1. Odor

Offensive odors are often the result of insufficient or

inappropriate bacterial growth. Causes may include a young

or unestablished system, insufficient air introduction, or the

addition of detrimental chemicals or poisons into the system.

Ensure the blower and air delivery systems are functioning.

Check with the owner regarding chemical use and disinfection

habits. Check all risers and lids to ensure an airtight seal.

2. Foam Formation

Foam forrmation is observed in the following situations:

1. In the early stage of operation when the arerobic bacteria

colony is establishing itseft.

2. When an excess amount of air is supplied for aeration

3. When the difference between ambient temperature and

water temperature is great.

4. When an excessive amount of detergent is introduced.

In most cases, foam will disappear with proper operation.

When excessive amount of detergent have been introduced

to the system remind the owner to use appropriate amount of

detergent.

3. Cloudy Treated Water

• Check the amount of scum and sludge:

If too much scum or sludge is observed, transfer them to the

first chamber and adjust recirculation flow rate as well as

backwash time, frequency and duration. (See backwash flow

adjustment)

• Check the aeration situation:

If uneven bubble generation is observed, adjust valve (1). If

aeration is weak, flush the aeration pipe with air or water.

• Check the recirculation flow rate:

If the recirculation flow rate has increased after the last

inspection, the aeration pipe may be clogged. Flush the

aeration pipe with air or water. If the recirculation flow rate

has decreased after the last inspection, the airlift pump or

recirculation pipe may be clogged. Clean them with a brush

and running water.

• Check the color of the returning sludge from the backwash

pipe:

If the color is abnormally dark, decrease the recirculation flow

rate accordingly. If the TSS of the water from anaerabic to

aeration chamber is high, check the sludge accumulation. If

the sludge accumulation reaches the upper limit, pump out

the sludge. If not, backwashing the anaerabic chamber by

using a manual backwash tool (figure 18) may assist.

TROUBLESHOOTING

4. Blower

Blower motor does not run, with power connected:

• Check the electric supply to the panel, ensuring 120 volt service.

• Check that all breakers and fuses in the panels are intact.

• Check the blowers auto stop mechanism (See pages 17 and 18).

Little or No aeration/ backwash air:

• Check the blower motor is running.

• Check the air line piping connections at the blower.

• Check the air filter and clean or replace if necessary.

• Check the diaphragms and replace if necessary.

• Check the air piping for leaks, clogs, or dislocations and correct

accordingly.

• Verify check valves (if installed) in supply lines are installed

correctly.

Blower- Manual backwash does not work.

• Manually toggle between recirculation and backwash several

times, listening closely for a light click within the unit.

• If the unit clicks, but the air does not switch from aeration to

back-wash, consult the factory.
