is the leading distributor of Sentinel Chambers for determining
the effect of treatments and ecological changes on living biological
indicator organisms. The chambers are supplied with the organism
and media of interest. Once placed in the test environment, the
specialized chambers quickly equilibrate with the surrounding environment.
Following appropriate periods of exposure to the environment, the
small chambers are easily recovered and the indicator organisms
extracted and examined to determine viability.
Sentinel Chamber testing system is specially designed to
monitor the efficiency of water and wastewater treatment methods
on potential pathogenic organisms; monitor the efficiency of disinfection
procedures used in food processing against potential pathogens;
and monitor the effect of environmental perturbations on normal
soil or aquatic organisms.
application of Excelsior Sentinel systems is assessing the disinfection
efficiency of a particular wastewater treatment process for the
destruction of parasite eggs.
loaded with Ascaris suum eggs and the biosolid of interest,
are placed within the sewage being processed and subjected with
the surrounding biosolids to the treatment. After the treatment
process, the Sentinel Chambers are recovered and the Ascaris
suum eggs are extracted. A qualified laboratory examines the
eggs to determine if they are still viable after exposure to the
treatment process. For wastewater applications, the sentinel chambers
are routinely supplied with Ascaris suum eggs in water, anaerobically
digested municipal biosolids, sand, or biosolids provided by the
users. Thus, the Sentinel Chamber system can be tailored to
the specific process and biosolid of interest.
at Excelsior Sentinel, Inc. will work with you to determine the
best type of Sentinel ChamberSS and indicator organisms that will
meet your environmental monitoring needs. Excelsior Sentinel,
Inc. does not offer post-treatment examination of chamber material
for viability assessment, but will provide technical support on
organism extraction methods to the users and testing laboratories
selected by the users.
