Method For Controlling Zebra Mussels In Power And Water Plants

US Patent:
5294351, Mar 15, 1994
Filed:
Mar 25, 1993
Appl. No.:
8/037349
Inventors:
David N. Clum - Higdon AL
Frederick Krosner - Signal Mountain TN
Jewel R. Leak - Hixson TN
Assignee:
First Thermal Systems, Inc. - Chattanooga TN
International Classification:
C02F 102
US Classification:
210774
Abstract:
A method and apparatus for controlling zebra mussels in the inlet cell of a utility power plant by isolating a batch of water in the cell from the water supply of a lake or river and the equipment plant by shutting an inlet gate and shutting outlet valves from said cell. The batch of isolated water is thereafter heated to a lethal temperature which is maintained for a sufficient period of time to ensure 100 percent mortality to the zebra mussels within the cell. The water may be maintained in a static condition and heated by a heat exchanger disposed within the cell. Alternatively the water may be fed to a heat exchanger, heated outside the cell, and returned to the cell. The water is heated to a range of approximately 95. degree. F. to 100. degree. F. and held at the heated temperature within the cell for approximately 30 minutes.

Method Of Removing Zebra Mussels From Waterways And Wetted Surfaces

US Patent:
5389266, Feb 14, 1995
Filed:
Jan 11, 1994
Appl. No.:
8/179936
Inventors:
David N. Clum - Higdon AL
Frederick Krosner - Signal Mountain TN
Jewel R. Leak - Hixson TN
Assignee:
Dixstar, Inc. - Chattanooga TN
International Classification:
C02F 102
US Classification:
210747
Abstract:
A method for killing zebra mussels from a bottom surface of a waterway and from the surfaces of watercraft, docks, pilings and similar facilities located within a waterway. The surfaces to be treated are isolated in a batch of water enclosed within a chamber. The isolated batch of water is thereafter heated to a temperature lethal to the zebra mussels and held at that temperature for a sufficient time to kill the zebra mussels. The isolated batch of water and the treated surface are thereafter released from the chamber and the isolated state.
