Embodiment Construction

[0024] Any coarse or larger debris is stripped (removed) from the sludge by ancillary upstream techniques, along with sand and other materials that do not require dewatering, before reaching the apparatus of the present invention. The suspended solids retained in the influent sludge are preferably suitably conditioned by the introduction of coagulants and / or flocculants which cause the solids in the sludge to agglomerate to form "floes" in a conventional manner. By means of the present invention, the formation of flocs in the sludge allows proper and maximum dewatering. The apparatus, process and method of the present invention are specifically designed to accept an influent consisting primarily of floc and water (but may include other solids). Typically in industry, the term "influent" is used to refer to wastewater flowing into a treatment plant. However, the present invention is applicable to the treatment of a wide variety of materials having substantial water content and...

Abstract

A system is provided for the dynamic dewatering of any of a variety of sludges, slurries, or water waters. A stream of material is treated in a series of distinct operations to release free water, draw off additional water through vacuum, and compress the resultant dewatered solids to result in a substantially dewatered material. One or more open cells are used in vacuum dewatering in continuous dynamic operation. The system may be integrated into a packaged unit that may be installed at a operation site, and maybe operated with multiple like units to increase treatment flowrates.

Description

technical field [0001] The present invention relates to the dewatering of material streams. The present invention comprises an apparatus and an improved method for removing liquid (water) from sludge, slurry or suspension (commonly referred to collectively by the term "sludge"). Considering the specific apparatus, process and method of dewatering, sludge is also referred to herein as influent. Background technique [0002] In many industries, sludge is a by-product of industrial operations and processes. It is often beneficial to separate the liquid and solid components of sludge for reuse, better management or disposal of recovered material (solid or liquid). [0003] It is highly desirable in most industries to be able to dewater sludge economically, efficiently and effectively at high process rates. The dewatered solids need to be dried sufficiently to be able to be managed and meet landfill regulations or be beneficially reused. The effluent (discharged water) often ...
