A flash mixer  is a high   speed mixing device used to rapidly mix chemicals with water in the initial stages of water treatment. The high-speed impeller ensures that the chemicals are evenly dispersed within the water to start the coagulation process.

 Key Functions:

• Rapid Mixing: Quickly disperses coagulants and other chemicals into the water to ensure uniform distribution.
• Initiates Treatment Process: Helps to initiate the chemical reactions necessary for subsequent treatment processes like flocculation.

 Advantages:

• Ensures efficient and even distribution of chemicals.
• Fast mixing to prevent localized overdosing.

Low maintenance due to durable construction, often made from stainless steel or corrosion   resistant materials.
