Economic Case



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
