  4. INDEX: • Antecedent • Objective • Description R.O. plant • First results • Conclusion

  5. ANTECEDENT • Progressive increase of water consumption due to the increase of population. • Increase of energy request (by fuel sources). • Search of a sustainable development by the promoting the desalination techniques with use of renewable energy for water production. WHY IS DESALINATION SO IMPORTANT AT PRESENT?

  6. ANTECEDENT • The main drawback of the renewable energies (Wind and PV): NOT GUARANTEE A CONTINUOUS AND CONSTANT SUPPLY OF ENERGY

  7. INDEX: • Antecedent • Objective • Description R.O. plant • First results • Conclusion

  8. OBJECTIVES • To observe the adjustment of an RO plant with a renewable energy source. • Related to this work are the projects: OPRODES and OPRORES.

  9. INDEX: • Antecedent • Objective • Description R.O. plant • First results • Conclusion

  10. LOCALIZATION

  11. DESCRIPTION OF THE R.O. PLANT • The main components are: • HIGH PRESSURE PUMP • MEMBRANES MODULE • SENSORS • CONTROL SYSTEM • An advance in the design of the plant would be the installation of an energy recovery system.

  12. CAT 6761 HIGH PRESSURE PUMP • Positive displacement pump with three stainless steel piston pump. Power 30kW. • Maximum flow: 9.8 m3/h. • Power ranges: 7-85 bar. • System of pulleys with a transmission relationship 4:1.

  13. MEMBRANE • KOCH - FLUID SYSTEMS • TFC 2822-SSPremium.(Spiral polyamide). • 1 tube (6 metres long) 6 membranes • Max. Permeation 17m3/day. • Salt rejection 99.75% each. • Total area of 27.9m2.

  17. OPERATION RANGE OF THE PLANT • Minimum operating pressure – 30 bar. • Maximum operating pressure – 68 bar. • Minimum recovery – 15%. • Maximum recovery – 50%. • Minimum electric motor r.p.m. – 800 r.p.m. • Maximum electric motor r.p.m. – 1500 r.p.m. • Minimum power consumption – 5.5 kW. • Maximum power consumption – 21.5 kW.

  20. FIRST RESULTS (1) • Graphics of results The consumption of kW/m3 of product water decreases for higher working pressures. PRODUCT FLOW AND SPECIFICCONSUMPTION

  21. FIRST RESULTS (2) • Graphics of results • For high pressures: • -  Quality of water • - Energy • -  kW/m3 42% FEED FLOW, REJECT FLOW AND RECOVERY FACTOR

  22. INDEX: • Antecedent • Objective • Description R.O. plant • First results • Conclusion

  23. CONCLUSIONS (1) • Our RO plant, which works under variable load, shows us that the optimum performance of the plant (recovery 42%) is between 16 and 18 kW, working pressure from 57 to 67 bars. • In these conditions the specific consumption oscillate into a range of 4.1 to 4.7 kW/m3, and a maximum water production of 4.2 m3/h

  24. CONCLUSIONS (2) • The kinetic energy in brine flow is high, so the installation of an energy recovery is highly recommended. • We will install the most suitable energy recovery for our plant, which is the Pelton turbine. • We think we will obtain an energy recovery between 20-30% for our variable load plant.
