Exercise:
Scenario: You manage a water treatment facility that utilizes a reverse osmosis system. The facility has been experiencing a decline in water production, and you suspect membrane fouling.
Task:
- Identify the possible types of fouling based on your knowledge of KochKleen cleaning chemicals.
- Propose a cleaning strategy using specific KochKleen product series (e.g., KochKleen 400 Series, KochKleen 500 Series).
- Explain the rationale behind your cleaning strategy, considering the specific types of fouling you identified.
Exercise Correction
Here's an example of a possible solution: **1. Possible Types of Fouling:** * **Organic fouling:** This is common in water treatment facilities and can be caused by natural organic matter or industrial byproducts. * **Inorganic scaling:** This is often caused by minerals like calcium carbonate, which can form hard deposits on the membranes. **2. Cleaning Strategy:** * **KochKleen 500 Series (alkaline solutions):** To remove organic fouling. * **KochKleen 400 Series (acidic solutions):** To remove calcium carbonate scale. * **KochKleen 600 Series (biocides):** To sanitize the RO system and prevent bacterial growth. **3. Rationale:** * The combination of alkaline and acidic cleaning agents addresses the most likely types of fouling in this scenario. * Sanitizing the system with biocides ensures that any remaining organic material or bacteria are eliminated, preventing future fouling. **Important Note:** This is just an example solution. The specific cleaning strategy should be tailored based on the actual water quality and the results of a thorough membrane inspection. Koch Membrane Systems' technical support can provide valuable guidance for specific situations.
