Flow Reversal and Pressure pulsation: Innovative technique to enhance flux in Nanofiltration
Abstract: Reduction in Permeate flux with the period of time is the major drawback for the Pressure-driven membrane processes. Concentration polarization and membrane fouling are the two major limitations for the Pressure-driven membrane filtration processes. They lead to the severe flux decline and that need to be controlled for the better process efficiency. The resistance determination provides basis for selection of membrane and appropriate pressure –driven separation process. This paper outlines …

The theoretical study of behavior of the gas bubble, fixed on the surface of a solid material, under simultaneous changes of the surface tension on the border section of the phases of the fluid-gas and contact angle
Abstract: In the practice of ore and particular coal flotation, the injection of oils (nonpolar reagents) into the flotation pulp intensifies the process of the flotation, separation of the particles of different minerals, and contributes of extraction into the foam product considerably of the larger and heavier particles, no floating before. However, conducted studies to present time do not permit to explain significant strengthening of contact between the bubble and the …

Gluconic acid production from cane molasses using Aspergillus carneus
Abstract: Gluconic acid is a multifunctional organic acid, non-volatile, non-corrosive, non-toxic, readily biodegradable, with environmentally friendly properties. In this study, gluconic acid was produced from the treated molasses using Aspergillus carneus strain under the submerged fermentation. The parameters were studied using the four-factor, three-level Box-Behnken design using using Design Expert ® version 11. The acid produced was characterized using the Fourier transform infrared spectroscopy. The optimum values of the parameters were …

Sequestration of Cr(VI) by the Activated Carbon prepared from Coffee husk(CHAC)
Abstract: The potential of Coffee husks for the production of a low-cost activated carbon (CHAC) was investigated in this study. During the synthesis of the adsorbent, the concentration of the activating agent (H3PO4), impregnation ratio, carbonization temperature and holding time were optimized by Response Surface Method (RSM) using Box-Behnken design. Further, the application of coffee husk activated carbon for Cr (VI) adsorption from aqueous solution was investigated.
