Pure Water Applications Using Electrodeionzation
The use of Electrodeionzation (EDI) for water purification continues to grow.  Environment safety concerns and improvements to the technology have gained an increased acceptance for Industrial applications.  The session will review traditional mixed bed ion exchange challenged by EDI technology and power plant water purification.

Water Reuse
Reclaim water use in industry is critical in securing a viable environmental future. This Session includes industry champions who will use actual experiences and case studies in describing solutions to unforeseen challenges. They will be using actual data, water balance modeling and experiences to implement operational strategies when describing lessons learned.

Reclaim water from POTW’s along with other sources of water will be reviewed as alternate sources to fresh water in the Power generation industry. Reclaim use and its concentration in the plant also affects wastewater discharge from both a regulatory aspect and discharge location. Come and give us your hands-on experiences, in our discussion following each paper.

Produced Water Treatment
Every oil producing/Hydraulic fracturing for Oil & Gas production facility have an undesirable end product, called produced water. Depending upon the formation and production methods used to extract these products i.e., steam flooding or water flooding, we can expect produced water with different composition consisting of oil & grease, dissolved solids, heavy metals and silica. Depending upon the end use and other Regulatory mandated disposal requirements, produced water treatment can be a technical and capital intensive task. In this session, we have three excellent technical papers in which the authors will share their innovative technical skills and methodology on how best to treat and manage the produced water for optimum usage and disposal.

Design and Operation of Zero Liquid Discharge Systems (ZLD)
Zero Liquid Discharge (ZLD) represents the ultimate in water utilization effi ciency and responsiveness to environmental discharge concerns. In some confi gurations, this powerful technology is capable of recovering nearly every drop of water entering the site while freeing the owner from variable and increasingly stringent discharge requirements. ZLD selection and configuration depend on numerous factors including fuel source, water chemistry, climate, environmental requirements, CapEx, and OpEx. The papers in this session will help you navigate through the many ZLD strategies, select the most appropriate ZLD system for your site, and share valuable ZLD operating experience.

Updates and Innovation in Mine Water Treatment
Mine water treatment in the United States is driven by Federal and State water quality protection programs, requiring high efficiency removals of metals prior to discharge of water that has come into contact with ore and wastes or that has been dewatered from mineral-bearing zones in the mine workings.  Scientific investigations into the effects of metals on the aquatic environment continue to result in more stringent water quality standards.  The 2014 IWC mining session will explore the performance of two biological treatment technologies for selenium removal, including fluidized and packed bed treatment, in achieving low effluent concentrations.  Attendees will be able to compare and contrast the merits of each technology for future applications.  In addition, two innovations in metals treatment processes will be presented that hold promise as viable alternatives to standard lime treatment for heavy metals removal.  The innovations include utilization of chemical oxidation in a lime high-density sludge plant, and use of electrocoagulation to reduce chemical dosing requirements. Both innovations also reduce sludge production.  This session will provide food for thought when planning new mine water treatment plants or existing plant upgrades.

Advances in Ion Exchange Operations
Pure water is an essential part of nearly all industrial processes ranging from process steam production to nuclear power generation. The need for effective and efficient pure water production is often overlooked due to the immediate needs of just producing enough water to satisfy the daily demand. Water treatment technology that exists today provides the water treatment plant operators and management an opportunity to improve their efficiency and while not having to sacrifice efficacy.

Anticipating New Discharge Requirements for FGD-Equipped Power Plants
Power plants equipped with flue gas desulfurization (FGD) systems face challenging wastewater issues.  Most notably, the U.S. Environmental Protection Agency (EPA) has proposed new Effluent Limitation Guidelines (ELG) that aim to significantly tighten discharge limits on mercury, selenium, arsenic and nitrates across the U.S.  Other contaminants of increasing concern, such as boron, will also be subject to mitigation efforts.  Since FGD wastewaters involve complex chemistries, meeting more stringent discharge requirements is rarely simple, and usually requires exploring and advancing state-of-the-art approaches.  This session provides some recent learnings from real-world efforts to reduce wastewater discharges at FGD-equipped power plants.

Practical Application of Membrane Pretreatment and Technologies
This year’s IWC Membrane Session covers real-world application of the technology.  The papers in this session cover a full gamut of subjects ranging from pretreatment alternatives to chlorine for bio control to multi-membrane processes for zero liquid discharge (ZLD).  All are important topics as industry becomes more environmentally conscious either to be green or to follow governmental regulations.  One paper paper discusses in detail chlorine and alternatives to chlorine for membrane bio control to minimize formation of disinfectant byproducts.  Another paper discusses the replacement of an antiquated demineralizer system with a design, build, own, operate, and maintain system.  A third paper discusses a unique crystallization technique that lends itself to pretreatment prior to an ultrafiltration/nanofiltration/ reverse osmosis ZLD system.   And a fourth paper discusses a membrane–based system used for water recycle at a methanol production plant.

Cooling Water Treatment - Improving Monitoring, Performance and System Efficiencies
Corrosion, deposition and microbial growth are closely interrelated and must be properly controlled to maintain overall cooling water system efficiencies.  If any of these three aspects are left unchecked, the cooling water treatment program will suffer poor performance.  The four papers in this session cover different areas of a cooling water treatment program.  The first paper discusses corrosion monitoring under heat transfer conditions while the second paper targets cooling tower film fill fouling / monitoring.  The third paper outlines the impact and control for mussels discovered at Lead Mead.  The final paper completes the session with the treatment of high silica cooling water.

Power Generation Past and Present – Refining Pretreatment and Demineralization Design Technologies and Innovating with Renewables
Renewable technologies such as solar and geothermal may be adapted at power generation facilities to offset the auxiliary load of the plant or even replace traditional fossil generation.  These renewable technologies bring with them new water treatment challenges.  While these innovative renewable technologies are making their debut, refinements to existing core water treatment technologies that treat water for steam and cooling applications at power generation facilities, are ongoing.  These refinements in traditional technologies are essential to keep up with changing environmental wastewater discharge regulations, more stringent steam purity requirements, and reduce water usage. This session covers a broad range of water treatment applications in the power generation industry from renewables to raw water quality data collection and analysis, demineralization, and wastewater treatment.
