Water treatment technologies for thermal storage systems: Final report. [Cool storage systems]
Water has many properties which make it an almost ideal medium for storage and transfer of cooling energy. However, even pure water cannot be used in cooling thermal storage systems without careful attention to water chemistry management. There are three water conditions which may cause problems in cooling systems: corrosion, biofouling, and sludge deposits. Corrosion and biological fouling are usually the most common problems, but both can be readily controlled by suitable internal chemical treatment. Starting a system with good pre-operational cleaning procedures is essential and is probably the best route to long-term waterside efficiency and trouble-free performance. A wide variety of reference materials, professional and educational assistance, and water treatment chemical supplier support is readily available. The direct costs of good chemical management are not high and are a good investment when compared to the expenses that might be incurred if no attention is paid to system water chemistry. This discussion is not intended to be a detailed technical treatise on water chemistry or engineering technology. Rather, it is intended to serve as an introduction and interpretation of how good water treatment practice can be applied to, and benefit, thermal storage system operations. 3 figs., 11 tabs.
