Understanding Flocculation: The Basis of Rehydro-Floc

Flocculation is a crucial step in water treatment, utilizing chemicals called flocculants to bind small particles together, forming larger aggregates known as floc. These floc particles are then easily removed from the water through settling or filtration.

The Rehydro-Floc Process: A Step-by-Step Guide

1. Dosage and Mixing: The first step involves adding the correct dosage of Rehydro-Floc to the water source. This dosage is determined based on factors such as water quality, desired treatment goals, and application. Proper mixing is crucial for ensuring even distribution of the flocculant throughout the water.

2. Floc Formation: As the Rehydro-Floc solution is mixed into the water, the aluminum chlorohydrate hydrolyzes, releasing positively charged aluminum hydroxide ions. These ions attract negatively charged impurities, like suspended solids, organic matter, and microorganisms, forming "bridges" that bind them together.

3. Floc Settling: Once floc formation is complete, the larger aggregates settle to the bottom of the water due to their increased weight. This settling process is often aided by the use of sedimentation tanks or clarifiers.

4. Filtration: The final step involves removing the settled floc particles through filtration. This can be achieved using various filtration techniques, such as sand filtration, membrane filtration, or other appropriate methods.

Factors Influencing Flocculation Efficiency

• Water Quality: The effectiveness of Rehydro-Floc is influenced by water chemistry, including pH, temperature, and the presence of other chemicals or impurities.
• Dosage: Using the appropriate dosage of Rehydro-Floc is critical for optimal flocculation. Too little dosage may not be effective, while excessive dosage can lead to over-flocculation, hindering the settling process.
• Mixing: Proper mixing ensures even distribution of Rehydro-Floc throughout the water, promoting efficient floc formation.
• Residence Time: Adequate time is required for floc to form and settle properly.

Chapter 2: Models

Understanding the Chemistry Behind Rehydro-Floc

Rehydro-Floc's effectiveness stems from its unique chemical composition, aluminum chlorohydrate. When added to water, this compound undergoes hydrolysis, a process involving the reaction with water molecules. This hydrolysis results in the formation of positively charged aluminum hydroxide ions (Al(OH)n+). These ions play a crucial role in flocculation by attracting and bridging negatively charged impurities present in the water.

Rehydro-Floc and Water Chemistry: A Complex Interplay

The effectiveness of Rehydro-Floc is significantly influenced by the water's chemical composition. Factors like pH, alkalinity, and the presence of other dissolved salts affect the hydrolysis process and the formation of aluminum hydroxide.

• pH: Optimal flocculation typically occurs within a specific pH range. The pH influences the charge of the aluminum hydroxide ions and their ability to bind impurities.
• Alkalinity: The alkalinity of the water affects the availability of hydroxide ions, which are essential for hydrolysis and floc formation.
• Dissolved Salts: The presence of certain dissolved salts can interfere with the hydrolysis process, impacting the efficiency of Rehydro-Floc.

Modeling the Flocculation Process: Predicting Efficiency

Mathematical models can be used to simulate the flocculation process, predicting the effectiveness of Rehydro-Floc under different conditions. These models consider factors like water chemistry, dosage, and mixing, providing insights into the behavior of the flocculant.
