Cleaning
Sewage sludge contains bacteria and therefore it should be handled with caution.
The easiest way is to shake off the carpets above the compost, about 90% of the sludge will
then release. The knocked-out filters are then put back in the Biofilter, the 10% of sludge and
bacteria that remain ensure that the biological purification continues.
The sludge should be composted in a latrine compost for a normal 6 months to ensure full
degradation.
It should be avoided to clean the filter elements too often, as this reduces microbial growth,
which leads to a deterioration in purification results.
In winter, you can drain the biofilter if there is a risk of freezing that stops the flow, if you want
to be able to use the biofilter in winter, you should insulate it extra.
The biofilter can resist freezing temperatures normally well, nothing that breaks.
