  author={Silvie Hartmann and Hana {\vS}krob{\'a}nkov{\'a} and Jarmila Drozdov{\'a}},
Inhibition of the respiration microbial activity in the activated sludge caused by heavy metal concentrations (Cr, Cd, Cu and Ni) was studied by means of respirometric method using Strathtox respirometer (Strathkelvin Glasgow).The studied sludge samples were obtained from the two waste water treatment plants with different types of pollution (municipal waste water and domestic waste water). Keywords—heavy metals; toxicity; respirometry; sludge; waste water treatment plant

Evaluation of Heavy Metal Removal from Wastewater in a Modified Packed Bed Biofilm Reactor
The PBBR biological system, in the presence of high surface area carrier media and a high microbial population to the tune of 10 000 (mg/l), is capable of removing the industrial contamination in wastewater. Expand
Combined effect of heavy metals on the activated sludge process
Migration of heavy metals in the environment is a serious problem for wastewater treatment plants (WWTP) and the environment as a whole. The combined effect of eight heavy metals on the biologicalExpand
A Study of Toxic Dosage of Combined Selenium and Hexavalent Chromium on Activated Sludge Bacteria
The toxic impact of combined selenium (Se) and hexavalent chromium (Cr6+) salts on activated sludge from a local wastewater treatment facility has been studied through respiration inhibition tests.Expand
Nitrite Accumulation at Low Copper Concentration in a Submerged Partial Bionitrification Reactor
Methods : Experiments were carried out at the constant operational conditions (T=35°C; pH=9.0 and DO=2.0 mg O2/L) by varying the concentrations between 5-50 mg Cu /L. The SPBNR, which was operated inExpand
Inhibition of the partial nitritation by roxithromycin and Cu(II).
To facilitate the application of partial nitritation (PN) - anaerobic ammonium oxidation process in nitrogen removal from livestock wastewater, the inhibition of roxithromycin (ROX) and Cu(II) on theExpand
Metal residues in macroalgae feedstock and implications for microbial fermentation
Abstract Macroalgae cultivation shows potential for the application as emerging feedstock for microbial fermentation to produce biochemicals. However, metal residues in macroalgae might affect theExpand
Functional categories of microbial toxicity resulting from three advanced oxidation process treatments during management and disposal of contaminated water.
The results indicate that AOP pre-treatment can be a viable strategy to facilitate drain disposal of contaminated waters, but that eco-toxicity may remain a concern. Expand

Heavy metal shock load in activated sludge uptake and toxic effects
Abstract Waste sludge from laboratory units at four different steady-state conditions (5–20 days sludge ages) was employed for studying heavy metal shock load by the jar test system. Metal uptakeExpand
Effect of acclimatization of microorganisms to heavy metals on the performance of activated sludge process.
The time period necessary for acclimatization of seed MOs must be adjusted carefully with concentrations of HMs lower than their threshold concentrations to achieve an optimal operation of an aerobic biological process. Expand
Response of sOUR and AUR to heavy metal contamination in activated sludge
Abstract The aim of this work was to make a contribution to the knowledge of inhibition by heavy metals of both nitrifying and heterotrophic bacteria in the activated sludge, based on measurements ofExpand
Effects of nickel(II) addition on the activity of activated sludge microorganisms and activated sludge process.
Termination of Ni(II) addition led to almost full recovery of the bioactivity in microorganisms as shown in the increase of specific oxygen uptake rate (SOUR) and SBR treatment performance. Expand
The immunochemical detection of stress proteins in activated sludge exposed to toxic chemicals.
The heat shock protein, GroEL, was found to be induced in activated sludge cultures exposed to perturbations of chemicals or heat stress, but it is indicated that GroEL may not be a good candidate protein for this purpose. Expand
Toxicity of copper(II) ions to microorganisms in biological wastewater treatment systems.
The results of the batch bioassays indicated that copper(II) caused severe inhibition of key microbial populations in wastewater treatment systems, and denitrifying and nitrifying bacteria showed considerable recovery of their metabolic activity after only several days of exposure to high copper levels.

Inhibition of respiration and distribution of Cd, Pb, Hg, Ag and Cr species in a nitrifying sludge.
Investigation of the inhibitory effects of the heavy metals Cd, Pb, Hg, Ag and Cr on a nitrifying sludge highlighted that IC(50) values alone do not have an explanatory power of inhibition unless speciation is also considered. Expand

The heavy metals include metalloid substances that exhibit similar properties in the environment—typically high toxicity at low concentrations and with a long residence time in soil. Many industrialExpand
The role of respirometry in maximising aerobic treatment plant efficiency
Wastewater treatment plants are coming under increasing pressure to increase their efficiency of operation. There are two objectives in this. The first is to reduce the cost of treatment. The secondExpand
Effect of cadmium on composition and diversity of bacterial communities in activated sludges
Cadmium was significantly toxic to the bacterial community in nutrient removal sludge, especially to the bacteria in the Betaproteobacteria, and the comparison of microbial communities between these two kinds of sludge was further discussed in the paper. Expand
