Temp & Algae Control

Studies have been performed and the results show that a properly designed and installed barrier netting system can greatly reduce the potential of lost generation time by the means of capturing and holding algae and debris before it is allowed to enter the coolant intakes

Periphyton is the community of organisms that grow on surfaces in shallow water near the shore of lakes. The dominant organism is normally an attached algae or plant. However, it is a complex community with bacteria, cyanobacteria, fungi, and invertebrates all having functional roles within the community.

In many lakes, the dominant attached algae is Cladophora. In the 1960's and 70's this algae caused serious problems in the near shore zone. It had explosive growth, which detached and fouled plant generation intakes. Research at that time showed that these lakes were receiving an excess of phosphorus, which normally limits Cladophora growth in the shallow, well-illuminated near shore zone.

Most of these lakes are in transition. The introduction of zebra mussels and other species are always changing the ecology of the lakes as well. The population on lake sides is growing rapidly as well. This population, and the related commerce, is inevitably producing pressures on the lakes.

The excessive growth of Cladophora is again becoming a problem. Although current levels remain relatively low compared to those measured in the 1960s and 1970s, prior to effective phosphorus control; the fouling has resulted in increased operational down time at many power generation facilities.
