For industrial coating applications, several application processes are applicable including spray, dipping, curtain and brush. Let's review some of these application modes and explain how you can benefit from Coatex's rheology modifiers performance for your industrial coating applications.
The thickener in a lubricating grease is the component that sets grease apart from fluid lubricants. Thickeners are molecules, polymers, or particles that are partially soluble in lubricating fluid; they arrange themselves in such a way that they impart a semi-solid consistency to the grease.
Mar 06, 2018· Thickening tanks have slow-moving vertical paddles. Sludge flows into the thickening tank, and eventually, it removes excess water from the solids collecting at the bottom. A gravity thickener has a similar process to the tanks, but it has a sloped design so that solids collect at the base.
Beginners Guide to Thickeners; Beginners Guide to Thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes).
Aug 08, 2018· Working of a Thickener. Let us understand in detail about how thickeners work. To start with, it works on the principle of Gravity sedimentation and the most common construction of a thickener ...
Thickener All industrial manufacturers Videos. ISP Sludge Thickeners are used to thicken sludge from settling tanks in both municipal and ISP Sludge Thickeners are used to thicken sludge in municipal and industrial waste water ThickTech™ The ThickTech™ Rotary Drum Thickener (RDT) is the industry leading sludge thickener.
Our wide selection of industrial lubricants provide superior protection against wear, improving reliability and prolonging equipment life. Regardless of application, our industrial lubricants can help increase productivity and drive profitability. They can limit the possibility of …
The high time for thickeners was in the 60's when the metallurgical industries were booming and sizes of up to 150 m diameter were constructed. Such jumbo thickeners, when centrally driven, require for most demanding applications extra heavy duty drive heads some of which reach a continuous operating torque of 3.300.000 Nm.
Alibaba.com offers 540 industrial thickeners for mining products. About 43% of these are mining thickener, 10% are paper chemicals, and 10% are petroleum additives. A wide variety of industrial thickeners for mining options are available to you, such as coating auxiliary agents, electronics chemicals, and textile auxiliary agents.
At that time I was employed by Eimco in Salt Lake City, Utah and participated in a team that conducted test work checking the suitability of large diameter thickeners for both concentrate and tailings of the reprocessed ore. The picture on the right shows a 6 meter diameter wooden tank "Dorr" thickener installed back in 1908 in the Kennicott ...
Sep 07, 2000· Associative Thickeners in Waterborne Coatings - Generic Properties of Associative Thickeners for Waterborne Coatings One of the most important developments in the area of additives for waterborne coatings is the use of associative thickeners, and their use has so far been restricted to waterborne coatings only.
On the control of sludge level and under ow concentration in industrial thickeners Juan Pablo Segovia Fernando Concha Daniel Sbarbaro Department of Electrical Engineering, Universidad de Conc epcio n,
In oilfield applications xanthan gum provides excellent rheological control for water-based drilling, completion and work-over fluids in a wide range of brines. High viscosity at low concentrations and efficient solids transport in high viscosity/low shear conditions bring several benefits to drilling and oilfield applications, including
Thickeners: How they Operate. The most common solids-liquid (S/L) unit operation is thickening. A wide variety of thickeners are used including conventional, deep well, paste, high rate and clarifiers which is a thickener subclass used for removing solids from turbid or very low % solids waters.
A GUIDE TO UNDERSTANDING AND MIXING THICKENERS Rheology modifiers, commonly referred to as thickeners or viscosifiers, are ever-present in most products. The use of these additives cut across several process industries including food, pharmaceuticals, cosmetics …
Jan 26, 2015· Thickeners are designed to operate continuously with slurry/water consistently flowing into the centerwell with thickener underflow pumping balanced to maintain a mud bed in the thickener. Key to thickener operational efficiency is the solids must be able to settle 2-4 times faster than the nominal water up flow rate.
industrial, chemical, water treatment and waste water industries. The reliability and performance of DELKOR thickeners means that they are well represented throughout the world. With a wealth of experience and a large database of test work and commissioning, DELKOR can provide accurate estimates on sizing of a thickener for most applications.
A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in …
Thickeners and Hydrotropes Every country and every culture relates the quality of a product with its final appearance, mainly with its viscosity and transparency. In Latin America, high viscosity is directly related to high quality, whereas in Europe, low viscosity is closely related to being easy to dose.

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
A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the liquid are called scum.
Thickening Process The type of thickener considered in this work is a thickener with constant cross-sectional area operating in conventional mode, as shown in Figure 1. The feed containing a mixture of solid particulates and liquid is mixed with flocculent and fed continuously to the vessel at . The concentrated mixture is discharged at the bottom
Sep 13, 2013· gravity to the thickener and shall have the energy to aid mixing of flocculant solution with it. The feed well is sized adequately to take care of the venting of the entrapped air in the feed slurry.
A thickener/clarifier drive unit supplies the torque to rotate the rake arms through the thick sludge. The drive is usually made of cast iron because of its durability. Usage Examples Thickeners and clarifiers are often used in water and wastewater treatment plants to …
