Total chlorine testing in Ethiopia
Total chlorine is free chlorine plus the combined chlorine already bound to ammonia and organics. Running free and total on the same sample gives the combined figure by subtraction, which is how you tell a clean residual from one that is being consumed. Palintest supplies DPD No 1 for free and DPD No 3 for total, for both comparators and photometers.
Why it matters in Ethiopia
A supply that shows total chlorine well above free chlorine is spending its dose on contamination rather than on protection. Testing both on the same sample is the quickest way to separate a dosing problem from a water quality problem before anyone changes the dose.
