Optional lifting devices for either design offer additional operational flexibility EIMCO KCP HIGH RATE THICKENERS EIMCO K C P High Rate Thickeners are designed to maximize the flocculation efficiency, self dilution and settling rates EIMCO K C P High rate thickeners are designed to provide high underflow concentration with smaller diameter

CHAPTER 3 SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0 8 solids, can be thickened to a content

The purpose of this research is to design gravity thickener as appropriate equipment in conversion process of palm oil mill effluent POME to biogas at pilot scale in order to obtain high

hIGh RATE ThICKENER The DELKOR High Rate Thickener is a proven performer in a variety of different applications including minerals, industrial, chemical, water treatment and waste water industries The reliability and performance of DELKOR thickeners means that

High rate thickener ANDRITZ process engineering will determine the optimum percentage of feed solids for the specific application during laboratory or pilot plant test work The optimum percentage of feed solids will ensure proper flocculation and achievement of maximum fluxes t/m 2 /d

Another design variation, which improves the efficiency of the separation unit is the way the effluent enters the lamella clarifier Standard clarifier design has the effluent entering at the bottom of the inclined plates, colliding with the sludge sliding down the plates

Knowing how to size a thickener and determine the capacity required to handle a pre determined tonnage of a certain pulp, by overflowing a clear solution and obtaining the desired pulp density of thickener discharge, depends upon the settling rate of that particular pulp The settling rate of any pulp is easily determined by simple laboratory tests such as outlined below: Laboratory Test

xvEPA United States Environmental Protection Agency Biosolids Technology Fact Sheet Gravity Thickening DESCRIPTION Thickening is the process by which biosolids are condensed to produce a concentrated solids product and a relatively solids free supernatant

Dec 27, 2013 The DensaDeg® Clarifier/Thickener is a high rate solids contact clarifier which combines optimized flocculation, internal and external sludge recirculation, and plate settling in two conjoined

Separation is effected rapidly because of the system hydraulics, which can be in excess of twenty times the hydraulics of conventional thickeners As a result of the innovative design and associated hydraulic efficiency, the plant area for the HiFlo high rate thickener is greatly reduced, even making indoor installations practical

Inclined Plate Clarifier Design and Sizing Procedure The Impact of Settling Rate on Inclined Plate Clarifier Design You will note that the model #'s which represent the total cubic feet of media required changed from a high of 139 cubic feet to a low of 74 cubic feet That is a 46 change in the total size of the separator

High Rate Thickeners High rate thickeners are designed specifically to maximise the flocculation efficiency of flocculants They differ from conventional thickeners in feed well design, size and control Unlike conventional thickeners, high rate thickeners must use flocculants The basic design of a high rate thickener is below

This is normally achieved by using compression or high rate thickeners or a combination of thickeners and filter presses High Density Thickened Tailings HDTT are defined as tailings that have been significantly dewatered to a point where they will form a homogeneous non segregated mass when deposited from the end of a pipe Welch 2003

The High Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high rate machines Furthermore, they are normally positioned far away from
