REACTIVE EXTRUSION OF PET TEXTILE TRIM WITH PET BEVERAGE CONTAINERS WITH VARIOUS AD

The objective of our project is to design a method to reuse PET trim waste back into useable product for Hematite Manufacturing. This will be done by increasing the intrinsic viscosity of PET nonwoven textile trim waste. The options used to achieve this will consist of either the addition of recycled PET beverage containers into the PET trim waste or the addition of chemical additives through reactive extrusion. Upon successful extrusion of the PET, the products will be put through a melt flow index and ultimate tensile strength test to ensure all desired mechanical properties are achieved.

6T PAPER MACHINE EFFLUENT TREATMENT

This project in collaboration with Irving Tissue Toronto involves designing a wastewater treatment unit to assist the paper mill with their effluent high TSS content. The paper mill discharges high volumes of effluent containing large amounts of solids including Total Suspended Solids and the organic oil to the City for treatment. As a result of extensive testing and investigations, a Dissolved-Air-Flotation unit was selected as the ideal treatment unit to reduce the TSS content where the solids are collected as sludge and treated wastewater released to the City.

COUPLED CAUSTIC AND CHLORATE PROCESS

The two largest chemicals reagents used by a kraft pulping process are sodium hydroxide and sodium chlorate. Due to rising supplier costs, many pulp mills have expressed interest in producing these two chemicals on site to reduce production costs.  Our process uses an electrolytic membrane cell that produces these two chemicals at a significantly reduced energy cost compared to current methods. This is achieved by synthesizing both chemicals with a single cell and state of the art oxygen depolarized cathode (ODC) technology.

AUTOMATED HEAT BALANCE PROGRAM FOR CANDU REACTOR

The primary heat transport system of the CANDU reactor at Bruce Power is adjusted by a heat balance conducted twice a day. The automated heat balance (HB) program can increase the net output of the reactor by reducing the difference between true reactor thermal power (RTP) and calculated RTP, remove process inefficiencies, and eliminate human performance error. The HB program incorporates pre-filtering methodology to identify the status of the reactor and determines if it is operating at steady state.
