When it comes to designing, maintaining, and troubleshooting gas chlorination systems at some of the world’s largest water and wastewater treatment facilities, operators look to Bill Stimeling, De Nora’s Product Technology Manager for Chlorination and Chlorine Dioxide products. Having started his career as a wastewater treatment plant operator in a small town, he joined Capital Controls Company in 1978 as a field service engineer. He advanced through a variety of positions from project management, Int’l Sales Director, APAC Sales Director and into Product Management. You could say that Bill has ‘seen it all and done it all’ having worked with consultants, contractors, plant operators, utilities, and municipalities at some of the largest and complex facilities in the U.S., Asia, Latin America and the Middle East. However, there’s more to our expert than meets the eye. Those who know Bill say he has a knack for walking into any facility and immediately sensing what’s wrong and how to rectify the situation—down to the part number.

Not only is Bill a huge supporter of gas chlorination, he’s an adamant proponent of the importance of preventative maintenance and keeping to a strict schedule of rebuilding, repairs, and replacements. “Gas chlorination is king. Most of the biggest facilities in the world use it and there are good reasons why. It’s still the most economical and reliable way to disinfect water.”

Utility operators’ biggest concerns are, and should be, safety and performance—in that order. We’ve all read news stories about what can happen when something goes wrong and think, “that disaster could have been avoided.” Many times, the cause is related to a lapse in maintenance.

The disinfection system is a relatively small part of an entire treatment facility, but the most important in terms of reliability. If disinfection isn’t working, the plant shuts down—or worse. Taking care of your plant is job one and that means having a reliable source for service whether that be through your distributor or De Nora. We can provide contract and demand service, training, parts, and the assurance that your gas feeders are working properly. Our professionally trained engineers and technicians can perform an assessment, help develop a maintenance schedule or, alternatively, do the maintenance work ourselves.

Furthermore, because regulations are a driver in our business, disinfection is a changing landscape that needs careful monitoring and quick action. For instance, the potential for EPA future limits on Chlorate, already recommended by the World Health Organization, will affect the entire industry. We are the experts and can offer all of the disinfection technologies and application know-how to help you achieve the safety and performance to support your treatment goals.

Aftersales service and support are among the many reasons that customers choose De Nora. We understand that your equipment has varying service needs depending on age, maintenance, application, and duty cycle. Please review our recommended safety schedule to better plan regular and ongoing maintenance or contact your De Nora specialist at support.dnwt@denora.com
