The Tri-Max tablet feeder is the preferred system for your water main dechlorination flushing applications. One of the purposes of this system is for using high strength dechlorination tablets, such as Bio-Max tablets, to neutralize high levels of chlorine to make the water environmentally safe to discharge.
The purpose for the dechlorination process is to remove all excess chlorine from the flow before it is discharged. Large amounts of chlorine left in the water can be toxic to fish and other aquatic life, caution should be practiced when flushing any highly chlorinated water. We recommend checking with your local Health Department, as procedures vary from county to county.
