In this work, performance of cow dung (CD) reinforced poly(lactic acid) (PLA) biocomposites was investigated for the potential use in load bearing application. CD of average 4 mm size was blended with PLA at different CD ratios (0–50 wt%) and their effects on the biocomposite properties were studied. The results showed an improvement in the flexural properties, while the tensile and impact strength dropped by 20 and 28% with the addition of 50% CD. The decline in the tensile and impact strength was due to micro-cracking and voids formation at higher CD content. Also, the incorporation of CD slightly decreased the thermal stability of the biocomposite. However, dynamic mechanical properties of the biocomposites generally improved. SEM analysis of tensile and impact fractured surfaces indicated that the CD had a reasonable adhesion with matrix. Moreover, the SEM micrographs of soil burial studies showed an accelerated degradation of higher CD wt% biocomposites. 相似文献

In the current study, the chemistry of fresh and stored rainwater of Thar Desert, Pakistan, was estimated during two consecutive monsoon periods. The present research deals with the variation in physicochemical parameters, total arsenic (Ast), inorganic arsenic species (Asi, AsV, AsIII), and fluoride (F?) in stored rainwater (SRW) at different time intervals (1 week to 3 months). The pH of fresh rainwater (FRW) samples showed slightly acidic to neutral in nature (6.08–7.06) which were inconsistent with the reference pH value (5.6) of rainwater. The resulted data indicated that Ast and F? levels in SRW were enhanced with time duration. The levels of Ast and F? in SRW after different time intervals were found in the range of 194–683 μg/L and 10–35.4 mg/L, respectively. The values of Ast and F? were 20–70 and 7–24 times higher than those of WHO permissible limits, 10 μg/L and 1.5 mg/L, respectively. The AsIII was dominant species in SRW, which corresponds to >60 % of Asi. The characteristics of the SRW revealed an unacceptable quality to consume for drinking and agricultural purposes in the studied area. 相似文献

The recycling of sewage sludge on agriculture land represents an alternative, advantageous, disposal of this waste material.
The aim of the present study was to evaluate the feasibility of using industrial sewage sludge, produced in Pakistan, as a
fertiliser. Agricultural soil amended with 25% (w/w) sewage sludge with or without lime treatment was used for growing a variety
of sorghum (PARC-SS-1). The mobility of the heavy metals (HMs) (Cd, Cu, Cr, Ni, Pb and Zn) and metalloid (As) in the untreated
industrial waste water sewage sludge (UIWS) samples were assessed by applying a modified BCR (Community Bureau of Reference)
sequential extraction procedure. The single extraction procedure comprised of the application of mild extractant (CaCl2) and water for the estimation of the proportion of easily soluble metal fractions. The precision and accuracy of BCR was
evaluated by using a certified reference material of soil amended with sewage sludge BCR 483. The plant available metal contents,
as extracted by the deionised water and 0.01 M CaCl2 solution and exchangeable fraction of BCR sequential, decreased with lime application in the range of 10–44% for As, Cr,
Ni, Pb and Zn, except in the cases of Cd and Cu, where their mobility was increased by 10% and 24%, respectively. Sludge amendment
enhanced the dry weight yield of sorghum and the increase was more obvious after liming up to 25%. The uptake of HMs were
lower in test samples (3.2–21.8%), except for Cu and Cd, which was higher (4%), while they were below the permissible limit
of these metals. The present experiment demonstrates that liming was important in factors facilitating the growth of sorghum
in sludge-amended soil. 相似文献

Produced water is a significant waste stream generated in association with oil and gas production. It contains high concentrations of hydrocarbon constituents and different salts. In this study, a membrane sequencing batch reactor (MSBR) was used to treat synthetic and real produced water. The MSBR was evaluated in terms of biodegradation of hydrocarbons in the synthetic produced water with various organic loading rates (OLR) (0.281, 0.563, 1.124, 2.248, and 3.372 kg COD/(m3 day)), cycle time (12, 24, and 48 h), and membrane performance. The effects of salt concentrations at different total dissolved solids (TDS) (35,000, 50,000, 100,000, 150,000, 200,000, and 250,000 mg/L) on biological treatment of the pollutants in the synthetic and real wastewater were studied. At an OLR of 1.124 kg COD/(m3 day), an HRT of 48 h and TDS of 35,000 mg/L, removal efficiencies of 97.5%, 97.2%, and 98.9% of COD, total organic carbon (TOC), and oil and grease (O&G), respectively were achieved. For the real produced water, removal rates of 86.2%, 90.8%, and 90% were obtained for the same conditions. However, with increasing salt content, the COD-removal efficiencies of the synthetic and real produced water were reduced to 90.4% and 17.7%, respectively at the highest TDS. 相似文献
