Challenges Extended periods of mismanagement from previous owners left the facility and the wastewater treatment system in disarray. ...

  • Pulp & Paper Water Treatment - A look at optimizing water resource management

    Application Case Study (Pulp/Paper Operations) The pulp and paper industry has traditionally been a consumer of large amounts of fresh water and power. Recently, increased focus has been given to the optimized efficiency of paper mills and to the environmental sustainability footprint of the industry. Therefore, water resource management has become a more critical factor ...

  • 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. ...

  • 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 ...

  • Thermophilic digestion revisited

    On the 28th of October Colsen presented their practical experience in the field of anaerobic sludge digestion at the Ghent symposium Valorization of organic resources from wastewater. At the symposium various speakers presented its view or experience on the topic of valorization of organic resources from wastewater. Numerous examples are being developed by companies and universities ...

  • White Paper: Cyclical Aeration Control- Combining Aerobic & Anoxic Conditions in One Basin

    Increase Water Quality with Cyclical Aeration With increased effluent pollution restrictions on municipal wastewater treatment plants, cities are pressed to find ways to economically increase their effluent quality with little to no funding. Many new NPDES permits ...

  • Seven Ways Your Facility Isn’t Meeting Effluent Regulations and How to Solve Them

    Whether you own, operate, or help manage a municipal or industrial facility that deals with wastewater, it’s important to understand how wastewater treatment can play a significant role in the overall health of your business, especially when it comes to meeting effluent regulations. This is an important part of the wastewater treatment process to consider, as ignoring it could earn your ...

  • Case study - Procurement and installation of a Biogas desulphurization unit at the Chania WWTP

    A proposal based on Bioconservacion’s technology was selected as the winning bid in the public tender released in 2015, covering the design, procurement and construction of a biogas desulfurizing unit to be installed in the waste water treatment plant in Chania, Greece. With a population over 100,000, Chania is the second largest municipality in the Greek island of Crete. Its waste water ...

  • 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 ...

  • 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 ...

  • Comparative applications of bioreactor and shake-flask systems in the laboratory treatment of oily sludge

    This study investigates the remediation efficiencies of a locally fabricated bioreactor system and a shake-flask system, using samples of oily sludge with varying concentrations of NPK fertiliser. Hydrocarbon removal efficiency of 46% and 24.2% was recorded for the stirred slurries containing 15- and 0-g NPK, respectively, in the bioreactor; whereas values of 40.1%, 33.2% and 18.9%, respectively, ...

  • 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 ...

  • 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 ...

  • 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: ...
