Is a High-Density Thickener Suitable for Your Application? Know Here

Using a high-density thickener is a common process in many industrial applications. They are used to separate solids and liquids. They have a higher solid concentration compared to conventional thickeners. They have steep walls and use optimised feedwell geometry to compress solids with ease. They are more effective than conventional ones. 

The result?

• Thicker underflow discharge
• Enhanced water recovery
• Lower costs of downstream processing
• Reduced equipment footprint

These benefits are crucial, but they are not appropriate for every industrial application. This blog will discuss whether high-grade thickeners are appropriate for your industry.

When Should You Consider a High-Density Thickener?

The following scenarios will clarify when you should consider using a high-density thickener. 

1. You Need a Higher Solids Concentration in the Underflow

If you require a thick, high-density underflow to feed your filters, paste thickeners, or for tailings disposal, a high-density thickener is a suitable option. It is designed to accommodate high solids loads and will provide concentrated discharge without compromising stability.

Example:

In a tailings management system, the goal is often to minimise water loss. A high-density thickener can recover more water while sending denser slurry downstream — reducing the need for large storage facilities.

2. You Are Limited by Space

Plant layouts often face space constraints. A conventional thickener with a large diameter might not fit within the available footprint.

High-density thickeners are compact by design. Their steep side walls and efficient settling zones mean they can achieve the same — or better — results in a smaller area.

If your plant expansion is limited by available space, this type of thickener could be a practical solution.

3. Water Recovery Is a Top Priority

In locations where shortages of water affect operations, optimising water reuse becomes a priority. High-density thickeners are very effective at recovering water from slurry before it is ultimately disposed of. With a clear overflow, high-density thickeners effectively reduce overall water use in the process and improve the management of water. For mines and aggregate plants branded in arid areas, a reduction in water use like this alone can justify the capital costs.

4. You are trying to lower energy and operating costs. 

While high-density thickeners can have a high initial acquisition cost (in a capital cost perspective), they represent long-term savings. High-density thickeners use less energy for pumping liquid and subsequently dewatering because they produce a denser underflow. Also, using less water for the entire process will lead to a lower equipment capital cost, which leads to a lower maintenance and operating cost as well. 

For many operations, this can be a practical upgrade from the conventional process to a more energy-efficient and sustainable process. In a time when both of these things are becoming non-negotiable. Cornstarch is a common thickener used in situations where low energy and operating costs are required.

5. Your Process Involves Fine or Slow-Settling Particles

A high-density thickener should be used for ultra-fine particles so you have the ability to enhance the flocculation and settling characteristics. 

This allows you to perform reliably even with difficult feed materials and process and throughput stability.

When Should You Not Choose a High-Density Thickener?

Do not choose a high-density thickener if:

• Your process involves coarse, fast-settling solids that dewater easily.
   
• Space and water constraints are not significant concerns.
   
• You already achieve the desired solids concentration with a conventional thickener.

How to Choose the Right Thickener for Your Operation?

Before deciding, evaluate your process objectives carefully:

• What solids concentration do you need in the underflow?
   
• How important is water recovery to your operation?
   
• Do you have enough space for a conventional thickener?
   
• Are your materials fine-grained or coarse?
   

A detailed process analysis and pilot testing can help determine the ideal thickener type and configuration for your specific plant conditions.

Conclusion

In the case that an operator is working towards improved water recovery and is producing a thicker solids output, a high-density thickener may be the best tech option available. That being said, the appropriate technology for you depends on your process parameters, material properties, and goals. 

If you have a space limitation, if your site makes water handling difficult, if you desire a denser discharge for your tailings, or if you desire the denser discharge for a pre-filtering, a high-density thickener may be the best option. Yet, if you don't have as complex a process, it is possible that the conventional thickener options are still the best economic option available.

FAQs:

Q1.Explain the distinction between a high-rate thickener and a high-density thickener.

Yes. A high-density thickener is identical to a high-rate thickener except for the additional features a high-density thickener has, which leads to more liquid recovery.

Q2. How many varieties of thickeners are there? Name them.

There are two varieties of thickeners – starch thickeners and gum thickeners.

Q3. What is the most usual thickener?

The most usual thickener used in industrial applications is cornstarch.

Q4. Where can I buy the best quality high-density thickeners?
