Based on data regarding significant desalination projects in the United States, the average capacity is approximately 1 million gallons per day.
While the term "average desalination plant" can vary globally depending on size and purpose, a key reference point for the United States indicates a typical capacity for significant projects. According to Wastewater Digest, there are 50 to 75 significant desalination projects annually in the U.S., and these projects have an average capacity of approximately 1 million gallons per day.
This figure represents the potential output of treated water from these facilities. It's important to note that this average is derived from "significant projects" within the U.S., which may differ in scale from smaller, more localized units or much larger, industrial-scale plants found elsewhere in the world.
Key Details from the Reference:
Here's a breakdown of the information provided by the source:
- Location: United States
- Scope: Significant desalination projects (50-75 per year)
- Average Capacity: Approximately 1 million gallons per day
- Primary Technology: Membrane processes (like Nanofiltration - NF, or Reverse Osmosis - RO)
Understanding Desalination Capacity
Desalination plant capacity is typically measured in gallons per day (GPD), million gallons per day (MGD), cubic meters per day (m³/day), or liters per second (L/s). A capacity of 1 million gallons per day is substantial and can serve the water needs of a significant population or industrial demand.
Common Capacity Measurements:
| Unit | Equivalent Gallons Per Day (approx.) |
|---|---|
| 1 Million GPD (MGD) | 1,000,000 GPD |
| 1 Cubic Meter/Day | ~264 GPD |
These plants predominantly rely on advanced technologies, with membrane processes like Reverse Osmosis (RO) being the most common method for removing salts and impurities from saltwater or brackish water.
