Due to complex composition of leachate, the comprehensive leachate treatment methods have been not demonstrated. Moreover, the improper management of leachate can lead to many environmental problems. The aim of this study was application of Fenton process for decreasing the major pollutants of landfill leachate on Kermanshah city. The leachate was collected from Kermanshah landfill site and tre...

in the present research, effects of modified atmosphere packaging (map) includingthree gas combinations and two packaging films (low density polyethylene (ldpe) andpolypropylene (pp)) on postharvest quality and storage-life of 'elberta' peach wereevaluated. the study was conducted as a factorial experiment based on crd(completely randomized design) with three replicates for 9 weeks. f...

kiwifruit softening and the spread of gray mold on the fruit are the most important factors to be considered in kiwifruit storage life. in this study, the effect of calcium chloride (0, 1, 2, 4 and 8 percent) for 2, 4 and 8 minutes of dipping time were examined to improve the fruit physicochemical characteristics. following fruits being dried (24 hours), they were stored at 0.5oc and 85-90% rh ...

The aim of this study was to determine organic acids and individual sugars as well as carotenoids in fruit of Kumquat[Fortunella margarita (Lour.) Swingle] on different rootstocks.  On other hand, the purpose of this study was to identify the rootstock that could produce the highest amount of sugars. The content of individual sugars and organic acids in fruits were determined by HPLC, ...

in the present study, the treatment of tannery wastewater was performed by electrocoagulationmethod (ec) using aluminium and steel electrodes. response surface methodology (rsm) with three factors; current density (i), electrolysis time (t) and ph, with each factor at five levels, was used to optimize the factors for higher chemical oxygen demand (cod) and total suspended solids (tss) removal. ...

Phosphorus (P) is one of the most limiting nutrients for growth and development crops, important soil fertility managements, since it affects quality fruits. With hypothesis that different levels irrigation phosphorus fertilization interfere in physical physicochemical properties tomatoes, objective this experiment was to verify analyze behavior fruits’ responses. The conducted a greenhouse at ...

A study was conducted to assess the performance of anaerobic-aerobic treatment system of a local potato processing industry. The wastewater treatment plant (WWTP) consisted of primary treatment, upflow anaerobic sludge blanket (UASB), activated sludge process (ASP) and secondary clarifier. The study analyzed the physical, chemical and biochemical parameters of the influent (raw sewage) as well ...
