The Wonderful World of Reverse Osmosis – 2021
Jane Kucera, Nalco Water, an Ecolab Company, Plainfield, IL – (repeat from Sunday)
Reverse osmosis (RO) has become a very popular and useful water demineralization tool, for both waterand 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. Hence, 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, pretreatment (including membrane filtration), 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.
Industrial Water Reuse – New Technologies and Lessons Learned
Ed Greenwood, Wood Environment & Infrastructure, Cambridge, Ontario, Canada
The primary objective of this workshop is knowledge transfer. It is aimed at those vested in developing the next generation industrial water reuse plant. Several workshop facilitators will objectively compare competing strategies to treat and recover wastewater for reuse. With many plants approaching 10 or 15 years of operation, the field of Industrial Water Reuse is maturing. Some reuse strategies have proven to be reliable and cost-effective but some have not. This workshop will explore the reasons why and address the common issues facing water reuse. Topics will include:
– Navigating the challenging and changing water treatment technology landscape – an unbiased comparison of popular treatment technologies (i.e. Clarifiers, MMF, MF, UF, GAC, IX, RO, ED, Chlorine, Ozone, AOP, UV)
– Common problems (design issues and performance issues)
– Emerging technologies and opportunities
– Optimizing cost and reliability
– Case Studies (success stories and cautionary tales)
Facilitators will encourage interactive discussion on case studies to unravel lessons learned. Participants will leave the workshop with a broad understanding of the water reuse landscape and how they might apply some of the more popular reuse strategies to develop the next generation water reuse plant.
Boiler Water Treatment for Industrial Plants
James Robinson, SUEZ Water Technology & Solutions, Horsham, PA
Participants will learn:
- How deaerators work and common errors that cause boiler feedline corrosion problems.
- Causes of downtime corrosion and steps to control it.
- The causes of flow accelerated corrosion and its control.
- The causes and control of boiler deposits and corrosion.
- The problems caused by steam contamination and steps to avoid these problems.
- The causes of condensate system corrosion and treatment technologies to control corrosion.
PFAS Treatment – Analysis, Design, Treatment and Destruction
John Peichel, SUEZ Water Technologies & Solutions, Minnetonka, MN
The objective is to educate attendees on the technical aspects of PFAS water, wastewater and groundwater contamination treatment including the challenges of water sampling, lab analysis, technology selection, lab and/or pilot testing, treatment system operation and final disposal/destruction of captured PFAS. The chemistry of PFAS is complicated due to the number of chemistry forms (4,000 + and counting) and in each case the optimum technology selection is based on the PFAS to be removed, interference of co-contaminants and the strategy for ultimate disposal and/or destruction of the PFCs.
This workshop is designed to educate attendees on the specific criteria to be considered for technology selection, optimization and effective operation. Practical consideration will be given to the applications development and common constraints often encountered in the initial sampling and water analyses. Technical details such as PFAS molecular weight will serve as method to prioritize technologies for potential cost effective treatment. This level of detail will be critical to the evaluation of activated carbon, ion exchange and reverse osmosis membranes used individually or in some combination.
