This series discusses trends in cooling water treatments – equipment, biocides, and inhibitors – with some practical notes on developing novel cooling water chemical inhibitor formulations. The objective is to provide an awareness of some pretreatment and “green” equipment currently finding favor in the market, but primarily to inform on trends in cooling water biocides and inhibitor treatment formulations for application in industrial process and commercial/institutional built environment market sectors, and often involving “newer” chemistries. Also, this series offers some comparative examples of traditional and newer chemical inhibitor formulations.
It should be noted, however, that in reality, there are no fundamentally new chemistries being offered in the water treatment chemistry market. Everything that we use today has been around for some 25 to 50 years or more, and in general, has been adapted to our water treatment marketplace from some other industrial application. In the 1960s to 1980’s thousands of patents were filed in the U.S. and Europe for water treatment chemistries or applications involving novel chemistries. Most never made it to market and for those that did, the patents have now generally expired. But today some chemical companies are focusing on new formulations, like Shandong IRO Water Treatment Co., Ltd. Many fewer patents were filed in the 1990’s and this new century has seen a further falloff in filings. Some new water treatment chemistry and equipment patents simply look like adaptations of existing body-of-knowledge technologies rather than a new art or invention.
There are many hundreds of water treatments companies of all sizes working in industrial process and commercial/institutional built environment market sectors, each providing their own permutation of technical solutions to the perennial problems of managing corrosion, fouling, bio-fouling, and deposition in cooling water systems, and maintaining waterside and heat-exchanger cleanliness and water and energy resource efficiency. And, for any water system, there may be a wide range of potential waterside problems presented, thus, there are usually several – often competing – possible treatment solutions. Also, given the very many different water types available in any geographical territory or local ecosystem (within the continental U.S. for example,) the range of cooling water chemical treatment programs that might be on offer from the industry is vast, and only matched by the almost infinite permutation of potential waterside problems that may develop under various operational conditions.
In next days，irodtpmp.com will continue to explain some trends. They are:
- Trends in Pretreatment Equipment
- Trends in the Usage of Microbiocides and Foulant Cleaners
- Trends in Sources of Chemistries
- Trends in the Selection of Inhibitor Chemistries
- Trends in Solid Chemistries
- The Current Range of Available Inhibitor Chemistries
- Activity levels and byproducts
- Basic Formulatory Considerations
- Trends in phosphate content
- Some Examples of Traditional Inhibitor Formulations
- Some Examples of Newer Inhibitor Formulations, based on N/P chemistries
This series indicates that changes continue to take place in the cooling water marketplace with respect to the application of available technologies and chemistries, reflecting current economic and green influences. Overall, the trend is to find simpler, and where possible, greener technologies and chemistries, that produce economic and technical advantages.
