Management of biological systems for continuously-operated solar saltworks

Abstract

The goal of every solar saltworks with seawater intake--continuous and economic production of high quality salt (sodium chloride) at design capacity-requires ability to simultaneously manage and coordinate physical systems with biological systems in the concentrating and crystallizing ponds. This effort requires close control of specified salinities, depths, and brine transfers, frequent surveillance and adjustments of planktonic and benthic communities and their key microorganisms, and timely recognition and correction of developing problems. This report reviews features and concepts that facilitate biological and physical management, considers causes and effects of common and severe disturbances and their solutions, and provides information that enable biological systems in the ponds of a solar saltworks aid rather than harm salt production. ?? 2009 Global NEST.
