Maintenance
The microbial growth formed on the filter element collects nutrients from the gray water
flowing through the filter elements. The biological purification process is sensitive to
poisoning i.e., drugs, chemicals for sewage stops, chlorine, large amounts of antibacterial
detergents, solutions, oil, paint, or other problematic waste. This is because all of this kill the
microbe function of the bio filter.
One should also avoid directing nutritious substances, such as milk and fats to the bio filter,
nutritious substances should be composted.
Keep in mind that large amounts of greasy dishwashing water may cause the filter elements
to be cleaned more often.
If the water flow through the filter elements deteriorates significantly, the filter elements
should be cleaned more often. The clearest sign that the filter elements need to be cleaned
is that the upper part of the filter elements (10 highest cm) is dirty. Contamination of the
upper parts of the filter elements may also be due to a temporarily large amount of
wastewater or to a stop in the discharge site after the filter.
Location of the carpets from the inlet to the outgoing water:
2 green, 2 blue and last 4 grey filters.
Filter elements are absorbed and cleaned once a year by shaking them out above a
compost.
The residual sludge should be composted in a latrine compost.
