EnviroTower Water Treatment Solution - Cooling Tower Global IT R&D Centre India - Case Study
A Global Multinational company having their R&D and IT center at a South India facility consists of 8 buildings and equipped with 1,200TR Chillers to maintain the right temperature. They were using traditional chemicals for Scale, Corrosion and Bio growth fouling which increase the operational cost of cooling system, with descaling done once in every 4 months.
WATER SYSTEM CHALLENGES
Mineral Scaling: Makeup water that is supplied to the condenser basin in an open cooling water system contains dissolved minerals. As evaporates the water becomes supersaturated with these minerals. Calcium carbonate, for example, precipitates as scale on pipe, equipment and surfaces, impeding heat transfer and reducing system efficiency.
Microbiological Contamination: Algae and bacteria make the treatment of cooling tower water particularly difficult. Warm, wet, nutrient-rich environments are ideal for micro-organism growth, leading to biofilms and slimes. Slime restricts airflow in cooling tower fill, clogs filters and creates corrosive conditions. Some biologic outbreaks can also be harmful to humans if not controlled properly.
Corrosion: Most of the corrosion on iron, steel, and galvanized surfaces is microbial induced. Biofilms allow microbes to create highly corrosive environments which result in corrosion pits. General corrosion can also occur due to low pH conditions in the water. Copper corrosion control is critical to protect the investment in chillers, condensers, and other refrigeration equipment.
