Our trusted liquid chlorinating compound has three primary uses:

  • Industrial and commercial water sanitization and purification

It's All in the Science

According to the American Chemistry Council (ACC), “Chlorine is produced from one of nature’s most plentiful and inexhaustible minerals—common salt, sodium chloride. Yes, the same white solid you sprinkle on your baked potato!”

“Chlorine chemistry plays a key role in protecting our drinking water and helping to keep swimming pools healthy. It safely eliminates bacteria, viruses and parasites from water and ensures lasting disinfection during the journey from the water treatment facility to the faucet.”

The Long Heritage of Liquid Sanitization

Sodium hypochlorite has a long and trusted history. Liquid chlorinating compounds have been used in municipal drinking water for the past century, and in swimming treatment for more than 50 years. This trusted water treatment technology is truly a part of the American story.

A Part of the American Story...

Even in the early part of the 20th Century, waterborne diseases such as typhoid and dysentery were common and accounted for fatalities even in the U.S. The introduction of chlorine in drinking water marked a major advancement in public heath and helped to eradicate everyday health ills and sanitize our nation’s tap water. It has enabled industries across vertical sectors to ensure that pathogens and bacteria remain out of essential water systems.

Similarly, sodium hypochlorite was introduced as the leading method of swimming pool and hot tub sanitization mid-century and has been the de facto gold standard method for keeping one of our favorite national pastimes safe. To this day, it plays a vital role in protecting one of leading forms of outdoor recreation in seasonally warm months healthy and enjoyable for millions of families across America.

HASA is proud to be a part of this heritage—helping to keep our water Safe, Clean, and Clear since 1964.
