What is the shelf life

Polymer Ferric Sulphate is a type of inorganic polymer coagulant that is commonly used in water treatment. It is typically used to remove impurities from industrial or municipal wastewater. Additionally, Polymer Ferric Sulphate is known to be effective in the treatment of papermaking, printing, dyeing, and other industries. This coagulant has been proven to be effective in removing suspended particles, colloids, and other organic contaminants from water sources. Its properties include high purity, fast flocculation, and easy sedimentation.

What is the shelf life of Polymer Ferric Sulphate?

The shelf life of Polymer Ferric Sulphate may vary, depending on how it is stored. Generally, it is recommended that this coagulant be stored in a cool and dry place, away from direct sunlight and heat sources. The recommended storage temperature is between 5°C to 30°C, and the storage humidity should be below 70%. If properly stored, Polymer Ferric Sulphate can have a shelf life of up to two years.

How is Polymer Ferric Sulphate used in water treatment?

Polymer Ferric Sulphate is used in water treatment by adding it to the water source. The coagulant works by destabilizing and neutralizing the particles and colloids present in the water, allowing them to form larger floc particles that can be more easily removed by sedimentation or filtration.

What are the advantages of using Polymer Ferric Sulphate in water treatment?

One of the main advantages of using Polymer Ferric Sulphate in water treatment is that it has a fast flocculation speed and a high sedimentation rate, which can greatly improve the efficiency of the treatment process. Additionally, this coagulant is known for its high purity and stability, which can help to reduce the amount of chemicals needed for water treatment.

What are the disadvantages of using Polymer Ferric Sulphate in water treatment?

Although Polymer Ferric Sulphate is generally considered to be a safe and effective coagulant, it may have some disadvantages when used in certain applications. For example, if overdosed, it may cause excessive coagulation or clogging in the filtration system. Additionally, it may not be effective in treating water with a high level of organic content or heavy metal ions.

In summary, Polymer Ferric Sulphate is a commonly used coagulant in water treatment, with properties that include high purity, fast flocculation, and easy sedimentation. Its shelf life can be up to two years if stored properly. Although it has many advantages, it may have some disadvantages in certain applications. When used correctly, it can be an effective tool for removing impurities from water sources.
