The maintaining of water quality in distribution network is realized bypreserving in the whole network some residual chlorine concentrations forecast inLaw 458/2002.2. At a normal functioning, the necessary chlorine in network is assured byperiodical injections in the existing booster disinfection stations, established forthis state.3. In the case of some failures (pipe breaking etc) the residual chlorine distributionit is perturbed.4. With a personal program it is made evident the chlorine evolution in nodes of adistribution network for cases: network without the failures and network with thefailures on pipelines and the necessity to have the stand-by boster stations forchlorine injections in the cases of failures.5. The procedure may be applied for the elimination of pipelines, excepting thecases when appear the isolated nodes (situation that affects the graph connexion).References1.
