87-18: Microbicidal Efficacy of BNPD Against Legionella Pheumophila Legionella

87-18: Microbicidal Efficacy of BNPD Against Legionella Pheumophila LegionellaThe veracity of in vitro biocide evaluations reviewed in the context of Legionella Pneumophila field study disinfections. In particular, a new nonoxidizing biocide is presented which appears to be uniquely effective in controlling populations of L. P. Efficacy of biocidal disinfections is discussed in terms of biomass penetration and mode of cellular destruction.

This unique chemical approach provides multimetal corrosion control

Laboratory and field case studies will be discussed

Field-testing over an 18-month period has identified two viable approaches to zero-blowdown (high eyolo) operation

This helps in increasing the cycles of concentration of the cooling tower and also reduces the size of the disposal pond or a brine concentrator in case of a zero discharge permit plant

and overall reduction in megawatt capacity of the Combined Cycle Plant

which could also be titled “Cooling Water 101”

specialized procedures were developed to characterize the condition of different materials

Many types of monitors are used in cooling systems to determine fouling rates

There are several methods to measure biofilm

When the City of Burbank engineers decided in 1967 to use sewage plant effluent for cooling tower make­up without removing the phosphate and without final filtration

which traditionally relies on fresh surface water or groundwater sources

most of the splash grid fill collapsed catastrophically and fell into the basin
