FUSION

Scum – Very small amounts of scum may accumulate in

the corners on the outlet end of the system. This is normal.

Scum, should not be present elsewhere in the clean water

storage chamber unless the recirculation rate is too high or

daily flow exceeds the design capacity. If present, use ladle

to transfer to sedimentation chamber.

Sludge – Test the sludge depth using the sampling device

included in the maintenance kit. The bottom section of the

sampler includes a check valve, which opens as the unit

is lowered into the liquid. When the sampler has reached

the bottom of the chamber and the liquid level equilibrated

at surface level, lift the sampler and this action will set the

check valve and retain the sample in the tubing. Withdraw

the sampler and note the depth of settled solids within the

sample. To release the material in the unit, touch the stem

extending from the bottom section against a hard surface

such as the partition wall in the sedimentation chamber. This

opens the check valve to drain the sample. Typically solids

are brown and well flocced.

Sludge Descriptions:

Black – septic or sewer-like odor due to hydrogen sulfide and

other gases

Brown – undigested sludge is light brown, becomes darker

with digestion, lightly settled

Clear – may see a clear water layer beneath solids if gas

carries solids upwards

Flocced - settled with texture similar to a tuft of wool

Grainy - gritty or sandy texture

Gray - partially digested sludge

Milky – light in color, cloudy, not transparent

Muddy – typically well settled, often present just after startup,

may be due to infiltration

Mustard - an off-color, remnants of digestion are often

yellowish in color

White - sometimes present after new construction often due to

drywall mud

PART B: Anaerobic Filtration Chamber

from the outlet baffle of the anaerobic filtration chamber to be

used for the following analyses:

Transparency – A transparency reading more than 20 cm

is preferred.

Scum – Should not be present unless recirculation rate is

too high or daily flow exceeds design capacity. To correct,

reduce the recirculation and or backwash rate.

Sludge – A range of 0" to 25" (0 to 60 cm) is preferred.

Typically brown and settled, becomes gray to black as depth

and digestion increases.

PART C: Sedimentation Chambe

the outlet baffle of the sedimentation chamber for the following

analyses:

1. Scum – rising above the partition wall. If so, punch down

using ladle.

2. Sludge – A range of 0 - 50" (0 to 120 cm) is preferred.

Typically brown and settled, becomes gray or black as depth

and digestion increases.

be collected as previously described.

N – Determined with the use of the nitrate test

strips included in the Fusion Maintenance Kit. Dip a

test strip into the water sample for 1 second, remove,

allow to react for 60 seconds, and read by comparing

to the color chart provided on the container. Nitrate-

nitrogen is the final step in the oxidation of ammonia.

The test strips provided range from 0-50 mg/L. No or

low nitrate concentrations are common in systems where

nitrifying microbes are absent. To correct high nitrate

concentrations in established systems increase the

recirculation rate.

N – Determined with the use of the ammonia test

strips included in the Fusion

test strip into the water sample and move up and down

for 30 seconds, remove, allow excess water to drain,

allow to react for 30 seconds, and read by comparing

to the color chart provided on the container. Ammonia-

nitrogen is measured using low range test strips, 0-6

mg/L. Low ammonia readings are desirable and require

no changes. To correct high ammonia readings decrease

the recirculation rate.

Dissolved oxygen – Follow the instructions included

with the dissolved oxygen meter. D.O. should be

measured 25 inches (635 mm) below the water level.

Temperature – Most dissolved oxygen meters include

a built-in thermometer which can be used to measure

temperature. Varies with system location.

PART E: Anaerobic Filtration Chamber

pH – The range suitable for biological activity is 6.5 to 7.5.

Recurring results outside this range should be investigated –

water source for the home or business, chemical use, etc.

N – Adjustments should be based on water quality in

the clean water storage chamber.

N – Adjustments should be based on water quality in

N – If this test is desired, it should be conducted

with test strips suitable for the expected concentration.
