The color removal of three reactive dyes in an aquatic system without priortreatment was studied. Selected commercial dyes were treated with NaC102 andUV as oxidation agents. Effects of nature of oxidant, temperature, pH ofsolutions, concentration of C107—, contact time of C102— and UV irradiation wereinvestigated. Optimal C102— concentration for color removal in the absence of UVirradiation wa...

background; conventional chemical coagulation is considered as the old method to color and cod removal in textile effluent. electrocoagulation (ec) process is a robust method to achieve maximum removal. methods; this work was designed to compare the result of operational parameters including optimum ph and coagulant concentration for chemical coagulation with ferric chloride and alum. also, the...

The decorrelation stretch is a process that is used to enhance (stretch) the color differences found in a color image. The method used to do this includes the removal of the inter-channel correlation found in the input pixels; hence, the term "decorrelation stretch". The purpose of this document is to explain: 1) the conditions that normally appear in multispectral data that indicate that color...

In this study, the Fenton process was used to investigate the color removal efficiency of Acid Red 52 and Basic Red 18 dye solutions by direct chemical oxidation. Color and chemical oxygen demand (COD) was successfully removed more than 99% and up to 92% respectively. This article would provide an easy assessment of the viability of using Fenton reagent in acidic conditions, so it is a prom...

New methods and tools for 3D-modeling using range and intensity images Alejandro J. Troccoli Systems for the creation of photorealistic models using range scans and digital photographs are becoming increasingly popular in a wide range of fields, from reverse engineering to cultural heritage preservation. These systems typically employ a range finder to acquire the geometry information and a dig...

in this study, the ashes of poplar tree leaves are applied as an efficient, accessible and inexpensive biosorbent for the removal of heavy metals pb2+ and cu+2 in aqueous solutions. in the adsorption processes, the success of the ions removal highly depends on the level of several experimental factors such as ph, contact time, adsorbent dosage and temperature. therefore, a genuine statistical e...

the purpose of this study is to investigate the accuracy of predictions of aniline removal efficiency in a moving bed biofilm reactor (mbbr) by various methods, namely by rbf, anfis, and fuzzy regression analysis. the reactor was operated in an aerobic batch and was filled by light expanded clay aggregate (leca) as a carrier for the treatment of aniline synthetic wastewater. exploratory data an...

We study a linear fractional differential equation with a periodic boundary condition and give the explicit form of the solution and the corresponding Green’s function. Using some properties of the Green’s function we present some new comparison results.
