“…This can also be related to the presence of a significant number of biogenic compounds which contribute to the growth activity of cress. Studies, reporting that increased N content in industrial effluents is beneficial for plant growth [32,33]. Our results agree with other studies being conducted on toxicity of industrial effluents using lettuce and other seeds as bioindicators.…”

Ocena toksyczności ścieków z przemysłu mięsnego oczyszczonych w procesie beztlenowymMajor pollutant components of meat processing wastewater are biodegradable organic compounds, fats and proteins in both particulate and dissolved forms. Because of the possible pollution of water sources, the efficient disposal of effluent from meat plants is important. The treatment of industrial wastewater is a highly complex process that generally involves factors associated with load fluctuations and high concentrations of organic matter. Toxic effects on aquatic organisms and plants may be caused by numerous nitrogen compounds, as well as detergents and antibiotics, in the meat industry wastewater. The aim of the research was to determine the toxicity of anaerobic treated meat industry wastewaters. The level of toxicity was determined with algae growth inhibition test and Lepidium test. The values of ErC50 (0÷96) and EbC50 of indicators were 18.4 and 8.6% respectively. TU value for ErC50 was 5.51 which meant acute toxicity of wastewater. The value of TU for EbC50 was 11.62 (high toxicity of wastewater). The values of indicators RSG (relative seed germination), RRG (relative root growth) and GI (germination index) were 92, 19.5 and 17.62% respectively. Treatment efficiency meat industry wastewater during fermentation process was very high. The COD and BOD removal efficiency were on 82.3 and 80% respectively. Effluent from ASBR reactor had following parameters: COD -206 mg O2/dm 3 and BOD -130 mg/dm 3 . TOC value after anaerobic process was 75 mg C/dm 3 (78.1%). The concentration of ether extract and proteins were 188 and 74 mg/dm 3 respectively. Generated biogas in the methane fermentation process of wastewater from meat industry plants was characterized by a high methane content (77.5% vol.). Carbon dioxide and the ballast in the analyzed biogas were 20 and 2.5% respectively. In order to enrich biomass with methane by removal of CO2 from its content, the gas generated in the anaerobic process was subjected to the processes of chemisorption and adsorption on the granulated active carbons and molecular sieve. Purification the raw biogas by a molecular sieve has contributed to the increase of methane in enriched from 77.5 to 92.6% and the removal of CO2 from 20 to 5.7%. Due to poor quality and its high toxicity, effluent from ASBR reactor can not to be discharged into natural water. In the future it is suggested to incorporate RO or UF into the technological system in order to posttreatment the wastewater.

“…This is in contrast to the expectation that the leachate EC would peak earlier from sandy-textured (SS and Cf) soils than from a finer-textured soil (Se). The EC trend in the Ia may be due to a high adsorption of cations from the effluent causing the soil solution to become more dilute and hence give relatively lower EC values in the leachate as reported by Bame et al (2014). The EC of the leachate did not show a sharp decline or rise with successive PVs showing that the ions in the leachate attained a gradual equilibrium in the SS, Cf and Se (Fig.…”

“…6). Less P in the leachate than in the applied effluent for Ia (up-flow) could be due to the retention of P by iron and aluminium oxides and hydroxides in this soil (Bame et al, 2014). The P leaching ratio at the beginning of the effluent application was < 1 due to the displacement of pre-event solution by the effluent diluting the P concentration in the leachate.…”

“…These characteristics could promote greater interaction between the Se and Ia soils and the incoming effluent, with subsequent depletion of nitrate through denitrification, a parameter not measured in this study. Sandy-textured soils (SS and Cf), on the other hand, allow relatively high leaching of nitrate due to their higher saturated hydraulic conductivity (Table 1) and lower cation exchange capacity (Bame et al, 2014). The effect of flow rate on nitrate leaching (Fig.…”

Leaching of nitrogen and phosphorus from soil columns during application of anaerobic baffled reactor effluent was evaluated. The soils used were from Inanda (Ia), Cartref (Cf), and Sepane (Se) forms, and a silica sand (SS). Each was packed into duplicate columns (103 mm internal diameter; 200 mm length), four each for up-flow and down-flow leaching. Effluent was delivered continuously for 6, 8 and 35 days at high (32 mm·h ) rates, respectively. At each flow rate, 9 pore volumes were collected. Leachates were analysed for pH, electrical conductivity (EC), nitrate and phosphate. Leachate pH from all soils was lower than the original effluent (6.4). Leachate EC varied between 0.5 and 0.9 dS·m -1 compared to the effluent EC of 0.84 dS· m -1. At high flow rate, the amount of nitrogen leached was similar from all soils. At low and medium rates, more nitrogen was leached from the coarser-textured SS and Cf than the finer-textured Ia and Se, at both flow directions. Flow direction had a greater effect on nitrogen leaching from finer-than coarser-textured soils. Phosphorus concentrations were higher than the original effluent at medium and high flow rates indicating that the soils were a source of phosphorus. At low flow rate, phosphorus concentrations were much lower than the original effluent, indicating soil retention. Phosphorus leaching was greater from coarser-than finer-textured soils in the up-flow columns, but the opposite occurred in the down-flow columns.

“…Regarding the nutritional development of plants, the effluent presented agronomically desirable characteristics such as the presence of nitrogen (N), phosphorus (P), and potassium (K) macronutrients (Bame et al, 2014;Grundmann & Maab, 2017, Pereira et al, 2011Singh et al, 2010;Bourazanis et al, 2016) Regarding implications for agricultural reuse, several aspects have been widely evaluated and discussed. One of the relevant aspects, of a sanitary nature, is related to the recommended microbiological guidelines for the use of sewage in agriculture (Pedrero et al, 2012;US EPA, 2012), where concerns are concentrated on the health of the farmer and consumers of agricultural products.…”

This study was conducted to evaluate the nutritional status of table beet plants cultivated in a greenhouse irrigated with treated dairy effluent at different irrigation depths. The experimental design used was a randomized block in a 3 x 3 + 1 factorial arrangement with four replications and conducted in a greenhouse. The treatments consisted of three types of water sources and three irrigation depths applied by drip irrigation: anaerobic effluent; anaerobic/aerobic effluent; tap water, and irrigation for replenishment 50; 100 and 150% of the crop evapotranspiration (ETc). All these treatments were applied in combination with 50% of the recommended nitrogen fertilization for the table beet cultivation. A control treatment was irrigated with tap water with irrigation depth equal to 100% ETc and received the complete dose (100%) of mineral nitrogen fertilizer. Table beet seedlings were arranged in 40 fiberglass boxes with a base area of 1 m 2 . Table beets were harvested 72 days after transplanting (DAT) when the leaves and roots were analyzed. Irrigation with wastewater promoted appropriate levels of macronutrients, distributed between the leaves and roots. The sodium was increased significantly in the leaves and roots of table beets in effluent treatments at increasing irrigation depths, which was antagonistic to the absorption of potassium.
