“…Therefore, in all countries of the European Union, there are directives for storage, stabilization and safe recycling. Before recycling, SS treatment usually involves disinfection, digestion, composting, and heat drying (Epstein 2003, Fytili and Zabaniotou 2008, Yang et al 2015, Cieślik et al 2015. During the disinfection process, the microflora of SS is changed.…”

Sewage sludge (SS) originating from communal wastewater is a hazardous material but have a potentially great nutritive value. Its disposal after treatment in agricultural lands can be a very economical and safe way of utilization once fast growing, high biomass, perennial plants of renewable energy production are cultivated. Szarvasi-1 energy grass (Elymus elongatus subsp. ponticus cv. Szarvasi-1), a good candidate for this application, was grown in hydroponics in order to assess its metal accumulation and tolerance under increasing SS amendments. The applied SS had a composition characteristic to SS from communal wastes and did not contain any toxic heavy metal contamination from industrial sludge in high concentration. Toxic effects was assessed in quarter strength Hoagland nutrient solution and only the two highest doses (12.5-18.75 g dm -3 ) caused decreases in root growth, shoot water content and length and stomatal conductance whereas shoot growth, root water content, chlorophyll concentration and the maximal quantum efficiency of photosystem II was unaffected. Shoot K, Ca, Mg, Mn, Zn and Cu content decreased but Na and Ni increased in the shoot compared to the unamended control. The nutritive effect was tested in 1/40 strength Hoagland solution and only the highest dose (12.5 g dm -3 ) decreased root growth and stomatal conductance significantly while lower doses (1.25-6.25 g dm -3 ) had a stimulative effect. Shoot K, Na, Fe and Ni increased and Ca, Mg, Mn, Zn and Cu decreased in this treatment. It was concluded that SS with low heavy metal content can be a potentially good fertilizer for high biomass non-food crops such as Szarvasi-1 energy grass.

“…However, by its origin -from the sewage treatment -the sludge concentrates many elements, which can pose risks to the environment and public health, such as heavy metals, pharmaceutical contaminants, polyaromatic hydrocarbons and pathogens (Andreoli et al, 2008, Cheng et al, 2012, Jones, Gardner, & Ellor, 2014, Cieslik, Namiesnik, & Konieczka, 2015, Gyawali, Sidhu, Ahmed, Jagals, & Toze, 2015, Rocha, Barés, & Braga, 2016.There is little information on the number and survival of pathogens in biosolids because of difficulties with detection methods, especially for viruses and protozoa (Sidhu & Toze, 2009).…”

ABSTRACT. For the use of sewage sludge, it is extremely important to consider the microbiological aspect of this byproduct that poses direct and indirect risks to public health as for its inadequate handling and use. This study aimed to quantify Giardia spp. cysts and Cryptosporidium spp. oocysts and infer their viability in sludge samples from two sewage treatment plants. The method used consisted of three successive centrifugations followed by immunofluorescence assay and staining with propidium iodide. Samples were 100% (14/14) positive for cysts and 57.1% (8/14) for oocysts, with higher concentrations and mean viability above 75%. The change in the treatment of activated sludge, from extended aeration to conventional system, caused no difference in the concentration and viability of (oo)cysts.
