92-13: Biocide Efficacy vs. Acid Producing and Iron Oxidizing Bacteria Miscellaneous

92-13: Biocide Efficacy vs. Acid Producing and Iron Oxidizing Bacteria MiscellaneousProcedures have been developed for the successful evaluation of four water treatment biocides versus the acid producing bacteria Thiobacillus novellas and the iron oxidizing bacteria Leptotrhix discophoro, Hyphomicrobium indicium and Sphaerotilis natans. The evaluations were conducted at pH 7. 0 and ambient temperature. Each biocide was tested at concentrations that represent recommended treatment dosages for industrial water systems. The Biocidal

we compare several chemistries for the inhibition of such scale formation

are the following: equipment selection

This paper highlights specific problems associated with a Cold Water Basin Cleaning in an eleven (11) cell cross flow cooling tower in Northern Alberta at the Syncrude Canada Site

and the replacement of the cooling tower fill rings

The velocity at design point and the change in velocity affect the steam duct design and the tube bundle design

and operational reliability for evaporative cooling equipment

We're concerned about our customers' property -conservation and fully realize that having no losses preserves property and profits

Water resources are used for many well-defined purposes including domestic and industrial consumption

and sample energy value to obtain the capital worth of colder water
