A new system for the delivery and application of brominated, chlorinated hydantoin
- Nalco Chemical Co., Naperville, IL (United States)
The use of brominated, chlorinated hydantoin (BCH) as a replacement for gaseous chlorine in cooling systems has increased rapidly over the last several years. A major reason behind the widespread use of the product is that it is relatively safe to use compared to gaseous chlorine and liquid sodium hypochlorite. Traditionally, the method used to apply BCH has been to unload the product from pails or super bags into by-pass feeders. Water is directed through the feeder to dissolve the product, and the dissolved BCH is then delivered to the target cooling system. The unloading of the BCH into a feeder can be dusty and burdensome for workers. In addition to the safety concerns associated with this operation, the empty pails and super bags must be disposed. A new system has been developed which eliminates the need to unload pail and super bags as well as the concerns associated with disposing of empty biocide containers. This paper discusses the design and operation of this new system as well as the benefits it provides.
