PORTABLE DEPOSITION MONITOR   PDM-1

The PDM-1 Portable Deposition Monitor is designed to effectively simulate the operating conditions of plant heat transfer equipment for evaluation of the effects of a chemical treatment program. The Portable Deposition Monitor provides direct observation of heat transfer surfaces. In conjunction with traditional monitoring tools, such as corrosion coupons and corrosion rate meters, the Portable Deposition Monitor performs a comprehensive diagnostic monitoring of cooling systems for chemical processing, industrial manufacturing, and electric power generation plants. Proper identification and treatment of heat transfer surfaces are essential to prevent decreased heat transfer and ultimately, system failure.

APPLICATIONS

    The Portable Deposition Monitor may be used to evaluate the following:

bulletNature of Deposits
bulletEffects of changes in pH limits, inhibitors, dispersants, microbiological control agents, cycles of concentration, and                 water  velocities
bulletSeverity of process leaks and their operational effects
bulletMerits of various materials of construction of replacement equipment    

DIAGNOSTIC CAPABILITIES

bulletBiological    Attachment of macro organisms and/or microorganisms to a heat transfer surface with associated adherent slime.
bulletChemical    Formulation of depositions at the heat transfer surface due to chemical reaction. The surface material is not regarded as a reactant.
bulletCorrosion    Accumulation of corrosion by-products on the heat transfer surface.
bulletParticulate    Accumulation of fine, distinct solids suspended in the cooling water; likely to become a deposit on the heat transfer surface due to gravity (sedimentation fouling).
