  • Containment for Soil, Sediment, and Sludge

    Containment treatments are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards, ...

  • How Tire Shredding Protects Wildlife

    One of the most revolutionary inventions in the history of mankind was the wheel, and the best upgrade to that invention was the rubber tire, which overcame the limitations of wooden or metal wheels and made it possible to have smooth rides at fast speeds. However, there is a significant drawback to using rubber tires: eventually, they get too worn out to be useful as tires anymore and have to ...

  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Management of sewage sludge and ash containing radioactive materials

    Approximately 50% of the seven to eight million metric tonnes of municipal sewage sludge produced annually in the US is reused. Beneficial uses of sewage sludge include agricultural land application, land reclamation, forestry, and various commercial applications. Excessive levels of contaminants, however, can limit the potential usefulness of land-applied sewage sludge. A recently completed ...

  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

  • Toxicity assessment and biodegradation potential of water-soluble sludge containing 2,4,6-trinitrotoluene

    The water-soluble phase of trinitrotoluene-containing sludge (SLP) was characterized with regard to trinitrotoluene (TNT) concentration, ecotoxicity, and a model biodegradation experiment as evaluation criteria for further development of appropriate treatment technologies. SLP contained 67.8 mg TNT/l. The results of germination and root-elongation tests indicated that SLP had a species-specific ...

  • Transportation and distribution of chromium in the anaerobic sludge treating the chromium-containing wastewater

    The chromium distribution and transportation in the anaerobic activated sludge was investigated using a sequential extraction method. The results showed that Cr(VI) in aqueous solution was reduced by the metabolic product of SRB and form indissoluble Cr(OH)3 in a solid phase. More than 99% of Cr(III) in the sludge was in a stable residual form (RES) of bio-reduction. The Cr(VI) was mainly present ...

  • New processes for the improvement of sludge digestion and sludge dewatering

    INTRODUCTIONThe examination of numerous sewage sludges from municipal wastewater treatment plants leads to the conclusion that on the one hand dewaterability of these sludges worsens and that on the other hand dewaterability of sludges becomes more and more important due to increasing disposal costs. Especially wastewater treatment plants with inflows from the food processing industry often face ...

  • Post-denitrification using alginate beads containing organic carbon and activated sludge microorganisms

    Nitrate concentration in the final effluent is a key issue in pre-denitrification biological treatment systems. This study investigated post-denitrification with alginate beads containing immobilized activated sludge microorganisms and organic carbon source. A batch study was first performed to identify suitable carbon sources among acetate, glucose, calcium tartrate, starch and canola oil on ...

  • Evaluation of the single sludge deammonification process for the treatment of plant recycle streams containing a high ammonium concentration

     ABSTRACT An innovative biological process for the treatment of ammonium-rich plant recycle streams from the dewatering of anaerobically digested sludges (“centrate” or “rejection water”) is being evaluated in North America in an unprecedented collaborative technology evaluation program between the New York City Department of Environmental Protection, the District of Columbia Water and ...

  • Performance of Upflow Anaerobic Sludge Blanket (UASB) reactor treating simulated wastewaters containing 1,1,2-Trichloroethane and 1,1,2,2-Tetrachloroethane

    Reactors R2 and R3 were investigated for biodegradation of 1,1,2-Trichloroethane and 1,1,2,2-Tetrachloroethane respectively, during acclimation phase. Reactor R1 was maintained as control. The stepwise increment in concentration of 1,1,2-TCA from 5 mg/L to 40 mg/L in R2 caused no inhibition to reactor performance. The percentage of 1,1,2-TCA and COD removal was 99.9% and 98.6%, respectively. ...

  • Impact of sludge retention time on sludge characteristics and microbial community in MBR

    In this study, the impact of sludge retention time (SRT) on sludge characteristics and microbial community and the effect on membrane fouling in membrane bioreactor (MBR) was investigated. The results show that MBR with longer SRT has less fouling propensity, in agreement with other studies, despite the fact that the MBR with longer SRT contained higher MLSS and smaller particle size. However, ...

  • Chopper Pumps: Pumping of septic sludge

    Landia chopper pumps have a great record of application in septic sludge. Septic sludge is raw unscreened sewage often delivered by tanker trucks from remote sites such as summer houses, camping sites, harbours, etc. Septic sludge contains many different solids tending to clog up pumps, everything people possibly can flush down a toilet! At this particular plant, a DG-I 4,0 kW –1500 kW was ...

  • Dewatering of Industrial Sludge - Case Study

    At Ten Cate Protect, town of Nijverdal, The Netherlands, 2006 During the wastewater treatment process at Ten Cate Protect large quantities of sewage sludge are liberated. A couple of days per week this sludge is transported in tanker trucks to a waste disposal plant. On June 14th 2005 a Geotube MDS unit was put in operation at Ten Cate Protect to separate and condense the sludge of the aerobic ...

  • Remediation of Oil Refinery Sludge Basin

    Abstract Work was completed in early 1992 to clean up a 5.5 acre (2.2 ha) stormwater sludge basin for an oil refinery company. The basin, which had served as a stormwater collection and settling pond for over 40 years, contained oily sludges with high concentrations of certain metals and volatile organic compounds. The closure plan included a combination cement-bentonite slurry wall and jet ...
