Trichloroisocyanuric Acid (TCCA) is available for use in swimming pools

Access to common chlorine generating products (HTH, NaDCC) is limited in Iraq and other Middle-Eastern contexts. Trichloroisocyanuric Acid (TCCA) is available however, marketed for use in swimming pools as 'clean pool 90'. The tablets are 200g, with available chlorine listed as 90% minimum. The dosage would need to be reduced considerably for, say a 10m3 water truck. My main concern, however, is whether this would be a suitable chemical for the chlorination of drinking water? To an untrained eye it looks similar to the Sodium dichloroisocyanurate (NaDCC) used in Aquatabs, but I'm unsure whether any of the bi-products might be hazardous in drinking water. As a slow release tablet the proposal would be to use this in a floating pot chlorinator.

Dichlor and  Trichloroisocyanuric Acid (TCCA)  have very similar chemical structures and are therefore both used in disinfection of water, whether that be pools, drinking water etc. The by-products formed by both will be the same as it's not the source of the chlorine that are the problem with DBP, but what the chlorine reacts with once it's dissolved in the water. Both dichlor and trichlor dissociate quickly in water (to form hypochlorous acid/hypochlorite and cyanuric acid). If you want a slower release chlorine tablet, a tablet based on calcium hypochlorite is a better option.
