Rehydro-Floc: A Powerful Tool for Water Treatment
Rehydro-Floc, a product by Reheis, Inc., is a type of aluminum chlorohydrate flocculant solution used extensively in environmental and water treatment. This solution plays a crucial role in removing impurities from water sources, ensuring clean and safe drinking water for communities.
What is flocculation?
Flocculation is a process that utilizes chemicals called flocculants to bind small particles together, forming larger aggregates called floc. These floc particles are then easily removed from the water by settling or filtration, resulting in cleaner water.
How Rehydro-Floc Works:
Rehydro-Floc is an effective flocculant due to its unique chemical properties. It consists of aluminum chlorohydrate, a compound that readily hydrolyzes in water, creating positively charged aluminum hydroxide ions. These positively charged ions attract negatively charged impurities in the water, such as suspended solids, organic matter, and bacteria.
The resulting aluminum hydroxide "bridges" these particles together, forming larger floc particles that are easily removed from the water.
Key Benefits of Rehydro-Floc:
- Effective removal of impurities: Rehydro-Floc efficiently removes a wide range of impurities from water, including suspended solids, turbidity, color, and microorganisms.

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
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.
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.
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.
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.
