Frequently Asked Questions (FAQs)
1. How do your vessels address the corrosion challenges in water treatment applications?
Our vessels designed for water treatment incorporate several key features to manage corrosion and extend service life. We utilize specialized materials selected for their compatibility with treatment chemicals, implement enhanced corrosion allowances in critical areas, employ specialized coatings and linings with comprehensive quality verification, and conduct detailed chemical compatibility analysis for each application. For particularly aggressive environments, we employ additional design features such as sacrificial anodes, strategically placed corrosion-resistant alloy overlays, and specialized gasket materials. Our material selection process considers not only the primary process chemicals but also cleaning agents, disinfection protocols, and potential upset conditions to ensure long-term performance.
2. What materials are most suitable for drinking water pressure vessels?
Material selection depends on specific operating conditions, but common choices for potable water service include 316L stainless steel for most applications, epoxy-lined carbon steel for economical solutions, and duplex stainless steel for higher pressure or more aggressive water chemistry. All materials for drinking water contact are NSF/ANSI 61 certified or compliant with similar potable water standards. Each vessel is evaluated based on its specific water chemistry, temperature profile, pressure requirements, and treatment chemicals. For municipal applications, we coordinate with engineers to ensure compliance with local water authority material requirements and often provide additional documentation to support permitting processes.
3. How do you ensure compliance with both ASME and NSF/drinking water requirements?
For water treatment applications that require multiple standards compliance, we implement a comprehensive approach. Our engineering team carefully analyzes each vessel to determine the appropriate requirements, often consulting with NSF specialists during the design phase. For potable water applications, we ensure all materials, coatings, and manufacturing processes comply with NSF/ANSI 61 requirements while maintaining ASME code compliance. Our quality assurance system includes specialized checkpoints for drinking water applications, and we maintain qualification programs that ensure full compliance with all applicable requirements while meeting the unique needs of potable water systems.
4. What considerations are made for vessels supporting filtration and media retention?
Vessels designed for filtration incorporate several specialized features. These include optimized underdrain systems that maximize flow distribution while minimizing pressure drop, carefully designed lateral and header systems that ensure even media fluidization during backwashing, specialized internal components that prevent media migration, and nozzle designs that optimize both service and backwash flow patterns. For multi-media filters, we incorporate features that maintain media stratification, while for carbon and specialty media applications, we design for optimal contact time and minimal channeling. Our engineering team can provide hydraulic modeling and performance projections to support system design and optimization.
5. How do you address maintenance and accessibility needs for water treatment vessels?
We understand that regular maintenance is critical for water treatment systems. Our approach includes several strategies: strategically located and sized access ports that facilitate media replacement, internal designs that minimize areas where contaminants can accumulate, smooth interior finishes that facilitate cleaning, and removable components that allow for inspection and maintenance without complete system disassembly. For larger systems, we incorporate features such as davit arms for closure handling, platforms for safe access, and specialized quick-opening closures where appropriate. Our designs consider the specific maintenance protocols of the treatment system, including chemical cleaning procedures, media replacement schedules, and inspection requirements.
