# Industrial Specification: Filter Cartridge/Media

## 1. Technical Definition
A replaceable filtration element that physically removes contaminants from water in circulation systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-6.9 bar differential pressure**. Failure boundary: **7.0 bar differential pressure (burst pressure)**, Mechanism: **Tensile failure of pleated media due to excessive pressure differential exceeding yield strength of polypropylene fibers (35 MPa)**.

### 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.

| 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 loading exceeding 5 g/L concentration | 8 | Flow restriction causing 80% pressure drop increase | Install 100 μm pre-filter with differential pressure monitoring at 2.3 bar |
| Chlorine concentration exceeding 0.5 ppm in feedwater | 8 | Polymer degradation reducing filtration efficiency below 95% at 10 μm | Implement activated carbon pretreatment with oxidation-reduction potential control at 200 mV |

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

### Q: What materials are commonly used in filter cartridges for machinery water systems?
**A**: Common materials include polypropylene, polyester, cellulose, activated carbon, ceramic, and stainless steel mesh, each selected for specific filtration needs and compatibility with water chemistry.

### Q: How often should filter cartridges be replaced in industrial water circulation systems?
**A**: Replacement frequency depends on water quality, contaminant load, and system pressure. Typically, cartridges are replaced every 3-6 months or when pressure drop indicates clogging, following manufacturer guidelines.

### Q: What are the key components in a filter cartridge bill of materials (BOM)?
**A**: A standard BOM includes the core tube, end caps, filter media (e.g., polypropylene or activated carbon), and gaskets or O-rings to ensure a secure seal and prevent leaks in the system.
