The Performance of Organic Phosphonate HEDP in Water Treatment
The Performance of Organic Phosphonate HEDP in Water Treatment Previous Next Chemical water treatment is a chemical technique that uses chemicals to eliminate and prevent scaling, reduce corrosion, kill bacteria and algae, and purify water.
2 moiety) in particular are used extensively in cooling water treatment programs (5), oilfied applications (6), and corrosion control (7). AMP (amino-tris-(methylene phosphonate)) is one of the most common ami-nomethylene phosphonates and a very effective scale inhibitor (8). Schematic

The Role of Organophosphates in Cooling Water Treatment
Six phosphate based inhibitors selected are Sodium Hexametaphosphate (SHMP), Sodium tripolyphosphate (STPP), tetrasodium pyrophosphate (TSPP), Sodium Orthophosphate (O-PO 4), Aminotrimethylene Phosphonate (ATMP) and Hydroxyethylidene diphosphonate (HEDP), these are frequently used in non-chromate based cooling water treatment.
Choice of Phosphonate: From the two most commonly used phosphonate for cooling water treatment HEDP is preferred to ATMP for the following reasons: . ATMP is more corrosive to Cu cooling systems involving Cu or Cu alloys, are therefore very sensitive to ATMP. With ATMP one would then have to use Cu corrosion inhibitors like Thiazoles and Trizoles making the treatment more expensive.
Phosphorus Elimination in Cooling Tower Treatment Program
Based on this information, U.S. Water developed new cooling water treatment technology and worked with a refining plant in the Midwest to help them achieve their goal of reducing phosphorus
Cooling Towers, evaporative condensers and fluid coolers are a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water's temperature. The warm process water enters the cooling tower from the top through spray nozzles, which is referred to as the distribution system.
PRACTICAL APPLICATIONS IN THE TREATMENT OF NON-CHROMATE
245 PRACTICAL APPLICATIONS IN THE TREATMENT OF NON-CHROMATE COOLING WATER SYSTEMS AT PRIMARY METAL PRODUCERS Glenn Matys Betz Inc. 3026 Solandt Road Kanata, Ontario Canada, K2K 2A5 ABSTRACT Reduced corrosion through the installation of more resistant metallurgies in cooling circuits is not always feasible when economic, fabrication and availability factors are taken into consideration.
Cooling water pH is kept in the neutral range. 3) Low Phosphate - the alternative name is "extended" phosphate programs and is commonly run under neutral to somewhat alkaline conditions and with lower PO4 concentrations. 4) Phosphonate - this is the commonly called "organic" treatment that has become the industry standard.
