Common Halogen Disinfectants ... It is used in a variety of industrial and consumer appliions. ... Bromine is an alternative to chlorine for water disinfection.

These two are chlorine and bromine. Each provides a specific benefit to the overall safety and functionality of electronics but pose a threat to the continuity of life for humans and nature. Functionality of Chlorine. The element chlorine is used in a wide array of products.
The rate for the reactions of chlorine and bromine with phenolic compounds is pHdependent due to the differences in reactivity of the hypohalous acid and the hypohalite anion and the higher reactivity of the phenolate compared to the phenol (Rebenne et al., 1996, Gallard and von Gunten, 2002, Deborde and von Gunten, 2008, Heeb et al., 2014).
Stabilized chlorine products sanitize your pool water and kill bacteria. Stabilized chlorine products are protected from sunlight degradation and are an ideal for keeping your pool clear and clean. They are available in a variety of forms: 3" chlorinating tablets, 1" chlorinating tablets, chlorinating sticks, and chlorinating concentrate.
Spa Sanitizer – Bromine or Chlorine; Spa pH increaser and decreaser; Spa Alkalinity and Calcium Increaser; Spa Shock – Chlorine or MPS; As a minimum, you'll need most of these spa chemicals. You may use primarily pH down and not so much pH up, probably adjusting 23x per month.
Essentially, the pool will be creating its own chlorine or bromine. The water that is found in the salt water spa is nothing like the water in the ocean. To begin with, the salt concentrations in oceans can fall between ten thousand to upwards of thirty five thousand parts per million.

The HaloSense range is suitable for total or free residual chlorine monitoring or control appliions in potable water, seawater, process water, swimming pool water, waste water, food washing, paper and ...
Suitable for gas chlorine, liquid chlorine, bromine, and a variety of feed devices. System 3i is designed for use on recirculated appliions such as pools, spas, and fountains. The Strantrol System 3i controller utilizes High Resolution Redox ® (HRR) technology to directly measure the rate of oxidation in pool water regardless of the pH, temperature .
