W09: Water Treatment 201
This course reviews the topics covered in Water Treatment 101 and build on those to provide design and technical details on designing water treatment systems using supplier’s equipment information. Unit processes covered in this course are pretreatment softening using lime and soda ash, sodium cycle ion‐exchange for softening, demineralization of pretreated raw water using cation/ anion/ mixed‐bed ion‐exchange systems, reverse osmosis, and EDI. Boiler water chemistry guidelines and chemicals feeds for boiler chemistry control for high pressure power plant boilers, combined cycle plants, and industrial boilers (up to 1500 psi) will be discussed. Advanced wastewater treatment concepts for power plants, industrial plants, and refineries will be included with recycle and reuse when feasible.

W10: Contaminants A to Z, Best Available Removal Technologies
A fast moving presentation on the more common contaminants found in water, their general behavior, how they get into water, and the best available technologies for their removal. Chapters include naturally occurring and man-made trace contaminants, radioactive contaminants, plating residuals, oxidation byproducts, organic contaminants, dissolved gasses, and a special bonus section about bulk ions. Approximately 100 of the more common contaminants found in water are covered, however due to time constraints, not every contaminant is covered orally. Students are encouraged to suggest the contaminants of greatest interest so they can be given extra attention.

W11: Electrodeionization (EDI)
Electrodeionization (EDI) is a hybrid of two well-known processes, ion-exchange deionization (IX) and electrodialysis (ED). It was developed to allow the production of deionized water without the use of the hazardous acid and caustic that is required to regenerate ion exchange resins. EDI is now over 30 years old and is used extensively in many industries, especially in the production of deionized water for pharmaceutical formulations, power generation and manufacture of microelectronics/semiconductor devices. It is usually employed as a polishing demineralization step with reverse osmosis (RO) upstream as the roughing demineralizer. This workshop will start by reviewing the principles of the EDI process, how it differs from IX, how EDI modules are constructed, and EDI feed water requirements. It will then focus on practical aspects of EDI system design, operation, maintenance and troubleshooting.This is an introductory course that requires no prior exposure to electrodeionization or electrodialysis. Some prior knowledge of basic water chemistry will be helpful.

W12: Evaporative Water Treatment Fundamentals for Steam Generating EOR Processes
Evaporative water treatment may seem complex at surface‐level, but once the underlying principles are understood, evaporation system design and operation become very straightforward. This course is designed to explore everything from evaporator design to its integration into various EOR processes: including steam-flood, SAGD and CSS. Students will come away from this course with a practical understanding of how evaporators work, why they work and how they are used in the oil & gas industry to solve real problems. Course matter will cover evaporative boiler feed water production (either OTSG’s or drum boilers) and brine discharge reduction strategies. A particular emphasis will be placed on produced water chemistry variation and design implications. Unit operations such as falling-film evaporation and crystallization will be covered in‐depth. Several real‐world case studies will be examined to reinforce theoretical principles and students will work through several design optimization problems.

W13: HRSG and High Pressure (>900 PSIG/60 BAR) Boiler Water Treatment and Operation
This workshop will cover the water quality required for high pressure (>900 psig/60 bar) steam boilers including the various treatments being used and new developments relative to protection from scale and corrosion. The course will also cover treatment issues related to pre‐boiler systems and the condensate systems and a discussion of controls and troubleshooting techniques. Operators, utility plant supervisors, managers, and engineers can all benefit greatly from the practical information provided in this course.

W14: Cooling Tower Water Systems – How to Successfully go From Fresh Makeup Water to Recycled Waters
This workshop will cover guidelines to be used in developing a cooling water treatment technology going from fresh to recycle waters as makeup. These guidelines will identify possible concerns and potential benefits with recycle water. A step by step approach is provided not only for existing cooling tower water systems but also new systems that can handle almost any recycled waters. A number of case histories are provided. Attendees are encouraged to bring not only any questions but also details on their cooling tower water systems and the recycle water quality being considered. A must workshop for operators, utility managers, and for water treatment suppliers.

W15: Arsenic and Selenium in Wastewater Treatment
Changes in regulations in the coal-fired power industry and existing standards in the mining industry are but two examples of increased regulatory focus on arsenic and selenium. These ions have not been the focus of emphasis for widespread industrial treatment in the past. Numerous new technologies have been promoted for use in the treatment of arsenic and selenium. However, it is difficult for the environmental personnel responsible for making intelligent decisions in this area to assess the real potential of treatment technologies to cost-effectively achieve the desired goals. This course will provide the background necessary for those concerned with arsenic, selenium or both to make sound decisions about the technical direction of treatment options.
