4. Problems that may occur
4.1 Odour
If installed, used and maintained correctly, the room where the Biolan
Populett is located will remain odourless. Odour occurs only for a short
while after the seat ring lid is lifted up. This is normal with natural ventila-
tion. If continuous odour problems persist:
1. make sure that the ventilation pipe is routed from the top to the roof
without any bends and extends over the roof ridge. If the ventilation
pipe is not straight or does not extend over the roof ridge, you should
improve the ventilation of the Populett 200 model by installing the
Biolan Wind Fan (see Accessories on page FI-8). The ventilation can
also be improved by extending the ventilation pipe with a sewage
pipe Ø 110 mm.
2. make sure that the disc valve (part 6) in the seat top is open.
3.
make sure that the seep liquid removal system is operational: the
liquid coming out of the toilet is routed into the collecting tank. As
required, check the fall of pipe and clean up the liquid pipe (part 14).
4. make sure that the bulking material used is Biolan Compost and Toi-
let Bulking Material (see Accessories on page EN-8). If, for example,
a mixture of peat and wood shavings or other bulking material of fine
texture is used, the mass may be packed too tightly.
5.
make sure that a sufficient amount of Biolan Compost and Toilet
Bulking Material, about 0.2-0.5 litres, has been applied after each
use.
6. repeat the spraying at intervals of at least two-three days to extermi-
nate the new generations emerging from eggs and maggots. Spray
insecticide also inside the toilet unit and close the lid. Repeat the
spraying until flying insects can no longer be spotted.
3.2 Using cover soil
By cover soil we mean the semi-mature compost mass. At this stage,
the toilet waste has already decomposed. Harder wood matter has not
decomposed yet: thus the semi-mature compost soil has a rough tex
-
ture and look. The cover soil may still contain substances that prevent
growth. This means it must not be used as substrate but as cover on
top of the soil.
3.3 Maturing cover soil to compost
soil
If you continue to compost the cover soil, it will mature into proper com
-
post soil. For post-composting, it is advisable to use the replacement
tank, available for the Populett as an option, or a composter with cover,
such as e.g. the Biolan Garden Composter or the Biolan Stone Com-
poster (see Accessories on page EN-8) to prevent rainwater from flush
-
ing away the water-soluble nutrients. In a couple of months, the compost
matures into compost soil of a dark brown colour and aggregate struc-
ture, from which source substances, except for bigger wood splinters,
can no longer be distinguished.
3.4 Testing the maturity of the
compost soil at home
The maturity of the compost can easily be tested at home by sprouting
garden cress.
1.
Fill two pots: one with compost and the other one with growth peat.
2.
Sow the seeds, cover with plastic and place the pots in a sunny place.
3. In two weeks you can judge from the result whether the compost is
sufficiently mature or not. If the plants sprout significantly better in
the pot with peat, the compost still contains substances that impede
growth.
The compost is not mature, if the seeds germinate, but the plants soon
wither away.
Disposal of the product
The raw materials used are presented in the component list (see page 4).
Dispose of each part as prescribed. Always follow the regional and collect-
ing-point-specific instructions.
To energy-from-waste process or recycling of
plastic:
EPDM = ethylene propylene
PE = polyethylene
PP = polypropylene
To energy-from-waste process:
PU = polyurethane
To collection of metal:
RST = stainless steel
ST Zn = hot-galvanised steel
To recycling of paper:
Paper
To mixed waste:
PVC = polyvinyl chloride
4.2 Insects or maggots
The most common flies appearing in dry toilets are small fungus gnats,
fruit flies etc. Using a fly net does not prevent these tiny flies from enter
-
ing the compost. The fly maggots are light in colour, and can try to get
out of the toilet unit via the seat part, if the conditions inside the toilet are
too hot for them.
The presence of flies in the compost often indicates that the compost
mass is too wet.
1. make sure that the bulking material used is Biolan Compost and Toi-
let Bulking Material (see Accessories on page EN-6). Some beddings
(e.g. fresh chips of deciduous trees) attract flies to the compost. The
pine bark used in the Biolan Compost and Toilet Bulking Material,
however, acts as a repellent.
2. add a thick layer of bulking material on top of the compost.
3.
do away with any flying insects in the toilet space using pyrethrin-
based spray. Consult your local garden centre to select a suitable
product. Repeat the spraying at intervals of at least two-three days to
exterminate the new generations emerging from eggs and maggots.
Spray insecticide also inside the toilet unit and close the lid. Repeat
the spraying until flying insects can no longer be spotted.
Please consult your local waste advisor for regulations on
composting.
