Factorial experiments were conducted to investigate the effect of chlorination filtrate recycle on toxicity and organically bound chlorine in the first two stages of softwood kraftpulp bleaching. The effects of the mode of chemical addition, the substitution of chlorine dioxide, and the kappa factor were also studied. A continuous laboratory-scale (6.0 o.d.g/min) chlorination apparatus was desi...

Process variation reduces a pipeline’s maximum attainable frequency by creating unbalance in the stage delays. As a result, the pipeline ends up cycling with a period close to that of the slowest pipeline stage. ReCycle was proposed in ISCA 2007 as a framework for comprehensively applying cycle time stealing to balance the stage delays under process variation, thereby allowing the pipeline to c...

The application of process control automation software for the recycle of peroxide bleaching rinse water to fabric scouring on a continuous preparation range is presented. Analytical data taken on wastewater samples document operating conditions of the preparation range and the quality of the recycle water. An economic analysis of the recycle process and the cost of range modifications to insta...

The Recycling rate among developing nation is very low and the number of waste is increasing every day. Although many steps have been taken such as through national campaign, yet the recycle rate remains unchanged especially in Malaysia. Thus, the smart recycle bin is proposed to give a reward to public user who thrown the recyclable waste into the innovated smart recycle bin by giving points (...

This paper presents the retrofit of five conventional distillation trains for the separation of quaternary mixtures of hydrocarbons for feed compositions with high or low content of intermediate components. The retrofit implies the incorporation of liquid or vapour recycle streams among the conventional distillation columns. Each recycle stream removes one condenser or one reboiler. The introdu...

Municipal wastewater treatment plants (WWTPs) could become valuable contributors to a circular economy by implementing the 3R principles (reduce, reuse, and recycle). While reducing pollution load of sewage is primary objective WWTP, this process generates several potentially byproducts including treated effluent, biogas, sludge. The effluent can be reused in various end use applications biogas...

Analysis of deleted files often provides useful information for the forensic computer examiner. Knowing where to find the deleted files, and how to interpret the metadata associated with the file’s deletion, make up the cornerstone of a successful forensic computer examination. Much like an office trash-can, the Microsoft Windows Recycle Bin is a temporary holding container for files that have ...

Synthetic juice clarification was done through spiral wound ultrafiltration (UF) membrane module. Synthetic juice was clarified at two different operating conditions, such as, with and without permeates recycle at turbulent flow regime. The performance of spiral wound ultrafiltration membrane was analyzed during clarification of synthetic juice. Synthetic juice was the mixture of deionized wate...

Aquatic macrophytes have been widely studied because of their capability of absorbing contaminants from water and their subsequent use in biomonitoring. This study presents a comparison of Cr accumulating potential of submerged aquatic plants viz Vallisneria spiralis and Hydrilla verticillata. These plants were treated with various concentrations of treated tannery effluent collected from UASB,...
