  • Environmental sludge treatment

    During the process of wastewater treatment, sludge generation is an important and at times crucial issue to be addressed as inadequate sludge handling system can pose serious environmental implications. Liquid sludge can be easily thickened and reduced to a solid cake via sludge thickening / dewatering. This reduces the volume of liquid sludge significantly, usually resulting in a quite ...

  • Sewage sludge and waterworks sludge stabilization in sludge treatment reed bed systems

    In this study, results about sludge stabilization in sludge treatment reed bed (STRB) systems in two different systems, Hanningfield STRB 1 (England), treating waterworks sludge, and Stenlille STRB 2 (Denmark), treating surplus activated sludge, are presented. The study mainly focused on the effectiveness of the STRBs systems in stabilizing sludge organic matter; in fact, parameters correlated ...

  • Ultrasonic Waste and Sludge Treatment

    Biogas is generated from sources, such as municipal organic waste, sewage sludge, muck or manure. Ultrasonication improves the digestibility of such organic material leading to more biogas and less residual sludge. Biogas is a byproduct of the decomposition of organic matter by anaerobic or aerobic bacteria. It consists primarily of methane, carbon dioxide and hydrogen sulfide. This makes biogas ...

  • Sludge Treatment and Disposal Technologies

    Most wastewater treatment processes produce a by-product that purifies wastewater before it is released into local waterways. This by-product is named as sludge. Typically in solid, semi-solid or liquid state, it is in fact an amalgamation of all the liquid wastes that are discharged by domestic houses, commercial properties, industry, and/or agriculture after aerobic biological treatment. ...

  • Comparing Sludge Removal Systems For Water Treatment Plants

    Due to limited clearance and accessibility, effective removal of settled sludge beneath tube settlers has long been a challenge for plant owners and design engineers. They needed a sludge removal solution with a low-profile design that would offer flexibility during operation and maintenance. In 2012, Brentwood introduced a new sludge removal system to fill those needs ─  ...

  • Economic assessment of sludge handling and environmental impact of sludge treatment in a reed bed system

    The effect on the environment of the establishment and operation of a sludge treatment reed bed system (STRB) is quite limited compared to mechanical sludge dewatering, with its accompanying use of energy and chemicals. The assessment presented here of the investment, operation and maintenance costs of a typical STRB, and of the related environmental impact, is based on the experiences gained ...

  • Reed bed systems for sludge treatment: case studies in Italy

    In recent years, reed bed systems (RBSs) have been widely considered as a valid technology for sludge treatment. In this study are presented results about sludge stabilization occurring within beds in four RBSs, situated in Tuscany (Italy). The results showed that stabilization of the sludge over time occurred in all RBSs, as shown by the low content of water-soluble carbon and dehydrogenase ...

  • Quantifying Sludge Production in Municipal Treatment Plants

    ABSTRACT This paper addresses the issue of sludge production in plants treating municipal wastewater. The historical understanding and quantification of sludge production in activated sludge systems is reviewed briefly. An important factor is the selection of three parameters used in the estimation of sludge production (and carbonaceous oxygen requirements). These are the yield coefficient ...

  • In Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • Dewatering sludge originating in water treatment works in reed bed systems

    The dewatering process of the liquid water works sludge was examined in a trial with a series of six trial beds, each 20 m2. These were monitored from April 2008 to June 2010. It is possible to get the vegetation to grow in ferric sludge (∼300,000 mg Fe/kg dry solid, pH 7,7). It has not been necessary to use fertilizer. The influence of the loading programs (15–50 kg dry solid/m2/year) was tested ...

  • High efficiency odour control for sludge dryers, sludge pasteurizers and sludge stabilisation using lime and biogas treatment

    Abstract This paper summarizes ERG’s experience of supplying odour control for sludge dryers, sludge pasteurizers, sludge lime stabilization and biogas treatment and indicates areas for improvement.   Keywords Odour control, chemical scrubbing, carbon filters, waste water, OdorgardTM, sludge dryers, sludge pasteurizers, lime ...

  • Common Treatment Technologies for Fuels in Soil, Sediment, and Sludge

    Common treatment technologies for fuels in soil, sediment, and sludge include biodegradation, incineration, SVE, and low temperature thermal desorption. Incineration is typically used when chlorinated SVOCs are also present with fuel, and not specified for fuel-only contaminated soil, sediment, or sludge. All types of biodegradation, both in situ or ex situ, can be used to remediate soils: ...

  • Centralised treatment of oil sludge and other industrial waste

    Centralised treatment of various sources of industrial waste has been established in many European countries over the last decade. Many facilities are still equipped with non state of the art technology and therefore cannot fulfil the broad field of applications with regard to industrial waste remediation. econ's international client decided to be one step ahead and erected a new econ industries ...

  • Water treatment plant sludge disposal into stabilization ponds

    Researchers have paid particular attention to the disposal of sludge produced in water treatment plants (WTPs) into wastewater treatment plants (WWTPs) for further processing, mainly because it is considered an attractive alternative for the treatment of waste generated in water production processes. This study evaluated the effects of flow equalization and disposal of sludge, from a ...

  • Gas composition of sludge residue profiles in a sludge treatment reed bed between loadings

    Treatment of sludge in sludge treatment reed bed systems includes dewatering and mineralization. The mineralization process, which is driven by microorganisms, produces different gas species as by-products. The pore space composition of the gas species provides useful information on the biological processes occurring in the sludge residue. In this study, we measured the change in composition ...

  • Robust systems for optimal treatment - Case Study

    Big Park Domestic Wastewater Improvement District in Arizona had constructed a new 500,000 gallons per day biological wastewater treatment system in 1997. As time passed, the aging plant was unable to keep up with increasing demands. Challenges In 2012, the District started working with Sunrise Engineering to find a solution that would work in their existing plant. Sunrise ...

  • Greywater treatment in an aerobic SBR: sludge structure and kinetics

    In order to have an efficient operation, sequencing batch reactors (SBR) must support granular biomass with high conversion rates, settling properties, and be able to deal with the inherent variability of the composition of real wastewaters. In this study, the effect of the influent composition and the specific organic loading rate (Bx) on the granulation process was evaluated in two SBRs, ...
