What Is Free Chlorine Ppm. Free chlorine is the conventional chlorine that you add to your pool. The initial point where free ‘available’ chlorine residual is present / detected breakpoint residual occurs after the chlorine dosage rate exceeds the demand created by reducing agents, ammonia, and organics b.p.
The orp measurement to ensure that your free chlorine can do it’s work is >650mv at the ideal ph of 7.2. It is calculated based on the pool’s orp and ph measurements. Other methods allow for the determination of free chlorine, chloramines, other chlorine species, and total available chlorine, and are suitable for total chlorine concentrations up to 5 mg/litre.
Free chlorine is the conventional chlorine that you add to your pool.
Your pool can have 1.0 ppm free chlorine and 800 orp with the use of enzymes, uv/ozone or hdo. Normal pool chlorine levels are usually around 1.0 ppm to 3.0 ppm, depending on the level of stabilizer in the water. In effect, free chlorine is the amount of chlorine that is free to kill harmful microorganisms in your swimming pool’s water. The initial point where free ‘available’ chlorine residual is present / detected breakpoint residual occurs after the chlorine dosage rate exceeds the demand created by reducing agents, ammonia, and organics b.p.
