This technology dramatically reduces major cost components of desalting raw seawater and/or brackish groundwater.
Fixed costs and power are 80% of the overall picture in all existing RO systems. Energy is also the most volatile cost variable.
- The Jepson system reduces these by more than 50%
- Membranes . . . none
Positive Implications of the Jepson System
- Highly competitive globally
- Lower capital costs = rapid payback, lower cost of water, lower entry point
- Lower power costs = lower operating costs, lower cost of water, more environmentally friendly, less susceptible to oil’s price volatility
- Energy recapture possibilities are great – up to 80%
- Smaller footprint = less land, more environmentally friendly, rapid deployment and installation, good for offshore operations
- Pretreatment= capital cost elimination, simpler system, lower operating costs
- Higher water intake utilization = lower pump power and capital costs
- No membranes = lower operating costs, no cleaning chemical pollution, no solid waste, simpler system
- Waste . . . Most traditional waste sources are eliminated
- Water quality . . . Excellent
