W01A: Water Treatment 101 (repeats from Sunday)
This workshop is a great introductory course covering the basic concepts of water treatment for industry. It will address unit operations (clarification, filtration, lime/soda ash softening, iron and manganese removal, membrane filters, and roughing demineralizers) used in water preparation for industry with emphasis on power, chemical industry, and refineries. It was include treatment of makeup water for cooling water systems as well as boiler water makeup. Wastewater generated by these unit operations and their treatment and disposal will be discussed. Basic water chemistry requirements for low, medium, and high pressure boilers will be considered with chemical conditioning as required.

W03A: The Wonderful World of Reverse Osmosis (repeats from Sunday)
Reverse osmosis (RO) has become a very popular and useful water treatment tool, for both water and wastewater applications. Understanding the fundamentals of RO, particularly as applications become more challenging in the environment of reduce, reuse, and recycle, is critical to optimal operations. However, during the growth or RO applications, some of the basics have been lost in shuffle. And, many times professionals and operators familiar with other demineralization technologies are now faced with operating RO systems with little or no training. This Workshop covers the basics and best practices of RO technology, from sound design to proper operating techniques. Fouling and concentration polarization, data collection and normalization, cleaning and storage are just some of the topics included in this Workshop. This Workshop is intended for all who need to understand the essentials of RO to help obtain optimal performance of this technology.

W04A: Wet FGD Chemistry and Operational Impacts on Wastewater Quality Discharge (repeats from Sunday)
This workshop will provide an overview of wet FGD chemistry and operating factors that will affect the wastewater quality. The various subsystems of the wet FGD system will be discussed including reagent handling, reagent preparation, absorber internals, recycle slurry, slurry spray headers, mist eliminators, primary dewatering, secondary dewatering, and wastewater treatment. The workshop will discuss the operational chemistry involved in removal of SO2 from the flue gas and highlight how operating parameters like pH, conductivity, ORP, and other issues affect the overall process. The workshop will also address how operation of the wet FGD system can affect the quality of the wastewater being discharged.

W05: Trouble shooting an Ion Exchange Mixed Bed Unit
In the water treatment plant the Ion exchange mixed units can be your best friend or worst enemy. Mixed bed can provide very high quality water, for days, weeks or even months without regeneration, this means less hand on by operations. Compared to normal demin trains that could regenerate up to twice/day, operators do not retain the day to day routine of regenerating a mixed bed which can lead to being unfamiliar with how to trouble shoot problem. When a mixed bed unit does not work properly – it could take months or even years to get it back into proper operation. This workshop will cover problems with improper backwashing or air mixing, mechanical failure inside the vessels and changes in feed water quality. In will also cover resin parameters, choosing the best resins for the application, the importance of chemical dosages, and what to look for in the resin reports. This workshop will include some of the author’s +40 years of experience with trouble shooting and repairing various mixed bed system in North America.

W06: Industrial Boiler Water Treatment
This workshop is intended for those interested in industrial steam systems operating at pressures up to 1800 psig. While some basic theory is covered, the main focus of the course is to provide practical information that can be used to avoid common system problems. The course covers deaerators, boilers, steam turbines and condensate systems from both mechanical operation and chemical treatment aspects. The causes of deposition and corrosion as well as water quality and monitoring guidelines and chemical treatment options are discussed in an informal atmosphere.

W07: Cooling Tower Water Systems 101 – How to Develop a Cooling Water Treatment Program and how to Determine if your Program is the most Cost Effective
This workshop discusses the problems commonly found in Cooling Tower Water systems and the various water treatments that can be used to control or prevent those problems. Specific water treatment chemicals are discussed and their advantages and disadvantages are presented. These specific chemicals are for corrosion, scale, fouling, and microbiological control. They are identified generically and include the most recent developments. The preparation of the complete water treatment program is provided in easy to apply steps. This workshop is excellent for operators, utility mangers, and water treatment suppliers both new on the job and great as a refresher for others. Bring your cooling tower water treatment program information.

W08: Wastewater Treatment 101
In this workshop, wastewater treatment process fundamentals will be discussed for in depth understanding of how the operating & processing units work in aerobic environment to treat the waste streams from refineries and chemical plants. Object of this course is to acquire basics of how to design, an open art robust wastewater system to produce acceptable quality effluent to be discharged into an approved estuary and or in pant make up water resource for cooling tower or steam generation. Instructions will include wastewater streams inventory and selective segregation to optimize pre-treatment processing units, such as, API, CPI, DAF, and IGF units. Conventional Activated Sludge bio reactors, secondary clarifiers, controlled returned activated sludge (RAS) and controlled waste activated sludge (WAS) and sludge dewatering etc. will be discussed. Design example of a typical refinery wastewater plant and video tutorials will be used to enhance understanding wastewater treatment process.
Approximate Subject matter outline:
- Identification of typical refinery wastewater streams
- Selective segregation & pretreatment of wastewater streams
- Microbiology and identification of Microbes for optimum design
- Primary, Secondary & Tertiary Operating units
- Solids production and Disposal management
- Tutorial videos on selected topics
- Typical refinery wastewater design example
