Wastewater Evaporation Spray Nozzles for Mining
Evaporative spray systems help mines reduce pond volume, create surge capacity, and concentrate brines without building new basins. NozzlePro provides durable atomizing and fine-mist solutions engineered for tailings ponds, process lagoons, and remediation sites—balancing evaporation performance with drift control and low maintenance.
Applications in Mining Wastewater Evaporation
Tailings & Process Ponds
High-density evaporation arrays to lower pond levels and manage seasonal inflows.
Brine Concentration
Fine-mist systems to accelerate water removal and reduce haul/treatment volumes.
Level & Headroom Control
On-demand evaporation to create storage headroom ahead of weather events.
Odor & Vapor Mitigation
Perimeter fog lines that suppress vapors while contributing to net evaporation.
Benefits of NozzlePro Evaporation Systems
- Volume Reduction – Shrink wastewater inventory to free capacity and lower disposal costs.
- Scalable & Modular – Add masts and nozzles as needs grow; simple piping and controls.
- Drift Management – Match droplet size and pressure to site winds and setback limits.
- Rugged Uptime – Abrasion-resistant materials and strainers for long service in harsh water.
- Operational Flexibility – Zoned operation, seasonal modes, and quick turn-up during storms.
Evaporation Planners & Reference (Illustrative)
Relative Evaporation Index by Weather
Unitless index to compare conditions (higher = more evaporative). Use for scheduling and setpoint planning.
| Ambient Temp (°F) | Relative Humidity (%) | Wind Speed (mph) | Relative Evaporation Index |
|---|---|---|---|
| 60 | 70 | 5 | 0.6 |
| 75 | 60 | 8 | 0.9 |
| 85 | 50 | 10 | 1.2 |
| 95 | 40 | 12 | 1.6 |
| 105 | 30 | 15 | 2.0 |
Droplet Size vs. Evaporation & Drift
Relative evaporation time scales with diameter² (100 µm = 1.0). Choose size to balance evaporation and drift risk.
| Typical SMD (µm) | Relative Evaporation Time | Drift Risk | Typical Use |
|---|---|---|---|
| 50 | 0.25 | Very High | Max evaporation; calm conditions only |
| 100 | 1.00 | High | High evaporation; moderate setbacks |
| 200 | 4.00 | Medium | Balanced evaporation vs. drift |
| 400 | 16.0 | Low | Wind-exposed sites; drift sensitive |
| 800 | 64.0 | Very Low | Perimeter zones; minimal drift |
Basin Reduction Planner
Daily removal using 1 acre-inch = 27.154 kgal. Assumes 30 gph per nozzle (≈0.72 kgal/day/nozzle).
| Basin Area (ac) | Evap Rate (in/day) | Volume Removed (kgal/day) | Nozzles @ 30 gph | Notes |
|---|---|---|---|---|
| 0.5 | 0.10 | 1.36 | 2 | Round up to whole nozzles |
| 1.0 | 0.20 | 5.43 | 8 | Zoned banks recommended |
| 2.0 | 0.30 | 16.29 | 23 | Multiple masts; wind controls |
Air Consumption Planner (Air-Atomizing)
Estimate compressor demand. Multiply per-nozzle SCFM by nozzle count (values at ~40 psi air are illustrative).
| Fluid Rate (gph) | Air per Nozzle (scfm) | 10 Nozzles (scfm) | 20 Nozzles (scfm) | Notes |
|---|---|---|---|---|
| 10 | 2 | 20 | 40 | Light evaporation; low drift |
| 20 | 4 | 40 | 80 | Balanced performance |
| 30 | 6 | 60 | 120 | High output; confirm compressor headroom |
Coverage per Mast (80° Pattern)
Coverage diameter D ≈ 2 × Height × tan(40°). Use to set spacing and overlap on rafts or shore masts.
| Nozzle Height (ft) | Coverage Diameter (ft) | Coverage Area (sq ft) | Comment |
|---|---|---|---|
| 10 | 16.8 | 221 | Close spacing; minimal drift |
| 15 | 25.2 | 498 | Typical mast height |
| 20 | 33.6 | 885 | Wide coverage; watch wind |
Wind-Based Operating Guidance
Use local policies and permits; the guidance below is operational, not regulatory.
| Wind (mph) | Recommended Action | Typical Setback |
|---|---|---|
| < 8 | Normal operation; fine droplets allowed | ≥ 50 ft |
| 8–15 | Increase droplet size or reduce pressure | ≥ 100 ft |
| > 15 | Pause exposed zones; run low-drift heads only | ≥ 150 ft |
