# Industrial Specification: Drainage System

## 1. Technical Definition
A system designed to collect and remove wastewater, chemical residues, and sanitization fluids from the Chemical Sanitization Chamber.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 bar differential pressure**. Failure boundary: **4.2 bar differential pressure or 85°C fluid temperature**, Mechanism: **Material yield strength exceeded at 4.2 bar (316L stainless steel, 205 MPa yield) or polymer seal degradation above 85°C (EPDM rubber, Tg 45°C)**.

### 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 |
| :--- | :--- | :--- | :--- |
| Particulate accumulation exceeding 150 μm diameter at pump impeller | 8 | Cavitation-induced impeller erosion and flow reduction to 40% rated capacity | Install 100 μm duplex basket strainer with differential pressure monitoring (0.2 bar alarm setpoint) |
| Chemical concentration gradient causing pH below 2.0 or above 12.0 | 8 | Intergranular corrosion at weld seams and seal material swelling exceeding 15% volume | Implement real-time pH monitoring with automated neutralization injection at pH 3.0/11.0 thresholds |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are recommended for drainage systems in chemical sanitization chambers?
**A**: Our drainage systems use corrosion-resistant materials like stainless steel (304 or 316L), chemical-resistant PVC or CPVC, and polypropylene to withstand harsh chemicals and ensure long-term durability.

### Q: How does the drainage system handle chemical residues and sanitization fluids?
**A**: The system features a specialized drain pipe network with chemical-resistant components and P-traps designed to safely collect and remove aggressive chemical residues and sanitization fluids from the chamber.

### Q: What components are included in the drainage system BOM?
**A**: The bill of materials includes a control valve for flow regulation, a drain pipe network, floor drain grates for surface collection, and P-traps to prevent backflow and contain odors.

## 6. Manufacturing Compliance
- ISO 8770:2010 - DRAINAGE SYSTEMS FOR BUILDINGS AND STRUCTURES
- DIN EN 752:2017 - DRAIN AND SEWER SYSTEMS OUTSIDE BUILDINGS
