What is the difference between coagulant and flocculant?
Coagulation and flocculation are two separate processes, used in succession, to overcome the forces stabilising the suspended particles. While coagulation neutralises the charges on the particles, flocculation enables them to bind together, making them bigger, so that they can be more easily separated from the liquid.
What is polymer treatment?
In wastewater treatment processes, polymers are used to coagulate suspended solids and produce large curds of solid materials (floc).
What is a flocculant used for?
Used in a wide range of industries and applications, flocculants help to remove suspended solids from wastewater by aggregating contaminants into flakes or “flocs” that float to the surface of the water or settle at the bottom. They can also be used for lime softening, sludge thickening, and solids dehydration.
What is polymer dosing?
The elimination of liquid solids within wastewater treatment can be achieved through the use of liquid or powdered polymers; this is realised by the employment of polymer dosing and dosing systems.
Why are polymers important in wastewater treatment?
As you can tell, polymers play an important role in wastewater treatment. Besides separating solids from liquids, they also help thicken sludge and dewater contaminated material for easier handling and disposal. Removing the water content from a waste sludge can change the waste properties from liquid to solid waste.
What is a wastewater treatment polymer?
Wastewater treatment polymers usually come in either a dry granular form or a liquid form. The liquified polymers are known as emulsions and contain surfactants and emulsifying agents. These are roughly 1/3 equal parts and required to keep the flocculant portion in a readily available condition.
How does polymer dosing work?

How does Neo Waterfx 300 work?
On average, this tends to be about two (2) pounds of solids per 1,000 gallons of flow. To settle that quantity of solids, some amount of ferric- or aluminum compound is needed. However, more of these compounds are often added to also reduce phosphorus levels to the required targets. The addition of these coagulants generates additional solids and adds to the total amount of solids present in the water. Thus, using ferric- or aluminum-based compounds to settle solids and reduce phosphorus levels produces a cumulative effect on the quantity of sludge and adds to the sludge management problem.
Why do polymer sales continue?
Polymer sales people continue to sell polymer products into the wastewater treatment market because the market is so large and because those are the products they have available to sell. However, savvy plant operators increasingly understand that polymer products are treating the symptoms instead of the root causes of wastewater treatment problems. ...
What is wastewater polymer?
In wastewater treatment plants, polymers are primarily used to help manage the process of drying and consolidating sludge. Sludge created during the wastewater treatment process is typically a mixture of 5-10% waste material and 90-95% water. Moving and disposing of water-heavy sludge, often called “biosolids” or “solids” is usually one of the largest expenses for wastewater treatment plants along with labor and energy costs. That’s because even completely clean water weighs 8.3 pounds per gallon, and a 90-95% water sludge mixture is very expensive to move, process and dispose.
