as depth and digestion increases. More than 15" (38
cm) may require a reduction in recirculation rate. A
sludge accumulation of greater than 24" (61 cm) in
the sedimentation and 15" (38 cm) in the anaerobic
chamber requires pumping.
PART C: Sedimentation Chamber – collect samples from
the outlet baffle of the sedimentation chamber for the
following analyses:
1.
Scum – 0" to 12" (0-30.5 cm) is common, so long as it
is not rising above the partition wall. If so, punch down
using ladle.
2.
Sludge – A range of 0" to 24" (0-61 cm) is common.
Typically brown and settled, becomes gray or black as
depth and digestion increases. A sludge accumulation
of > 24" (61 cm) in the sedimentation chamber and 15"
(38 cm) in the anaerobic chamber requires pumping.

OPTIONAL WATER QUALITY ANALYSES
PART A: Clean Water Storage Chamber – Collect samples from the clean water storage chamber to be used for the
following analyses
1. pH – Measures the hydrogen ion-concentration and is determined with the use of the pH test strips included in the
Fusion
Maintenance Kit. Dip a test strip into the water sample for 1 second, remove, and read by comparing to the color
®
chart provided on the container. A pH = 7.0 is neutral. The range suitable for biological activity is 6.5 to 7.5. Recurring
results outside this range should be investigated – check the water source for the home or business, chemical use, etc.
2. NO
N – Determined with the use of the nitrite test strips included in the Fusion

the water sample for 1 second, remove, allow to react for 30 seconds and read by comparing to the color chart provided
on the container. Nitrite-nitrogen is an intermediate step in the oxidation of ammonia to nitrate and the reduction of
nitrate. 0 to 3 mg/L is common and 1mg/L is average. The presence of nitrite is indicative of biological activity. The
absence of nitrite could be due to a young system or a recirculation rate that is too high. To correct low nitrite readings
in established systems, decrease the recirculation rate.
