Chapter 1: Techniques - Jet-Wet Polymer Feeding: A Revolution in Water Treatment

This chapter explores the technical aspects of Jet-Wet polymer feeding, detailing how it operates and why it represents a significant advancement in water treatment practices.

1.1 What is Jet-Wet?

Jet-Wet is a revolutionary method of polymer feeding that employs a high-pressure jet of water to dissolve and disperse the polymer within a water treatment system. This process completely eliminates the need for separate dissolving tanks and agitators, offering a more streamlined and efficient solution compared to traditional methods.

1.2 How does Jet-Wet work?

The Jet-Wet system utilizes a high-pressure pump to force a stream of water through a specially designed nozzle. This high-pressure jet is directed onto the polymer, efficiently dissolving it into the water stream. The resulting mixture then flows into the treatment system, where it can be used for various applications, including coagulation, flocculation, and sedimentation.

1.3 Advantages of Jet-Wet:

• Improved Polymer Dissolution: The high-pressure jet ensures complete and rapid dissolution of the polymer, even in challenging conditions like low water temperatures or high polymer concentrations.
• Enhanced Polymer Dispersion: The forceful jet creates a uniform distribution of the dissolved polymer, leading to optimal mixing and coagulation in the treatment process.
• Simplified Operation: Jet-Wet systems are relatively easy to install and operate, requiring minimal maintenance and reducing the risk of operator error.
• Reduced Costs: Eliminating the need for separate dissolving tanks and agitators saves on both capital and operational costs.
• Enhanced Efficiency: The improved polymer dissolution and dispersion lead to greater treatment efficiency, requiring less polymer for the desired outcome.
