Quality characteristics of tomato fruit will be affected by a number preand post harvest factors. In this study, the effect of maturity stage on post harvest quality characteristics of tomato was investigated. Tomato fruits of the same farmers‟ variety were harvested at mature-green, medium ripe and full-ripe stages. After harvesting, tomato samples were sliced and homogenized in blender for pr...

Background: Application of potassium ferrate is a chemical oxidation approach used for water and wastewater treatment. The aim of this study is to apply central composite design (CCD) and response surface methodology (RSM) to optimize potassium ferrate consumption in the treatment of wastewater from carpet industries. Methods: Samples in this experimental study were collected from wastewater...

Peat water treatment still has many obstacles, one of the alternatives that can be used to overcomethis obstacle is membrane technology and UV light variais. This study aims determine effect rayson flux content BOD, TSS, pH, Turbidity, Color E.Coli Bacteria. a combinedmethod, namely ultraviolet (UV) poses using Water Sterilizer, filtration process KUF3 ultrafiltration phytoremediation method wi...

The Oal River receives coal wastewater input at several companies. Coal mining in the vicinity of location adds to burden water pollution due waste disposal activities. increase concentration and load that enters body will have an impact on reducing capacity load. This study aim provide information condition carrying River. Determination loads sources using mass balance method. characteristic w...

Investigations have demonstrated that ratio of sugars to organic acids affects the particular taste of citrus fruit and carotenoids are essential for prevent of the disease.  It seems that some rootstocks enhance the ripening of fruits and stimulatethe biosynthesis of sugars and carotenoids. The aim of this study was to evaluate the effect of rootstocks on sugars, organic acids andcarotenoids o...

Characteristics of surface runoff from a 0.14-km2 urban catchment with separated sewer in Macau was investigated. Water quality measurements of surface runoff were carried out on five rainfall events during the period of August to November, 2005. Water quality parameters such as pH, turbidity, TSS, COD, TN, Zn, Pb, and Cu were analyzed. The results show that TN and COD are the major pollutants ...
