Abstract

Biofouling in the cooling water circuits of coastal power stations presents considerable problems for their normal operation. Although chlorination is commonly practised, operational problems, safety concerns and environmental issues have made it necessary to look for alternative methods of control. Heat treatment is considered as a viable alternative and is being practised by a few utilities in the USA and The Netherlands. This paper presents data on the lethal and sublethal effects of temperature on the green mussel Perna viridis, a species causing fouling problems for the Madras Atomic Power Station, located on the east coast of India. The mortality pattern and the physiological behaviour (byssus thread production, filtration rare and foot activity index) of the green mussel were studied at temperatures varying from 10 degrees C to 46 degrees C. Synergistic effects of salinity and temperature on mortality were also studied. Exposure of 2 mm size group mussels toa temperature of 39 degrees C showed 50% mortality in 58 min and 100%mortality in 73 min. Mortality was strongly dependent on age (size) of the mussels, young ones being more susceptible than older ones. The study indicated that hear treatment has distinct advantages as an alternative to control mussel fouling in tropical power stations.
