The chemical feed system shall be capable of traced inhibitor feed control, 24 hours, 7 days remote web monitoring, accessibility and historical data availability and retrieval capability. The feed control shall not overfeed chemicals but to maintain tight control, optimize the cycles to 3 cycles to reduce chemicals, water use and sewage costs. The system shall be able to control biological activities by confirming the biocide feed and then inject chlorine via ORP to minimize legionella bacteria in the cooling tower water. All feed chemicals shall be contained in the event of a spill or leakage.
