Performance Characterization of Coagulation Pretreatment for Two Industrial Effluents
… and flocculation were tested for two different industrial effluents. Coagulation-Flocculation and activated carbon adsorption were applied for the remediation of oil sands process-affected water (OSPW), generated from oil sands operations in Alberta, Canada. OSPW is a complex mixture of …

Removal of Perfluorooctane Sulfonate (PFOS) and Related Compounds From Industrial Effluents
… more than half a century in a wide variety of industrial and consumer products ranging from stain repellents such as Teflon® to aqueous fire-fighting foams and to grease-proof food packing. The public health and environmental risks posed by PFAS have driven environmental agencies and the …

The effects of temperature on the sensitivity of Daphnia pulex to two simulated industrial effluents
… assessed. Daphnia pre-exposed to both simulated effluents and short-term thermal shock had significantly more nonviable eggs and young. Survival of 20 C Daphnia pre-exposed to both simulated effluents and subjected to a 12 C thermal shock was significantly reduced. Reproductively immature Daphnia …

ANAEROBIC TREATMENT OF HIGH SALINE PHARMACEUTICAL WASTEWATER
… challenges for biological treatment of saline industrial effluents. In this study, various anaerobic technologies were attempted including anaerobic sequencing batch reactor (AnSBR), up-flow anaerobic sludge blanket (UASB) and anaerobic membrane bioreactor (AnMBR), and different types of …

The influence of cadmium on hepatic protein synthesis in the rat
… so their volatility, as in the case of Pb, is an industrial hazard. Cd has recently received prominence as a cause of environment pollution due to its accumulation in water supplies and crops from Zn mining operations and industrial effluents.

Shallow water outfalls for brine disposal from desalination plants
… closely spaced jets are often used to discharge industrial effluents in coastal waterbodies. Examples of such effluents include heated water from thermal power plants, treated wastewater effluent from sewage treatment plants, and reject brine from desalination plants. At locations with shallow …

The importance of bluegill feeding behavior within an automated biological monitoring system for industrial wastes
… system designed to detect sublethal levels of industrial effluents. Measurements of fish (Lepomis macrochirus, Rafinesque) activity, as well as respiration, were employed as indicators of toxicity. Prior to this study, fish used within the system were unfed throughout the duration of an …

The development and assessment of an automated biological monitoring system using crayfish locomotor activity to detect toxic stress
… of developing toxicity and hazardous spills in industrial effluents rapidly enough to prevent serious damage to receiving waters. A computer automated system was developed to continuously monitor spontaneous locomotor activity of eight crayfish. Electric potentials generated by muscular …

Responses to lead in the freshwater isopods Asellus Aquaticus and A. Meridianus
… encountered. The introduction of metals by industrial effluents and domestic sewage (Holdgate 1979) and aerial fallout (Peyton et aI. 1976) to aquatic environments can cause heavy metal loads to rise far above natural levels, with subsequent effects on the ecology of the area …

Polymer impregnation of concrete as a means of improving corrosion resistance
… chemicals, more commonly associated with industrial effluents. This is all discussed more fully in later sections.

Agricultural and forest land runoff in upper South River near Waynesboro, Virginia
… and urban land drainage as well as domestic and industrial wastewater effluents. The yields of materials from the various sources were computed during an intense storm in May, wet weather flow in June, and dry weather flow in July. During the short term period of high storm flows, land runoff was …

Development and application of a three-dimensional water quality model in a partially-mixed estuary, Southampton Water, UK
… inputs from external sources (rivers, sewage and industrial effluents) and that the summer increase in the lower estuary is a consequence of phytoplankton photosynthesis. Nutrients in the Itchen Estuary and Southampton Water show mainly conservative behaviour in a plot of nutrient concentration …

The feasibility of reverse osmosis as a water reclamation process with special reference to the rejection of organic compounds
… water economy, mainly for the treatment of industrial effluents and, in the longer term, for the reclamation of water from sewage effluents and for the treatment of effluents and recycled water in indirect water reuse situations. A cost analysis showed that reverse osmosis could become …

A Systems Analysis of Trace Element Cycling in the Great Lakes
… and agriculture; anthropogenic waste steams (industrial effluents, agriculture runoff) impact occurrence patterns and natural cycles of various chemical elements, however current baseline concentrations remain unknown and biogeochemical controls underlying their sources, mobility, and fate …

Studies of the complexation behaviour of transition metals applicable in membrane technologies
Many industrial processes make use of metal ions. These metal ions, however, end up in several effluent streams. Due to very strict discharge values, new technologies are constantly emerging for treating and purifying all kinds of wastewater. One of these innovative technologies is the Supported …

Development of ultrasensitive electrochemical sensors based on nanocomposites for environmental applications
… water is a crucial water problem generated from industrial effluents, mining wastes, or domestic sewage, and the widespread use of pesticides in pest control in the environment. In the last years, heavy metals have risen significantly, especially in the developed country where most pollutants are …

Environmentally-sensitive river management : assessment and mitigation of impacts on urban rivers
… the disposal of unpurified sewage and industrial effluents, removal of riparian forests, clearing of instream vegetation and the draining of wetlands. During the 20111 century, many urban rivers have been "improved" by straightening or confining within rectangular concrete-lined canals …

Enhanced large-scale production of laccases from Coriolopsis polyzona for use in dye bioremediation
… pulping plants, draws major concern. Textile effluents have negative impact both on the environment and human health because they are toxic and some are carcinogenic. Apart from the textile industry, dyes are also widely used in manufacturing industries for leather products, cosmetics, …

Investigation into three potential modifying factors in larval fathead minnow (Pimephales promelas) growth and survival
… larvae. However, in subchronic tests with industrial effluents, prior MB exposure resulted in lowered survival or lowered growth, but did not increase sensitivity to the effluent. Lowered growth and survival was observed in blue- dyed individuals from larval populations exposed to MB during …
