Azo textile dyes wastewater treatment with constructed wetlands : design and operation of experimental vertical-flow constructed wetlands applied for the treatment of azo textile dyes (with/without artificial wastewater)
… two different azo textile dyes with and without artificial wastewater for long periods of time through different operation modes such as contact and resting times, and loading rates, which has rarely been considered in previous research works. The corresponding key objectives are (a) to assess …

Biological regeneration of activated carbon
… of biologically removing phenol from an artificial wastewater in the absence of activated carbon. The data collected during this fermentation were logged on a PDP 11/40 minicomputer. Variables such as oxygen and carbon dioxide percent by volume evolved, the dissolved oxygen concentration, …

Fabrication of TIO₂-embedded PVDF membranes and their application in algae membrane bioreactor systems
… was cultivated in the MBR systems fed with artificial wastewater at a target solids retention time (SRT) of 25 days. Under steady-state conditions, the MBR systems had an average algae biomass concentration of 2350 mg/L (COD unit) with simultaneous removal of about 78% of phosphorus and 34% …

Die Bedeutung der wurzelassoziierten Mikroorganismen für die Stickstoffumsetzungen in Pflanzenkläranlagen
… establish the importance of this stimulation for wastewater purification in the root zone. Observations were carried out in a planted and an unplanted laboratory batch reactor incubated with an artificial wastewater with a high concentration of ammonia. Samples were taken at intervals of 10 mm …

The effects of rapid mixing on the coagulation and sedimentation of ultra-fine coal and clay particles
… loads of coal and clay particles in their wastewaters. Traditionally, the industry has employed primary sedimentation as the fundamental treatment scheme for these sediment-laden blackwaters. This study was undertaken to determine the effects of a combination of coagulant addition and rapid …

Assessment and characterization of dissolved organic nitrogen removal in simulated soil aquifer treatment systems
Treated wastewater (reclaimed water) is becoming more critical as an alternative water source due to population growth and extreme precipitation patterns. The more we rely on water reuse schemes, the more we have to expand our knowledge about the efficiency of treatment processes. As part of the …

Investigation of polyhydroxyalkanoate production by an activated sludge microbial consortium treating artificial dairy wastewater
… processing in Ireland, and the high organic load wastewaters generated, represent an excellent potential substrate for bioconversion to PHAs in a mixed culture system. The current study sought to investigate the potential for such bioconversion in a laboratory scale biological system and to …

Efficiency of soil aquifer treatment in the removal of wastewater contaminants and endocrine disruptors. A study on the removal of triclocarban and estrogens and the effect of chemical oxygen demand and hydraulic loading rates on the reduction of organics and nutrients in the unsaturated and saturated zones of the aquifer.
… (SAT) under different loading regimes, using wastewater of much higher strength than usually encountered in SAT systems, and also to investigate the removal of the endocrine disruptors triclocarban (TCC), estrone (E1), 17¿-estradiol (E2) and 17¿- ethinylestradiol (EE2). SAT was simulated in …
