Dechlorination tablets for swimming pool waste water.
Why Dechlorinate Water
The toxicity of chlorine is not always understood since it is consumed by the average household everyday, and some of us swim in it at relatively high concentrations. However, the lethal concentration of sodium hypochlorite (chlorine) to rainbow trout is approximately 0.2 mg/L and for the Daphnia Pulex the lethal dose is approximately 0.03 mg/L (Source: US Environmental Protection Agency). What does this mean? It means that a pool that has 2 ppm (mg/L) of chlorine could pollute a body of water 10-100 times its size if sent to the storm drain. Similarly, hydrant flushing dechlorination programs could send 10,000 gallons or more at 0.2 ppm, per hydrant, to the environment. When sending these volumes of water to the storm drain, it is a very important matter that the chlorine be removed, and it's a simple procedure to use chlorine removal tablets as a means of removing that chlorine via tablet feeders or mats.
