The reuse of treated sewage for irrigation is considered as an important alternative water source in the new management strategy countries that face a severe deficiency resources such Middle East countries. organic material and fertilizing elements contained biosolids are essential maintaining soil fertility. However, both contain large diversity pathogens would be transmitted to environment infect human directly or indirectly. Therefore, those should reduced from before agriculture. This...
In this study, the zeta potential and z-average hydrodynamic diameter of zinc oxide (20 nm, 99.5% purity) were investigated as a function pH time. The nanoparticles readily formed aggregates could not be disintegrated to its primary size eventhough ultrasonication was applied. suspensions (25 mgL 100 mg/L) examined for electrophoretic mobility aggregation behaviour within range 3 11 time duration 60 minutes. particle measured by dynamic light scattering technique. application nanoparticle...
The present study was conducted to determine the feasibility of biodiesel production from candlenut oil using supercritical methanol (scMeOH) as a non-catalytic transesterification process. influence scMeOH process determined with varying pressure (85-145 bar), temperature (260-300 °C), (M : O) ratio (15 1-35 1), and reaction time (15-25 min). experimental conditions were designed central composite design (CCD) experiments, optimized response surface methodology (RSM). It found that...
Landfill leachate is a highly polluted and generated from water infiltration through solid waste produced domestically industrially. In this study, coagulation–flocculation process using combination of Polyaluminium chloride (PACl) as coagulant Dimocarpus longan seed powder (LSP) aid was used in treating landfill leachate. LSP has been tested the main with PACl. As coagulant, optimum dosage pH for PACl were 5 g/L 6, respectively, removal efficiencies 67.44%, 99.47%, 98% COD, SS, color,...
Elevated concentrations of heavy metals in groundwater cause many environmental problems. This paper reports adsorption behavior a green bioadsorbent (<italic>Trichoderma</italic> sp.) for the removal metal ions from industrial effluents.
A steam autoclave was used to sterilize bacteria in clinical solid waste order determine an alternative incineration technology management. The influence of contact time (0, 5, 15, 30 and 60 min) temperature (111 °C, 121 °C 131 °C) at automated saturated pressure investigated. Results showed that with increasing temperature, the number surviving decreased. optimum experimental conditions as measured by degree inactivation were for 15 minutes (min) Gram negative bacteria, min positive...
Fish oil was extracted and simultaneously collected into six fractions based on molecular weight the chain length of triglycerides in terms fatty acid constituents without splitting triglycerides, using supercritical carbon dioxide (SC-CO2) at optimized conditions 40 MPa, 65°C, a flow rate 3 mL min−1. In each type fractionation, first fraction (F1) rich saturated acids (SFA; 52.57 to 61.26%), followed by monounsaturated (MUFA; 22.17 23.22%) polyunsaturated (PUFA; (0.54 20.37%); sixth (F6)...
Cat’s whiskers ( Orthosiphon stamineus ) leaves extracts were prepared using supercritical CO 2 (SC‐CO with full factorial design to determine the optimum extraction parameters. Nine obtained by varying pressure, temperature, and time. The analysed FTIR, UV‐Vis, GC‐MS. Cytotoxicity of was evaluated on human (colorectal, breast, prostate) cancer normal fibroblast cells. Moderate pressure (31.1 MPa) temperature (60°C) recorded as conditions high yield (1.74%) extract (B2) at 60 min optimized...
The study probed into reducing faecal indicators and pathogenic bacteria, heavy metals β-lactam antibiotics, from four types of secondary effluents by bioaugmentation process, which was conducted with Bacillus subtilis strain at 45 °C. As a result, bacteria were reduced due to the effect thermal treatment process (45 °C), while removal antibiotics performed through functions bioaccumulation biodegradation processes B. subtilis. Faecal coliform met guidelines outlined WHO US EPA standards...
There is increasing concern to determine an alternative coagulant for treating industrial effluent with minimal environmental impact and operational cost. In this study, iron (II) sulphate heptahydrate (FeSO4·7H2O) waste, byproduct from a titanium oxide processing industry, was used as the removal of ammonia (NH3), chemical oxygen demand (COD), biochemical (BOD), suspended solid (SS) secondary rubber (SRPE). The highest percentage BOD, COD, SS, NH3 achieved approximately 97%, 99%, 98%, 95%,...
Summary The rapid depletion of diesel fuel, increasing energy demand, and environmental pollution concerns are worldwide interest in the production liquid biofuels. Biofuel (bio‐aviation biodiesel) is a potential plausible alternative to fuel substantially mitigate impact future demand. Non‐edible crop oil viewed as feedstock for biofuel owing massive demand edible food source. However, major limitation utilizing non‐edible biodiesel cost due high price feedstocks limited supply large‐scale...
