Description: Das Projekt "Almeria solar powered reverse osmosis plant" wird vom Umweltbundesamt gefördert und von DaimlerChrysler Aerospace AG durchgeführt. Objective: To demonstrate, that small scale PV powered water desalination plants can be constructed in a compact and cost efficient way. This type of plant is urgently needed in Southern Europe and Developing Countries. Intensive publicity is intended and good commercialisation is expected (100 systems potential market in Spain only). General Information: On the site of the ALMERIA university, brackish water is pumped from a well of 60m. Drinking water (about 8000 cbm per year) obtained by a reverse osmosis plant is stored for consumption. A 23.5 kWp PV generator supplies the required energy. Number of subsystems: 1 Power of subsystems: 23.5 kWp Total power: 23.5 kWp Module description: 612 AEG type PQ 10/20/01;(Typ I) + 306 AEG type PQ 10/40/01;(T.II) (I): 20 10x10cm poly crist. cells, 6 V,16.5 W (II): 40 10x10cm poly crist. cells, 12 V,38.4 W Very high resistance glass; UV stabilized PVB; 6.7 kg; 0.25 or 0.5 sqm. Connections: type 20: 36 series, 17 parall.: type 40: 18 series, 17 parall. Support: on racks Max. power tracker: included in inverter Charge controller: charge/discharge regulator: special design, microprocessor controlled. Battery: Spanish TUDOR, 110 cells Battery Volt.: 220 V; Battery capacity: 2240 Ah.(at 100 h). (1650 Ah (10h); type C 10 Battery capacity: 493 kWh.(at 100 h). Inverter: (for well water pump only): AEG, Solarverter, type SV3 sinusoidal, transistor-pulse type, 3 kHz. Input nominal: 130 to 300 V DC in; max 16 A Dc; Output nominal: 3.3 kVA; 13 to 127 V out; 3 phases; to 50/60 Hz. Load description: PLEUGER submersible pump NE612 for raw water pumping. (three phase, AC motor, hence inverter necessary). 4.2 cbm/h, header 30 m. Rated power 2.2 kW. ROCHEM (Hamburg) reverse osmosis, type RORO 1535-B 709165; presses raw water through membrane. Input: 92 cbm/day at 7000 ppm; Output: 60 cbm/day at smaller than 500 ppm. New type of PLATE MODULE system, with turbulent flow on the feed water side and hence less membrane scaling and fouling which leads to less maintenance. The pressure pump of the RO system works with 220 V DC motor, 6750 W, avoiding inverters. Monitoring: Weather station; Reading every 10 seconds six relevant plant data, averaging over ten minutes, storing on floppy. (DAM 800 data acquisition system by TELEFUNKEN). Stored data: (1) Insolation, array plane. (2) amb. temp. (3) module temp. (4) array output energy. (5) energy to and from battery. (6) inverter dc energy. Achievements: While the pv generator and the batteries worked without problem the water pumps, the reverse osmosis plant, the inverter and the monitoring system had several, partly major, failures. The Final Report on System Monitoring (5 June 95) analyses 32 month of operation and puts in evidence: the system is well designed for its task; however the frequent failures of some components decrease its effective utilisation. The plant will continue to operate after the end of the project with some improvements (new pumps, new membranes, etc.)...
