Preliminary

This service was made according to customer order points and indications from Hydrolab Microbiológica (Surcis collaborator)

The client wanted Surcis to carry out a study about COD fractioning and nitrification.
For this study the client has provided to Surcis the following:

  • Process type: Activated sludge - Extended aeration
  • 2 wastewater samples: the first one is a punctual sample from an irregular wastewater influent (sample 1) and the second one is coming from one-day composite wastewater from the normal influent to the activated sludge process (sample 2)
  • Activated sludge from the biological reactor.
  • Some wastewater data in the process.

Date of the study: weeks 17 (April) and 18 (May) - 2012

Note: As usual, in the complete report presented to the client, Hydrolab Microniológica could also include a part of the microscopic bio-indication.

    Microscopic versus qPCR (quantitative polymerase chain reaction) analyses were compared for the detection of Didymosphenia geminata in biofilms and water filtrates from seven Gaspésie rivers (Canada). For the qPCR approach, two DNA extraction kits (QIAamp DNA Micro Kit, Qiagen and PowerSoil DNA Isolation Kit, Mo Bio Laboratories) and two pairs of primers were considered. The pair of primers D602F/D753Rext did not amplify D. geminata DNA whereas the pair of primers D602F/D753R was specific for D. geminata. Presence-...

    For the efficient removal of some anionic dyes, a novel adsorbent was developed. The adsorbent was prepared by coating a synthetic polymer on magnetite nanosphere surface as a magnetic carrier. The synthesized nano-adsorbent was fully characterized using Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometer, X-ray diffractometer, scanning electron microscope, and transmission electronic microscopy measurements. The synthesized nano-adsorbent showed high adsorption capacity towards removal...

  • Response surface modeling of bioremediation of acid black 52 dye using Aspergillus flavus

    Bioremediation is an efficient process to remove metals and dyes from solutions using different micro-organisms. In the present study, the efficiency of growing Aspergillus flavus (isolated from the effluent of an electroplating industry) to treat a synthetic solution of acid black 52 dye (a trivalent chromium complex dye) was investigated. Maximum removal of dye and chromium was observed to be 390 and 17.22 mg/L, respectively, at an initial dye concentration of 750 mg/L and at pH 4.5 in 50 hours in a batch...

    In this paper, goethite waste from hydrometallurgy of zinc was used as a raw material for arsenic adsorbent preparation. The goethite waste adsorbent (GWA) was characterized with scanning electron microscope (SEM), X-ray powder diffraction (XRD), and particle size distribution analysis. The adsorption of As(III) on GWA was studied as a function of contact time, pH, and coexisting anions. The safety of GWA usage in the wastewater treatment process was assessed by toxicity characteristic leaching procedure (TCLP)...

    The utilization of magnesium hydroxide was successfully carried out to remove reactive orange by coagulation-adsorption from aqueous solution. The coagulation-adsorption mechanisms and magnesium hydroxide-reactive orange floc property were analyzed through zeta potential, scanning electron microscope (SEM), X-ray diffraction and Fourier transform infrared spectroscopy (FT-IR). Flocculation Index was then discussed with controlled experiments using intelligent Particle Dispersion Analyzer (iPDA) and optimum rapid...
