Wastewater Treatment Plants Automation Master Plan
Introduction:
The City of Winnipeg has initiated a program to perform upgrades to the wastewater treatment systems at the NEWPCC, SEWPCC, and WEWPCC facilities. As part of these upgrades, automation systems are required for process control and monitoring. These automation systems must be installed to provide effective monitoring and control of the wastewater treatment processes. There are many methods of implementing an automation system, and the purpose of this document is to provide an overall strategy for automation installations that are consistent with the City’s needs. It is expected that this document will form the basis for future design work.

Installation of Optical Fibre Cables Inside Sewer Ducts
Summary
ITU-T Recommendation L.77 describes methods to install optical cables inside sewer ducts, which applies to both the cable installation and the pre-installation of an infrastructure, if requested. This Recommendation covers both man- and non-man-accessible sewer ducts. This Recommendation is not intended to address all of the safety concerns, if any, associated with its use. Therefore, it shall be the responsibility of the user of this Recommendation to establish appropriate health and safety practices and determine the applicability of regulatory limitations, if any, prior to its use.

Electrical Advanced-Level Training
Introduction:
This training is recommended for inspectors performing component design bases inspections (CDBIs) or other detailed inspections of electrical systems. Inspectors with demonstrated experience may be grandfathered in the completion of this training, if approved by the division director.
Completion of technical proficiency-level training (Appendix C in IMC 1245) is strongly recommended before beginning this training. You may complete the requirements in this training standard along with the general proficiency requirements contained in Appendix B and
the technical proficiency requirements in Appendix C.
Objectives of Advanced-Level Training This training focuses on the activities necessary to fully develop individuals as lead or “experts” in the electrical inspection area. It is not the intent that all certified inspectors will complete all of the ISAs in this advanced appendix. In addition, this appendix should also be viewed as an inspector’s aid and could be used during an inspection to assist in inspecting a particular area.

Electrodeionization versus Electrodialysis: A Clean- Up of Produced Water in Hydraulic Fracturing
Abstract:
Electrodeionization (EDI) is a widely studied process ranging from applications in wastewater clean-up in the food and beverage industry to purifying organic compounds. To date, there are no apparent studies on applying this technology to produced wastewater recovered from hydraulic fracking sites. Water consumption within hydraulic fracturing sites can reach in the upwards of millions of gallons per site, so a need for a water recycling process becomes necessary within areas where water requirements are scarce. Implementation of an EDI module that is capable of handling high salt solutions from produced wastewater in subsequent fracturing practices will decrease overall water demands, making this an environmentally sustainable process as well. This study will focus on the selective removal of high concentrations of ions using ion-selective membranes and ion exchange wafers in Wafer-Enhanced Electrodeionization (WE-EDI) of hydraulic fracturing solutions for improved water recovery and reuse within industrial applications. Experiments were performed using a WE-EDI setup with varied wafer composition and thickness in comparison with electrodialysis for selective removal of divalent ions (Ca2+) over monovalent ions (Na+ ) from simulated and fracking solutions. Research sought to show that when increasing the wafer thickness and changing the composition (weak acid compared to strong acid resins) there would be a greater overall current efficiency observed and subsequently lower power consumption. This research concluded that there is some degree of enhanced selectivity with increased wafer size, as well as varied composition compared to a traditional ED system. Continued research is recommended to conclude uncertainties, eliminate areas of system performance error and to further solidify all hypothesizes within this research.

Electrical Temperature Measurement
Electrical temperature measurement
The measurement of temperature is of special importance in numerous processes, with around 45% of all required measurement points associated with temperature. Applications include smelting, chemical reactions, food processing, energy measurement, and air conditioning. The applications mentioned are so very different, as are the service requirements imposed on the temperature sensors, their principle of operation, and their technical construction. In industrial processes, the measurement point is often a long way from the indication point; this may be demanded by the process conditions, with smelting and annealing furnaces, for example, or because central data acquisition is required. Often there is a requirement for further processing of the measurements in controllers or recorders.
The direct-reading thermometers familiar to us all in our everyday life are unsuitable for these applications; devices are needed that convert temperature into another form, an electrical signal. Incidentally, these electrical transducers are still referred to as thermometers, although, strictly speaking, what is meant is the transducer, comprising the sensor element and its surrounding protection fitting. In industrial electrical temperature measurement, pyrometers, resistance thermometers, and thermocouples are in common use. There are other measurement systems, such as oscillating quartz sensors and fiber-optic systems that have not yet found a wide application in the industry
