Water Chlorination System: 120 Gallon Contact Tank
Retention tanks are typically utilized to assure adequate contact time to kill bacteria, mix chemicals properly, or allow chemical reactions to fully occur. The retention tank ensures uniform mixing and sufficient residence time to meet the CT (contact time) standard set by most health agencies in the United States. This remains true even when water is flowing continuously. With a 0.6 baffle factor, as tested by the Water Quality Association test labs, it also takes up less space because one tank does the work of 3 normal tanks.
