  • Sludge Thickening an overview | ScienceDirect Topics

    The thickeners must be preceded by flow balancing tanks to contain and mix intermittent sludge discharges and feed the thickeners at a consistent concentration and uniform rate (Fig. 13.1). In applications where used washwater (without settlement) is mixed with clarifier sludge, the sizing of the flow balancing tanks becomes critical because of

  • What is the Sludge Thickening Process in Water Treatment

    Mar 06, 2018· Sludge thickening is an important process in treating solid waste. It minimizes the water waste, enabling the re-treatment of biosolids so that they can safely circulate back to waterways. It is vital to use the correct product and municipal wastewater treatment solution, so having an expert on hand will give your company the safeguards of

  • Sludge Thickening and Dewatering | Sludge Treatment System

    Sludge thickening and dewatering is two important stages in treating sludge. Thickening is the first step of sludge treatment in which the solids concentration is increased and the total sludge volume is correspondingly decreased, Thickening commonly produces sludge solids concentrations between 15% and 20%, LZZG Deep Cone Thickener results in maximum water recovery, maximum underflow

  • Thickener Ovivo

    When wastewater is treated, sludge is produced. Ovivo thickeners are designed to continuously produce as thick a sludge as possible. Powered by heavy-duty drives, designed to handle the specified torque for 20 years of continuous operation, the sludge is gently mixed by rotating rake arms.

  • Wastewater treatment Sludge treatment and disposal

    Wastewater treatment Wastewater treatment Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.

  • Sludge thickening and dewatering SUEZ Group

    Two processes can be used to thicken sludge: Static thickening, by gravitational settling Static thickening calls on conventional and innovative techniques, such as Drainis Turbo that eliminates the water at speeds higher than the conventional speeds, thereby optimising the downstream dewatering phase (reduction of the amount of equipment, energy and reagent consumption, etc.).

  • Gravity Sludge Thickening Tanks for slurry dewatering | LZZG

    Working principle . Deep cone thickener is a machine that based on gravity and sedimentation which makes solid-liquid separate from each other.The concentration of pulp waste water could be enhanced from 2%~ 15% to 60% ~ 70% by the machine, the clear water is overflow from the upper part of the thickener , so as to achieve the purpose of sewage purification and solid-liquid separation.

  • Sludge Thickening an overview | ScienceDirect Topics

    The primary objective of sludge thickening is to concentrate the solids, thus reducing the volume of sludge. Thickeners may increase the solids concentration by a factor of 2–5 and produce a clarified liquid effluent. Thickening is accomplished by either gravity or dissolved-air flotation. A gravity thickener is shown in Figure 10. The

    3. SLUDGE THICKENING. Thickening is provided to reduce the volume of sludge. Two basic types of thickeners work by gravity or flotation and use either continuous or batch processes. Gravity thickeners are essentially settling tanks with or without mechanical thickening devices (picket fence type). Plain settling tanks can produce

    SLUDGE DEWATERING ON DRYING BEDS * By C. H. Young District Engineer, Pennsylvania State Health Dept., Harrisburg When a well digested sludge is drawn to the drying beds it continues to gasify, and within several hours a considerable portion of the sludge solids will raise to the top and the dirty sludge water will remain be low.

    Sludge pumps, or slurry transfer pumps as they are otherwise known, are designed for transferring viscous fluids with high solid content. Typically, the sludge transfer pump design is a positive displacement pump to enable the handling of heavy, viscous and abrasive liquids including oil sludge, bio waste, sewage, mud and lime slurry.
