Methods to treat kinetic data for the biodegradation of different plastic materials are comparatively discussed. Different samples commercial formulates were tested aerobic in compost, following standard ISO14855. Starting from raw data, conversion vs. time entries elaborated using relatively simple models, such as integrated equations zero, first and second order, through Wilkinson model, or a...

ginger waste material (gwm) has been utilized as adsorbent for removal of hazardouspatent blue vf (pbvf) dye from aqueous solution. batch adsorption experiments wereperformed as a function of ph, contact time, dye concentration, adsorbent dose and temperature.the optimum ph required for the maximum adsorption was found to be 2. the experimentalequilibrium adsorption data were tested using langm...

The effect of temperatures below 20 degrees C (20, 15 and 10 degrees C) on the anaerobic degradation pathway and kinetics of domestic wastewater fractionated at different sizes was studied in a fluidized-bed batch reactor. The overall degradation pathway was characterized by a soluble fraction degrading according to zero-order kinetics and a colloidal fraction (between 0.45 and 4.5 microm) that...

The color, texture and rancidity of dried fruit are critical parameters to control for consumer acceptance. goal this research was investigate the kinetics color parameter changes in terms crispness peroxide value (PV) coconut chips by using zero-, first- second-order kinetic reactions during storage at different temperatures, as well shelf life prediction accelerated method. outcomes demonstra...

A laboratory scale aerobic fixed film bioreactor packed with glass beads for biofilm growth was used to evaluate the removal efficiencies of COD and phenol for a carbohydrate—phenol mixture in wastewater. It was done by an indigenous mixed culture inoculums developed after collecting sludge from a return line of an activated sludge plant. The test result on continuous flow in the above biofilm ...
