New desalination concept: the solar evaporator and condenser system (SEACS)
- GDC International, Inc., Chicago, IL
A new concept for a solar-powered, modular desalination plant has been developed. Plants will utilize a Solar Evaporator and Condenser System which provides a simple, reliable, and low-cost method for desalination. The system is an augmented solar still. Air drawn at low velocity over glazed solar ponds picks up moisture and transports it to a condenser where it picks up the latent heat of condensation. The warm seawater then flows by gravity through the ponds and is pumped over an evaporator pad at the air stream inlet. Most of the latent heat of condensation recovered at the condenser will provide additional moisture to the air stream. The cold brine will flow by gravity back to the sea. Product water from the condenser is stored for subsequent use by the community. The level of technology is low. Major components are low speed pumps and fans, heat exchangers, battery storage systems, and photovoltaic power panels. Plant capacity is determined by the number of modules in the plant. Total electric power requirements are anticipated to be as low as 1.2 to 1.5 kWhr/m/sup 3/ of product water. Cost of water production over the 20-year plant life is estimated to be $2.40/m/sup 3/. System is attractive in its simplicity, both from a construction and operation standpoint.
