Crescimento do milheto (Pennisetum glaucum) irrigado com água residuária no Seridó Paraibano

The use of wastewater can be an irrigation alternative for millet, especially in areas with low availability of water, such as the Seridó Paraibano Region. The objective of this work was to evaluate the growth and production of millet irrigated with wastewater under a consortium with lab-lab beans. The experiment was conducted at the Caboré site, in the municipality of Frei Martinho-PB. The experimental design was a randomized complete block design with five plots (40, 60, 80, 100 and 120% of available water) in a consortium with lab-lab bean in the subplot. The treated wastewater came from the Sewage Treatment Plant of the municipality. The variables measured were: height of the plant; leaf area; number of leaves; diameters and SPAD (chlorophyll meter). There was a significant difference in relation to plant growth, leaf area and number of leaves. The stem diameter and SPAD had no significant effect, an average of 11.197 mm / plant and an average of 60.952 units were observed. The millet plants presented high number of leaves and high leaf area when applied to the irrigation blade of 300 mm of wastewater. The consortium of millet X-lab-lab beans did not interfere interfere with the growth of millet.

Concentration Levels

Most of the industrial sewage effluents used for irrigation contains heavy metals which cause toxicity to crop plants as the soils are able to accumulate heavy metal for many years. The vegetables grown for the present study were irrigated with treated wastewater brought from a nearby full-scale sewage treatment plant at different compositions along with tap water as a control. The concentration levels of the Cd, Co, Cu, Mn and Zn in the soil were found to below the toxic limits as prescribed in literature. Daily Intake Metals (DIM) values suggest that the consumption of plants grown in treated wastewater and tap water is nearly free of risks, as the dietary intake limits of Cu, Fe, Zn and Mn. The Enrichment Factor for the treated wastewater irrigated soil was found in order Zn> Ni> Pb> Cr> Cu> Co> Mn> Cd. Thus, treated wastewater can be effectively used for irrigation. This will have twofold significant environmental advantages: (1) helpful to reduce the groundwater usage for irrigation and (2) helpful to reduce the stress on surface water resources.

ABSTRACT Determining the effects of using wastewater as fertilizer on soil chemical properties allows a safe reuse of this effluent in agriculture. This study evaluated the effects of fertigation with tertiary treated wastewater (TTW) from the Janaúba sewage treatment plant on chemical properties of a Latosol (Oxisol) with banana crops of the Prata-Anã cultivar in the semiarid region of Brazil. A randomized complete block design with four replications was used to test four TTW rates (70%, 130%, 170%, and 200% of the limit of 150 kg ha-1 year-1 of Na that can be applied to the soil) and compare them to a control without TTW. Soil samples from the 0.0-0.2, 0.2-0.4, 0.4-0.6, and 0.6-0.8 m layers were collected at the end of the first crop cycle to evaluate soil chemical properties-pH, soil organic matter (SOM), P, K, Na, Ca, Mg, Al, potential acidity (H+Al), base saturation, B, Cu, Fe, Mn, Zn, remaining P, and electrical conductivity (EC). The use of TTW increases soil pH and decreases exchangeable Al content, thus, reduces the need for liming. However, Na contents increased faster than EC in the soil, indicating that the use of TTW tends to alter soil physical properties over time. The use of TTW had no effect on the soil OM, P, Ca, Mg, and micronutrients contents, potential acidity, and base saturation. The changes in soil chemical attributes observed at the end of the first crop cycle were not limiting to the banana crop.

Model Family

The process of designing and exploiting municipal sewage treatment plants has become much simpler and more efficient thanks to mathematical modeling. The ASM model family is able to simulate the operation of existing or designed objects in a satisfactory manner. The basic problem in Poland is the insufficient amount of data for simulations coming from plant monitoring. It is provided to create unstable model results with difficulties in calibration and validation. The aim of this article is to confirm how the amount of data and its completeness will affect the quality of the simulation performed in the ASM model. The study object is a sewage treatment plant located in Chicago in the USA. It is a sewage treatment plant operating with activated sludge technology, with regular monitoring of the quality of raw and treated wastewater. For modeling, a variant of the ASM model built into the BioWin 5.2 software was used.

Pharmaceutical Residues

Pharmaceutical residues, which pass naturally through the human body into sewage, are in many cases virtually unaffected by conventional wastewater treatment. Accumulated in the environment, however, they can significantly impact aquatic life. The present study indicates that many pharmaceutical residues found in wastewater can be removed with activated carbon in a cost-efficient system that delivers higher resource utilisation and security than other carbon systems. The experiment revealed a substantial separation of the analysed compounds, notwithstanding their relatively high solubility in water and dissimilar chemical structures. This implies that beds of activated carbon may be a competitive alternative to treatment with ozone. The effluent water used for the tests, performed over 20 months, originated from Stockholm's largest sewage treatment plant. Passing through a number of different filters with activated carbon removed 90–98% of the pharmaceutical residues from the water. This paper describes pilot-scale tests performed by IVL and the implications for an actual treatment plant that has to treat up to several thousand litres of wastewater per second. In addition, the advantages, disadvantages and costs of the method are discussed. This includes, for example, the clogging of carbon filters and the associated hydraulic capacity limits of the activated carbon.

Vegetative parameters of eight M3 (third mutant generation) lines of sesame were evaluated under rain fed condition. The seeds of the lines were sown alongside their respective controls using a randomized complete block design. The eight lines were generated from three parental stocks: NCRIBEN-04E (V1), NCRIBEN-01M (V2) and NCRIBEN-03L (V3). The three parental stocks were exposed to different doses of gamma irradiation from cobalt-60 source. 04E-550-G2-3 had the highest plant height (57.40) at the 6th week which was significantly different (P<0.05) from the three checks. 03L-450-G2-2 had the highest petiole length (12.45cm) which was significantly different (P<0.05) from the checks except check three (12.25cm) which was not significantly different (P>0.05). 03L-450-G1-2 had the highest number of leaves (91) and consequently highest number of branches (5.60). Although the number of leaves were significantly different (P<0.05) from Check three (54.60), there was no significant difference (P>0.05) between the number of branches and check three (5.40). The results obtained for vegetative parameters of M3 lines of sesame suggests that some of the genotypes could be used as potential parents for future breeding programmes aimed at improving sesame lines.

And Performance

In Agadir city, the reuse of treated wastewater for irrigation of green spaces has faced the problem of scaling of the pipes of these waters. This research paper aims at studying the phenomenon of scaling caused by the treated wastewater from the Mzar sewage treatment plant in the city of Agadir in south-west of Morocco. These waters are used in the irrigation of golf turf “Ocean”. The formation of solid deposits in the irrigation systems has decreased their lifetime, and consequently, a loss of load and performance is occurring. Thus, the sprinklers used in golf turf irrigation are plugged in the first weeks of the beginning of their operation. The wastewater used for the irrigation of the golf was analyzed at various points using physicochemical measurements: in the golf entry, at the tarpaulin and the exit of the sprinklers. The samples of treated wastewater and obtained scale were studied. The characterization of the scale samples formed in the passageways of the treated wastewaters has been performed by X-ray fluorescence spectrometry, X-ray diffraction, thermogravimetric analysis, differential thermal analysis and scanning electron microscopy. The results of the physicochemical analysis of the waters show that they are full of bicarbonates (653 mg/L), chloride (478 mg/L), nitrate (412 mg/L), sodium (425 mg/L) and in calcium (199 mg/L). Their pH is slightly alkaline. The analysis of the scale reveals that it is rich in calcium and phosphorus. It is formed of calcium carbonate (CaCO3), silica (SiO2), calcium silicate (Ca2SiO4), hydroxylapatite (Ca10P6O26H2), calcium carbonate-apatite(Ca10 (PO4) 6CO3) and silicate calcium and magnesium (Ca5MgSi3O12).

This study was conducted to evaluate the growth and yield of maize to compost, organomineral fertilizer, and mineral fertilizer at Iyaganku and Moniya farm sites in Ibadan, Oyo State, Nigeria. Treatments consisted of Organomineral fertilizer (A), Compost (B), Fresh compost (C), Mineral fertilizer (D = N.P.K. 15:15:15), and Control (E = no fertilizer). Experimental design was randomized complete block design replicated four times. Compost treatments (45 kgNha-1) were applied at one week before sowing while N.P.K. 15:15:15 fertilizer (300 Kg N ha-1) was applied two weeks after sowing. The growth and yield data collected were analyzed using Analysis of Variance (ANOVA) of GENSTAT Discovery software. Significant means were compared using Duncan Multiple Range Test (DMRT) at p = 0.05. The results of the analysis revealed no significant difference in the number of leaves and stem girth at 8 weeks after sowing (WAS) at Iyaganku. Tallest maize plants were recorded from plots treated with A and B. Also, treatments showed no significant difference in the dry weight (g/cob) of husked and unhusked maize at harvest. At Moniya, plots treated with A produced high number of leaves while lowest number of leaves were recorded from control plots and plots treated with B, C, and D. Similarly, no significant difference was observed in stem girth, plant height, dry weight (g/cob) of husked and unhusked maize at harvest between control plots, and plots treated with C, and D. Larger stem girths, tallest plants, dry weight (g/cob) of husked and unhusked maize at harvest were observed in plots treated with A and B. The results from Moniya farm site suggest that organomineral fertilizer and compost have the potential to enhance the growth and yield of maize in studied location.
