How a Thickener Works

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...

Improve Clarifier and Thickener Design and Operation

A design method for thickeners and clarifiers known as the batch flux curve technique was developed over 20 years ago, but still is not well-known in design and operating circles. An informal survey of major clarifier and thickener manufacturers found that none of the firms surveyed use this method for sizing and maximizing operating conditions.

Thickening - Resource Book

Flocculant is a chemical designed to increase particle-settling rates in a thickener. Flocculant causes a number of small individual particles to join together to form an agglomerate which settles much faster. Correct flocculation is the single most important factor in the operation of a high rate thickener.

The Science of Thickening Agents — The Culinary Pro

The goal of thickening a soup or sauce is to add viscosity, texture, and mouth-feel, helping the food to linger on the tongue and taste buds. Thin sauces have a more intense and direct flavor impact but will not have as lasting an effect on the palate. Adding a starch thickener helps the sauce cling to the tongue but is can block flavors so they may require more seasoning or flavoring.

A Critical Review of Thickener Design Methods t

The design method consists in measuring, in the labo­ ratory, the initial settling rate of a suspension with the concentration of the feed to the thickener and applying equation 6 to find the area S of the thickener. As we have already discussed, the concentration in the zone II of the thickener is not that of the feed

Factors That Influence the Design Process LEAFtv

A big part of the design process is the factor of cost. How much is it going to cost for you to produce and distribute your design? How much are people going to be willing to pay for the final product? These are all questions that, as a designer, you must ask yourself during the design process because it will influence the course of your design, as well as the final product. While you won’t ...

How to Improve the Thickening Effect of Thickener? -

The main factor affecting precipitation efficiency of thickener is the bottom inclination Angle of thickener. In order to discharge the sediment slurry at the central discharge port at the bottom of the pool, the thickener is designed to be tapered at the bottom, and the mud is continuously scraped to the discharge port at the center of the pool by a rake scraper.
