Concerned About Future Bromate, Chlorate, and Perchlorate EPA Regulations? Feeling the Pressure to Reduce Operating Expenses? Take A Look at a New ClorTec Retrofit Program from De Nora. by Dave McWalters
It’s clear that water and wastewater companies want disinfection and oxidation equipment that’s robust, serviceable, able to get up and running quickly, and provides access to knowledgeable technicians in a timely manner. Over the years, De Nora has provided all of that—and the peace of mind that comes from a track record of product reliability and excellent service. We continue to provide a variety of services to our hypochlorite generators with quality, capable technicians. What we didn’t have until recently; however, was an upgrade program to retrofit our older equipment with newer technology. The EPA’s recommended bromate, chlorate, and perchlorate limits, while not a regulation currently, coupled with increasing operating expenses driven by the high cost of salt, have caused many of us in the industry to wake up and take a programmatic look at addressing this burgeoning need. That’s why we created a new retrofit program to upgrade De Nora systems. This program called ClorTec Gen III is specifically designed for those systems that handle volumes of 450lbs/day or more and are over five years old, basically a generation prior to the most current technology.

Consider our ClorTec Gen III program to see how it may apply to your facility. As with any service program, our technicians will first conduct an on-site survey to understand the condition, age, capacity, and any issues with your current equipment. Then we’ll recommend one of several upgrade kits to make your system compliant with the current Gen III technology. Our scope of work may include some combination of the following equipment: Gen III Hypo Generator Rack (with or without cells), replacement of acrylic cells with PVC/FRP cells, upgrading or replacing your control panel, replacing the rectifier (whether air or oil coiled), and/or adding a water chiller. In addition to a complete 20-point system service check, we will include a warranty (standard or extended) and a maintenance agreement to keep your new system up and running reliably.

Your ‘new’ ClorTec Sodium Hypochlorite Generator will provide a number of important benefits. Safety: with less than 1% chlorine concentration and the lowest disinfection by-product impact available today. Lower Operating Costs: with the most efficient OSHG available requiring the lowest amount of salt, as well as low maintenance and service costs. Reliability: with a simple system design, quality parts, and long electrolyzer life. Green Footprint: with the lowest carbon footprint impact and no plastic packaging of chemicals. All of this is backed by De Nora, a leader in OSHG with over 6000 installations, cutting-edge innovation and research, and worldwide R&D and support.

As an example, one of our customers, the second largest provider of potable water in Cobb County Georgia, relies on two water treatment facilities to prepare water for wholesale distribution to 11 retail water suppliers, as well as industry and institutional customers. The historic use of chlorine gas became a potential concern not only in Georgia, but across the entire county. Their first installation of a ClorTec system, supplying 1500lbs/day of sodium hypochlorite, eliminated the need for bulk chemical storage and lowered its disinfection byproducts. Today, with three generators, two operating at a time, the latest high-efficiency Gen III upgrades are well received, providing 7-9 hour run times and excellent production of potable water for its satisfied customers. In addition, the new instrumentation panel with analog signals enables them to have greater flow control, better diagnostics, and peace of mind.

Get ahead of upcoming EPA regulations, lower your operating expenses, and benefit from the safety features available through De Nora. Contact xxx to get more information about the new Gen III retrofit/upgrade program or any of our service and support options for ClorTec customers.
