Nutrient removal from activated sludge mixed liquor by wastewater protozoa in a laboratory scale batch reactor

The aim of the study was to investigate the nutrient removal rate of three wastewater protozoan isolates (Aspidisca, Trachelophyllum and Peranema). The study was carried out in a laboratory-scale batch reactor for a period of 120 h. in a four batch study. Aliquot samples were withdrawn from the reactor every 24 h. for the analysis of phosphate, nitrate, nitrite, ammonia, chemical oxygen demand,...

Coagulation in a Continuously Stirred Tank Reactor

Smoluchowski 's coagulation equation with coagulation rates K 0 oc (ij) ~ describing the temporal evaluation of the size distribution ck (concentration of k-mers) is studied in the presence of a source term ark, and a sink term --bCk. With a' a/b 2 one finds that a steady state is reached, exhibiting gelation when w > 1⁄2 and a ' > ao(w), where a0(o~) depends on w (ao(w) = ~ for ~o < 1⁄2, ao(1)...

Removal of ammonium and phosphate from the supernatant of anaerobically digested waste activated sludge by chemical precipitation.

The removal of ammonium (NH(4)(+)) and phosphate (PO(4)(3-)) from supernatant of anaerobic digestion by magnesium ammonium phosphate (MAP) formation was studied. To be able to find out the loss of NH(4)(+) by its transformation to NH(3), rates of NH(4)(+) removal by aeration and by MAP formation combined with aeration were compared. NH(4)(+) removal by aeration was found to be insignificant. Th...

Simulation Analyses of Continuous Stirred Tank Reactor

This paper presents simulation experiments on the continuous stirred tank reactor (CSTR) which is widely used equipment mainly in the chemical industry. The behaviour of these types of systems is usually nonlinear with other negative properties such as a time-delay or a non-minimum phase behaviour and simulation could help us with the understanding of them without making real experiments which ...

Cu2+ removal and recovery by Spi SORB: batch stirred and up-flow packed bed columnar reactor systems.

The biosorption of Cu(2+) by free and poly acrylamide gel (PAG) immobilized Spirulina platensis (SpiSORB) was characterized under batch and continuous packed bed columnar reaction systems. The biosorption of Cu(2+) was shown to be highest at pH of 6.0 for both types of biomass. The PAG immobilization process did not interfere with the Cu(2+) binding sites present on biomass leading to cent perc...
