23-09: Design and Practical Considerations for Large Scale Asbestos Cement NDCT RefurbishmentsMultiple large power stations in South Africa operate using natural draft wet cooling towers (NDWCT). Most of these cooling towers were built using asbestos cement fill and have reached their end of life. Poor water quality at many of these plants has resulted in severe fill fouling which has led to significant reductions in cooling tower performance. In 2020, projects were initiated to replace the asbestos cement fill of multiple large NDWCTs to
