Abstract

The application of extremely low frequency (ELF) electromagnetic fields as an effective method for the control of (Dreissena polymorpha) infestation is described. Work focused on monitoring the survival of zebra mussels in which the water was irradiated by an ELF field. The efflux of Ca2+, Mg2+ and other cations from zebra mussels exposed to ELF electromagnetism were used to gauge the efficacy of the method. Experiments examined the application of ELF electromagnetic fields under different environmental conditions: closed and flow-through systems. For a static system, mortality of zebra mussels exposed to ELF EM irradiated water occurred as soon as 5 days. A four-fold increase in the dissolved calcium concentration in the bath water was observed. The rate of change in the calcium concentration points toward a process which affects the mussels’ ability to assimilate calcium from water and also removes calcium from the shells and bodies of the zebra mussels. ELF EM is thought to increase the solubility of calcium carbonate by enhancing the ion-dipole bonding probability of water with dissolved salts. A qualitative model is presented to interpret experimental findings.

Availability

Linear Kinetic Cells are available for out of water or underwater installations. Many sizes are in stock and ready for immediate shipment. Those that are not in stock will generally have approximately a one week shipment time.

Labor

Chemical treatment requires continuous monitoring, adjusting feed, servicing of feed equipment, handling, and extensive water testing required to maintain proper water chemistry. The LKC System is self monitoring and requires no maintenance.

Safety

Safety is the most feared part of using chemical treatment in water systems. There have been many cases of severely burned hands, arms, and faces of persons handling chemicals. The LKC System requires no chemicals. Places to use: The LKC System can be used in any water system. The places of use range from up to 24" main water intakes, to actually putting the cell into a process water pipe line as small as ½”. The LKC System works in any size water system no matter what the size. Each system is designed to fit the need.

Space

The LKC System requires little room for installation since the entire cell is placed directly into the water line, requiring only electrical service. Continuous Treatment: The LKC system operates automatically, 24 hours a day with no assistance or monitoring.

Expenditure

You can normally own an LKC System for less than it costs to operate a chemical system for one year. OEM Services: Ener-Tec, Inc. maintains a qualified engineering staff experienced in assisting staff engineers in solving their scale control problems.
