# Industrial Specification: Reverse Osmosis Unit

## 1. Technical Definition
A pressure-driven membrane separation unit that removes dissolved solids, ions, and contaminants from water by forcing it through a semi-permeable membrane.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-60 bar (217-870 psi)**. Failure boundary: **Membrane burst pressure at 83 bar (1204 psi) for polyamide composite membranes**, Mechanism: **Polymer chain scission and membrane delamination due to exceeding tensile strength of 70 MPa for polyamide active layer under sustained pressure differential**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Calcium sulfate scaling precipitation when Langelier Saturation Index exceeds +0.5 | 8 | Membrane flux decline to below 10 LMH (liters per square meter per hour) at constant pressure | Antiscalant injection at 3-5 ppm concentration with threshold inhibition chemistry |
| Chlorine oxidation exposure above 0.1 ppm concentration for polyamide membranes | 8 | Membrane salt rejection degradation from 99.7% to below 95% | Sodium bisulfite dechlorination to maintain ORP below 200 mV |
