The MEMBRANE SYSTEM DESIGN QUESTIONNAIRE is an essential tool for planning and optimizing your reverse osmosis (RO) membrane setup. This manual page provides access to a free PDF designed to guide you through key considerations in designing an effective RO membrane system.

What this manual covers

• Assessing water source characteristics and quality requirements
• Selecting appropriate RO membrane configurations
• Designing system components for optimal performance
• Evaluating pretreatment and post-treatment needs

Common questions

How do I determine the right membrane size for my system?

Choosing the correct membrane size depends on your water volume needs and feedwater quality. This manual helps you evaluate these factors to match membrane capacity with your desired flow rate and rejection requirements.

What pretreatment steps are necessary before the RO membrane?

Proper pretreatment protects membranes from fouling and scaling. Common steps include filtration, pH adjustment, and chemical dosing, tailored to your specific water conditions as outlined in the design questionnaire.
