5.3 Sludge removal
In the WehoPuts 5 and 10
treatment plants, you can remove
sludge by either using a sludge
bag or using a vacuum truck.
The sludge removal reminder
can be enabled according to the
instructions in section 4.3 when
using a sludge bag. Selecting a
vacuum truck sludge removal
reminder comes automatically
twice a year.
5.3.1 Sludge removal with
sludge bag
During the cleaning process,
residue sludge is pumped into a
separate sludge bag that needs
to be regularly emptied. In the
WehoPuts 5 model, the bag needs
to be emptied every 2 to 4 months,
depending on family size and treat-
ment plant load. In the WehoPuts
10 model, the replacement interval
is on average 1 to 3 months. The
sludge bag should be replaced
when the surface of sludge in the
bag reaches the halfway mark. If
no sludge has accumulated in the
sludge bag, see section 6.4.3.

The sludge basket has been
attached to the brackets in the
upper part of the storage tank.
Sludge bag installation and
replacement:
1.
Open treatment plant lid and
move the sludge pipe to the
side before removing the
sludge basket (picture 34).
2.
Lift up the entire sludge
basket.
3.
Release the string holding the
mouth of the bag and lift the
sludge bag up together with
the protective bag. You can
compost the sludge bag with
organic or garden waste.
4.
Stretch the protective bag and
install the sludge bag inside
the protective bag. Bend the
mouths of both bags over
the edge of the basket and
fi x with the ring. Ensure the
bottoms of the bags reach
the bottom of the basket
(pictures 35 and 36).
5.
Install the sludge basket back
in the storage tank.
6.
Insert the residue sludge pipe
back in the bracket.
7.
Lock the lid and wash hands.
NOTE! The bags are installed with
the bottoms touching the bottom
of the basket!
5.3.1.1 Sludge bag composting
The recommended treatment
method for the WehoPuts minia-
ture treatment plant sludge bag is
composting. When complete, the
compost is a good nutrient for e.g.
growing fl owers.
The best way to compost the sludge
bag is to place it in a factory-built
composter together with left over
food or in a garden compost with
plant residue.
