About this file
This document contains data and specifications for chemicals and water treatment services required at the Northport VA Medical Center. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 2 is soliciting proposals for water treatment of four cooling towers with a total capacity of 2,800 tons and recirculation rate of 3,150 gallons per minute, closed chill water systems with a volume of 55,000 gallons and makeup of 100,000 gallons per year, and steam systems producing 90 million pounds of steam annually with 5 million gallons of makeup water per year at 50% hardness of 1-150 parts per million. Bidders must provide details on proposed chemicals including active components, dosages, costs, and testing limits for corrosion inhibitors, biocides, scale controls, oxygen scavengers, alkalis, and neutralizing amines to treat the described water systems.
