| Abstract | ||
| This research included the effect of biological fouling on the efficiency of open recirculating cooling water system in medical city hospital of Baghdad . It showed the relation between fouling deposit and conductive heat transfer resistance . The fouling deposits caues serious problems such as scales and corrosion , (( Utilizing Vials)) method used to determine the quantity of microbiological growth . Sodium hypochlorite (Naocl) used as chemical treatment to control biological fouling growth in this system . It is found that 0.1- 0.2 PPm is the optimum concentration used to control bacterial growth at pH rang 6.5-7.5. Other sources of chlorine is calcium hypochlorite Ca(Ocl)2 | ||
