Composting guidelines: 

1. 

Take into account any munici-
pal regulations on composter 
placement.

2. 

Use a suffi

  ciently large 

composter which will house 
left overfood, sludge bags and 
the required additives.

3. 

Always supply additive to 
the composter when adding 
waste.

4. 

If needed, stir the compost 
and supply additive. A suitable 
additive is e.g. a mixture of 
peat and woodchip. The peat 
will absorb odours and extra 
fl uid and woodchip will ensure 
oxygen circulation. When the 
sludge bag is placed in the 
composter, a larger amount of 
additive is supplied.

5. 

When replacing the sludge 
bag, use protective gloves and 
wash hands aft er touching the 
sludge bag or compost.

The sludge bags may also be 
composted in a so-called garden 
compost for plant residue. The 
bottom of the garden compost 
must be sealed with e.g. tarpaulin or 
construction plastic. A frame can be 
built around the compost, together 
with a lid to prevent water from 
entering. The bottom layer of the 
garden compost is fi lled with twigs. 
A layer of plant waste or other ad-
ditive is always added on top of the 
sludge bag. 

The “raw compost” removed from 
the composter or compost requires 
post-composting. 

A suitable time for post-composting 
is one year. This ensures the com-
post is hygienic. Use the compost 
material primarily for decorative 
plants. 

5.3.2 Sludge removal using a 
vacuum truck

Sludge removal using a vacuum 
truck is normally performed twice a 
year. Vacuum truck emptying is not 
the default setting in the treatment 
plant. Sludge pumping into the 
sludge bag is enabled until vacuum 

truck emptying is enabled via the 
soft ware (see section 4.3).

When vacuum truck emptying has 
been selected, the sludge removal 
reminder comes automatically 
every six months. The reminder is 
a guideline. The best way to deter-
mine the need for sludge emptying 
is to perform a settling test every 
two months. See the settling test 
instructions in section 5.3.2.1. 
When the settling test result shows 
a sludge amount of over 500ml with 
a 90-minute settling, it is time to 
order sludge emptying. 

1. 

Check the sludge amount 
in the process tank with the 
settling test.

2. 

Order sludge emptying when 
necessary.

3. 

Aeration must be active 
during vacuum truck 
emptying. If the process 
tank does not show bubbles, 
change the X3 into the 
X6 socket to force the 
compressor on. Aeration 
starts immediately in the 
process tank.

4. 

The process tank is emptied 
from the front of the tank 
(picture 37) minding the 
aeration disc at the bottom 
(picture 38) until the 
sludgepump appears .

5. 

At the same time, also empty 
the storage tank entirely 
(picture 39). Mind the pump 
and level switch at the bottom 
of the storage tank

6. 

Transfer the compressor plug 
back to its own place aft er 
emptying.

7. 

Acknowledge the sludge 
removal reminder or reset the 
sludge counter (section 4.3).

8. 

Lock the treatment plant 
cover.

NOTE! Mind the pumps, level 
switch and the aeration disc at the 
bottom of the process tank during 
sludge removal!
