOST REVENUE Manufacturers in the food and beverage industry lose significant quantities of product in the production process. In the dairy industry, milk losses are on average 2-3% of total production and can be even higher for ice creams and novelty products. While it seems like a relatively small percentage, these losses can equate to a large volume of product lost every year, ...
