The function of the High-Rate Thickener is to increase the density of a sludge stream. This is done by introducing the sludge into the settling tank and allowing the solids to settle. The clean water overflows for reuse or disposal. The settled solids are collected in the central cone of the decanter or clarifier and are disposed of as ...

Water balance of a high-density thickener in an iron ore concentrator plant. The most common problems in thickener operations include the presence of suspended solids in the recovered water and the density or percentage of solids of the thickener discharge outside the set targets. These problems are classified according to whether they are ...

PHOENIX HiFlo™ High Rate Thickeners clarify wash plant effluent water while thickening the slurry to 40-45% solids, greatly reducing the underflow slurry rate to the slurry pond. PHOENIX Thickeners use sedimentation technology to maximize the water recovery rate, providing clarified overflow water that can be recycled and reused in the process. …

The predominant types of gravity thickeners in industrial use are conventional thickeners, high-rate thickeners, and deep cone thickeners. Each type varies in design and operation to accommodate different sludge types and treatment capacities.

Water content of thickened sludge is very high (95%), so thickening is generally followed by chemical conditioning and dewatering [7]. Chemical conditioning is a very low-energy process that involves the addition of chemicals to encourage coagulation of solids and the release of absorbed water during dewatering.

AquaCycle™ is a high-rate thickener, recycling up to 90% of the process water for immediate re-use in the system. Learn more about the CDE AquaCycle.

The results show that thickening in terms of increasing the total solids content of sludge is possible with the modified hydrocyclone. In the field tests, a thickening factor (total solids content of thickened sludge related to feed sludge) of 1.31 (average) was reached for digested sludge.

WesTech. The AltaFlo™ ultra high-rate thickener is a rake-less thickener that provides mixing, flocculation and internal dilution followed by clarification and positive sludge collection and removal in a single tank. The principles of flocculation have been further adapted to a new design that will thicken slurries at an even higher rate than ...

Dissolved air flotation (DAF) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening.

High-Density Thickeners are similar to High-Rate Thickener but include additional features to increase underflow density and liquid recovery. These features include higher side walls and a steeper …

Thickening is the first step for reducing the sludge volume by removal of free sludge water. Thin sludge is concentrated to thick sludge. Thick sludge has a higher viscosity, but must still be pumpable. Sludge …

Hi-Rate Thickeners. The HI-RATE THICKENER is a MechProTech OEM product manufactured in-house. It has a structurally grated walkway across the top. Suspended from the walkway at the top of the tank is the drive assembly consisting of a gearbox driven by an electric motor and the hydraulic lifting system.

High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and shut down faster than conventional thickeners. However, due to their smaller size, high-rate thickeners require faster settling rates.

Excessively high sludge loading rates can result in disproportionate solids loss and poor thickening results. Conversely, a low loading rate would mean a longer retention time in the thickener, which can lead to the creation of anaerobic conditions that in turn may cause floating sludge and odor development.

High-Rate Thickeners separate liquids from solids using hindered settling. Rotating rake arms collect settled sludge and move it toward the center discharge cone. They use minimal amounts of polymers/chemicals to …

A clarifier will typically treat a low-density slurry of less than 5% weight per weight solids with a focus on producing a clear liquid with suspended solids of less than 100 parts per million (ppm). To achieve these high levels of clarity, the upcurrent flow (rise rate) needs to be low to prevent entrainment of fine particles.

The simple design provides for coagulation, flocculation, solids recirculation, clarification ...

Sludge can be thickened to 8-10% total solids. A pump then sends the sludge to the anaerobic digester. At the top of the basin is the scum collector and discharge. gravity thickener uses gravitational forces to separate water from sludge and is mainly used on primary sludge at plants still using this technology.

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.
