    Opis:
    The aim of this study is to evaluate the potential of Citrullus lanatus seeds (a natural coagulant) also known as Watermelon seeds in treating Yamuna River Water. The problem of water scarcity in developing nations requires an economical and feasible water treatment process like coagulation. The watermelon seeds were analyzed on different physicochemical water treatment parameters. To understand the efficiency of the coagulant; a jar test was conducted by varying dosage, mixing speed, pH, and temperature. At an optimum coagulant dosage of 250 mg/L, pH of 7, stirring speed of 100 rpm, and temperature of 30 °C, the maximum turbidity removal of 81% was observed. The study concludes that the Citrullus lanatus seeds can be used as an effective natural coagulant for water treatment in developing countries.

    Opis:
    This study includes two parts; the first one, concerns evaluation of the physicochemical and microbiological quality of the urban wastewater of the city of Fez, through a space-time dynamics. In turn, the second part deals with the contribution to the treatment of these effluents, by a new biodegradable reagent in the process of physicochemical treatment (coagulation flocculation). For this purpose, the sampling of urban wastewater was carried out 4 months (September, December, February and June 2019), at a rate of two samplings per period on 4 specific sites along the river Fez, the degree of contamination of which differs from one site to another, according to space and time. The diagnostic of these stations showed a high level of pollution that is difficult to biodegrade. Indeed, this pollution can cause negative effects not only on the environment but also on human’s health. In order to take long-term action against the low quality of water and to replace certain inorganic coagulants, alternative processes for water treatment using cactus powder were set up. The characterization of results showed that the urban effluent has a high load in terms of electrical conductivity (EC), dissolved oxygen, chemical oxygen demand (COD), as well as concentrations of faecal coliforms, streptococci and staphylococci. In addition, the purifying power revealed that the removal rate of COD reaches maximum values of 38% and 58% forlimeand the mixture of lime with cactus powder, respectively.

    Opis:
    The objective of the study was to optimize the operation of the municipal wastewater treatment plant (WWTP) of the Sicaya district with Hydrocotyle ranunculoides. The relative growth rate of the macrophyte was determined, in addition to the relationship between the population growth area and the final weight according to the number of days elapsed. Medium fences were implemented and the tributary and effluent of the WWTP were characterized physicochemically and microbiologically. The results of the characterization corresponding to the tributary were as follows: 616 mg of TSS/L, 109.2 mg of BOD5/L, 305.4 mg of COD/L, 30.3 mg of oils and fats/L and 3 500 000 NMP of thermotolerant coliforms/100 ml. Owing to the implementation of two medium grids, large suspended solids were retained. The highest efficiency of COD removal with respect to the growth area of H. ranunculoides (2 226.96 m2) was 81.53%. While the efficiency of removal of thermotolerant coliforms was 79.2% at a water temperature of 12.32°C . Using the operational optimization model in the WWTP with H. ranunculoides, an area of 3 291.67 m2 of macrophyte population growth was achieved with a removal efficiency of 93.71% COD and an area of 3 591.67m2 to remove 79.95% of the thermotolerant coliforms at a temperature of 13°C.

    Opis:
    The objective of this study was to investigate the effects of modification by heat-moisture treatment (HMT) combined with microwave pre- and post-treatment (MW) on the physicochemical, structural and digestive properties of potato starch. The light microscopy, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) were used to determine the structural properties of starch. FT-IR and XRD spectra implied that MW and HMT destroyed the double helices and crystalline structure of potato starch. The relative crystallinity of modified starch granules (15.17–18.17%) was lower than that of native starch (19.39%). In the case of physicochemical properties, the modified starches had higher pasting temperature (68.8–93.0oC) and setback viscosity (807–3168 cP), but lower peak viscosity (1315–3662 cP) and breakdown viscosity (17.3–78.3 cP) than that of native potato starch, which were 68.5oC, 496 cP, 6598 cP and 2526 cP, respectively. The HMT and MW modifications significantly increased the content of slowly digestible starch and resistant starch. The resistant starch content of starch obtained by HMT combined with MW post-treatment was significantly higher than that of starch obtained by HMT combined with MW pre-treatment and single HMT. These results may promote good understanding of the effects of HMT combined with MW pre- and post-treatment on physicochemical properties and digestibility of potato starch, and wide utilization of microwave and heat-moisture techniques in starch modification.

    Opis:
    The research aims to study the purification performance of a local and natural material as an input or as a biological filter for treating urban domestic wastewater. For this purpose, pozzolan was used as the biofiltration support that was provided from Beni Saf located in the North-West of Algeria. Tests were carried out with a specially modified pilot unit (TE900) for wastewater treatment over a period of four months. To assess the efficiency of the treatment, two main parameters have been focused on - the height of the sprinkler filter (40 cm and 80 cm) and the flow rate (10, 16, and 25 dm3∙h-1). Physicochemical and bacteriological analyses were carried out on raw wastewater and treated water. The obtained results show that the Beni Saf pozzolan-filled trickling filter eliminates a large fraction of the studied pollutants. The purification yields obtained are fairly encouraging; 98% for turbidity, 88% for suspended solids (SS), 94% for chemical oxygen demand (COD), and 98% for biological oxygen demand (BOD5 ). As for bacterial indicators, the formation of biofilms has significantly reduced bacterial activity with a percentage of over 80%. It can be concluded that the reduction of pollutant parameters clearly indicates the effectiveness of the treatment by this ecological process. Therefore, the use of local and natural materials for wastewater treatment can be a promising alternative based on sustainable environmental technologies and development.

    Opis:
    In order to use the purified wastewater for the irrigation of a golf course in the Taghazout area (Southwestern of Morocco), this study was conducted to evaluate the physicochemical and bacteriological quality of the treated wastewater in the new Aourir plant (Activated Sludge technology). In order to achieve these objectives, three types of water were analyzed: raw water (RW), biologically treated water (BTW) and water treated by ultraviolet radiation (UV-TW). The physicochemical parameters analyzed were Temperature, pH, Electrical Conductivity (EC), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), five-day Biological Oxygen Demand (BOD5), Total Suspended Solids (SS), Nitrate (NO3), and Orthophosphates (PO4). Otherwise, the analyzed biological parameters are Total Coliforms (TC), Fecal Coliforms (FC), Escherichia coli (E. coli), and Fecal Streptococci (FS). The physicochemical parameters showed that temperature is always lower than 30°C, the pH is close to neutrality and a strong fluctuation of the high electrical conductivity (2700 μS/cm) occurs in UV-TW. At all stages of wastewater treatment, COD, BOD5, SS, NO3 and PO4 were below the limit values recommended by Moroccan standards. The bacteriological results showed a high level of bacterial contamination in RW and BTW, but in UV-TW the loads did not exceed 3 log10. The average loads of TC, FC, E. coli and FC in UV-TW were 2.13, 1.67, 1.77, and 2 (log10 CFU/100ml) respectively. Activated sludge treatment combined with UV has demonstrated sufficient quality to reuse treated water in irrigation; however, the UV treatment requires control to avoid any effect on the microbiological and physicochemical quality of green spaces and groundwater.

    Opis:
    The sewage sludge recycling as an agricultural land resource has received a great deal of attention worldwide. This practice has highly increased because of ever-increasing municipal wastewater production and the awareness of its fertilizing potential as amendment resources. However, there is a concern about land spreading linked mainly to health associated risks due to the presence of diverse pollutants. Thus, sewage spreading management is a key factor the guarantees benefits and avoids risks. The present work aimed to investigate the benefits and risks of sewage sludge (SS) application on agricultural land. To this end, physicochemical main parameters and bacteriological indicators, fecal coliform (FC) and fecal streptococcus (FS), of the sewage sludge generated form WWTP of Skhirat, Morocco, were performed during the period 2018–2019. The obtained results of physicochemical parameters reveal high concentration of organic matter in SS, which reach 96.3 mg/l, and in nutrients. Indeed, total Kjeldahl nitrogen TKN reaches a maximum of 3791 mg/l, potassium K+ reaches 58.71 mg/l. In addition, the average content of FC and FS are around 5.40 CFU/ml and 5.85 CFU/ml, respectively, whereas total phosphorus reaches 508.25 mg/l. In addition, concentrations of micronutrients such as Cl-, SO42-, Ca2+, Mg2+, and Na+ were high, which is interesting and could benefit for both soils and plant. Furthermore, this sewage sludge contains high concentration of heavy metals, mainly zinc and copper which could limit reuse in land spreading. The obtained results were compared to the applied standards and directives established within the framework of the agricultural spreading.

    Opis:
    The results of a pot experiment on soil application of sewage sludge samples (at the rate of 200 g DM • pot-1) from 19 sewage treatment plants localized in region of the Green Lungs of Poland in three areas: the Great Masurian Lakes, Iława Ostróda Lake District and Łyna River Basin, are discussed in the paper. The sewage treatment plants had different capacities, received different shares of industrial sewage water and used different technologies of sewage sludge dewatering. In the pot experiment the following five vegetable crops were grown (without winter break): root celery, lettuce, small radish, Swiss chard and spinach. Before planting the first plant (celery) and after harvesting the last plant in the rotation (spinach), physical and chemical properties of the soil were studied in order to determine if the amendment of soil with sewage sludge could pose any environmental risk to the growth of vegetable crops. It was found that most of the applied samples of sewage sludge did not produce adverse effects on the determined parameters. In many cases, the content of organic carbon increased soil retention properties were improved under the effect of sewage sludge. Sewage sludge form Zalewo, because of its high content of chromium, was implied as being hazardous for growing plants, as it could result in soil and plant contamination. When sewage sludge from Olsztyn, Olsztynek and Spychowo was applied to soil, zinc contamination occurred.
    W pracy przedstawiono wyniki doświadczenia wazonowego z zastosowaniem osadów ściekowych, w jednakowej dawce 200 g s.m.-wazon'1, pobranych z 19 oczyszczalni ścieków zlokalizowanych na obszarze tzw. Zielonych Płuc Polski w trzech regionach geograficznych: Wielkich Jezior Mazurskich, Pojezierza Ostródzko-Iławskiego i zlewni rzeki Łyny. Oczyszczalnie różniły się wielkością, udziałem przemysłowych ścieków i technologią odwadniania osadów, z czego wynikały różnice w składzie chemicznym tych odpadów organicznych. W doświadczeniu uprawiaono kolejno po sobie (bez przerwy zimowej) pięć roślin warzywnych, jak: seler korzeniowy, sałata, rzodkiewka, burak liściowy i szpinak. Przed założeniem doświadczenia i po zbiorze każdej rośliny badano podstawowe właściwości fizyczne i chemiczne gleby w celu określenia, czy nawożenie osadami ściekowymi może powodować zagrożenie skażenia środowiska glebowego w warunkach uprawy roślin warzywnych. Wykazano, że w większości przypadków zastosowanie osadów ściekowych nie wpłynęło ujemnie na badane parametry gleby. Zawartość węgla organicznego pod wpływem nawożenia osadami w wielu przypadkach wzrosła i nastąpiła poprawa właściwości retencyjnych gleb. Stosowanie osadów ściekowych z Zalewa – ze względu na wysoką zawartość chromu - może spowodować zagrożenie dla środowiska glebowego. W przypadku stosowania doglebowego osadów ze Spychowa, Olsztyna i Olsztynka stwierdzono w glebach ponadnormatywne stężenie cynku.

    Opis:
    Slurry, due to high microbiological contamination, requires hygienization before spreading. The agricultural usage of treated slurry has to guarantee biosafety. Therefore, constant monitoring of the slurry treatment process should be conducted. The use of Filter-Sandwich carriers seems to be a prospective solution. The aim of the research was to test whether Filter-Sandwich carriers influence the survivability of microorganisms during the slurry hygienization process and hence, whether they are safe for the environment. Raw cattle and swine slurry with different dry matter content was the research material. Salmonella Senftenberg W775 rods were introduced directly into the slurry and into the carriers placed in the liquid excrements stored at 4 and 20 °C, and underwent anaerobic digestion at 35 °C. The number of tested bacteria obtained from the slurry and carriers was determined using the MPN method with proper microbiological media. The values of physicochemical parameters of the raw and treated slurry were determined, both for the carriers and for slurry only. Biosafety control was also conducted for the carriers in slurry containers. The differences in the theoretical survivability between Salmonella Senftenberg W775 re-isolated from the slurry and the carriers, and in the values of the selected physicochemical parameters obtained at the end of the process, were not statistically significant. The re-contamination of the sterile slurry caused by the bacteria in the carrier was not observed after placement of the carrier with inoculated material. The conducted research proves the usefulness of Filter-Sandwich carriers for continuous hygienization monitoring of the slurry treatment process. This refers not only to the semi-technical scale, but also to the full-scale process.

    Opis:
    Rozbudowana struktura drugo- i trzeciorzędowa białek serwatkowych: α-la, β-lg, BSA i immunoglobulin, sprawia, że są podatne na procesy denaturacyjne wywoływane czynnikami chemicznymi lub fizycznymi (temperatura czy wysokie ciśnienia). Procesy termiczne, szeroko stosowane w przemyśle mleczarskim, powodują denaturację, zmianę właściwości fizyko-chemicznych i żywieniowych białek serwatkowych. Poznanie tych zmian i technik, którymi można je obserwować jest istotne ze względów badawczych i żywieniowych. W artykule przedstawiono przegląd kilku technik wykorzystujących zmianę właściwości immunore-aktywnych, termodynamicznych (temperatura i entalpia denaturacji, energia aktywacji), fizykochemicznych pozwalających lepiej poznać proces denaturacji tych białek.
    Whey proteins: α-la, β-lg, BSA and immunoglobulins due to their complex secondary and tertiary structures undergo denaturation caused by either chemical or physical factors (temperature, high pressure). Thermal processes - commonly employed in the dairy factory - cause denaturation and change physical, chemical and nutritional properties of whey proteins. This paper reviews different techniques used for monitoring the protein changes important regarding research and nutritional aspects.
