Praestol and Zetag polymer for stable sludge dewatering in operation
Tested solution with documented effect in plants
Do you need Praestol and Zetag polymer where sludge does not drain effectively, or where the filtrate fluctuates in quality? Polymer becomes crucial in situations where the separation must function stably under load. At Dankalk K/S, as a lime plant, we work directly with polymer solutions that make sludge dewatering and process water run without unnecessary stops.
In practice, polymer functionality quickly becomes apparent. Wrong choice results in unstable flocs, high consumption and poor filtrate quality. With correctly selected Praestol or Zetag polymer you get stronger flocs, more uniform dry matter and cleaner filtrate on belt filters, decanters or disc filters.
5 advantages of our polymer
Choosing Praestol and Zetag polymer is about getting a solution that suits your plant and your load:
- Over 100 years of experience with raw materials and process chemistry in operation
- Tested polymer solutions with documented effect in sludge and process water
- Range with both Praestol and Zetag for different polymer properties
- Advice based on specific analysis of your sludge or process water
- Solutions that provide stable operation and reduce variation in dry matter
When the polymer matches the sludge type, dry matter and equipment, the dosage can be lowered, the separation improved and the filtrate becomes more uniform.

Polymer in operation where flocs, filtrate and solids must be controlled
Polymer is used to collect fine particles into larger flocs so that they can be separated from the water. This is the very core of polymer applications in both wastewater and industrial processes.
In operation, the right polymer can make sludge dewater faster, help filters and decanters run more stably, and provide a cleaner filtrate. This makes polymer functionality crucial when solids, load, and equipment must be aligned.
Polymer properties such as charge and molecular structure determine how flocs form and hold together. This is where the difference between products becomes apparent.
Praestol and Zetag in practice in your facility
Praestol and Zetag polymer are both used for separation, but they react differently in operation. Praestol is often used where stable floc structure is important for continuous operation. This is typically seen in biological sludge where uniformity is critical to equipment performance.
Zetag is often chosen when the load varies and there is a need for rapid flock formation and robust flocks that can withstand mechanical impact.
The choice between Praestol and Zetag depends on sludge type, dry matter, mechanical load and filtrate quality requirements. Therefore, the product should be evaluated together with dosage, solution and the equipment that will handle flocs in operation.
Polymer selected according to sludge, filtrate and equipment
Praestol and Zetag must be selected based on dry matter, particle structure, floc strength, filtrate quality, dosage and solution. At the same time, the polymer must be suitable for the equipment that handles sludge or process water in daily operation.
This makes it easier to achieve the correct dosage, keep the filtrate cleaner and make belt filters, decanters or disc filters work more uniformly.
Polymer in wastewater and industrial processes
Polymer applications are broad in both wastewater and industrial applications, including sedimentation, sludge dewatering and process water treatment, where challenges such as struvite , particles and varying solids can affect flow, filtrate and operation.
In plants with fluctuating loads, polymer becomes a crucial factor in maintaining capacity. The wrong polymer quickly results in poor separation, while the correct choice ensures that the equipment works as expected.
With the right Praestol or Zetag polymer, it becomes easier to handle changing loads, keep the filtrate cleaner and avoid unnecessarily high polymer consumption.
FAQ – Frequently asked questions about praestol polymer and zetag
What is polymer?
What is Praestol?
What is Zetag?
Is polymer plastic?
What is MS polymer?

What characterizes a polymer?
What are polymers used for?
Polymers are widely used in plastics, adhesives, sealants, textiles and process chemicals, while lime fillers are typically used as mineral fillers in other industrial materials. In wastewater and industrial plants, polymers are used primarily for flocculation, sludge dewatering and process water purification.
How is a polymer formed?
A polymer is formed by polymerization, where smaller molecules are linked together to form long chains. The structure, length and charge of the chains determine the properties of the polymer in practice.
