The Role of Polymer in Wastewater Treatment
Polymers play a crucial role in wastewater treatment. They are used as a chemical reagent to bind small solid particles into larger ones, which makes the separation of solids and free water more efficient.
These chemicals are vital in the coagulation and flocculation stages of wastewater treatment:
- Coagulation is the first step, where polymers neutralize the charges on particles suspended in the water. These particles, often tiny and dispersed, carry electrical charges that separate them. Polymers neutralize these charges, allowing the particles to come together and form small clumps.
- Flocculation follows coagulation. In this stage, polymers act as binding agents that combine the small clumps formed during coagulation into larger, more easily separable flocs. These larger flocs settle more quickly and are easier to remove from the water.
This two-step process of coagulation and flocculation significantly improves solid-liquid separation and results in a more concentrated sludge that’s easier to handle, process, and dispose of in the dewatering stage of the wastewater treatment process.
Types of Polymers in Wastewater Treatment
Two primary types of polymers are used in wastewater treatment: anionic and cationic.
- Anionic Polymers have a negative charge and are used to treat water with positively charged particles. They are ideal for inorganic solids like clay, silt, and soil from waste solutions. This is particularly useful for wastewater generated by mining projects or heavy industries.
- Cationic Polymers have a positive charge and are effective at removing organic solids from wastewater, such as human waste, animal matter, and plant material. They are commonly used in municipal wastewater treatment plants and are also utilized in agricultural and food processing facilities.
Polymers can have varying charges and structures (branched, linear, cross-linked) and are available in various forms, including dry powder and liquid emulsions. There are hundreds of different types of polymers and polymer manufacturers to choose from. The choice of polymer type and form depends on the specific characteristics of the wastewater and the desired treatment outcomes.
The High Cost of Polymer in Wastewater Treatment
Polymers are essential for efficient liquid-solid separation, although water treatment plants are often looking for ways to reduce polymer use because it accounts for the majority of centrifuge operational costs.
Beyond the cost of the polymer itself, plants must also consider the expenses related to shipping, storage, and handling. Additionally, polymers are petroleum products, and their cost often fluctuates year to year, making it challenging to predict and manage overall polymer costs.
Fortunately, adding a sludge thickening system to your process can significantly help mitigate overall polymer use and cost. Sludge thickening reduces the biosolid’s water content, resulting in a more concentrated sludge that is easier to handle in the dewatering stage.

How the Centrisys/CNP THK Sludge Thickener Can Help Lower Polymer Costs
The Centrisys/CNP THK Series Sludge Thickener is a centrifuge explicitly designed for sludge thickening. The system uses high rotational speeds and precise patented engineering to create optimal conditions for solid-liquid separation, resulting in a good capture rate and precise control of cake solids.
Depending on the desired level of performance, the THK sludge thickener can operate without polymer. If a polymer is used in the process, the THK features multiple injection points in the feed pipe and internally within the centrifuge. This targeted application ensures polymer is used efficiently and directly where needed most, enhancing flocculation and improving the overall separation process.
The Centrisys/CNP THK Series Sludge Thickener is the ideal solution for water treatment plants looking to optimize their centrifuge operations and reduce overall polymer use and cost. Learn more about the THK series here!
Customized Sludge Sample Analysis and THK Pilot Testing by Centrisys/CNP
At Centrisys/CNP, we understand wastewater treatment is an art, not a science. A system or process that works for one plant’s operation may not work for yours, which is why our expert team will take your sludge sample in our process lab and analyze it to give you an idea of its thickening performance (cake total solids, capture rate) with polymer and without polymer.
Using the sample analysis as a guide, the process engineering team then provides an on-site pilot test using a THK sludge thickener, ensuring accurate scaling at your facility. The result is a customized THK installation and polymer solution that maximizes efficiency while minimizing polymer use and overall costs.
