Lethal Service Pressure Vessels for Water and Wastewater Treatment | Roben Manufacturing
Lethal Service Vessels for the Water and Wastewater Treatment Industry
Water and wastewater treatment facilities use chlorine, chlorine dioxide, ammonia, and other lethal substances to disinfect drinking water and treat wastewater. These essential public health operations handle large quantities of toxic chemicals, often in facilities adjacent to populated areas. Pressure vessels containing these disinfection chemicals must provide fail-safe containment while meeting the continuous operation demands of municipal water systems.
Industry-Specific Requirements
Water treatment lethal service vessels must operate reliably around the clock while containing chemicals essential for public health but deadly if released. Chlorine service requires materials resistant to both wet and dry chlorine attack. Chlorine dioxide generation systems handle this potent oxidizer that cannot be stored. Ammonia systems for chloramine disinfection face different corrosion challenges. Roben Manufacturing provides vessels meeting both ASME lethal service requirements and AWWA standards for water treatment equipment.
Lethal Substances Handled
Water and Wastewater Treatment lethal service vessels contain:
• Chlorine gas (Cl2)
• Chlorine dioxide (ClO2)
• Ammonia (NH3)
• Sodium hypochlorite (concentrated)
• Sulfur dioxide (SO2)
• Ozone (O3)
• Hydrofluosilicic acid
• Ferric chloride (concentrated)

Frequently Asked Questions
What defines lethal service under ASME Code?
ASME Code defines lethal service as vessels containing poisonous gases or liquids of such a nature that a very small amount mixed or unmixed with air is dangerous to life when inhaled. This designation triggers mandatory additional requirements including 100% radiographic examination of welds, post-weld heat treatment, and enhanced documentation.
What materials does Roben recommend for water and wastewater treatment lethal service?
Material selection depends on the specific substances handled, process conditions, and corrosion environment. Our engineering team provides material recommendations based on your specific application, considering both technical performance and code compliance requirements. We work with stainless steels, nickel alloys, titanium, zirconium, and specialty alloys as appropriate.
How does Roben support our PSM/RMP compliance?
Roben’s comprehensive quality documentation directly supports Process Safety Management and Risk Management Program mechanical integrity requirements. We provide baseline data for inspection programs, maintain fabrication records, and can format documentation packages for your PSM files. Our engineering team is available to support mechanical integrity reviews and audits.
