Hydrocells: A Powerful Tool for Water Treatment with Induced Air Flotation Separators
In the realm of environmental and water treatment, "Hydrocell" refers to a specialized technology employed for the separation of suspended solids from water. This method, often utilizing induced air flotation (IAF) separators manufactured by companies like USFilter/Whittier, relies on the principle of buoyancy to remove contaminants.
How Hydrocells Work: A Breakdown of Induced Air Flotation
IAF separators, also known as Hydrocells, work by introducing tiny air bubbles into the water stream. These bubbles attach themselves to the suspended solids, effectively decreasing the density of the contaminated particles. This buoyancy effect allows the solids to rise to the surface, where they can be collected and removed.
Key Features of USFilter/Whittier's Hydrocells:
- High Efficiency: IAF separators designed by USFilter/Whittier boast exceptional removal rates for a wide range of contaminants, including oils, greases, suspended solids, and biological matter.
- Versatility: Hydrocells find applications in diverse water treatment scenarios, from industrial wastewater to potable water treatment, and even municipal sewage treatment.
- Customization: USFilter/Whittier offers tailored Hydrocell designs to suit specific process requirements, ensuring optimal performance for each application.
- Minimal Footprint: Hydrocells are compact and can be easily integrated into existing water treatment facilities.
- Reduced Chemical Use: By relying on air injection rather than chemical flocculation, IAF separators minimize the use of chemicals, promoting environmental sustainability.
Benefits of Using Hydrocells:
- Improved Water Quality: Hydrocells effectively remove suspended solids, resulting in cleaner and more aesthetically pleasing water.
- Reduced Operational Costs: The high efficiency of IAF separators translates to lower operating expenses, as less energy and chemicals are required.

Hydrocell Exercise:
Problem: A wastewater treatment plant is experiencing difficulties removing oil and grease from its effluent. Currently, they rely on a chemical flocculation process, but it is not achieving the desired removal rate. They are considering implementing a Hydrocell system.
Task:
- Analyze the situation: Identify the key challenges faced by the wastewater treatment plant.
- Propose a solution: Explain how a Hydrocell system could address these challenges and improve the effluent quality.
- Highlight the advantages: Describe the specific benefits of using a Hydrocell in this scenario.
Exercice Correction
**1. Analysis:** The wastewater treatment plant is struggling to remove oil and grease from its effluent using a chemical flocculation process. This indicates that the current method is not effective enough. **2. Proposed Solution:** Implementing a Hydrocell system using Induced Air Flotation (IAF) technology could significantly improve the removal of oil and grease. The IAF process introduces tiny air bubbles that attach to the oil and grease particles, reducing their density and causing them to rise to the surface for collection. **3. Advantages:** * **Improved Removal Efficiency:** IAF technology is highly effective in removing oil and grease, potentially achieving a higher removal rate than the existing chemical flocculation process. * **Reduced Chemical Usage:** Hydrocells minimize the use of chemicals, leading to environmental benefits and reduced operating costs. * **Improved Effluent Quality:** The effective removal of oil and grease would significantly improve the effluent quality, ensuring compliance with environmental regulations and minimizing potential harm to receiving waters.
