biological treatment options of multiple myeloma
… Bortezomib is the predominant choice in treatment regimens. The basic action of proteosome inhibitors is to inhibit the degradation of proteins within the cell nucleus leading to the accumulation of proteins within the endoplasmic reticulum, The build up of folded and unfolded proteins …

Aerobic biological treatment of a colloidal wastewater
… type experiments were conducted on two model treatment units. One unit was similar to a completely mixed activated sludge process, and the other a model of the contact stabilization process. Both of these units were operated at steady state conditions on a sludge age basis to compare treatment …

Biological treatment and recycling of textile processing effluents
… to develop a continuous 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 …

Chemical And Biological Treatment Of Mature Landfill Leachate
The challenges imposed on Voltage Regulator Modules (VRM) become difficult to be achieved with the conventional multiphase buck converter commonly used on PC motherboards. For faster data transfer, a decrease in the output voltage is needed. This decrease causes small duty cycle that is accompanied …

An investigation into biological treatment of fruit cannery wastes
… load. Usually the municipal waste water treatment facilities are inadequate to handle the seasonal peak loads. This, in conjunction with the nutrient deficient nature of the cannery wastes, results in poor treatment efficiencies being recorded at the purification works.

Enhancing Aquaculture Sustainability Through Water Reuse and Biological Treatment
… More specifically, by using suspended-growth biological reactors to treat a tilapia effluent waste stream and to generate microbial flocs that could be used to support shrimp culture. This RAS technology will decrease water consumption by increasing the amount of recycled water and will also …

Biological treatment schemes for preventing oxime inhibition of nitrification
… a single sludge multi-environment anoxic/aerobic biological treatment scheme that could achieve oxime degradation and nitrification in the same treatment process. Aerobic and anoxic batch experiments were initially performed to determine degrees of nitrification inhibition caused by three oximes, …

Low temperature biological treatment of a high ammonia municipal landfill leachate
The single-sludge, biological pre-denitrification (i.e., denitrification being carried out be-fore nitrification), completely-mixed activated sludge system, with hydraulic sludge recycle, known as the Modified Ludzack-Ettinger (MLE) system, has proved to be an efficient method for ammonia nitrogen …

Mathematical modelling of integrated chemical, physical and biological treatment of wastewaters
… model to simulate chemical, physical and biological processes in three phase (gaseous-aqueous-solid) mixed weak acid/base systems is described. The chemical processes are expressed in terms of the kinetics of the forward and reverse reactions for the dissociation of the weak acid/bases. In …

Physicochemical and biological treatment of a textile dyeing and finishing wastewater
… in color, organic matter, metals and toxicity. Treatment is usually required before discharge into a sewer or body of water. Pretreatment often consists of chemical coagulation to remove color and solid matter. Aerobic biological treatment is incorporated to remove degradable organic matter and …

Novel Reactors for Biological Treatment of High Strength Nitrogen and Carbon Wastewater
… we assessed the performance of three different biological systems to achieve near full nitrogen (N) and carbon (C) removal from high-strength N wastewaters with low C/N ratio. The first objective was to demonstrate long-term operation of a simple two-stage partial nitrification-anammox reactor …

Biological Treatment of Reclamation of Industrial Wasterwater From Post-Combustion Carbon Capture
… and human health. This study will focus on the biological treatment of two contaminants: amines and sulfates. The main objective of this study is to design and develop an effective biological system to treat CCS wastewater to a quality that can be recycled back to the CCS process economically. …

Soil washing and post-wash biological treatment of petroleum hydrocarbon contaminated soils
… soils by soil washing and subsequent biological treatment of the different soil fractions. In addition to soils obtained from contaminated sites, studies were also performed on soils contaminated in the laboratory. Soil washing was performed using a bench-scale soil washing system. …

Removals of sulfonamide and trimethoprim antibiotics in municipal wastewater by biological treatment processes
… of bacteria. Although conventional wastewater treatment processes were not designed to eliminate trace chemical contaminants including antibiotics, selection of appropriate treatment processes and optimization of their operational conditions may enhance the removal of many of these substances. …

Biological treatment of waste solutions generated from the remediation of perchlorate-contaminated waters
… the feasibility of combining ion exchange and biological reduction to remove perchlorate contamination from waters and eliminate it from the environment. Perchlorate can be removed from water by ion exchange. However, regeneration of these resins creates a waste stream, concentrating the …

The experience of psoriatic arthritis patients receiving biological treatment : an interpretative phenomenological analysis
The recent development of biological therapies has revolutionized medical treatment for psoriatic arthritis. To date, research studies have focused on the treatment effects of biologics from a quantitative perspective using generic quality of life measures. An understanding of how treatment with …

Air stripping and biological treatment of ammonium sulfate wastewater from the caprolactam manufacturing process
… manufacturing process, to determine if biological nitrification is a viable means of treatment, and to identify any compounds present in the ammonium sulfate wastewater that (might) inhibit nitrification. This was accomplished using a combination of air stripping pretreatment, a …

Evaluation of three carbon sources for the biological treatment of acid mine drainage through process modelling
… of lime (Santos et al., 2004). More recently, biological treatment of AMO has become attractive. However, a concern with this method is the requirement and availability of cost effective and efficient sources of carbon and electron donors. This thesis aims to evaluate three different substrates …
