Vostrip: A Powerful Tool for Water Treatment
What is Vostrip?
Vostrip, or Volatile Organic Compound (VOC) stripping, is a crucial process in environmental and water treatment, designed to remove volatile organic compounds from water. These VOCs, often harmful pollutants, can include chemicals like benzene, toluene, and trichloroethylene, posing significant threats to human health and the environment.
How Vostrip Works:
The Vostrip process utilizes a simple principle: mass transfer. By passing contaminated water through an air stripping tower, VOCs are transferred from the liquid phase to the gas phase.
The Key Components of a Vostrip System:
- Air Stripping Tower: This tower serves as the main vessel where water and air come into contact. The tower design can vary depending on the specific application and contaminant, with common features including packing media and air distribution systems.
- Packing Media: These materials, often made of plastic or ceramic, provide a large surface area for contact between water and air, enhancing the transfer of VOCs.
- Air Blower: This device delivers a constant flow of air to the tower, facilitating the stripping process.
- Water Inlet and Outlet: These points allow for the continuous flow of contaminated water into the tower and the discharge of treated water.
- Air Exhaust System: This system ensures safe removal of the air containing the stripped VOCs, often incorporating scrubbers or other treatment systems to minimize environmental impact.

Vostrip Exercise
Scenario: A factory discharges wastewater containing benzene, a volatile organic compound, into a nearby river. They need to implement a Vostrip system to reduce benzene levels in the wastewater before it is released.
Task:
- Identify the key components of the Vostrip system needed for this application.
- Explain how each component contributes to removing benzene from the wastewater.
- Suggest two additional features that could be incorporated into the system to enhance its efficiency and environmental impact.
Exercise Correction
**1. Key Components:** * **Air Stripping Tower:** This tower will be the main vessel where wastewater and air come into contact. The tower's design should be tailored to the flow rate and benzene concentration. * **Packing Media:** Suitable packing media, such as plastic or ceramic materials, should be selected to maximize contact surface area between the wastewater and air, promoting efficient benzene transfer. * **Air Blower:** This component will provide a continuous supply of air to the tower, driving the stripping process. * **Water Inlet and Outlet:** These will allow for the continuous flow of contaminated wastewater into the tower and the discharge of treated wastewater. * **Air Exhaust System:** This system should effectively remove the air containing the stripped benzene, possibly employing a scrubber or other treatment methods to minimize environmental impact. **2. Component Contributions:** * **Air Stripping Tower:** Provides the necessary space and conditions for the transfer of benzene from the water to the air. * **Packing Media:** Increases the contact surface area between water and air, enhancing the mass transfer of benzene. * **Air Blower:** Delivers a constant flow of air, ensuring sufficient contact time and driving the benzene stripping process. * **Water Inlet and Outlet:** Allow for continuous flow of wastewater and treated water, ensuring ongoing treatment. * **Air Exhaust System:** Safely removes the contaminated air containing the benzene, reducing environmental risks. **3. Additional Features:** * **Monitoring System:** A monitoring system could be installed to track the benzene concentration in both the incoming and outgoing water streams, allowing for real-time performance assessment and adjustments to the Vostrip system. * **Activated Carbon Filter:** Adding an activated carbon filter to the air exhaust system could further reduce the concentration of benzene in the air before it is released, minimizing environmental impact.
