b) Cationic
4. What is the main purpose of the controlled environment provided by a detention tank?
a) To prevent the polymer and extender from reacting. b) To allow for proper mixing and activation of the extender. c) To increase the flow rate of water through the treatment process. d) To separate the treated water from the sludge.
b) To allow for proper mixing and activation of the extender.
5. Why are detention tanks important in reducing chemical usage?
a) They allow for faster treatment times, reducing the amount of chemicals needed. b) They reduce the volume of water needing treatment, thus reducing chemical use. c) They optimize the effectiveness of the polymers and extenders, reducing the amount needed. d) They filter out impurities, reducing the need for additional chemicals.
c) They optimize the effectiveness of the polymers and extenders, reducing the amount needed.
Scenario: A water treatment plant is experiencing difficulties removing suspended solids from the incoming water. They currently use anionic polymers but are considering switching to cationic polymers. However, they are unsure if they need to invest in a detention tank for optimal results.
Task:
**1. Why cationic polymers might require a detention tank:** Cationic polymers work best with anionic extenders. These extenders require proper mixing and reaction time to activate fully. A detention tank provides the controlled environment necessary for these processes, ensuring optimal performance of the cationic polymers and the extenders. **2. Reasons for a detention tank regardless of polymer type:** * **Improved flocculation:** The detention tank provides a longer residence time for the polymers and extenders to work, resulting in larger and heavier flocs. This facilitates more efficient sedimentation and removal of suspended solids. * **Reduced chemical dosage:** The detention tank allows for better optimization of the polymer and extender dosage, potentially leading to reduced chemical usage and cost savings. **3. Testing the effectiveness of a detention tank:** A pilot-scale detention tank could be constructed and tested in parallel with the existing treatment process. The treated water from both systems can be compared for suspended solid content, turbidity, and chemical dosage. This would allow for a direct evaluation of the detention tank's effectiveness before committing to a full-scale investment.
