Pilot-scale cooling tower to evaluate corrosion, scaling, and biofouling control strategies for cooling system makeup water.
Pilot-scale cooling towers can be used to evaluate corrosion, scaling, and biofouling control strategies when using particular cooling system makeup water and particular operating conditions. To study the potential for using a number of different impaired waters as makeup water, a pilot-scale system capable of generating 27,000 kJ∕h heat load and maintaining recirculating water flow with a Reyn...
متن کاملBiofouling control in water by various UVC wavelengths and doses.
UV light irradiation is being increasingly applied as a primary process for water disinfection, effectively used for inactivation of suspended (planktonic) cells. In this study, the use of UV irradiation was evaluated as a pretreatment strategy to control biofouling. The objective of this research was to elucidate the relative effectiveness of various targeted UV wavelengths and a polychromatic...
متن کاملBiofouling and biocorrosion in industrial water systems.
Corrosion associated with microorganisms has been recognized for over 50 years and yet the study of microbiologically influenced corrosion (MIC) is relatively new. MIC can occur in diverse environments and is not limited to aqueous corrosion under submerged conditions, but also takes place in humid atmospheres. Biofouling of industrial water systems is the phenomenon whereby surfaces in contact...
متن کاملBiofouling Control Using Ultrasonic and Ultraviolet Treatments
ABSTRACT: Experiments were conducted at the Natural Energy Laboratory of Hawaii to determine the effectiveness of non-chemical techniques to control biofouling. The two techniques investigated were ultrasonic and ultraviolet. The colonization of microorganisms attracts higher order organisms; therefore, deactivation of microorganisms to prevent colony should reduce the fouling propensity. The m...
متن کاملCooling Water System Modelling for Control and Energy Optimisation Purposes
Utilities account for a significant portion of the fixed cost associated with running a petrochemical plant, however, utility optimisation has not received much focus until recently. This change was driven by rising energy prices, stricter environmental policies, and the threat of climate change. Several utilities are used including steam, compressed air, nitrogen, cooling water, refrigeration ...
