centrifuge-based liquid-solid separation system Articles

  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • Anaerobic Treatment in Decentralised and Source-Separation-Based Sanitation Concepts

    Anaerobic digestion of wastewater should be a core technology employed in decentralised sanitation systems especially when their objective is also resource conservation and reuse. The most efficient system involves separate collection and anaerobic digestion of the most concentrated domestic wastewater streams: black or brown water and solid fraction of kitchen waste. Separate collection using ...

  • The development and application of centrifugal flotation systems in wastewater treatment

    Flotation as a wastewater treatment technique is designed to remove all particles generally encountered as very fine emulsions, suspended solids, and colloids from wastewater. Historically, Dissolved Air Flotation (DAF) has been used to achieve this removal. More recently, other flotation techniques such as induced air, electro, cavitational, and Centrifugal Flotation Systems (CFS) have been ...

  • Optimizing drilling efficiencies with a solids control system

    The correct solids control system can improve drilling rig efficiency, reduce costs and minimize the environmental footprint of your operation Although the use of drilling fluids within the HDD / trenchless industry is still relatively new, recent trends suggest that this standard is shifting as solids control is one of the most important phases in the drilling process. This shift is due ...

  • Electrokinetic Separation

    Introduction The principle of electrokinetic remediation relies upon application of a low-intensity direct current through the soil between ceramic electrodes that are divided into a cathode array and an anode array. This mobilizes charged species, causing ions and water to move toward the electrodes. Metal ions, ammonium ions, and positively charged organic compounds move toward the cathode. ...

  • Disposal options for solid waste of Bangalore city based on its characteristics

    A detailed analysis of Bangalore's solid waste has been done to suggest various management options for safe disposal. It has been observed that Bangalore's solid waste contains a larger proportion of degradable waste compared to many other cities. Based on detailed analysis of available data, it has been suggested that a landfill with a leachate and gas collection system is better than an inert ...

  • What is a Mineral Thickener Tank

    The Thickener Tank is a solid-liquid separation device based on gravity sedimentation. It is usually a cylindrical shallow groove and a tapered bottom. It is made of concrete, wood or metal welded plates as a structural material. An excellent thickener brand needs to meet two basic indicators: good equipment quality and innovation. In addition ...

  • Principles of Solids Control

    Although the use of drilling fluids within the HDD / trenchless industry is still relatively new, recent trends suggest that this standard is shifting as solids control is one of the most important phases in the drilling process. This shift is due to a growing awareness that drilling fluid maintenance and disposal can become exponential problems as they are both harmful to the environment and ...

  • The Application of Waste Solids Management Vertical Cuttings Dryers as an integral element of a successful Solids Control System

    In Elgin’s last White Paper, “Common Challenges Relative to the Use of Decanter Centrifuges for Barite Recovery in the Oil & Gas Industry,” a detailed discussion was offered about the complexities involved in achieving effective solids control when deploying a dual-centrifuge “barite ...

  • The development and application of the hybrid centrifugal - dissolved air flotation system for wastewater treatment

    Abstract Solid/liquid separations are integral part of any wastewater treatment system. Particles heavier than water are commonly separated in sedimentation clarifiers. On the other hand, particles with densities lower than that of water are most often separated with flotation systems. This manuscript describes the development of hybrid centrifugal - dissolved air flotation system. The ...

  • A smarter approach to solids control

    When looking at technical brochures and marketing materials in regards to solids-control equipment, one question that should always come to mind should be: Is this really necessary? Other great questions to ask are: What are my day-to-day needs; and what are my severe, high-duty needs? Finding the right solidscontrol equipment is much like buying a personal automobile. Most vehicles’ ...

  • Centrifuge Technology in Drilling Fluid Recycling

    Drilling fluid additives and the water that contains them are an essential part and expense of successfully completing a horizontal directional drilling (HDD) installation, and the longer the bore and larger the product being installed, the more drilling fluids cost. Therefore, it makes economic sense to recycle drilling fluids by removing cuttings and recirculating the cleaned ...

  • Antifreeze Windshield Washing Liquid

    In cold season nonfreezing liquid for windshield washer along with gasoline are virtually the only consumable materials for a car. It seems impossible to not use this product, because it allows the driver to maintain visibility of the traffic situation and helps reduce the number of car accidents. Antifreeze is used in all cars regardless of their brand and ...

  • Cart-Based Organics Collection. Citizens Drive 65 Percent Diversion System

    For better or worse, citizens opposing waste management projects usually end up being labeled as NIMBYs — not in my backyard. This could have been the case in Halifax, Nova Scotia but instead, the citizens took their opposition one step further, basically taking the design for an acceptable waste management system into their own hands. In the process, they laid out the foundation for an ...

  • A real-time control strategy for separation of highly polluted storm water based on UV–Vis online measurements – from theory to operation

    ‘Classical’ real-time control (RTC) strategies in sewer systems are based on water level and flow measurements with the goal of activation of retention volume. The control system rule of ‘clean (storm water) runoff into the receiving water – polluted runoff into the treatment plant’ has been thwarted by rough operating conditions and lack of measurements. Due to the specific boundary conditions ...

  • Characterization of domestic graywater and graywater solids

    The knowledge of loads and concentrations is fundamental for the design of graywater treatment units, but the data on the characteristics of graywater and in particular graywater solids are weak. As general design values regarding graywater treatment facilities are not available for Germany, the objective of this article is to elaborate the characteristics of graywater and graywater solids. ...

  • Particle separation from road runoff by a decentralised lamella system – laboratory tests and experiences in the field

    A new decentralised settling system based on the principle of lamella separation was developed for the treatment of road runoff. Two different laboratory test methods, the DIBt (Deutsches Institut für Bautechnik) procedure and our own approach, were applied in order to evaluate the efficiency of the system based on the separation of fine mineral particles and a mixture of mineral and organic ...

  • Effect of co-managing organic waste using municipal wastewater and solid waste treatment systems in megacities

    A model was developed to calculate the mass and heat balances of wastewater and municipal solid waste treatment plants when these plants operate either separately or together with a mutual dependence on mass and energy. Then the energy consumption, life cycle costs (LCCs), greenhouse gas (GHG) emissions and effluent quality were evaluated under various scenarios to identify the most effective ...
