in the current research, salicylic acid and putrescine treatments solutions each with 0, 0.5, 1, and 2 mm/l levels were sprayed on the ‘granny smith’ apple trees in three preharvest stages. the treatments were applied based on factorial experiment in the randomized complete block design. weight loss, fruit firmness, total soluble solids (tss), titratable acidity (ta), ph, tss/ta, peel color, an...

in order to evaluate the effect of water stress on fruit quality and quantity of some iranian melons, the experiment was set out in a split plot design with three replicates in research filed of university of zanjan in 2014. treatments consisted arrangement of three irrigation levels (starting irrigation at 100, 66 and 33 etc) and 11 genotypes of iranian melons (ʼkhatouniʻ, ʼkaliʻ, ʼorshangʻ, ʼ...

 Background: The refining process generates large volumes of wastewater containing a variety of chemical contaminants. The use of natural substitutes in treating wastewater which have fewer harmful effects is considered an effective step towards protecting the environment and sustaining the development of these industries. This study focused on the use of Moringa oleifera and alum at t...

A wide range of chemicals and dyes are being used in textile industry, and are often found in the wastewater produced. This study attempts to investigate the reduction of COD, TSS, and dye in effluents from the dyeing and washing unit of textile industry, using electrocoagulation process. The reactor is equipped with 10 iron electrodes, connected to a direct current (DC) source in a monopolar e...

Kadar besi (Fe) dan total suspensi solid (TSS) dalam air dapat diturunkan dengan menggunakan karbon aktif sebagai media adsorben juga nilai pH larutan dinetralkan. Karbon diperoleh dari arang, diantaranya adalah arang sekam padi kulit pisang kepok. Tujuan penelitian mengetahui bagaimana kualitas kapok variasi berat yang berbeda, pengaruh keefektivitasan kepok, penurunan kadar (Fe), TSS, penetra...

Garbage is the main problem causing environmental problems which are dominated by organic waste. Management of waste must be carried out extensively, one making eco-enzymes. This study aimed to determine production eco-enzymes from kitchen and characterization based on them. type research an experiment with a qualitative approach. The sample used mixture waste, namely include pH, COD, BOD, TSS,...

In this study, modelling of Konya wastewater treatment plant was studied by using artificial neural network with different architectures in Matlab software. All data were obtained from wastewater treatment plant of Konya during daily records over four month. Treatment efficiency of the plant was determined by taking into account of input values of pH, temperature, COD, TSS and BOD with output v...

the harvest date more influenced on postharvest quality during storage. in present study, fruits were harvested at four date base on total soluble solids content (5.5, 6.5, 7.5, and 8.5%) and then stored at 0.5 ºc and 80-90% rh, for 18 weeks. the samples were taken in 6th, 12th and 18th interval weeks and evaluated some parameters including weightless, losses, firmness, tss, ta, tss/ta, ascorbi...
