The monitor provides a sensitive indication of very low
concentrations of particulate impurities in a flowing
water sample. It is especially suitable for particles
greater than 1 micron in size and can be over 100 times
more sensitive than conventional nephelometric turbidimeters. |

A New Method
for Detecting Condenser Leaks | PDF
File (4,869 KB)
Anyone involved with steam water operations in power plants
appreciates the significance of cooling water leakage
into returned condensate. The severity of problems caused
escalates with higher boiler operating pressures, primarily
due to very sensitive chemistry “balance”
needed to prevent tube deposits, corrosion, and or metal
cracking. |

A Simple Particle
Monitor for Low-Turbidity Waters | PDF
File (2,735 KB)
There is increasing concern over low levels of particulate
contaminants in drinking water and turbidities well below
1 NTU are the goal of many treatement plants (1). In some
cases, a turbidity of less than 0.1 NTU can be achieved,
with a well-operating plant. |

...The particle counter was connected to the effluent
stream of a dual media filter. The filter was monitored
for turbidity and particle counts while the particle monitor
was being used. At the time the particle monitor was connected,
the dual media filter was being used in the direct filtration
mode. The source water was a low turbidity water that
we added a coagulant into, rapid mixed the water, and
then flocculated before challenging the filter. |

Water Filtration Processes | PDF

Filtered
Water is routinely monitored for particles, usually by
turbidiy measurements. In recent years, concern over certain
parasitic protozoa water has led to the use of more sensitive
particle monitoring techniques. Although particle counting
instruments are suitable for such purposes, it is shown
that a simpler, but very sensitive technique, based on
turbidity fluctuations, may also be acceptable. |
