Hypochlorous Acid, Hypochlorite Ions or as dissolved elemental Chlorine. Free Available chlorine is 'free' in the sense that it has not reacted with anything and 'available' in the sense that it can and will react if needed.

Free Available Residual Chlorine (FRC) is Free Available Chlorine after treating the water with chlorine. That portion of the total available residual chlorine composed of Dissolved Chlorine gas cl2), Hypochlorous Acid (HOCl), and/or Hypochlorite Ion (OCl-) remaining in water after chlorination. This does not include chlorine that has combined with ammonia, nitrogen, or other compounds.

Chlorine total is the total amount added to the water for treatment. Chlorine free is the amount of chlorine available in the water for treatment. Chlorine total should always be equal to or greater than chlorine free.

Total chlorine is just as it sounds, the total amount of chlorine in the water. However when chlorine binds up with contaminants it forms a compound called "chloramines" that are no longer effective sanitizers and need to be removed through shocking. The chlorine that is still "good" to keep working is the free chlorine. If directions call for maintaining a 1ppm chlorine level, always make sure that matches your free chlorine reading.

YES. The Sigma III is designed to prevent algae and bacteria from growing in your pool water. Occasionally your pool may be filled with an overload of bacteria in a short period of time ( a storm or a pool party, for example). In such instances you will need to oxidize your pool in order to take care of the extreme levels of bacteria quickly. In this situation we recommend using a non-chlorine oxidizer, like potassium monopersulfate.

Developed by OLIN in 1928, this manufacturing process has provided for producing concentrated chlorine. This process was called “High Test Hypochlorite.” Nowadays, it is better known as its abbreviation, HTH. Calcium hypochlorite is often called “granular chlorine”. It is the form of chlorine most used by pool owners. First produced in 1785 by hypochlorite was produced in a chemical plant in Javel, France. Sodium hypochlorite is only stable as a solution.

Pool and spa water treatment with chlorine and other halogen disinfectants (bromine) require maintaining a residual concentration of at least 1 to 3 PPM (Part Per Million) in water. The effectiveness of the use of these chemicals is controlled by many variables: pH, dissolved solids, temperature and halogen concentrations. Under EPA urging, most municipalities now restrict the from dispensing and storage of chlorine.

In residential pools, there is no legal requirement to use chlorine at all. In fact, many ion users don't. They use a non chlorine shock or ozone and are very happy. However, we are not suggesting or recommending the ion system is an alternative to chlorine alone. There are reports that show that a low level of chlorine and the use of an ion system is a much better way to sanitize than either method alone.

Chlorine changes the tastes and odor of water. Chlorination can also produce harmful by-products called Trihalomethanes (THMs) which are linked to incidence of cancer. No, the UV unit will use about the same amount of energy as a 60 watt light bulb. It is a cost effective, natural way to increase water quality where microbiological contamination is present and to provide peace of mind where microbiological contamination is a greater risk.

Chlorine is an extremely reactive chemical. Right after the sodium hypochlorite is added to the water, chlorine levels decline because the chlorine is reacting with organic matter and microbes. After those reactions are complete, chlorine in water will slowly escape into the air as a gas.

No, there is no chlorine in chlorine dioxide. Although chlorine dioxide has the word chlorine in its name, the two chemicals have completely different chemical structures. The additional oxygen atom radically changes the molecule and creates completely different chemical behaviors and by-products. Their differences are as profound as those between hydrogen, the explosive gas, and hydrogen combined with oxygen, which creates dihydrogen oxide-commonly called water.

Due to technology limitations, some package types are not currently qualified as lead-free. Examples: Ball Grid Array (BGAs) and Flip Chips. Maxim Integrated Products BGAs are eutectic and the majority of Maxim Integrated Products BGA packages are 63%Sn / 37%Pb. However, we do have some volume of 10mm Chip Scale Ball Grid Array (CSBGA) packages which are Sn/Ag/Cu and contain no lead.
