# Membrane System Designer Skill

## Purpose

The Membrane System Designer Skill designs membrane separation systems including reverse osmosis, ultrafiltration, nanofiltration, and gas separation applications.

## Capabilities

- Membrane selection and sizing
- Module configuration design
- Permeate flux calculations
- Fouling prediction and mitigation
- Cleaning protocol design
- Multi-stage system design
- Recovery and rejection optimization
- Energy consumption analysis

## Usage Guidelines

### When to Use
