Characterization, Treatment, and Improvement of Aquacultural Effluents
During the water quality and sludge characterization phase, average effluent quality over the course of a day was not found to be impaired during a 7-month sampling and monitoring study at the three trout farms. However, effluent quality was found to change significantly during times of high farm …

Benthic Macroinvertebrate Susceptibility to Trout Farm Effluents
… stream. The main cause of mortality from trout effluents appears to be solids accumulating upon the organisms, and sedimentation basins should be effective best management practices for protecting macroinvertebrates.

Biological treatment and recycling of textile processing effluents
… culture system for the treatment of textile dye effluents. The bioprocess was optimised using biomass growth supports. The presence of a carbon source such as soluble wheat starch (0.2 % w/v) in dye solution media and effluent samples enhanced decolourisation. A polymer support (polyurethane …

Performance Characterization of Coagulation Pretreatment for Two Industrial Effluents
… 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 suspended solids, …

Land treatment of grape-processing effluents near Robertson, Western Cape
… treatment is the predominant disposal method of effluents generated by distilling, wine making and grape juice production in the Western Cape. Primary settling and treatment in aerobic and anaerobic lagoons typically precede disposal to land. Land treatment can effectively remove COD and also …

Removal of Perfluorooctane Sulfonate (PFOS) and Related Compounds From Industrial Effluents
… techniques for removing PFAS from industrial effluents are needed to minimize discharges of these pollutants. Reductive dehalogenation is widely applied to the degradation of highly chlorinated compounds. Hence, the susceptibility of PFOS and related compounds to biological and chemical …

Studies on the biological extraction of plant macronutrients from sewage effluents
… process for removing these elements from sewage effluents has not yet been reported. The investigations described here were carried out to determine the feasibility of using the nutritional requirements of controlled ecological systems for this purpose. The results are presented as an alternative …

Development of an invertebrate bioassay to screen petroleum refinery effluents discharged into freshwater
… for on-site toxicity testing of refinery effluents. This method will provide an inexpensive means of identifying problem materials and establishing priorities for coping with these materials. An arbitrary reference mixture (ARM), containing six common constituents of refinery wastewaters, …

The Use of a High Energy Feed for the Improvement of Trout Farm Effluents
… attention has been directed towards aquacultural effluents. The problem with the majority of these discharges is the solids and nutrient spikes that occur during times of high farm activity. Several studies have proven that these discharges have the potential to adversely affect downstream water …

Characterization of pond effluents and biological and physicochemical assessment of receiving waters in Ghana
… potential and actual impacts of pond aquaculture effluents on receiving stream quality in the Ashanti and Brong Ahafo regions of Ghana. Water, fish and macroinvertebrate samples were collected from upstream, downstream and nearby reference streams of, and questionnaires administered to, 32 farms. …
