The concentration of residual chlorine present as dissolved gas, hypochlorous acid or hypochlorite, not combined with ammonia or in other less readily available form.
That portion of the total chlorine remaining in chlorinated water that is not combined with ammonia or nitrogen and will react chemically with undesirable or pathogenic organisms.
that portion of the total chlorine that is not combined chlorine and is available as a sanitizer. (N)
The chlorine which has not combined with other things in the water like algae or bacteria. This chlorine is what is still available for sanitizing and can also be considered the chlorine residual.
The amount of chlorine remaining after the chlorine demand has been satisfied. This is the most active form of chlorine that is free to kill bacteria and algae.
The amount of active chlorine remaining in water. Because it is not combined with anything it is ready to kill organic material.
Hypochlorous acid and hypochlorite available for disinfection
The chlorine that remains active after bacteria, algae and contaminants in the pool are destroyed, and the water is sanitary. The leftover chlorine is ready to fight off new contaminants.
(FAC) - (hypochlorous acid) the chlorine residual in pool water that is NOT combined & therefore able to kill bacteria and control algae entering the water.
The amount of free chlorine in the pool or spa water that is available to sanitize or disinfect the water. Sometimes called residual or available chlorine.
The killing, active form of chlorine.
The amount of chlorine able to sanitize water that is not tied up in chloramines. Haze: â€œCloudinessâ€ in water caused primarily by low sanitizer content, by very small floating particles and/or high pH.
The amount of free chlorine in the pool water that is available to oxidise, sanitise or disinfect the water. The level can be measured using a DPD1 test kit. It is also called residual chlorine or available chlorine.
Hypochlorous acid, the chlorine in swimming pool water that is not combined with ammonia or nitrogenous compounds, and therefore is available to kill bacteria entering the water. Se also available chlorine.
The amount of chlorine available in the water to kill bacteria or algae. This is sometimes referred to as Free Chlorine or Available Chlorine.
(Also called “chlorine residual” or “available chlorine.”) The amount of active chlorine remaining in the water after the chlorine demand to destroy algae, bacteria, or other contaminants has been satisfied. Recommended level of free chlorine is 1.0 - 4.0 ppm This provides protection against additional contaminants as they may be introduced into the pool.
