  • The thin-layer drying characteristics of sewage sludge by the appropriate foaming pretreatment

    As dewatered sludge is highly viscous and sticky, the combination of foaming pretreatment and drying process seems to be an alternative method to improve the drying performance of dewatered sludge. In this study, CaO addition followed by mechanical whipping was employed for foaming the dewatered sludge. It was found that the foams were stable and the diameters of bubbles mainly ranged from 0.1 ...

  • Dewatering Paper Mill Lagoon Sludge - Ancram, NY - Case Study

    Sludge from the secondary treatment system lagoon at the New York mill of Schweitzer-Mauduit International, Inc. had to be removed. Geotube technology with SmartFeed Chemical Conditioning System supporting technology was the most cost-effective and  efficient method  of containing  and dewatering the sludge. The dredging contractor removed 3,285 cubic yards of sludge from the ...

  • Rural community sewerage case study

    Succeeded in "zero-emission" of sludge Previously, sludge was vacuumed out in this treatment plant without being dewatered; however, the cost for sludge treatment was huge. Thus, aiming at "zero-emission" of sludge, fermentation of the sludge was being considered. AMCON's offer for a solution They introduced Dell Compo, which can treat sludge ...

  • Effect of synthetic cationic surfactants on dewaterability and settleability of activated sludge

    Dimeric cationic surfactants with different lengths of carbon chains were synthesised, and then these surfactants were added to the activated sludge samples to evaluate the dewaterability and settleability. The adsorbability of cationic surfactants on activated sludge was also studied. By comparing the dewatering performances of different cationic surfactants, the effect mechanisms of cationic ...

  • Sludge Dewatering Performance - A Survey Of Real Operational Performance

    Abstract. A survey of the literature revealed that it is difficult, indeed virtually impossible, to get meaningful information about the likely performance of dewatering equipment. As a consequence customers have sometimes specified impossible target  performances and suppliers have unwisely agreed to them. Dewatering has major consequences for downstream processes, for example sizing dryers ...

  • 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 ...

  • For Municipal Wastewater and Water Treatment, Geotube Dewatering Technology Works - Case Study

    For municipal wastewater or water treatment facilities, efficient dewatering can be a challenge. Space issues, personnel, and cost are all considerations, and an operation may experiment with a number of techniques before finding one that works. But dewatering technology from TenCate Geotube is proving to be a simple, cost-effective solution. Geotube2 dewatering technology has been used for a ...

  • Geotube Dewatering Technology contains and dewaters river sediments at large Water Treatment Plant in New Jersey - Case Study

    River sediments and filter backwash sludge are annually dredged and dewatered in Geotube containers for beneficial reuse. TenCate develops and produces materials that function to increase performance, reduce cost, and deliver measurable results by working with our customers to provide advanced solutions. And a unique high volume, low cost dewatering system from TenCate Geotube can ...

  • Effect of filter media thickness on the performance of sand drying beds used for faecal sludge management

    The effect of sand filter media thickness on the performance of faecal sludge (FS) drying beds was determined in terms of: dewatering time, contaminant load removal efficiency, solids generation rate, nutrient content and helminth eggs viability in the dried sludge. A mixture of ventilated improved pit latrine sludge and septage in the ratio 1:2 was dewatered using three pilot-scale sludge ...

  • Septic tank in Ukraine case study

    Ultra-small VOLUTE Dewatering Press ES-051 largely solves all the costs and maintenance problems. In the year of 2004 in Ukraine, there was no compact sludge dewatering equipment suitable for small-scale wastewater treatment facilities like septic tanks. As for septic tanks, it had been common that liquid sludge was disposed by tanker truck and delivered to central sludge ...

  • The effect of different percentages of bulking agent (sawdust) on microbial quality of faecal sludge

    The use of raw sludge spread on land as conditioner and fertilizer has been practised over the years in urban agriculture. However, this raw sludge (biosolids) is associated with a potential health risk as a result of the pathogenic microorganisms it contains. The study considered the dewatering of faecal sludge (FS) mixed with sawdust to produce biosolids that can be applied as manure for ...

  • Comparison of centrifuge and belt press for compressible digested sludge after thermal hydrolysis

    Abstract Historically it has been shown on many projects that centrifuges can outperform belt presses in dewatering digested sludge. However, results from a number of projects where sludege has been treated before digestion with Cambi thermal hydrolysis process (THP) hase shown good results for belt press dewatering - generally greater than 30% DS. The authors propose that the main mechanism in ...
