# Industrial Specification: Brine Tank

## 1. Technical Definition
A container that holds and stores brine solution for the regeneration process in a water softener system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1.5 bar (0-22 psi) internal pressure, 5-40°C temperature, 0-100% brine concentration**. Failure boundary: **Plastic deformation at 2.1 bar (30.5 psi) internal pressure, stress cracking at 60°C with 25% brine concentration, brittle fracture at -10°C**, Mechanism: **Polymer creep under sustained pressure exceeding yield strength (HDPE: 26 MPa), environmental stress cracking from sodium chloride solution at elevated temperatures, thermal contraction mismatch at low temperatures**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Calcium sulfate precipitation exceeding 2.1 g/L solubility limit | 8 | Crystalline scaling on internal surfaces reducing brine flow to &lt;0.5 L/min | Installation of 5-micron pre-filter with citric acid injection system maintaining pH&lt;6.5 |
| UV radiation exposure exceeding 1500 kJ/m² at 340 nm wavelength | 8 | Polymer chain scission reducing tensile strength by 40% within 12 months | Carbon black additive at 2.5% concentration providing UV absorption coefficient of 0.85 |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

**Downstream Applications**: Residential Water Softener Systems, Commercial Water Treatment Systems, Industrial Water Purification Units  

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

### Q: What materials are best for industrial brine tanks in corrosive environments?
**A**: For corrosive environments, fiberglass-reinforced plastic (FRP) and stainless steel brine tanks offer superior chemical resistance and durability compared to polyethylene or polypropylene options.

### Q: How does the brine well function in a water softener tank?
**A**: The brine well concentrates salt solution during regeneration, allowing efficient drawing of saturated brine into the resin tank to recharge ion exchange beads and restore water softening capacity.

### Q: What maintenance is required for industrial brine tanks?
**A**: Regular inspection for cracks or leaks, cleaning of salt grids/platforms to prevent bridging, and monitoring brine concentration levels are essential maintenance tasks for optimal brine tank performance.

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
- CE MARKING - PRESSURE EQUIPMENT DIRECTIVE (PED) 2014/68/EU
