Polycyclic aromatic hydrocarbons (PAHs) are organic compounds widely distributed in the  environment.  In  the  present  work, concentrations  of  these  organic  compounds  in  sludge samples  from  Cluj-Napoca  wastewater  treatment  plant  are  reported.  The  objective  was  to investigate PAHs in sludge from wastewater treatment plant and to assess their potential for land application. Primary sludge, fermented sludge, fermented concentrated sludge, anaerobic-digested dehydrated  sludge  and  rejection  water  samples  were  collected  monthly  from  December  2012. Ultrasonic assisted extraction with hexane was used, being followed by filtration and concentration to  dryness  in  a  rotary  evaporator;  the  obtained  residue  was  redisolved  in  acetonitrile.  High performance  liquid  chromatographic  analysis  was  achieved  using  an  Agilent  1100  system consisting in a solvent degasser, a quaternary pumping system, an autosampler, a column oven, a diode-array  detector  and  a  fluorescence  detector.  Separations  were  accomplished  using  an Envirosep  PP  column  with  acetonitrile:water  as  mobile  phase  (45:55  v/v).  Detection  limit  was 0.001 g/  kg,  with  good  linearities  for all  PAHs,  with  correlation  coefficients  higher  than  0.998. PAHs with four rings appeared to be the primary components in most of the tested sludge samples, the  highest  concentration  levels  being  in  anaerobic-digested  dehydrated  sludge  samples.  The obtained results can be helpful for the regional policy makers to make proper decisions on treating the  increasing  amount  of  sewage  sludge,  to  provide  practical  reference  for  establishing  threshold values  of  PAHs  for  land  application  of  sludge,  knowing  that  the  practice  of  recycling  sewage sludge onto agricultural lands poses an additional risk of soil contamination with PAHs.

Limiting Factor

To reuse municipal sewage sludge safely, experiment was carried out on grapefruit trees fertilized with composted sludge from Shiweitou Sewage Treatment Plant in Xiamen City of China, and a method was introduced of how to assess the environmental quality of grapefruit trees soil fertilized with sludge by Set Pair Analysis (SPA) model. The results showed that the soil in the surface layer (0-15cm) and the deeper layer (15-30cm) was less clean, and the environment of soil was not polluted. Thus it was feasible to use sludge as fruit fertilizer. The maximum service life of sludge for continuous land application was estimated by taking Cd as the limiting factor, which would provide scientific guide and technical support for safe land application of sludge.

Several process units at a wastewater treatment plant (WWTP) can produce a significant level of sound and thus induce sound nuisance for nearby residents. The risk for sound nuisance should be considered by making a prognosis of sound impact in an early project phase (planning, design). A prognosis requires information with respect to the sound characteristics of the different process units. This paper reports the development of empirical models for the sound power of relevant process units in the water line at Aquafin WWTPs. The used methodology for model derivation and validation allowed us to minimize the required number of measurements. Besides the methodology, the paper describes in detail the derivation and validation of the empirical model for the splashing water of screw pumps. Also the use of all the derived empirical models to determine the sound impact of a wastewater treatment plant at close distance is illustrated with a case-study.

Dissolved air flotation (DAF) incorporating filtration (DAFF) is used at the Bolivar wastewater treatment plant (WWTP) to polish lagoon effluent for reuse. Elevated algal populations are frequently experienced and can lead to increased coagulant requirements and process control issues. Streaming current detectors (SCDs) and a charge demand analyser (CDA) were used to monitor the full-scale plant. This was followed by an optimisation study using a pilot plant with a CDA. It was found that the normal operational charge demand range for DAF at Bolivar was between −46 and −40 μeq L−1. Decreasing the pH of coagulation reduced coagulant consumption and facilitated more sensitive CDA responses to changes in alum dose.
