“…The dewatering efficiency is affected by the retention time of sludge in the reed bed system, what is more, the dry matter content increases with the depth of deposited sludge. Dewatering of sewage sludge in reed beds is equally efficient and much cheaper than the conventional mechanical methods, which additionally consume a large amount of energy and need chemicals to improve the efficiency of the process [12].…”

“…Despite the emission of greenhouse gases, which is inevitable, due to the mineralization process, wetland systems are still an environmental friendly technology. If a system is well functioning, the presence of reeds reduces the amount of methane produced to a minimum, and also supports oxidation of methane by aerobic methanotrophic bacteria [12].…”

“…Moreover, the time needed to start up the object can be a downside of this technology. The construction of the system is simple but requires a proper design and precision of workmanship, their lack may be the reason for the incorrect operation of the system [12].…”

Beach wrack is a unique issue. It is both an ecological problem for the eutrophicated reservoirs such as the Baltic Sea and the social one associated with nuisance for inhabitants and tourists visiting seaside resorts. This generates a problem for the institutions responsible for beach management (local authorities). Nowadays local authorities generally leave cleaning the beach to local companies and it is not known how the beach wrack material is utilized. According to the current trend, the nuisance of beach wrack should be turned into a resource that will bring benefits. In order to understand what beach wrack really is, it is necessary to establish a specific definition. The material washed out by the sea contains not only the natural substances of organic origin, but also human products: plastics, glass or metals, which in many cases forces to pre-select before using the technology. Good treatment of material the quantities of which are undefined and the occurrence is variable, constitutes a real challenge. The beach wrack processing on reed bed system, so far used mainly for the treatment of sewage sludge, seems to be a good idea. It is an innovative technology that is expected to have similar results as for the processing of sewage sludge from wastewater treatment, i.e. a high nutrient fertilizer. In accordance with European Union recommendations, the possible use of beach wrack as a fertilizer in agriculture or enrichment of compost, will close the circulation of organic matter in environment, thus entering the reed bed system into a circular economy. Many aspects related to the reed bed system favor the use of this technology in the practical processing of marine organic waste.

In this work, we assessed the drying and composting effectiveness of helminth eggs removal from sewage sludge of a lagoon wastewater treatment plant located in Chichaoua city. The composting was run after mixing sludge with green waste in different proportions: M1 (½ sludge + ½ green waste), M2 ([Formula: see text] sludge + [Formula: see text] green waste), and M3 ([Formula: see text] sludge + [Formula: see text] green waste) for 105 days. The analysis of the dewatered sewage sludge showed a load of 8-24 helminth eggs/g of fresh matter identified as Ascaris spp. eggs (5-19 eggs/g) followed by Toxocara spp. (0.2 to 2.4 eggs/g); Hookworm spp. and Capillaria spp. (0.4-1 egg/g); Trichuris spp., Taenia spp., and Shistosoma spp. (< 1 egg/g) in the untreated sludge. After 105 days of treatment by composting, we noted a total reduction of helminth eggs in the order of 97.5, 97.83, and 98.37% for mixtures M1, M2, and M3, respectively. The Ascaris spp. eggs were reduced by 98% for M1 and M3 treatments and by 97% for M Treatment. Toxocara spp., Hookworm spp., Trichuris spp., Capillaria spp., and Shistosoma spp. eggs were totally eliminated (100% decrease) and the Taenia spp. was absent from the first stage of composting. These results confirm the effectiveness of both dehydrating and composting processes on the removal of helminth eggs.
