British Columbia, Canada, December 28, 2020-Dry polymers have been used in water purification and sludge water treatment for decades. The separation of wastewater largely depends on floatation and polymers help to reduce the burden of the solids being separated. In addition, the dosage of chemicals used is also reduced significantly. If you are looking to use dry polymers for wastewater treatment, here are the merits and demerits of this products.

Advantages

Storage and Cold Weather are No Longer a Problem

With dry polymers, you will not have any problems storing them or having challenges during cold weather. This is because they do not freeze like the liquid polymers. With liquid polymers, you can thaw out and use them after one freeze. However, precautions must be take including no-freeze shipping and this increases the overall cost of liquid polymers. This is something you will never deal with when using dry polymers.

No Room for Errors in your Mix Calculations

Dry polymers come in 100% solid. However, liquid polymers are 45 to 55% solids and they need calculating the party of weight to be mixed with water. As a result, they are more complicated to deal with, especially for people who lack technical or mathematical knowledge. With dry polymers, you can eliminate manual calculations. This means that you will have an easy time measuring your dry polymers and using them and this lowers the risk of errors.

Saves Time When Weighing Out Ingredients

Dry polymers include shrinkage reducing admixture and defoamer. As a result you will spend less time weighing the ingredients. You can be confident that there are no variations in the quantity of entrapped air that can affect flexural strength. All you need to do is just weigh your dry polymer and add it to the wastewater treatment as recommended by the manufacturer. You will spend less time than when you use other products.

Disadvantages

Dry polymers need further manufacturing before use

Polymers are the trickiest chemicals to properly manage on a waste water treatment plant. This is because they are supplied as products that require further manufacturing before use. For instance, powder or dry polymers must be added to water or wetted before they are used and this process may take up to one hour.

Technical Knowledge is a Must

To correctly use dry polymers, scientific knowledge is a must. To properly hydrate your dry polymer before yes, you need a high understanding of the physio-chemical processes that are taking place. This will ensure that you choose the right and most suitable equipment to assist in the initial wetting of the polymer before hydration to allow uncoiling to occur. With technical knowledge, you can avoid polymer clumping, which is irreversible and can cause wastage.

Dry polymers are extensively used in the wastewater and industrial water treatment plants. Even with the right water treatment plant, choosing the right polymer is just half the battle. This is because there are several crucial operational parameters that must be well managed. You must be confident that your polymer make-up systems is in perfect condition and provides premium quality polymer solution.
