The disposal of sewage sludge from the wastewater purification process can be worked out without any energy, transportation and subsidiary expenditures. The mud formed during the sewage sludge handling procedure, is separated at regular intervals in a closed system, built exactly for this method, where we make humus out of it. 90-95% of the sewage sludge is water, so during the settling process, the water from the treated area is returned to the purification system. Later, the dried sediment becomes a very eutrophic humus, which is recyclable fpr gardening and landscaping.
