Qualitative Characteristics

In this study, qualitative characteristics of the sludge produced in Hamadan wastewater treatment plant and the feasibility of its application in agricultural lands were investigated. Samples were taken from the primary and secondary sludge and indices such as VS/TS, PH, TKN, COD, TKN, SOUR, Na, Ca, SAR, heavy metals and biological properties (the mean fecal coliform count and the number of parasitic eggs) were measured. The results were compared with the United States Environmental Protection Agency (US EPA) standards (40 FCR-503). The results showed that the VS/TS ratio of the raw sludge was 0.8, 0.55, and 0.55 and that of the secondary sludge was 0.65, 0.28, and 0.32 for fall, winter, and summer, respectively. The average concentration of COD, TKN, SOUR, Na, and Ca for the initial sludge was 51283, 107, 0.50, 609, and 952 and for secondary sludge, it was 35595, 81, 4.90, 306, and 493 mg/L, respectively. The MPN for primary and secondary sludge was determined to be 19.83 × 106 and 186 × 106 , respectively and the average number of parasite eggs in primary and secondary sludge was 7.05 and 7.2 in 4 g of dry solids. Entamoeba coli had the highest number of parasite. The results of this study showed that the highest concentration of heavy metals in the sludge was 21396 mg/kg. The values obtained for the above-mentioned indices and heavy metals were in standards range. The results of this study show that none of the primary and secondary sludge samples has been properly stabilized. The values obtained for biological characteristics of sludge were not in the standard range. Therefore, it was revealed that the use of sludge for agriculture needed more stabilization.

Abstract The study was conducted in two neighboring localities located in the northern county of Dolj, namely Murgasi and Bulzesti. The purpose of the study was twofold: namely, the study of heavy metal loading in order to identify possible pollution areas and to know the soil content of these localities in heavy metals in order to be able to give the verdict on the use of sludge from Craiova wastewater treatment plant as fertilizer on these soils. In order to determine the suitability of sewage sludge from the Craiova wastewater treatment plant as a fertilizer, physical and chemical properties and heavy metal content of the soils in these areas were analysed, as well as the chemical composition of sludge, according to Order 344/2004 of the Ministry of Environment and Water Management of Romania, respectively 13 physical and chemical parameters of the soils in these localities and the chemical composition of the sludge and respectively the quantity of heavy metals to be introduced annually into the soil by using it.

Increasing population growth, improve living standards and industrial development are factors which increase water consumption and waste production. Therefore, the use of treated wastewater in agriculture to overcome the problems of water scarcity, particularly in areas with water shortages, is important. In this study in addition to assessing the performance analysis of Genaveh hospital  wastewater treatment plant, The quality of the output of effluent of wastewater treatment plant  for use in agriculture based on Ayers water quality guidelines were assessed and its potential adverse effects on soil and plants were evaluated. In this study within six months physical and chemical parameters such as pH, EC, calcium, magnesium, sodium, chloride, nitrate, bicarbonate, TDS and heavy metals (iron, manganese, nickel, cadmium, cobalt, lead and zinc) in the output effluent were determined according to standard methods. According to the obtained results, the use of hospital effluent Genaveh in agriculture in term of concentration of sodium in terms of SAR, bicarbonate, chloride, Adsorbed sodium absorption ratio encountered with low to moderate limitation of electrical conductivity. Severe limitations in terms of nitrate nitrogen and heavy metals concentrations in the range are determined. In general results of this study indicate that to reuse the Genaveh hospital effluent in agriculture continuous monitoring of the output of effluent of wastewater treatment plant to meet environmental standards is essential.

Complex "Dikanivka" & "Bezludivka" wastewater treatment plant (WWTP, Kharkiv) is oneof the biggest in Ukraine. Mixture of industrial and domestic wastewater is treated on thestation. Great volume of sewage sludge has been produced and accumulated for forty years ofthe plant operation, Environment of the region has been affected rather seriously in result ofout-of-date sludge dewatering system exploitation and heaps of dewatered sludge on theterritory of the plant Environment stabilization in the area of sludge treatment is an urgentproblem of the region, Phytoremediation as a promising natural technology for the purpose isdiscussed in the article.Sewage sludge is rich in organic matter and nutrient elements (nitrogen and phosphates)therefore it could be applied for soil fertilization. On the other hand, due to high heavy metals(Cd, Ni, Cu, Cr) concentration in sludge, contamination with enteric parasites, pH less than5,5 there is restriction for sludge application in agricultural production,Willow (Salix spp,) is discussed as a plant for phytoremediation of the territory and forsubstratum properties melioration because of its availability to accumulate heavy metals,regulate concentration of nutrients, high biomass production and high environmentaltolerance.Experiment in situ has to be carried for the plant-remediater selection and for investigation ofsludge agricultural properties dynamic.
