79-11: Biofilm Development and Destruction in Turbulent Flow General

79-11: Biofilm Development and Destruction in Turbulent Flow GeneralMicrobial fouling in power plant condensers decreases heat transfer and fluid flow resulting in energy losses. Biofouling control is generally accomplished by chlorine addition creating potential toxicity problems in receiving waters. A better understanding of fouling film development and destruction (including stoichiometry and kinetics) is necessary to maintain satisfactory effluent water quality while minimizing the effects of biofouling and its

open recirculating cooling water systems are often consider ideal candidates for reusing industrial waste streams

With decreasing water supplies in most industrialized areas of the United States

these positive charged ions can enter the solution only if an equivalent number of positive charged ions of some other elememt is displaced

have finally been overcome to offer designers improvements in the scale

The treatment of water for coolant water towers by means of ion exchange

For several years many cooling towers have been designed with a plume abatement device to reduce or eliminate plume formation under some weather conditions (mainly in winter)

detailing kinetics of film formation for various surface deposited film inhibitors not previously reported

cooling tower plume abatement

The alternative approach reduced treatment costs by 30%

Condensation and rainout of the water is included in the simulation
