  • 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 ...

  • A case study of the sludge thickener - Large Commercial Facility (Office Building)

    Costs for industrial waste reduced with sludge thickener Some office buildings and large commercial facilities have wastewater treatment facilities underground. In such case, it is difficult to take dewatered cake out, so sludge is kept in liquid form and vacuumed out by pump without being dewatered. This potential customer also had been vacuuming out the liquid sludge, and had considered how to ...

  • Application of forward osmosis (FO) under ultrasonication on sludge thickening of waste activated sludge

    Forward osmosis (FO) is an emerging process for dewatering solid–liquid stream which has the potential to be innovative and sustainable. However, the applications have still been hindered by low water flux and membrane fouling when activated sludge is used as the feed solution due to bound water from microbial cells. Hence, a novel strategy was designed to increase sludge thickening and reduce ...

  • Direct Dewatering from Oxidation Ditch (Africa)

    Development of proper sanitation or wastewater treatment has been a critical issue in Africa for prevention of almost any types of infectious diseases. Generally, anywhere in the world, the keys for the successful wastewater treatment system is choosing the appropriate solids removal and dewatering technology and achieving the acceptable quality of water for discharge. However, the high ...

  • Growth of microalgal biomass on supernatant from biosolid dewatering

    The paper reports the results of an experiment to assess the feasibility of including a photobioreactor within the design of a wastewater treatment plant, growing microalgae on the centrate from anaerobic sludge dewatering. The growth of algal biomass would take advantage of the available nitrogen and provide a substrate for biogas production by anaerobic digestion. Tests were carried out by ...

  • Lab-scaled digestibility study of wastewater sludge treated by thermal hydrolysis

    ABSTRACT High-solids mesophilic anaerobic digestion (HS-MAD) processes employing thermal hydrolytic pretreatment (THP) have gained much interest in recent years; primarily because they have been shown to produce Class A biosolids in accordance with EPA 503 regulations, but also because they represent an economical approach to the maximization of available anaerobic digester volume. The ...

  • You can dewater your cake and pump it too! Conveyance options for OCSD Plant 1

    OCSD is currently upgrading Reclamation Plant 1 to co-thicken primary and waste activated solids using centrifuges. Digested solids will also be dewatered using centrifuges and the two processes will be housed in the same building. A small building footprint, stringent redundancy requirements, and a 200 foot distance between the dewatering and storage facilities requires innovative engineering ...

  • 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 ...

  • Effect of Microsludge on Anaerobic Digester Performance and Residuals Dewatering at La County’s JWPCP

    MicroSludge™ is a patented chemical and pressure pretreatment process that liquefies waste activated sludge (WAS) to increase both the rate and extent that it is degraded in a conventional mesophilic anaerobic digester (CMAD). The process uses chemical pretreatment to weaken cell membranes and a high-pressure homogenizer, or “celldisrupter”, to provide an enormous and sudden pressure change to ...

  • Lagoon and Ditch Sediment Dewatering Utilizing Geotube Preliminary Pilot Demonstration - Case Study

    Project Background Geotubes have proven to be a practical and economical way of dewatering a number of domestic and industrial sludges, and sediments, such as river and lake sediments and contaminates, wastewater lagoon sludge, water treatment plant sludge, packinghouse sludges and wood products sludges. The Michigan Department of Environmental Quality (MDEQ) is interested in evaluating ...

  • Addressing digester foaming by fixing activated sludge system and gaining capacity in both

    The City of Richland Wastewater Treatment Facility digesters have experienced Nocardiainduced digester foaming problems from the time they went into operation in 1985. Because of the persistent foam, most or all of the thickened waste activated sludge (TWAS) was often not sent to the digesters but directly to the belt filter press to be dewatered separately from the digested sludge. It was ...

  • Nakanojo wastewater treatment plant case study

    "We wonder why others don't use Volute." Nakanojo town, nestled along streams in Gunma prefecture, has seven wastewater treatment plants. Among them, Nakanojo wastewater treatment plant is the biggest municipal plant serving 5000 population equivalent. Nakanojo is the municipality where "Volute", originally intended for use in industrial applications, was installed for the ...

  • The Effect of the Microsludgetm Treatment Process on Anaerobic Digestion Performance

    ABSTRACT Thickened waste activated sludge (TWAS) from biological treatment processes is less amenable to anaerobic digestion than primary sludge. This is due to TWAS being composed mostly of cellular material and extracellular polymeric substances (EPS) instead of more easily digestible carbohydrates and fats that are typically found in primary sludge. In an attempt to improve TWAS digestion ...
