non-chemical zebra mussel control
non-chemical zebra mussel control
(OP)
prior to construction of a FGD system we're going to need to remove/relocate out sodium hypochlorite tank. as opposed to relocating it and continuing the use of chemicals for zebra mussel control i've begun research on non-chemical methods. does anyone know of any non-chemical commerical applications in the power industry?
thanks for any help.

RE: non-chemical zebra mussel control
About 12 to 13 years ago when I was in the power industry I remember an article in a trade magazine (either power or power engineering) about zebra mussel control. One method that was researched was to re-circulate the waste heat from the power plant to heat the service water system intake to a temperature the mussels could not survive, obviously this was not a normal operation and required a great deal of coordination on the service water system.

I've been involved in trying to kill theses things for over a year now. Other than chemical dosing the only other techniques I've heard of are mechanical cleaning, CO2 pellet blasting, freezing, desication, heating and oxygen deprivation.
I've successfully used desication and oxygen deprivation.

As a former water treatment chemical salesman, who sold chloride dioxide for controlling zebra mussels, by non-chemical, do you mean:
(1) Not purchasing chemicals, or
(2) If chemicals generated onsite, such as ozone, this would be acceptable, or
(3) No chemicals to be used or injected into cooling water!
Please define. Ozone works well. Likewise, UV light works extremely well in larvae stage. A combination of both(ozone + UV Light) keeps zebra mussels, pathogens, slime forming bacteria in check.
