Abstract:

The development of current selection and application guidance is necessary to help Army installations be smart buyers of water treatment for new and existing heating and cooling systems. Manufacturers continue to introduce new chemicals and treatment programs onto the market, including environmentally friendly green chemical products, as old products are discontinued. These products require periodic review to inform Army installations of new technological advances, and of the capabilities of chemical products available in the marketplace. This work demonstrated and evaluated the performance of primary water treatment formulations at Fort Stewart, GA and Fort Hood, TX, using three green chemical technologies 1 the cooling water inhibitor polyaspartate PASP, 2 the cooling water biocide tetrakis hydroxymethyl phosphonium sulfate THPS, and 3 a filming inhibitor made from exthoxalated soya amines for steam line treatment. The study concluded that the three technologies were effective when used according to the recommended application guidelines.
