Polymer and Flocculant FAQs

When do you use cationic, anionic or non ionic polymers?

Cationic and anionic polymers are both used in water and wastewater treatment depending on the charge of the suspended particles. Cationic polymers, which are positively charged, are used when the particles in the water are negatively charged, making them suitable for treating municipal and industrial wastewater containing organic matter, such as sewage sludge and effluents from food processing and pulp and paper manufacturing. Conversely, anionic polymers, which are negatively charged, are used when the particles in the water are positively charged, making them ideal for treating mineral and inorganic particles found in mining operations and certain industrial wastewater treatments. The choice between cationic and anionic polymers is primarily based on the particle charge, but factors such as the water’s pH and any other specific treatment process prior such as coagulation also play important roles.

How much polymer is needed to dewater sludge?

The amount of polymer needed for sludge dewatering ranges from 1 to 10 kilograms per ton of dry solids, depending on factors such as the type of sludge, its concentration, the specific polymer used, and the dewatering equipment employed such as screw presses, belt presses, chamber filter presses or centrifuges. Biological sludge usually requires higher polymer doses due to its higher organic content and water retention properties, whereas chemical sludge often needs less polymer. To determine the optimal polymer and dosage, it is ideal to conduct bench-scale tests, or even pilot-scale trials to tailor the treatment to specific sludge characteristics and operational conditions, however, Hydroflux Utilities has extensive expertise in sludge flocculation and dewatering and can usually select a suitable polymer based on previous successes.

Is a higher molecular weight polymer better?

The choice between high and low molecular weight polymers in water and wastewater treatment depends on the application and desired outcomes. High molecular weight polymers are generally better for flocculation due to their longer chains, which form larger and more robust flocs, enhancing settling rates and dewaterability. However, they are more shear-sensitive and can break down under high agitation. Low molecular weight polymers, being less shear-sensitive, are more effective in high-turbulence conditions and form smaller, more compact flocs, beneficial in some filtration and clarification processes. The decision should consider the specific treatment needs, including contaminant nature, water or sludge characteristics, dewatering equipment, and operational conditions.

Does the chemistry applied to my wastewater treatment plant effect the amount of sludge generated?

Yes it does! The type and dosage of chemicals, such as coagulants and flocculants, influence the characteristics of the sludge, including its volume, density, and dewaterability. Effective chemical treatment can enhance the aggregation of suspended particles, resulting in a more compact and settleable or floatable sludge depending on whether you are using clarification or flotation technology for solids removal, which is easier to handle and dewater. Conversely, improper chemical dosing or selection can lead to excessive sludge production or poor sludge quality, complicating its management and disposal. Optimising the wastewater treatment chemical treatment program is crucial for optimum treatment and efficient sludge handling and minimising overall operational costs.

Which is better, a liquid emulsion or a powdered polymer?

The choice between emulsion and powder polymers for wastewater treatment depends on the specific application and operational requirements. Emulsion polymers are typically easier to handle and dose, using relatively inexpensive blending equipment and are ready to use within a few minutes of solution preparation. Emulsion polymers are ideal for small to medium applications. On the other hand, powder polymers offer advantages in terms of storage, shelf life, and transport, as they are more stable and less prone to degradation than emulsions although they do take between 30 -90 minutes dilute and activate. Powder polymers are usually more cost-effective in large-scale operations where the cost of the blending and dosing equipment is high to ensure proper activation and performance. Ultimately, the choice between emulsion and powder polymers should consider factors such as handling logistics, cost of the polymer, cost of the blending and dosing plant and the specific characteristics of the wastewater being treated.
