Q1: What is the primary mode of action of Lonza Lonzaserve 210 Fungicide?
A: Lonza Lonzaserve 210 functions as a broad-spectrum, preventive and curative fungicide, primarily inhibiting fungal cell wall synthesis and disrupting membrane integrity. Its active ingredient delivers reliable control against common saprophytic and spoilage fungi in industrial water systems and non-food-contact applications.
Q2: In which types of industrial systems is Lonzaserve 210 typically applied?
A: It is commonly used in recirculating cooling water systems, process water loops, paper mill white water systems, and other non-potable industrial water applications where microbial growth poses risks to system efficiency, material integrity, or product quality. It is not intended for food, beverage, or pharmaceutical manufacturing contact surfaces.
Q3: How is Lonzaserve 210 typically dosed and monitored in practice?
A: Dosage is adjusted based on system dynamics—including water temperature, nutrient load, and microbial challenge—and generally ranges from 0.1% to 2% by weight in the treatment solution. Continuous or intermittent feeding is recommended, with regular microbiological monitoring (e.g., heterotrophic plate counts) guiding dose optimization.
Q4: Is Lonzaserve 210 compatible with common water treatment additives?
A: Yes, it demonstrates good compatibility with many corrosion inhibitors, scale inhibitors, and other biocides used in industrial water treatment programs. However, compatibility testing under actual system conditions is recommended before full-scale integration, especially when co-dosing with oxidizing biocides or highly alkaline formulations.
Q5: What safety and handling considerations apply during storage and use?
A: Lonzaserve 210 should be stored in its original container in a cool, dry, well-ventilated area away from direct sunlight and incompatible materials. Personal protective equipment—including chemical-resistant gloves, safety goggles, and appropriate respiratory protection when handling concentrated product—is recommended. Always consult the Safety Data Sheet (SDS) for detailed handling, first-aid, and disposal guidance.
