Water & Wastewater Infrastructure Sealing Performance & Engineering
Modern municipal water distribution networks, desalination plants, and industrial wastewater treatment facilities require resilient elastomers that resist chloramine disinfectants, ozone treatment, and microbiological growth without leaching harmful contaminants.
Operating Challenges
- Chloramine & Ozone Degradation: Modern municipal water treatment uses chloramines and ozone which rapidly degrade ordinary Nitrile rubber.
- Potable Water Safety (No Leaching): Elastomers in drinking water circuits must not leach heavy metals, plasticizers, or impart taste or odor.
- Dynamic Valve Cycling: Large diameter butterfly valves undergo thousands of opening/closing cycles under abrasive silt and particulate loads.
