Design characteristics for byproduct fatty acid recovery
This investigation was undertaken in order to determine the characteristics of crude fatty acids, recovered from the resin soap wastes of kraft pulp manufacture, so that efficient distillation units may be designed for distillation of the crude fatty acids. It was found that the crude fatty acids …

Management of disinfection byproduct production in small drinking water systems
… AT AUTHOR'S REQUEST.] Two groups of disinfection byproducts (DBPs) currently regulated in drinking water are trihalomethanes (THMs) and haloacetic acids (HAAs). The objective of this research was to better understand how the water treatment processes employed at four smaller municipal water …

Wildfire Impacts on Water Quality and Implications for Disinfection Byproduct Formation
… concentrations of the regulated disinfection byproducts (DBPs) known as trihalomethanes (THMs) and haloacetic acids (HAAs), though questions remain about changes in the reactivity of fire-affected DOM to form these. Less attention has been paid to unregulated nitrogenous DBPs (N-DBPs), such as …

The Recovery of Protein from Egg Yolk Protein Extraction Granule Byproduct
<p>In addition to proving an excellent source of nutrients, eggs are used in the food, cosmetic, and biotechnology industries for their rheological and bioactive properties. Much of the potential for the added value is in individual components of the egg, rather than the whole egg. At low speed …

Assessing byproduct mining and metal recycling as indicators of material criticality
… 1) the status of a metal being produced as a byproduct; 2) The market impact of increased metal recycling. To identify the type of major risks associated with a byproduct metal, a techno-economic analysis is performed on 42 carrier-byproduct metal pairs, by employing cluster analysis and …

Reduction of Disinfection Byproduct-associated Toxicity by Adjustment of Distribution System pH
Nitrogenous disinfection byproducts (N-DBPs) such as Haloacetonitriles (HANs) and haloacetamides (HAMs) have come under scrutiny in recent years due to their high toxicity compared to currently regulated carbonaceous disinfection byproducts (C-DBPs). Lowering concentrations of N-DBPs in drinking …

Cytotoxicity and Mutagenicity of Disinfection Byproduct Mixtures Formulated Using Free Chlorine and Monochloramine
… endpoints of drinking water disinfection byproducts (DBPs), but an emphasis on single compounds prevails. In this research, DBP mixtures were assessed using a cytotoxicity test with Chinese Hamster Ovary (CHO) cells and an Ames fluctuation test with Salmonella typhimurium TA-98 and TA-100 …

Evaluation of an Industrial Byproduct Glycol Mixture as a Carbon Source for Denitrification
In order to meet increasingly stringent total nitrogen limits, supplemental carbon must be added to improve the performance of the biological nutrient removal process. An industrial by-product that contained ethylene glycol and propylene glycol was used as a substitute carbon source for methanol in …

Synergy of Alum and Chlorine Dioxide for Curbing Disinfection Byproduct Formation Potential at Central Arkansas Water
… Maumelle and Lake Winona. To curb disinfection byproduct (DBP) formation, CAW has begun retrofitting their two plants to use chlorine dioxide as an alternative primary disinfectant followed by free chlorine secondary disinfection in the distribution system. In this study, fluorescence parallel …

The relationship between glucose metabolism byproduct, D-lactate, and vascular endothelial cell dysfunction and possible role in diabetes
Diabetes mellitus is a chronic disease associated with vascular complications. Vascular endothelial dysfunction caused by increased endothelial cell apoptosis contributes to diabetic cardiovascular complications. The glucose metabolic by-product, D-lactate, is elevated in diabetics and it is …

In planta studies of the corn pathogen Pantoea stewartii subsp. stewartii and applications of a corn-based industrial byproduct
… an additional research area was on repurposing a byproduct of corn ethanol production, syrup. It was hypothesized that this corn-based syrup could be utilized as a carbon source to grown bacteria. In turn, the resulting bacterial biomass could then be added as a fish feed supplement in …

Development and Evaluation of Photocatalytic Linear Engineered Titanium Dioxide Nanomaterials for the Removal of Disinfection Byproduct Precursors from Drinking Water
… in terms of their ability to remove disinfection byproduct (DBP) precursors from two natural surface water matrices via adsorption and photocatalysis. DBPs, which form when naturally occurring organic precursor compounds interact with chemical disinfectants used in drinking water treatment, are …

Characterization of residuals from novel anaerobic digestion of organic municipal solid waste for application as liquid fertilizer
… energy (in the form of methane) and a residual byproduct that can be used as fertilizer. Bottling and transportation of methane, however, presents numerous challenges. A novel anaerobic process is in development which would circumvent many of these challenges by instead producing a liquid …

The Economic Impact in Stanislaus and San Joaquin Counties if a Fruit and Vegetable Processor Left as a Result of Changes in the Food Processing Byproduce Use Program
… took a proactive approach to food processing byproduct waste and established the Food Processing Byproduct Use Program. It allows processors to transport byproduct to local producers, where it serves as an alternative input. There is concern that the program negatively impacts local …

Mixotrophic Production of Omega-3 Fatty Acid-rich Alga Phaeodactylum tricornutum on Biodiesel-derived Crude Glycerol
Crude glycerol is the major byproduct of the biodiesel industry. There is an abundance of this byproduct and purifying it for use in industries such as food, pharmaceutical, or cosmetic is prohibitively expensive. Developing an alternative use for crude glycerol is needed. Utilizing it as a carbon …
