Acrylic Polymers in Industrial Water Treatment
Acrylic Polymers are a range of chemicals used in various Industrial Water Treatment Applications. Depending on the structure and formulation of the Acrylic Polymer, they can help with particle dispersion, control of deposits and suit specific applications. They can be found in some cooling water systems, process water applications and industrial Water Treatment.
Depending on the formulation of the Acrylic Polymer will determine the function. The formulation of the Acrylic Polymer, the water chemistry, the plant running conditions and the aim, for the treatment are all important to understand. Acquiring knowledge on the Acrylic Polymer formulation, the water chemistry, the operation condition of the plant and the objective of the treatment enables the Acrylic Polymer formulation to achieve its results.
Knowing about various forms, usage and the elements that affect the selection of Acrylic Polymer will enable various industrial sectors to make a better decision.
What are Acrylic Polymers?
Acrylic Polymers are those materials which are developed from acrylic acid or related monomers. Depending on the formulation they can have different properties.
In Water Treatment there are many different formulations of Acrylic Polymers available to help with specific applications. Some Acrylic Polymers have been developed to help with particle dispersion whilst others can help with mineral deposits and scale control.
The performance of the Acrylic Polymer will depend on the structure.
Acrylic Polymers are not a one size fits all solution. There are various grades available with different properties. It is important to have a good understanding of the water system and what the treatment requirements are.
How do Acrylic Polymers work in Water Treatment?
Depending on the formulation and what is in the water, Acrylic Polymers will work in different ways. Often they will work by interacting with suspended or dissolved matter.
Some of the ways Acrylic Polymers can help with Water Treatment are:
Particle Dispersion
Some Acrylic Polymers can help keep particles dispersed in water. Depending on the type of particle and Acrylic Polymer chemistry they can prevent clumping.
This can help in systems where suspended matter can cause build up.
Scale Control
Mineral scaling can occur when salts in the water become concentrated and stick to equipment. Some Acrylic Polymer formulations can be added to help prevent scaling. The success of this depends on the salt type, water chemistry, temperature and plant running conditions.
Deposit Control
Deposits can cause build up of mineral particles, suspended matter and other substances. The right Acrylic Polymer can help with controlling deposits.
Supporting Treatment
If the right Acrylic Polymer is chosen it can help improve the chemical treatment. The success will depend on the filtration, chemical compatibility, dosing and monitoring.
Types of Acrylic Polymers in Industrial Applications
Acrylic Polymers are available in various chemical formulations. Depending on the monomers, weight and how they are made they will have different properties.
Some common types are:
Polyacrylic Acid
This polymer is an acid based polymer. It can be used in some Water Treatment applications to help with particle dispersion and mineral deposits.
The performance will depend on the weight, formulation and water conditions.
Acrylic Acid Copolymers
These polymers are created by mixing acrylic acid with monomers. This allows for the creation of polymers that can complete specific tasks.
Depending on the formulation they can be used for scale control, particle dispersion and industrial Water Treatment.
Acrylic Based Dispersant Polymers
Some Acrylic Polymer formulations have been created to help keep suspended particles dispersed. They can be useful in systems where particle build up and deposits need to be controlled.
Modified Acrylic Polymers
These polymers have been modified by changing the formulation to achieve the desired performance.
Depending on the formulation they can be used for specific industrial Water Treatment and process applications.
Key Applications for Acrylic Polymers
Acrylic Polymers are used in industries as the water quality requirements will vary between processes.
Cooling Water Treatment
Cooling water systems are constantly running and can cause changes in temperature, concentration and composition. This can cause issues with mineral scaling and deposits.
The right Acrylic Polymer formulations can be added to the cooling Water Treatment to help control some deposits and suspended particles.
They can be used in systems such as:
- Cooling towers
- Heat exchangers
- Industrial cooling circuits
- Recirculating cooling water systems are used to keep equipment cool in industrial applications.
The Acrylic Polymers will need to be chosen based on the water chemistry and cooling system running conditions.
Reverse Osmosis Water Treatment
Reverse osmosis systems require control of water quality to reduce the risk of membrane fouling and scaling. Some Acrylic Polymers can be used in membrane treatments if the chemistry is compatible. Not all Acrylic Polymers will be suitable.
The product selected will depend on membrane compatibility, feed water composition, pressure and scaling potential.
Industrial Process Water
Water is used in manufacturing industries for cooling, cleaning, processing and other applications. Depending on the source of the water there could be suspended matter, minerals and other impurities present.
The right Acrylic Polymers can help control selected particles and deposits within the Water Treatment.
Boiler Water Treatment
Boiler systems require control of the water chemistry. Deposits can cause issues with heat transfer.
Some Acrylic Polymer formulations may be used within boiler Water Treatment to help control some deposit forming materials.
The chemical selected will depend on the pressure in the boiler, water quality, running conditions and overall treatment.
Industrial Wastewater Treatment
Industrial wastewater can contain suspended matter, minerals and other substances. These will need to be treated. Certain Acrylic Polymers may help with selected stages of treatment where particle dispersion and deposit control is required. However, coagulation and flocculation may also be required to remove suspended matter.
The right function of the Acrylic Polymer will need to be identified.
Textile and Manufacturing Industries
Textile, paper, chemical and other manufacturing processes may use water that contains suspended matter and dissolved substances. Depending on the application, Acrylic Polymers may be considered for selected process Water Treatment. The suitability will depend on the nature of the process and water quality.
Benefits of using Acrylic Polymers
Depending on the chemical composition and application, Acrylic Polymers can provide various benefits.
Some benefits include:
- Particle Dispersion – Some formulations can help keep particles evenly dispersed in water.
- Scale Control – Selected Acrylic Polymers can help with programmes to control mineral scaling.
- Deposit Control – The right formulation can help with controlling deposit forming materials.
- Flexibility – Different Acrylic Polymer formulations can be created for industrial applications.
- Treatment – Acrylic Polymers can be used as part of a Water Treatment programme.
- Consistency – Choosing the right Acrylic Polymer and dosing can help provide consistency in treatment.
The actual performance will depend on the grade of polymer, water composition, dosage and running conditions.
Acrylic Polymers vs Other Water Treatment Polymers
Water Treatment polymers are created to provide different functions. Acrylic Polymers should not be seen as a universal solution.
| Polymer Type | Application |
| Acrylic Polymers | Selected scale control and particle dispersion |
| Epi-DMA Polymers | Coagulation and selected wastewater treatment |
| DCDA Polymers | Colour removal and coagulation in selected wastewater applications. |
| Dispersant Polymers | Keep particles dispersed and control selected deposits. |
| Flocculant Polymers | Help to create larger flocs from suspended particles. |
The exact function will depend on the formulation. The chemical should be chosen based on the treatment requirements rather than polymer type.
