01-06: Mixed-Oxidant Use in Cooling Tower Maintenance FillsTests using mixed oxidant solution instead of oxidizing biocides (chlorine or bromine) for cooling tower maintenance, and eliminating all other biocides, found: (l) aerobic bacteria countsconsistently less than l000 mL in cooling water (no colonies on the standard Easicult TTC dip slide test), a result rarely achieved using chlorine alone or chlorine with other biocides; (2) ease in maintaining Free Available Chlorine (FAC) concentrations at 0. 2 0. 3
The physical characteristics of wood treated with NON-COM EXTERIOR will be discussed including the effect on strength
Wood samples were taken from all areas of the towers and were subjected to biological
The ISO 9001 quality system presents an outline/philosophical approach for formalizing the quality system function within the manufacturing organization that does not interfere with the normal business operation
Using process simulation and electrochemical data
The pretreatment and corrosion control program used gave excellent results for biological fouling
some feasible alternatives that provide adequate control of amoeba-fed Legionella in cooling towers by employing a combination of US EPA approved organic biocides
such as PVC
Imperfections in the intended geometry and verticality do occur which can have an impact on the stresses in the thin concrete shell structure
Blowdown from water systems using the chromate or chromate/zinc-based water treatments must be treated to prevent chromate and zinc from entering effluent
combined with structural analysis
This paper provides economic penalties for typical fossil power plants
Both methods were employed at the same location during a recent test program
